Infinities and singularities are equivalent when mass is absent and entropy (that is, randomness) is maximum, because in both states the ability of the universe to scale itself is lost.
It is called conformal equivalence. It means that the shape of everything in two systems is the same; the scale is indeterminate or irrelevant. Size can’t be measured.
Warning to the faint of heart: this essay will reveal ideas that might change the way some readers think about the universe. Keep an open mind.
What is the fate of the cosmos? Almost everyone agrees that it will expand exponentially, possibly forever. As it does, all matter will be sucked into black holes like water into bathtub drains where — perhaps over trillions of years — it will evaporate by a mechanism believed to produce Hawking radiation; mass converts into massless photons and radiates outward until every black hole evaporates and disappears.
Sir Roger Penrose, the brilliant mathematical physicist, has said that new satellite data might support his theory of Eons, which asserts among other things that the universe expands while black holes collect and evaporate away all matter; entropy (or randomness) increases to maximum.
At the termination of the Eon the universe cannot tell whether it is at its beginning or its end because it doesn’t know what size it is; all its metrics become equivalent to those found in the singularity that many speculate preceded the emergence of the Universe humans find themselves in today.
In the unimaginable heat of a singularity, the concept of mass also disappears; it becomes irrelevant. Energy dwarfs mass to overwhelm it; runaway entropy (randomness) goes to maximum.
With no mass the concept of scale disappears. Without mass all the gravitational degrees of freedom vanish. The universe doesn’t know what size it is or if it is any size at all.
Entropy (or randomness) of “the singularity” initiates the Big Bang in the same way as a maximally expanded and evaporated universe; the two states — infinity and singularity — are equivalent. They are not distinguishable; one is like the other and emerges from the other.
Both the singularity and the infinitely expanded universe are unable to determine how big they are because both lose the ability to scale themselves when matter is no longer present; both states have maximum entropy; the distribution of energy becomes infinitely random.
The result is that the expansion of a maximally expanded universe starts anew as if it were a singularity. A new “eon” begins at the end of each expansion; the universe expands in stages with the beginning of each stage indistinguishable from a singularity.
The universe seems to chug along like a smoking choo-choo train — almost like a perpetual motion machine that generates a brand new universe on the fading gasp of its last puff.
A contraction of mass into a singularity is a popular idea, but it never happens — not in this theory — except in black holes where all matter evaporates over time into the pure energy of Hawking radiation. In Penrose’s theory, only an infinite series of expansions following one upon the other from singularities indistinguishable by their metrics from maximally-expanded-universes will emerge.
It’s like a woman who gives birth to a daughter. The process repeats forever in the history of humans. Daughter buds from mother. Mother doesn’t contract to the size of a baby who then grows to become a new mother.
No, the process is continuous — one mother gives birth to a baby who grows to become a mother who births a new baby and on and on into an infinity of mothers that progress in a line of succession to the end of a time that has no end.
The universe expands until it becomes a singularity that expands into a new universe. The process never ends. There is no beginning and no end.

Does this idea by Roger Penrose resonate with the ring of truth to anyone? Roger has said that his idea is having some trouble catching on with bona-fide cosmologists.
For me, Roger Penrose’s idea feels like truth. His truth sets me free; everything falls into place; a weight is lifted from my shoulders when I think about what it means and why things might be the way they are.
Roger says that he is retired; the mathematics of his theory are worked out by his acolytes; they make predictions that are testable. One thing they predict are “Hawking points” or spots.
Hawking points are places where massive black holes have evaporated away every bit of the matter of the galaxies that fell into them. This radiation is concentrated; it will emerge to imprint the cosmic background of the universe that follows. The points or regions will spread to cover a circle in the sky that is four degrees across — close to eight times that of the Moon. Hawking points, if verified, will emit an energy that is ten to fifteen times more intense than the cosmic background radiation.
Hawking “spots” should be findable by humans. The radiation they represent bled into our universe from the universe that preceded and spawned them. Identifying Hawking spots will lend credence to the idea that a universe preceded ours and that another will follow in the far distant future — perhaps trillions of years from now.
Perhaps thirty candidates have been identified by recent satellite observations. The WMAP (Wilkinson Microwave Anisotropy Probe) satellite — illustrated above — and the newer Planck satellite have identified in the microwave background radiation (CMB) areas in space where the predictions of the Eon theory seem likely to be confirmed.
Roger claims that — absent mass — big and cold is equivalent to small and hot. The laws of thermodynamics hold in both worlds and are conformally equivalent. The mathematics are the same.
Roger Penrose has won 17 major awards in science; he has made major contributions in at least 30 areas of science and mathematics. The implications of his theory of conformal cyclic cosmology (CCC), if accepted by mainstream science, are worthy of a Nobel Prize.
I hope he lives long enough to receive it.
The video above, at 23:23, explains a consequence of the theory that dark matter (called erebons by Penrose) is required to make it work. Erebons are hugely massive compared to other atomic particles; they possess the mass equivalent of the eyeball of a flea. Sir Roger predicts that they decay and leave behind signals that will be confirmed by a focused analysis of data collected by the Laser Interferometer Gravitational-Wave Observatory LIGO.
Another interesting and rather strange consequence of the theory addresses the Fermi Paradox. From Wikipedia is the following reference:
”In 2015 Gurzadyan and Penrose discussed the Fermi paradox, the apparent contradiction between the lack of evidence but high probability estimates for the existence of extraterrestrial civilizations. Within conformal cyclic cosmology, the cosmic microwave background provides the possibility of information transfer from one Eon to another, including of intelligent signals within the information panspermiaconcept.”

THE EDITORIAL BOARD
UPDATE BY THE EDITORIAL BOARD:May 15, 2019; Victor T. Toth, the Hungarian software developer, author, and Quora guru of quantum physics wrote, “a photon has no rest mass, but it carries plenty of energy, and it has momentum. Its stress-energy-momentum tensor is certainly not zero. So it can be a source of gravity, it has inertia, and it responds to gravity. […] relativity theory predicts … twice the deflection angle for a photon in a gravitational field than the deflection of a Newtonian particle.”
Almost a century of experiments plus hundreds of upvotes on Quora by physicists seem to validate Victor’s argument.
The photon is known to be the only massless, free-moving particle in the Standard Model of physics. Other massless particles are the gluon, the graviton, and of course the Higgs, discovered in 2012 at CERN. Europeans plan to build a Higgs factory to learn more about them. Gluons mediate the strong force. They don’t propagate through empty space. No one has yet observed even a single graviton. Higgs give fermions like quarks their mass.
Photons have an electric and magnetic structure. They are electromagnetic pulses of energy that emerge from atoms when electrons drop from a higher energy state to a lower one. When electrons shed energy, a pulse of electromagnetic radiation is emitted — a photon of light.
Click pic for better view in new tab.
Photons of light can be emitted from atoms at different frequencies — colors when wavelengths fall within the narrow range that humans see. These frequencies depend on the energy of electrons, which exist in many differently configured shells (or orbitals) within both atoms and molecules.
Wavelengths of light felt but not seen are called infrared; other invisible frequencies fall into broad categories such as radio waves, microwaves, x-rays, gamma rays and so on — all require instruments to detect.
Electromagnetic radiation is the medium through which humans observe and interact with everything knowable in the universe. Humans live inside an electromagnetic bubble that they are struggling to understand.
One thing most physicists understand is that a disturbing 95% of the energy and mass of the universe comes from a source no one can see. Physicists observe the effects of invisible (dark) matter and invisible (dark) energy by measuring the unusual dynamics of galaxies and by cataloging the physical organization and expansion of the universe itself.
These measurements make no sense unless folks assume that a lot of gravitationally interacting stuff is out there which no one has yet observationally confirmed. The missing mass is not debris or dark stars. The most exaggerated conjectures about how much mass and energy is scattered among the stars won’t come anywhere near enough to explain forces that make galaxies behave strangely.
Dark matter and energy don’t seem to be electromagnetic. Dark matter, if it exists, interacts with the mass of two-trillion galaxies and seems to refract their emitted light. Humans are blind to all of it.
Scientists postulate matter they call WIMPS, MACHOS, axions, and erebons. Each has a few properties necessary to make the universe work as observed, but none have all the required properties except perhaps erebons, if Roger Penrose’s Conformal Cyclic Cosmology (CCC) is someday verified.
Space-saturating foam of micro-sized black holes is another idea some have proposed. The problem is that theorists believe tiny black holes might be too stable to radiate electromagnetic waves or gravity waves.
Micro-holes lie in a sort of crevice of invisibility — unobservable by LIGO and LISA style gravity-wave sensors, yet too massive for current and future particle-colliders like CERN to create.
Because micro-holes don’t radiate light at any frequency, light telescopes will never find them. No imagined interaction of micro-holes is able to generate gravity-waves with enough disruptive power in spacetime to be detected. The nature of physics seems to suggest that no technology can be developed to confirm or deny the black-hole foam idea.
Perhaps the same dilemma faces dark matter detection. We know it exists, but physics says we can never find it. It will always lie just outside our reach doing its work in an invisible universe no one will ever see.
Worse, not one of the proposed forms of “dark” matter has ever been observed or identified. It is likely that no experiment currently scheduled will detect dark matter, which many physicists believe is “out there” and makes maybe four parts out of five of all the matter in the universe.
It’s an incredible paradox for conscious humans to live in a universe where they are blind to almost every important thing that is happening within and around them.
Humanoids are like fish which spend their lives swimming in streams buried deep inside caves. Spelunkers like me know that certain species of cave fish have no eyes. They lack all ability to see their world — as do we, it seems. As intelligent as people are, they don’t yet build sensors capable of confirming their notions about what the universe might actually be at large scales or small.
Oh well… someday maybe new discoveries will make our predicament evaporate away. The universe will reveal itself to humans, as we knew it would. Our dream to fully understand reality will come true.
Some day.
Scientists have sensible mathematics to show that if electromagnetic particles are massless, they must travel at an upper limit, called “c“. Over decades, folks decided that this constant is the speed of a photon in a vacuum; they decided that photons have no internal rest mass and travel in vacuum at a speed limit — the speed of light.
The truth might be more mysterious. No one knows what the upper limit of “c” is, because no one knows with certainty that space is truly empty or that massless particles exist.
When physicists say that certain particles are massless, they sometimes mean that they don’t interact with the Higgs Field, which is known to give mass to fermions, like quarks. They don’t mean they don’t have energy, specifically kinetic energy, which is a form of inertial mass, right? They also aren’t saying photons don’t interact gravitationally. They do, in a special way described by the geodesics of spacetime in Einstein’s General Relativity.
More on this idea later.
British physicist Brian Cox wrote in his book Why Does E = mc2 ? that the question about whether photons have rest mass is not yet settled.
It’s true that more than a few reasonable people seem to believe that photons traveling freely in the vacuum of space are massless. If they truly are then the permittivity constant “ε” in Maxwell’s equation can be established for electro-magnetic particles (like photons).
The formula below is used to calculate the speed of a massless electromagnetic particle; it is thought to be a maximum speed.
For now, ignore the μ term. It is the permeability (resistance) of vacuum to infusion by a magnetic field, which is determined by experiment. It is sometimes called the magnetic constant.
Epsilon (ε} is the permittivity (resistance) of vacuum to an electric field. It is sometimes called the electric constant.
”c” is the so-called ”universal speed limit.” It is called the lightspeed constant.
These three numbers — μ, ε, and c — help to define the maximum velocity of an electromagnetic wave, which most people believe is the archetypal photon (of light). They assume that the photon packet travels at the maximum allowable speed in a vacuum.
A problem with this view is that no one has proved that space is free; or that space has no weight; or that photons have no rest mass; or that undiscovered particles formed from forces other than electricity and magnetism don’t exist. A few scientists have said that there might be no such things as free space or massless photons. It is also possible that space presents less resistance to other phenomenon yet to be discovered.
The idea that ”dark” matter and energy must exist to make the universe behave the way it does is compelling to many physicists. If true, it is possible — though light travels nearly 300 million meters-per-second — it is not traveling at the maximum speed of a generic, massless particle. The electric constant (ε)might need to be adjusted.
A decrease in the permittivity (resistance) of space (ε) — made obvious by inclusion of vast number of photons in the cosmic microwave background — drives ”ε” to be smaller and ”c” to be larger, right?
New particles, dark and as yet undiscovered, might do the same. The consequences could be significant.
Determining the upper speed of a massless particle requires a form of circular reasoning that is currently based on the measurement of the velocity of photons in a vacuum, which is called the speed of light.
The measured velocity of light in a vacuum is now an established constant of nature with a fixed value that doesn’t change regardless of the frame of reference. Modern labs have measured both the frequencies and wavelengths of various colors of light; multiplying the two numbers together always yields the same result — the speed of light.
Knowing the speed of light permits physicists to establish a value for ε by working backwards in the wave equation to solve for the electric permittivity of space. The value of “ε” falls easily from Maxwell’s Equations to a precision of 12 places.
It can’t be any other way. But is it the right way?
Here’s the problem: Physicists have measured mass in photons during experiments at the linear accelerator lab at Stanford University, SLAC.
In superconductors, photon mass has been measured to be as high as 1.2 eV.
Photon mass has been observed in wave guides and in plasmas.
Fact is, photons have inertial mass, which is a measure of their energy as calculated from their wavelengths or frequencies. In relativity theory, energy and mass are measured in the same units, electron-volts, because in the theory, mass and energy are equivalent.
Click this link to view CLOSER TO TRUTH interview with Raphael Bousso.
Cosmologist, Raphael Bousso, believes that empty space has weight, which is a measure of the cosmological constant, which is a measure of dark energy.
Space seems to be saturated like a sponge with something that gives it energy or force or weight if you will. The weight of empty space determines the size of the universe and some of its fundamental laws. Universes beyond our own with different weights of space can be larger or smaller and obey different rules.
Most physicists agree that photons become massive when they travel through transparent materials like glass, where they slow down by as much as 40%.
The problem is that these observations conflict with both the Heisenberg and the Schrodinger view of quantum mechanics, which is the most tested and confirmed model physicists have. Modern ideas seem to work best when photon mass is placed on the energy side of the mass-energy column. Otherwise, the presence of internal mass suggests that photons can be restrained to a defined size, which drives their momentums to infinity.
The truth is that it is not possible to prove that photons are massless. The stress-energy-momentum tensor in Einstein’s equation of General Relativity implies that photons can be both the source and the object of gravity. I’m referring to this tensor as “mass” and leaving it there for others to dispute. A rabbit hole for courageous readers to explore is the concept of pseudotensor, which this essay will avoid.
It is also not true that a photon can never be at rest either. Lab techs do unusual things with photons during experiments with lasers and superconductors — including slowing photons down and even stopping some (with supercooled helium-4). Right?
Another problem is the electromagnetic nature of light. The electric part of a light-wave carries enough energy to move an electron up and down. The magnetic part carries the same energy but its motion creates a force that pushes electrons outward in the same direction as the light. It’s why light-sails work in space. Oscillating magnetic fields push light forward. Otherwise, light might stand in one place and simply jiggle. But is light-speed the best magnetic fields can do?
Electromagnetism could be irrelevant in the search for an upper speed limit “c“, because “c” might prove to be the result of an unknown set of particles with properties outside the current boundaries of the Standard Model.
Massless particles, — undiscovered ones anyway — might not be electromagnetic. Humans might be biologically unfit to detect them; unable to measure their properties.
For those who might be rolling their eyes, remember that physicists claim that 95% of the mass and energy required to make the universe behave the way it does is missing. They call the missing stuff “dark” because they can’t find it. Excuse me should anyone catch me rolling my eyes.
Some theorists have speculated that “dark photons” might exist to help fill in the gaps. The popular TV show How the Universe Works actually repeated the idea in an episode of its latest series. The writers were probably referring to axions, which some physicists propose are similar to photons except that they have mass and are slower moving.
Photons are bosons. They are force carriers for electrons, correct?
Maybe folks should try to accept the notion that nothing in physics prevents bosons like photons from having mass or from taking on mass when they whiz over and through atoms and molecules (in glass and water, for example) where some physicists conjecture, they stimulate the release of polaritons in their wake. Jiggling electrons that lack the energy to jump states emit polaritons, which seem to add enough equivalent mass to photons to slow them down. Think of polaritons as light-matter wavelets.
Massive, gravitationally interacting photons are not required to be “dark.” If photons are the darkmatter, axions are unnecessary to solve certain problems both in cosmology and the Standard Model. No experiment will find them.
I mentioned that three other particles are presumed to be massless: the gluon, the graviton, and the Higgs boson.
To review, the gluon is not easily observed except in particle colliders where it lives briefly before decaying into other particles; it is confined among the protons and neutrons in the nuclei of atoms. The graviton, on the other hand, has never been observed. The Higgs boson was discovered in 2012. CERN plans to build a Higgs factory someday to explore its properties.
The only particle available to physicists right now that enables them to establish the permittivity of space and compute the velocity of massless particles is the photon.
That’s it.
If the photon has internal mass, i.e., rest mass, everything changes.
Let’s hop into a rabbit hole for a moment and go back a step: What if massless, non-electromagnetic particles mediate entanglement, for example? Wherever paired electrons are found, entanglement rules, right?
Everyone knows that entanglement violates laws of logic and physics. No one can make sense of it.
What if massless non-electromagnetic particles entangle the electromagnetic particles of the subatomic world? If they travel a thousand or ten-thousand times the speed of light, they will present an illusion over short planetary scales that entanglement is instantaneous. No instrument or lab will detect the difference.
What are the consequences if massless non-electromagnetic particles travel at a billion times the speed of light? Maxwell’s equations won’t apply to particles like these.
Because it seems that speeds of subatomic particles like photons are able to increase as their masses approach zero, it is possible that “c” could be orders of magnitude faster than the speed of a photon — that is, the speed of light — if it turns out that photons harbor tiny but significant rest masses.
I’m not advocating this notion. Let’s crawl out of the rabbit hole. I’m suggesting only that such a state of affairs is possible, because the assumption that photons at rest are massless — that internal mass of photons is always zero — though reasonable and desirable to justify models, is not yet settled according to some physicists.
And there is, of course, the phenomenon of entanglement which no one can explain.
Here’s speculation that should blow the mind of any thinking person: Could photons, if shown to have internal mass, be the stuff that make the galaxies move in the non-intuitive ways they do?
Yes, some physicists argue that the upper limit on the internal (rest mass) of a photon must be less than 10-52 kilograms, which is about 5.6E-17 eV for folks who think that way. (Multiply mass by the speed of light twice to make the conversion and divide by 1.60218E-19 Joules per eV.)
5.6E-17 eV doesn’t seem like much mass at all until folks realize that the minimum number of photons in the universe might be as high as 1090. This number is ten billion times the number of atoms in the universe. It means that the internal mass contribution from photons alone could easily exceed 1038 kilograms if the upper limit proposed by some is used to perform the calculation.
Do the math, anyone who doesn’t believe it.
Guess what?
Prepare for a letdown.
Based on the conjectured eVs, the mass of all material in the visible universe is in the neighborhood of 1053 kilograms. The video below will help the reader understand how this value and others are calculated. The mass of the visible universe turns out to be 1,000 trillion times more than the conjectured internal mass of all photons.
Think about it.
Is it enough mass to account for the galaxy anomalies seen by astrophysicists? To any reasonable mind the answer is obviously, no. But this conclusion is not the end of the story.
Those who study astronomy know that the outer stars in galaxies seem to move at roughly the same speed as the inner. Yet the galaxies aren’t flying apart.
By way of contrast, the planets in solar systems like ours travel slower the farther away they orbit from their sun. If Neptune orbited as fast as Earth, it would fly away into deep space.
A recalibration to account for the internal mass of photons of light (which seems to always be discounted) does not at first blush offer the gravitational heft that astrophysicists require to make everything on galactic scales fall into place.
The cosmic background radiation — which is nothing more than photons that decoupled close to the beginning of time — saturates the universe like vinegar in a sponge, right? It is distributed evenly across all space for as far as human-built instruments can see.
The CMB makes an annoying hum in radio telescopes no matter their focus or where they point. Photons with tiny internal masses or no mass at all will have no influence on the understanding by astrophysicists of how the universe behaves.
Neutrinos, which seem to oscillate between three (or perhaps four) as yet undetermined massive states, might at times take on values below the actual mass-value of photons — if photons turn out to be more massive than most believe. The laws of physics require that neutrinos less massive than massive photons, should they exist, must travel superluminally (faster than light). Agreed?
Several “discredited” observations have reported faster-than-light neutrinos, including the unexpected outcome of the infamous OPERA experiment, which inspectors eventually blamed on a loose fiber-optic cable that was ever-so-slightly longer than it should have been.
OK. It seems reasonable. Who can argue?
Scientists who believe that superluminal neutrinos actually exist don’t speak up, perhaps out of fear for their careers. They probably couldn’t get their opinions published anyway, right?

Crackpot ideas that later prove valid is how science sometimes works. It’s how science has become the mess that it is — a chaos of observations that can’t make sense out of 95% of what is going on all around; a plethora of experimental results that don’t quite match the work of theorists.
The super-brilliant people who paint the mathematical structures of ultimate reality rely on physicists to smear their masterworks with the muds of perturbation, renormalization, and a half dozen other incomprehensible substrates to get the few phenomenon folks think they understand to look right and make sense. Theory and experiment don’t seem to match-up as well as some folks think they should more times than not.
A minor recalibration based on the acceptance of photons as quantum objects with tiny, almost unmeasurable masses will not change ideas about the nature of the universe and what is possible, because the upper-bound on photon masses might be undervalued — perhaps by a factor of billions.
Theorists like Nima Arkani-Hamed work on abstract geometries called amplituhedrons to salvage notions of massless particles while simplifying calculations of scattering probabilities in quantum mechanics. It seems to me like hopeless adventures doomed to fail. But in fairness so did Columbus’s exploration for new worlds.
To be a serious candidate for dark matter, a typical microwave photon should have an average mass of nearly .05 eV (electron volts), which is about 9 x 10-38 kilograms. If multiplied by the number of photons ( 1090 ), the photon masses add almost miraculously to become 85% of the theoretical mass of the universe.
(1E90)*(9E-38) = 9E52. (9E52) / .85 = 1E53 kg.
It’s the same number conjectured by dark-matter advocates.
To qualify for dark matter means that a typical or average photon must have close to one ten-millionth of the mass of an electron.
Only then does everything fall into place like it should.
Pull out the calculator, anyone who doesn’t believe it.
Einstein, in his famous 1905 paper on special relativity, showed that mass is equivalent to the energy of an object divided twice by a constant, which is “c” squared, right?
Later, he added a second term to the internal energy of a particle which is its inertial energy, pc2 . Simplified, this term equals hf for a massless photon. The total energy of any object is the square root of the sum of its internal energy and its inertial energy.
If Einstein is taken at his word, then the inertial mass of a photon is a function of its characteristic frequency — i.e. the inertial mass of a photon is equal to
where “h” is the Planck constant and “c” is the speed of light. The internal mass, should any exist, can be discounted.
An argument can be made from Einstein’s equations that the mass of a photon might be times larger. A factor of 1.414… won’t change the argument. It strengthens the point but is, in the end, not important enough to include in an article that is already overly long. Curious readers can review the reasoning in my essay General & Special Relativity.
If the average photon has an inertial mass of .05 eV, it requires that — all else being equal — the combined photon energy in a non-expanding universe would lie in the range of infrared light, a frequency in this case of 12E12 Hz, which is sometimes referred to as far-infrared.
(Set equivalent-mass equal to .05 eV (8.9E-38 kilograms) and solve for frequency.) The frequency approaches the lower energy microwave part of the light spectrum.
Note:For perspective, one eV is the energy (or mass equivalent) of a near-infrared photon of frequency 242E12 Hz, which approaches from below the higher-energy visible-light part of the light spectrum.
The mass equivalence of the inertial energy of 1E90 infrared photons is sufficient to hold the universe together to prevent runaway expansion caused by repulsion due to the gravity constant Λ in Einstein’s equation for General Relativity.
Do the math.
I know what some people might be thinking: Didn’t the 29 May 1919 solar eclipse, which enabled observers to confirm Einstein’s theory of General Relativity, demonstrate that photons lack internal mass? Didn’t Eddington’s experiment prove wrong Newton’s idea that photons, which he called corpuscles, were massive objects?
Maybe. Maybe not. Maybe internal mass isn’t necessary. There is enough energy in the inertial term of Einstein’s equation to yield the required mass.
Unlike massive particles where internal energy far outweighs inertial energy, for photons, inertial energy is dominant. Even if science admits to a small amount of internal mass in photons, it is their inertial energy that dominates.
I found a good mathematical argument for light mass on Quora by Kyle Lochlann, an academic in relativity theory. Here is the link:
Be sure to read comments to his answer — especially those who find math incomprehensible, which might be nearly everyone who reads my blog.
After all, Newton’s theory of gravity predicted that the light from stars would deflect near the Sun at only half what Eddington’s experiment clearly showed. Eddington’s eclipse proved Einstein’s theory — the geodesics of spacetime bend in the presence of massive objects like stars.
Many concluded that photons followed the geodesics of spacetime, because photons lacked mass equivalence of any kind. Newton erred about pretty much everything involving gravity and light, some said.
But their conclusion can’t be right, can it? Doesn’t their conclusion ignore what the math of Einstein’s formulas actually says?
Won’t it make more sense to say that the geodesics of spacetime constrain and overwhelm whatever internal and inertial mass photons might possess? Doesn’t it make more sense to convert the frequency-related inertial energy of photons to mass to better explain their behavior near objects like the Sun?
Evidence exists that light-mass is a thing and that it matters. Einstein included a mass-equivalence term for light in his tensors for general relativity. Frank Wilczek, MIT Nobel laureate, is famous for insisting that the mass of anything at all is its energy content. The energy of light is in its frequency, its momentum, which is a measure of its mass.
It’s true that light does not seem to interact with the Higgs field. Nevertheless, the energy of light seems to interact gravitationally with ordinary matter. The interaction is not measurable when photon numbers are small. When photon numbers are huge, perhaps it is.
A single photon in the presence of the Sun has no chance. When 10E90 photons saturate a space that is almost entirely devoid of matter, photons can shape a universe — especially when their number is 10 billion times the number of atoms.
It seems possible, at least to me.
According to data gathered by the NASA WMAP satellite, ordinary matter in the observable universe amounts to a little more than 1/4 of a neutron per cubic meter of space. It amounts to 253.33E6 electron-volts of mass. Everything else WMAP observed was “cold dark matter” and “dark energy”.
How many .05 eV photons does it take to flood a cubic meter of space with enough mass-equivalence to reduce the mass-energy of 1/4 of a neutron to 15% of the total? How many photons are required to sum to 85% of the energy WMAP attributed to “cold dark matter”? It turns out that the number is 34 billion photons per cubic meter.
The question is: how many photons are there?
The observable universe has an estimated volume in the neighborhood of 1E80 cubic meters, right? Yes, it might be as much as 4 times that number.
The lower-bound number of photons in the observable universe is 1E90. It might be ten times more.
It turns out that the number photons per cubic meter in the universe must be somewhere close to 25 billion. 25 is pretty darn close to 34. Since all the numbers are estimates with large margins of error, it’s possible that everything will fall into place as it should if and when the statistics of the universe are ever known with precision.
Could photons of light might be the “cold” dark matter everyone is searching for?
A single neutron has no chance when it is bathed in 136 billion .05 eV photons, which surround and envelop it on all sides from every direction. It makes a kind of quantum scale Custer’s Last Stand for random neutrons, right?
When scientists look at the universe today, they see an accelerating expansion. They see in the cosmic background radiation photons that have slipped from infrared into longer, less energetic microwave wavelengths which no longer have enough mass-equivalence to hold the universe together.
As light stretches into longer and longer wavelengths through interaction mechanisms such as Compton scattering and other processes (like the push of “dark energy” or the less popular gravitational tug of parallel universes), light frequencies and energies diminish.
Eventually, when the total of all light falls below an average frequency of 12E12, the equivalent mass of the 1E90 primordial photons loses its grip; it becomes unable to hold the universe together.
Near the beginning of time when photons were orders-of-magnitude higher in frequency than now, their stronger gravitationally-equivalent-masses pulled together the structures astronomers study today, like stars and galaxies.
But now scientists seem to be witnessing a runaway expansion of the universe. Light has stretched and dimmed into the microwave and radio-wave frequencies where its mass-equivalence is unable to hold together the universe as it once was.
Because we can’t detect it, isn’t it possible that dark energy and dark matter don’t exist? That is to say, the idea that dark matter and energy are necessary to account for observations is no more than a conjecture made necessary by a misbehaving universe of unusual galaxies. But direct observational evidence for dark matter and energy is the part of the conjecture that is missing. No one has ever seen any.
What astronomers are observing instead is faraway galaxies that existed billions of years ago when the mass-equivalent energy of photons was greater than it is now.
The intact universe of galaxies seen in the night sky today, which is photographed with high-resolution space-borne telescopes, is not up to date in any sense at all, except that it is the view of an ancient past that goes back almost to the beginning of time depending on how deep into space anyone looks.
Everyone who cares about astronomy knows it’s true.
To qualify as a candidate for dark matter means that a photon must have close to one ten-millionth of the mass of an electron. It seems like a reasonable ratio, right?
In the Standard Model, only neutrinos are less massive than electrons. No one knows what the mass of each of the three “flavors” of neutrinos is, but when added they are less than 0.12 eV — about 2.4 times the equivalent-mass of infrared photons and about one four-millionth of the mass of electrons. It seems possible to me that the mass of at least one of the flavors of neutrinos will be less than the conjectured equivalent-mass of an infrared photon packet.
Neutrons and protons are, by contrast, 2,000 times “heavier” than electrons.
I am asking working physicists to reexamine estimates that claim the mass of a photon can be no more than trillions of times less than the mass of an electron.
The claim can be found at the back of articles in science journals as well as in blogs across the internet. For me, the idea seems ridiculous on its face. The energy-equivalent mass of photons varies with frequency, but only the lowest energy radio wave photons can hope to approach the low equivalent-mass estimated in the latest publications.
Scientists might want to revisit the mass of a photon and the methodology of its measurement. The stakes are high, and science doesn’t have many options. Hope — like the energy of ancient photons — is fading.
Science would be served best if scientists started from scratch to reexamine every assumption and lab procedure. The search for dark matter has become an expensive and compulsive quest that seems futile, at least to me. Several costly experiments have reached disappointing dead ends, which are reviewed in the “VICE on HBO” video located near the start of this essay.
What if photons of light really are the dark matter, which is hiding in plain sight waiting to be discovered by anyone who dares to look at the problem with fresh eyes?
What if the delay between the observations of the CMB (cosmic microwave background) and the structure of the universe is a natural disconnect in time and space that misleads folks to believe that mass must be “out there”, when it has in fact long since dissipated?
From another perhaps opposite perspective, what if photons are instead stimulating emissions from virtual particles as they travel at fantastic speeds through the vastness of space? What if these emissions add mass to photons sufficient to bring them to the “dark matter” threshold, as they do in materials like glass?
Such a state of affairs would imply that not all photons travel the same speed in the so-called vacuum of “empty” space. It is a heretical idea, for sure — a can of worms, perhaps to some, but hey! — you can catch a lot of fish with a can of worms.
A photon is a packet of electromagnetic oscillations built-up from many frequencies. Superposition of these frequencies adds to give a photon its characteristic frequency from which its equivalent mass can be calculated. Right?
Use imagination to think of the many ways a higher “speed limit” that is mandated by the existence of massive photons might work to stimulate the interest of a space-traveling civilization to explore the universe, which ordinary folks begin to understand is more accessible, more reachable than anyone thought possible.
Consider the number of inexplicable phenomena that would make sense if particles thought to have zero internal mass don’t really exist, and photons, gluons, gravitons, and Higgs bosons aren’t the only ones.
Recalibration might save a lot of time and effort in the search for the putative missing energy and mass of the universe.
Should “dark” particles exist whose internal mass is less than that of photons, they will likely move at superluminal speeds that make them difficult to track. To influence stars, their number would have to dwarf photons. Such an idea strains credulity.
A counterproposal by Roger Penrose speculates that dark matter particles might have the mass of the eye of a flea; he calls them “erebons.” These particles are electromagnetically invisible, but their huge masses relative to other particles in the Standard Model make them gravitationally compelling.
Erebons decay; evidence for their decay should be showing up in data collected by LIGO detectors.
So far persuasive evidence for erebons has not been found.
For scientists and explorers, the access-barrier to a universe shaped and configured by massive photons will most certainly shrink — perhaps thousands to millions of times.
The stars and galaxies that people believed were unreachable might finally fall within our grasp.
Or — perhaps less optimistically and more cynically — the mass-equivalent energy of 1E90 photons might by now be so severely degraded that nothing can save a universe that has already come undone and flown away into an abyss that humans will never see.
The radiation-evidence from a catastrophe of disintegrating galaxies that has already occurred won’t reach Earth-bound viewers for perhaps billions of years.
Should humans survive, our progeny — many millions or billions of years from now — may “see” in the vastness of space a cold and diminished radio-wave radiation that hums in a soul-less vacuum devoid of galaxies and visible light. Microwave light will by then be nothing more than a higher-pitched, prehistoric memory.
Roger Penrose says that the fluid dynamics of an exhausted universe devoid of matter will become indistinguishable from the singularity that gave its start. A new universe will ignite from the massless, radiation-ashes of the old.
Human-nature forces us to want to know more; most folks want to search for and find the answers to the questions that will determine the fate of all life on Earth and in the vast stretches of spacetime that remain beyond our reach.
Is the universe within our grasp, or has it already disintegrated?
People assume they see nothing, but in every case, when they look closely — when they investigate — they find something… air, quantum fluctuations, vacuum energy, etc.
QUESTION: Is this a large-scale view of the universe or a sub-microscopic view of vacuum energy and quantum fluctuations? Can anyone tell? The universe is not empty. Everywhere anyone looks, at all scales, it seems like there is no such thing as nothing.
Everyone finds no evidence that a state of nothing exists in nature or is even possible.
Physicists know this for sure: there can be no state of absolute zero in nature — not for temperature; not for energy; not for matter. All three are equivalent in important ways and are never zero — at all scales and at all time intervals. Quantum theory — the most successful theory in science some will argue — claims that absolute zero is impossible; it can’t exist in nature.
There can be no time interval exactly equal to zero.
Time exists; as does space (which is never empty); both depend for their existence on matter and energy (which are equivalent).
Einstein said that without energy and matter, time and space have no meaning. They are relative; they vary and change according to the General Theory of Relativity, according to the distribution and density of energy and matter. As long as matter and energy exist, time can never be zero; space can never be empty.
People can search until their faces turn blue for a physical and temporal place where there is nothing at all, but they will never find it, because a geometric null-space (a physical place with nothing in it) does not exist. It never has and never will. Everywhere scientists look, at every scale, they find something.
We ask the question, Why is there something rather than nothing?
Physicists say that nothing is but one state of the universe out of a google-plex of other possibilities. The odds against a state of nothingness are infinite.
Another glib answer is that the state of nothing is unstable. The uncertainty principle says it must be so. Time and space do not exist in a place where nothing exists. Once the instability of nothing forces something, time and space start rolling. A universe cascades out of the abyss, which has always existed and always will. Right?
Think about it. It’s not complicated.
People seem to ignore the plain fact that no one has ever observed even a little piece of nothing in nature. There is no evidence for nothing.
Could it be that the oft-asked question — Why is there something rather than nothing? — is based on a false impression, which is not supported by any evidence?
Cosmic microwave background radiation is a good example. It’s a humming sound that fills all space. Eons ago CMB was visible light — photons packed like the molecules of a thick syrup — but space has expanded for billions of years; expansion stretched the ancient visible light into invisible wavelengths called microwaves. Engineers have built sensors to hear them. Everywhere and at every distance microwave light hums in their sensors like a cosmic tinnitus.
Until someone finds evidence for the existence of nothing in nature, shouldn’t people conclude that something exists everywhere they look and that the state of nothing does not exist? Could we not go further and say that, indeed, nothing cannot exist? If it could, it would, but it can’t, so it doesn’t.
Why do people find it difficult, even disturbing, to believe that no alternative to something is possible? Folks can, after all, imagine a place with nothing in it. Is that the reason?
Is it human imagination that explains why, in the complete absence of any evidence, people continue to believe in the possibility of null-spaces — and null-states — and empty voids?
Photons are mysterious quantities of light which have both wave and particle properties. The odd thing: physicists say they have zero rest mass. All their energy comes from their frequencies, which are invisible fields of electricity and magnetism that oscillate in a symbiotic dance of orthogonality.
A physical packet (quantum) of vibrating light (a photon) can be said to have zero mass (despite having momentum, which is usually described as a manifestation of mass), because it doesn’t interact with a field now known to fill the so-called vacuum of space — the Higgs Field.
Odder still: massive bodies distort the shape of space and the duration of time in their vicinities; packets of vibrating light (photons), which have no mass, actually change their direction of travel when passing through the distorted spacetime near massive bodies like planets and suns.
Maybe people cling to their belief in the concept of nothingness because of something related to their sense of vision — their sense of sight and the way their eyes and brains work to make sense of the world. Only a tiny interval of the electromagnetic spectrum, which is called visible light, is viewable. Most of the light-spectrum is invisible, so in the past no one thought it was there.
The photons people see have a peculiar way of interacting with each other and with sense organs, which has the effect of enabling folks to sort out from the vast mess of information streaming into their heads only just enough to allow them to make the decisions necessary for survival. They are able to see only those photons that enter their eyes. Were it otherwise humans and other life-forms might be overwhelmed by too much information and become confused.
Folks don’t see a lot of the extraneous stuff which, if they did observe it, would immediately disavow them of any fantasies they might have had about a state of nothingness in nature.
If we were not blind to 99.999% of what’s out there, we wouldn’t believe in the concept of nothing. Such a state, never observed, would seem inconceivable.
The reason there is something rather than nothing is because there is no such thing as nothing. Deluded by their own blindness, humans invented the concept of ZERO in mathematics. Its power as a place holder convinced them that it must possess other magical properties; that it could represent not just the absence of things that they could count, but also an absolute certainty in measurement that we now know is not possible.
ZERO, we have learned, can be an approximation when it’s used to describe quantum phenomenon.
When the number ZERO is taken too seriously, when folks refuse to acknowledge the quantum nature of some of the stuff it purports to measure, they run into that most vexing problem in mathematics (and physics), which deconstructs the best ideas: dividing by zero, which is said to be undefined and leads to infinities that blow-up the most promising formulas. Stymied by infinities, physicists have invented work-arounds like renormalization to make progress with their computations.
Because humans are evolved biological creatures who are mostly blind to the things that exist in the universe, they have become hard-wired over the ages to accept the concept of nothingness as a natural state when, it turns out, there is no evidence for it.
Anyone who has witnessed the birth of their own child understands that the child does not emerge from nothing, but is a continuation of life that goes back eons.
The phenomenon of life and death has added to the confusion. We are born and we die, it seems. We were once nothing, and we return to nothing when we die. The concept of non-existence seems so right; the state of non-being; the state of nothingness, so real, so compelling.
But we are fools to think this way — both about ourselves and about nature itself. Anyone who has witnessed the birth of their own child understands that the child does not emerge from nothing but is a continuation of life that goes back eons. And we have no compelling evidence that we die; that we cease to exist; that we return to a state of nothingness.
No one remembers not existing. None of us have ever died. People we know and love seem to have died, physically, for sure. But we, ourselves, never have.
Those who make the claim that we die can’t know for sure if they are right, because they have never experienced a state of non-existence; in fact, they never will. No human being who has ever lived has ever experienced a state of non-existence. One has to exist to experience anything.
Why is there something, not nothing? Because there is no such thing as nothing. There never will be.
A foundation of modern physics is the Heisenberg Uncertainty Principle, right? If this principle is truly fundamental, then logic seems to demand that nothing can be exactly zero.
Nothing is more certain than zero, right? The Uncertainty Principle says that nothing fundamental about our universe can have the quale of certainty. The concept of nothing is an illusion.
An alternative to nothing, is something. Something doesn’t require an explanation. It doesn’t require properties that are locked down by certainty. Doesn’t burden-of-proof lie with the naysayers?
Find a patch of nothing somewhere in the universe.
It can’t be done.
The properties of things may need to be explained — scientists are always working to figure them out. People want to know how things get their properties and behave the way they do. It’s what science is.
Slowly, surely, science makes progress.

Afterthought: The number ZERO is a valid place holder for computation but can never be a quantity of any measured thing that isn’t rounded-off. When thought about in this way, ZERO, like Pi (π), can take on the characteristics of an irrational number, which, when used for measurement, is always terminated at some arbitrary decimal place depending on the accuracy desired and the nature of the underlying geometry.
Working with ZERO is tricky. Dividing by ZERO is never allowed, which is what was done in the second-to-last line to give the result: 2 = 1. Remember: (a – b) = 0, because a = b.
The universe might also be pixelated, according to theorists. Experiments are being done right now to help establish evidence for and against some specific proposals by a few of the current pixel-theory advocates. If a pixelated universe turns out to be fact, it will confound the foundations of mathematics and require changes in the way small things are measured.
For now, it seems that Pi and ZERO — indeed, all measurements involving irrational numbers — are probably best used when truncated to reflect the precision of Planck’s constant, which is the starting point for physicists who hope to define what some of the properties of pixels might be, assuming of course that they exist and make up the fabric of the cosmos.
In practice, pixelization would mean that no one needs numbers longer than forty-five or so decimal places to describe at least the one-dimensional properties of the subatomic world. According to theory, quantum stuff measured by a number like ZERO might oscillate around certain very small values at the fortieth decimal place or so in each of the three dimensions of physical space. A number ZERO which contained a digit in the 40th decimal place might even flip between negative and positive values in a random way.
The implications are profound, transcending even quantum physics. Read the Billy Lee Conjecture in the essay Conscious Life, anyone who doesn’t believe it.
One last point: quantum theory contains the concept of superposition, which suggests that an elementary particle is everywhere until after it is measured. This phenomenon — yes, it’s non-intuitive — adds weight to the point of view that space is not only not empty when we look; it’s also not empty when we don’t look.

Comment by the Editorial Board:
Maybe a little story can help readers understand better what the heck Billy Lee is writing about. So here goes:
A child at night hears a noise in her toy-box and imagines a ghost. She cries out and her parents rush in. They assure her. There are no ghosts.
Later, alone in her room, the child hears another sound, this time in the closet. Her throbbing heart suggests that her parents must be lying.
Until she turns on the light and peeks into her closet, she can’t know for sure.
Then again, maybe ghosts fly away when the lights are on, she reasons.
In this essay, Billy Lee is trying to reassure his readers that there is no such thing as nothing. It’s not real.
Where is the evidence? Or does nothing disappear when we look at it?
Maybe ghosts really do fly away when we turn on the lights.
Twelve launch-capable space agencies (having as members about thirty countries) are, among other tasks, looking for alien life inside the solar system. They are exploring the four planets closest to the Sun: Mercury, Venus, Earth and Mars, which have three moons among them, and the five outer planets: Jupiter, Saturn, Uranus, Neptune and Pluto, which have one-hundred-and-sixty-three.
With so many moons and planets, the hope is that one of them will harbor life.
(Click pic to enlarge in new window.) Some recommend the Drake Equation to calculate odds that intelligent life which can communicate across space might exist elsewhere in the Milky Way Galaxy where our solar system is located.
Of the 166 moons and nine planets in the solar system, probes have managed to land on only five: Venus, Mars, Jupiter, Earth’s moon, and Titan (a moon of Saturn).
Just three moons are located in the Goldilocks zone where most scientists believe life has the best chance to take hold. Two orbit Mars at the outer edge of the habitable zone and are probably too cold and irradiated for life. The third moon orbits Earth.
(Click pic to enlarge.) Each column contains the orbiting moons of each planet (and a few other objects) inside the solar system.
Six moons in the solar system are comparable in size to the moon of Earth: Ganymede, Titan, Callisto, Io, Europa and Triton. All the rest are tiny with very little gravity — the force that can hold an atmosphere.
The twelfth largest rocky object in the solar system after Earth is Titania of Uranus, named for the Queen of the Fairies in Shakespeare’s Midsummer Night’s Dream. The moon is nearly a thousand miles in diameter. A 175 pound person on Titania takes on the weight of a newborn baby — a mere six pounds twelve ounces.
Few places in the solar system have enough gravity to hold a human securely, let alone an atmosphere.
No life has been found on any moon — or on any planet (except Earth) thus far. During the next several hundred years, humans will continue to look for life in the solar system should technology and civilization survive and advance.
The Kuiper Belt — which starts at Neptune and extends past Pluto — is a region that is home to an estimated 100,000 bodies of frozen methane, ammonia, and water.
Editors’ Note:(August 2016) The explorer spacecraft,New Horizons, flew by Pluto on July 14, 2016; it will fly by a Kuiper Belt object in January 2019.
Freeman Dyson — physicist, mathematician, and astronomer — has suggested that life might be pervasive in the Kuiper Belt and be easily detected once spacecraft get there. People wait and wonder.
Editors’ Note: (December 2018) Current analyses of data from the Pluto flyby describe a living, dynamic planet with a nitrogen atmosphere and a subsurface ocean. Portions of the surface are smooth with no signs of meteor impacts. Water-gushing volcanoes are common.
The solar system lies within a large disc-shaped galaxy called the Milky Way, which folks can see edge-on in the night sky should they travel out into the countryside away from well-lit cities, which tend to wash out vision.
It might surprise some readers to learn that no one really knows how many stars are in our galaxy. Credible astronomers believe the number to be somewhere between one-hundred and four-hundred billion — a huge range of uncertainty.
No one knows how many stars are similar to the sun. No one knows how many planets there are, or how many moons. Despite a lot of reporting and speculation, humans know almost nothing about the Milky Way.
Space is vast, and astronomers have few telescopes and satellites to accomplish the enormous job of taking it all in and cataloguing what they discover.
3.75 billion years from now, the Andromeda galaxy will collide with our own Milky Way. In this artist’s conception, Andromeda Galaxy is on the left; the Milky Way Galaxy is to the right.
Lack of knowledge about the details of our own galaxy helps to explain why it is difficult to understand the universe as a whole. When I first published this essay in late summer 2014, astronomers estimated that between a hundred and two-hundred billion galaxies populated the visible universe (the estimate is now known to be wrong).
Editor’s Note:On October 1, 2017 CBS News was among the first to report to the public that the Hubble space telescope had detected as many as two trillion galaxies — ten times more than previous estimates.
Two-trillion galaxies — and all the other objects in the universe that lie outside the local area of our own galaxy —are far away and too fuzzy for astronomers to know almost anything about them. The galaxies are out there, true, but the numbers are staggering. The small amount of data astronomers have already gathered is overwhelming scientists’ abilities to process and make sense of it all. And they are just getting started.
The Webb Telescope is scheduled for launch on 30 March 2021. Image is an artist’s rendition featured on Wikipedia.
Civilization is in the very first stages of placing sensors into space which eventually will help astronomers to learn more. One — the James Webb space telescope — is scheduled to launch sometime during the 2020s. Its purpose? — to tear down the 400-million-light-years-after-the-Big-Bang limit of the Hubble telescope.
Humans are going to be able to look back to the beginning of time, at long last. Understanding the process that brought us here is going to expand dramatically. Until then, the Drake equation (see illustration at beginning of the essay) and other speculative tools remain not much more than intriguing diversions.
New sensors like the Webb telescope will upgrade human understanding and bring a new realism that promises to sweep away much of the science-fiction people drink to satiate their thirst for ultimate knowledge.
Most articles, television shows, and movies that purport to portray the universe are (to risk overstating it) kind-of scammy. They seduce a gullible and curious public, which is hungry for answers about the universe that no one yet has.
The science community has a vested interest in public funding; they tend to go-along with dubious depictions to pander popular support. Claims that astronomers today understand fully the nature of the universe are ludicrous. The universe is vast. Much of its matter and energy that scientists believe is “out there” can’t be found — not yet anyway.
Most stars are too faint to see with unaided eyes. The closest star system to our Sun, Proxima Centauri, is too faint to see without a telescope.
Three out of four stars in the galaxy are probably red dwarfs. Red dwarfs burn essentially forever but are smaller and much cooler than the Sun, which makes them impossible to observe without special infrared detectors.
These infrared detectors are launched into outer-space beyond Earth’s atmosphere to avoid being blinded by the infrared heat radiating off Earth’s surface.
Proxima Centauri main star. Image by Hubble Telescope.
Red dwarfs seem to be emitting solar flares that are a thousand times more energetic and frequent than those generated by stars like the Sun. They emit light in frequencies not useful for plant photosynthesis — the basic life-support process on Earth.
It’s difficult to see how Earth-style life could get started and survive inside a red dwarf planetary system. No one knows what percentage, if any, of red dwarf stars have planets suitable for life.
Canon 85mm photo of Proxima Centauri three-star system by Skatebiker on English Wikipedia.
Red dwarfs live for thousands-of-billions of years. The Sun’s lifespan is eight to ten billion years — a tiny fraction of a red dwarf’s.
The Sun is similar to — who knows? — maybe one in five stars in the galaxy. It’s an optimistic guess, based on sampling and wishful hoping. Astronomers seem to agree that the Sun ranks as one of the largest stars in the Milky Way.
Statistical sampling of two-trillion galaxies argues that the Milky Way galaxy is also among the largest. A full 90% of all galaxies are smaller.
Calculations involving galaxy-motion and gravity suggest that when astronomers look at the cosmos, they aren’t seeing ninety-five percent of what’s out there. Physicists call the missing stuff dark energy and dark matter. Something that no one has yet been able to detect seems to be distorting the rotation of galaxies and disrupting the metrics of space-time.
The universe seems to be expanding, and the expansion is accelerating. Where is the missing mass and energy that drives the expansion? No one knows.
Perhaps parallel universes are stacked on every side against our own. They might swarm like bees around a hive. The gravitational pull of their enormous masses might be pulling our own universe apart. Galaxies inside our universe might be falling toward massive structures that lie outside our field of vision beyond a kind of event horizon.
Again, no one knows. It’s speculation. Today the expansion is described by a simple constant added into Einstein’s equation for General Relativity. A constant seems too simple, at least for me. It describes but doesn’t explain.
Einstein’s equation accounts for the accelerating expansion of the universe by including a term called the ”cosmological constant”. It is the Greek letter lambda ( Λ), which is multiplied against every member of the metric tensor, ”g” and then added to the left side of the equals sign, which is the side of the equation that describes the shape (curvature) of spacetime. The right side describes the distribution of mass / energy in spacetime.
Many of the galaxies that are visible from Earth are tens-of-thousands of times farther away than the farthest stars in our own galaxy, the Milky Way, which astronomers say is at least 100,000 light years across — a distance of six-hundred-thousand trillion miles. The galaxy is perhaps 200 light years thick, but its center is thicker still — about 10,000 light years.
If the Milky Way was shrunk to the diameter of a ten-inch plate, the plate would assume a thickness of a few human hairs but at the center it would thicken to the size of an egg-yolk.
To put these distances into perspective, the latest space probes, which travel at roughly twelve miles-per-second, are not capable of escaping the gravity of our solar system until they are mechanically slung by multiple encounters with planets to a velocity greater than 27 miles per second. At that speed, crossing the Milky Way takes nearly 700 million years.
What the Milky Way might look like if photographed by an extremely powerful telescope from the galaxy Andromeda, which is two-and-a-half million light-years from Earth.
The Milky Way is one galaxy in what astronomers have learned is a universe of two trillion.
Until scientists know more — and it could be decades or even centuries from now — prudence and the scientific method advise odds-makers to use the most conservative estimates, not the most optimistic, to speculate about intelligent life in the cosmos.
Until evidence accumulates that is more compelling than what is available today, plugging conservative numbers into the Drake equation, or any other speculative tool, always seems to give the same discouraging result — a number so small it might as well be zero.
No intelligent life that can communicate across space should exist in our galaxy or anywhere else in the universe. None. Yet, here we all are. It’s kind of mysterious, at least to me.
Substituting less conservative numbers yields a different result. Intelligent civilizations could number in the thousands or even millions. No empirical evidence supports such optimism, at least not yet.
Planets and Sun are shown to scale in this model. Distances are not. From left to right, largest to smallest: Jupiter, Saturn, Neptune, Uranus, Earth, Venus, Mars, Mercury, and Pluto. Pluto — recently demoted to the status of a ‘’dwarf planet” — has been re-argued for planet-hood by some cosmologists because the recent NASA fly-by showed Pluto slightly larger and more planet-like than previously thought.
Looking closer to home within our own galaxy, astronomers in 2003 discovered Sedna, which some think is another dwarf-sized planet orbiting far beyond Pluto.
Astronomers seem to discover new planet candidates every other month — Eris and Makemake are two more Pluto-sized objects out of hundreds that come to mind.
In 2014 Caltech astronomers presented evidence for another planet they called the ninth planet, which might be an object ten times the mass of Earth orbiting in a highly elliptical orbit at the farthest reaches of the solar system.
Regardless of what astronomers continue to discover, it seems likely that the Sun will always contain at least 99% of the mass in the solar system.
Earth is fortunate to orbit a star that is located in a less active region of space than many other stars in the Milky Way. The Sun lies safely between two spiral arms that are bright because of ongoing birthing of new stars. The location lies halfway from the center of the galaxy to its outer edge.

Although stars are spread more or less evenly throughout the Milky Way, life-destroying cosmic events are less likely in regions where stars aren’t being born. Earth lives between bright spirals in a zone of relative inactivity, which has enabled the evolution of eukaryotic one-celled life to progress to intelligence, then civilization, and finally to space exploration over the past billion-and-a-half years.
Earth has a number of unusual features that make it a good candidate for highly evolved life. One important feature is its nearly circular orbit around the Sun, which helps Earth avoid the catastrophic temperature variations characteristic of the more egg-shaped (elliptical) paths of some of the other planets, like Mars.
Only the orbits of Venus and Neptune are more round than Earth’s. Mar’s orbit is five times less round. Of all the solar objects, only Neptune’s moon Triton is known to have for all practical purposes a perfectly circular orbit.
Another advantage for Earth is its 300-mile thick atmosphere of nitrogen and oxygen, 80% of which lies within 10 miles of its surface. Nitrogen and oxygen make up 99% of Earth’s atmosphere. These gases are opaque to non-electrically-charged, high-frequency light.
Nitrogen molecules block high-frequency, ultra-violet light while oxygen molecules, slightly smaller, block higher-frequency (shorter wave-length) x-rays and gamma-rays, which can be lethal to living organisms.
A three-atom form of oxygen molecule known as ozone helps to absorb in the upper atmosphere a dangerous-to-life, lower-frequency-band of ultra-violet light that nitrogen can’t block.
In the distant past — during the Carboniferous Period 300 to 360 million years ago — Earth’s atmosphere held 60% more oxygen than it does now, which provided more shade against damaging high-energy light. Dinosaurs and large insects — like dragonflies with three-foot wing-spans — thrived in the highly-oxygenated air they breathed.
It is one of the wonderful ironies of our planet that the oxygen which empowers the biology of life also defends it against the physics of life-destroying high-energy light and cosmic rays that are always raining down from outer space.
Without atmospheric moisture and greenhouse gases, Earth’s average temperature would fall to 100°F below zero.
In contrast to nitrogen and oxygen, which block high-frequency light from reaching Earth’s surface, carbon-dioxide, methane, and water vapor trap low-frequency light (infra-red light, or heat) and prevent it from radiating (or escaping) into space.
These green-house gases work like a blanket to help keep Earth at a constant temperature. Carbon dioxide, though rare, is heavy compared to oxygen and nitrogen. It tends to cling close to Earth’s surface where it is respirated by plants. Without atmospheric moisture, methane, and carbon dioxide the temperature of Earth would average 100°F below zero and vary widely between day and night as it does on the Moon.
Although water vapor and carbon dioxide make but a tiny fraction of the atmosphere, they have a significant impact on the planet’s ability to retain heat when their concentrations increase in the atmosphere. Exhaust from commercial jet aircraft, believe it or not, contributes greatly to the concentration of carbon dioxide and water vapor in the eight-mile highs of the atmosphere where these jets fly.
After the terrorist attack on 911, the government suspended all flights over the United States — including those by commercial aircraft — for four days. The skies over America cleared themselves of clouds and turned deep blue. Temperatures dropped.
I was amazed to observe these changes develop so quickly after all flying was suspended. It took about two weeks for aviation to return to pre-attack intensity. With the return of aviation, familiar weather patterns followed.
Unlike Earth, the planet Venus has so much carbon dioxide that its surface broils with heat. An explorer would have to hover thirty-seven miles above its surface to experience atmospheric pressures and temperatures similar to those on Earth.
By contrast, the atmosphere of Mars, though almost entirely carbon dioxide, is thin — only 1% as thick as Earth’s. Even so, near their surfaces the density of carbon dioxide is 15 times higher on Mars than on Earth — enough to grow plants and — if poisons in the soil can be avoided — terraform the surface should humans decide.
Although Mars is cold, especially at night, its carbon dioxide atmosphere enables daytime temperatures to sometimes reach 85° F during summer in its southern latitudes. The problem is that any plants that might grow in Martian soil must endure bombardment by dangerous-to-life high-frequency light and cosmic particles. Also, Martian soils are poisoned by perchlorates. The soil is useless for agriculture though perchlorates could be broken down to provide a source of oxygen.
I should mention argon, which is 1% of Earth’s atmosphere. It is formed by the radioactive decay of a rare isotope of potassium in Earth’s crust. It is transparent to infra-red heat, so it has no effect on global warming. It is heavy — like carbon dioxide — so it clings to the surface, but its small atoms, widely spaced, do little to prevent the escape of infra-red radiation.
Another asset that gives Earth an advantage for life is its large moon whose gravitational field acts like a vacuum cleaner to suck up cosmic-debris like asteroids and comets that might threaten to strike. Only Jupiter, Saturn and Neptune are similarly equipped.

The moon stabilizes Earth’s tilt as it orbits the sun. The tilt is about 23.4°, which is why Earth has seasons. The tilt swings back and forth a few degrees over periods of 41,000 years. This variation is stable enough to permit life to survive and evolve despite the periodic generation of ice-ages.
Computer simulations of a moonless Earth show that with no moon to stabilize it, tilt variations could approach 90°. Dramatic destabilization has emerged in some simulations that make it difficult to imagine how advanced life could evolve and survive the climate extremes that might result from chaotic wobbling.
The Moon is receding away from Earth at a rate of almost two inches per year. It will take at least a billion years for the motion of Earth to destabilize. It seems that humans have time to figure something out.
Sadly, the sun gets brighter and less massive with each passing day. Over the course of a billion years, Earth will move farther from the sun to conserve its angular momentum. Meanwhile, the warming sun will overtake Earth’s great escape to evaporate its oceans and make the planet uninhabitable.
Looking at coming events from a more optimistic perspective, people can probably agree that a billion years is a long time. The species-human is likely to be extinct by then anyhow. So why worry?!
Another life-enhancing feature of Earth is its large, open, ice-free, salt-water oceans. Most scientists believe salt-water oceans provide safe habitat for evolving life.
Earth’s oceans make up three-fourths of the planet’s surface. In addition to providing a vast incubator for life, oceans reduce the probability that space-debris will fall onto land.
Odds are that debris will fall into the oceans where it is rapidly cooled and rendered harmless. Should debris strike land and throw up clouds of dust and ash to block the sun, the oceans provide a safety-blanket of thermal protection.
This photo of Titan’s surface is the only picture taken at the surface of a moon or planet that is farther away than Mars.
Besides Earth, only Titan — one of Saturn’s many moons — has open oceans (of liquid methane and ethane) on its surface. These oceans are more like shallow seas or lakes, estimated to be about five-hundred feet deep. Scientists think Titan has a salty sub-surface water ocean, as well.
NASA reported this year that another moon of Saturn, tiny Enceladus (310 miles in diameter), holds a six mile deep subsurface ocean — confirmed from Cassini fly-bys. Its over one-hundred geysers are what is populating Saturn’s E-ring. Data from the geysers indicate that the ocean is warm and salty and saturated with organic molecules. Analysis by Cassini instruments is on-going.
Of the moons of Jupiter, only Europa, Ganymede, and Calisto are thought to harbor salt-water oceans.
Europa is known to have a salt-water ocean, but it is covered by miles-thick ice.
Ganymede, the largest moon in the solar system, is believed to have a 500 mile deep salt-water ocean that lies beneath a crust 125 miles thick. The crust is thought to be a rock and ice mixture.
Scientists suspect that Callisto has a salt-water ocean, but it might be sandwiched between ice layers sixty or more miles beneath its surface.
Only the oceans of Earth are open, un-frozen, and deep enough (averaging three miles) to protect Earth against most encounters with meteors and other space-debris.
Fortunately for Earth, the solar system itself contains a massive structure that helps to protect and shield it from danger. It is Jupiter, the large and strongly gravitational planet, which like the moon pulls away space-debris that might otherwise zoom toward Earth to imperil all life. Observations suggest that comets strike Jupiter every couple of years. Comets that don’t strike are gravitationally deflected out of the solar system more often than not.
Another fortunate feature: Earth has, geologists say, a molten iron-core that emits a strong magnetic field to deflect life-destroying, electrically-charged cosmic particles, that have energies, some of them, approaching those of baseballs traveling sixty miles-per-hour. Cosmic particles accelerated the process of ripping away Mar’s atmosphere. Without a magnetic field the Mars atmosphere is defenseless against cosmic erosion.
As for Earth, high energy particles that do manage to blast through it’s magnetic shield (magnetosphere) are often scattered and rendered harmless — fortunately — by collisions with the oxygen molecules in Earth’s dense atmosphere.
One exception is muons, which are byproducts of particle collisions high in Earth’s atmosphere that are energetic enough to burrow down to hundreds of yards beneath Earth’s land surfaces and oceans. In rare heavy bombardments at high altitudes, muons can increase risks of cancer and cataracts to pilots and their passengers. Muons are like electrons except that they are 207 times heavier and much shorter-lived.
Sun’s solar wind deflected by Earth’s magnetosphere. NASA art.
The magnetosphere is strong enough to deflect the solar wind, which can strip away all or part of the atmosphere of any planet that lacks one (like Mars).
The magnetosphere is effective and strong, because it is huge and surrounds Earth out to five Earth-diameters on the side facing the sun; one-hundred Earth-diameters on the side opposite. In any small area of space, though, a simple bar-magnet is fifty times stronger.
The solar wind isn’t all bad. As it radiates outward from our Sun, it forms a huge magnetic bubble called the heliosphere that extends 3.5 billion miles past the Kuiper Belt.
Inside this Sun Bubble the rest of the solar system is protected from massive cosmic particles that pour in from the two trillion galaxies of stars that make the universe. The Sun bubble deflects to shade our solar system in relative safety.
The heliosphere of the Sun works together with the magnetosphere of Earth and its oxygenated atmosphere to break up and knock away the vast majority of cosmic particles (high-speed protons and atomic nuclei) that would otherwise rip Earth-life to shreds.
Absent the magnetosphere, life could evolve safely only in the deep oceans or far below the surface of Earth. Stated differently: a strong, protective magnetic field is essential for the survival of surface life on any planet.
Large solar flares are known to have enough energy to kill exposed astronauts. It’s one of many reasons NASA doesn’t send people to Mars, which lacks a magnetosphere. Mars is under relentless bombardment of atomic particles that can damage the atoms and molecules in the cells of a human body.
All planets have magnetic fields of various strengths except Venus and Mars. The iron in the core of Mars is believed to have frozen solid, or nearly so, hundreds of millions of years ago, which helped force its protective magnetic field to collapse.
Venus retains its molten iron-nickel core, but the planet lacks tectonic action in its crust. The heat of its core can’t escape through its surface, which prevents in its molten center the emergence of the turbulence essential to make a planetary dynamo of sufficient power to rev-up a magnetosphere.
It’s a shame that both Mars and Venus lack magnetospheres, because both planets have attributes that might otherwise make them good candidates for life.
Earth’s core is huge — it rivals the entire planet of Mars in size. The inner third of the core — the center — is already frozen solid. It is believed to be pure iron. The core is freezing itself solid from the inside out.
The rest of the core is hot liquid iron and nickle, mostly, with some sulfur and other impurities mixed in. It circulates in complex eddies, which generate the magnetic fields that protect Earth by deflecting the solar wind.
The flow of currents in the molten metal is made stable and more reliable by the unusual plate tectonics peculiar to Earth. Gaps in Earth’s crustal plates allow heat to escape from volcanic valves, which help to maintain a controlled roil in the eddy currents to produce the dynamo that drives its magnetosphere.
The only moon known to have a magnetic field is Jupiter’s Ganymede. Jupiter itself harbors a field fourteen times more powerful than Earth’s. The giant planet’s four largest moons orbit inside it, where they are protected from the solar-wind and low frequency (low-energy) cosmic particles. By contrast, Mercury’s magnetic field is one-hundred times less powerful than Earth’s.
Despite these several advantages for sustained evolution of life, Earth has the apparent disadvantage of a volatile climate which, scientists believe, has turned cold and icy during several extended periods. I mention this volatility to remind people that the circumstances that have enabled life to advance to the technological civilization of today are complex and not obvious.
Until scientists are able to tease out of history what is actually important and significant for the development of advanced life, no one can know what the rest of the universe may have in store — unless we travel out into space and explore it.
I want to believe: we will find the way.
Here’s the problem. The closest stars to the Sun are twenty-five trillion miles away. To escape the solar system, engineers must build spacecraft that can accelerate to 27 miles per second. At that speed the nearest stars, Proxima Centauri, and the binary star system, Alpha Centauri, are 30,000 years distant.
How are humans going to explore the universe? How are we going to answer the questions about our place in the cosmos, when we can’t travel to the nearest stars?
There are trillions of stars, most of them many millions of times farther away than these, our closest neighbors. It seems hopeless that anyone will ever know the answers to the basic questions about the universe that so many are asking.
Still, in my heart of hearts, I want to believe we will find a way.

Editors Note:November 2017; NASA announced that the latest count of galaxies might be as high as two trillion. The velocity required by spacecraft to escape the Milky Way galaxy from Earth (our planet is 25,000 light years from the galaxy center) is 342 miles-per-second. At this velocity the nearest galaxy — Andromeda — is a flight of 2.28 billion years. There are two-trillion galaxies more!
It doesn’t really matter. Here’s why:
The Parker Solar Probe scheduled for launch in 2018 will require seven gravity-assists from Venus over a period of six years to reach a velocity of 120 miles-per-second before it embarks on a 2024 suicide mission into the outer atmosphere of the Sun.
Venus and the Sun combined can’t accelerate the Parker Solar Probe to the galaxy-escape velocity of 342 miles-per-second.
Minus gravity-assists, the fastest vehicles in development today by space-flight engineers will accelerate to speeds less than 27 miles-per-second — the escape velocity required to exit the solar-system. Without gravity assists that take years to rev-up, we humans can’t leave our own solar system, which is arguably the tiniest imaginable fraction of the Milky Way galaxy.
The good news is that life-forms in far-away solar systems face the same obstacles. If they are hostile, humans can be assured that they will have a difficult time getting here.
The bad news is that humans are trapped. The Milky Way Galaxy is a prison. We can’t escape, at least not yet; most likely, not ever. The escape velocity of the Milky Way Galaxy from Earth exceeds 340 miles-per-second — nearly three times the velocity that the Parker Solar Probe will be traveling when it is finally able to bury itself inside the Sun.
In an earlier article, Sensing the Universe, we asked the question: What exactly is the Universe? Most folks seem to agree that brains process the input of senses to create a useful but completely false view — a hallucination, really — of reality.
For one thing, sensations in minds of colors like yellow impart no knowledge whatsoever of the electromagnetic radiation that triggers the color experience.
Colors do not exist in the physical universe at all, right? Color is an illusion that brains conjure to help make certain choices — to enhance survival strategies, probably. Colors exist inside minds, nowhere else, I argued.
Readers can revisit the earlier essay if they want to better understand this follow-on, which is going to push everyone a few steps farther.

Is the universe able to exist apart from conscious life?
Does anything exist apart from conscious experience?
Is it possible to know what exists in a Universe where conscious life is completely absent?
What consequences follow should all answers turn out to be, “no”?
How can this be?
The terms conscious life and consciousnessdeserve to be defined. For now, it’s better to leave the terms undefined except to say that anyone who reads this essay and believes they understand at least parts of it probably qualifies as conscious life.
As for Consciousness, it doesn’t necessarily require life, does it? How about intelligence? The simplest definition of Consciousness might be awareness. Most scientists and engineers agree that machines can be made aware when they are built right.
But this essay goes further. It suggests that neither machines nor biology are required to generate either awareness or conscious life.
Is there anyone reading this essay who believes I’m right?
Consciousness is likely to be a fundamental and basic property of reality.
It’s true.
Consciousness might be the most fundamental and basic property of the universe. Many philosophers of science agree. Every thinking person in their gut feels on some level that reality is ultimately immaterial, don’t they?
I think so.
Can something bubble forth from nothing?
These lead-off questions are important.
Why?
Imagine it was demonstrated either by direct experiment or mathematical deduction that — apart from consciousness — the universecould not exist.
Kurt Gödel’s Incompleteness Theorem has dazzled mathematicians since 1931. Douglas R. Hofstadter wrote in a preface to his Pulitzer Prize winning Gödel, Escher, Bach: An Eternal Golden Braid that any formal system based on mathematics (which he believed the universe was) ”…must spew forth truths — inadvertently but inexorably — about its own properties, and … become self-aware…”
What if Hofstadter was right, or at least partly right? What might be some implications?
Well, to begin, it seems necessary that consciousness must exist first before the universe can get going; or at least exist in the same spacetime to give the universe meaning.
What else might logically follow?
Well, again, if consciousness exists first (or concurrently), it must have always existed. Otherwise, the conclusion must be that consciousness bubbles-up from nothing. Human logic seems to require that something not bubble-forth from nothing.
Said another way, if something cannot exist apart from a conscious observer, then consciousness exists forward and backward in spacetime, forever — even if it turns out that the physical universe does not.
Consciousness might have mysterious and not yet understood properties — eternal and fundamental. And it might not be confined to awareness alone. To precede a physical universe, consciousness might have attributes related to causation. A long lineage of quantum physicists bends toward the view that particles don’t emerge from fields in the absence of measurements by conscious observers.
Erwin Schrödinger, the physicist of yesteryear who wrote the quantum wave equation, believed that consciousness existed independently of human beings. Consciousness in his view had a singular quality about it.
No matter how divided the mind, or how schizophrenic an individual, or how many personalities someone might display during their lifetime, consciousness seems always to be singular, Schrödinger wrote. It didn’t manifest itself in pairs or sets or multiples.
Subatomic particles are imaginary constructs invented by scientists to explain the results of experiments. No one understands what quantum objects are or what they ”look” like. Science has yet to reveal the underlying secrets of reality. It cannot explain how life began. It is not yet able to locate consciousness, or explain why it works the way it does.
Consciousness always has the same familiar qualia as it did in childhood. Even when an individual transforms and grows, learns new skills, gathers knowledge, and is reborn a dozen times — physically and psychologically in life’s many stages of metamorphosis and regeneration — consciousness feels the same. The aura doesn’t change.
To Schrödinger, consciousness was unique, singular, stable, unchanging, and consistent from one human being to another and over any one individual’s lifetime. The quality of consciousness had an invariance about it that seemed atypical for biologically driven attributes.
Consciousness, to Schrödinger, was something people shared, even plugged into, much like people today plug their televisions into a cable outlet.
To Schrödinger, consciousness had to be a phenomenon that lay outside the brain, not inside, as many of his contemporaries insisted. People were simply guessing wrong about consciousness, he said.
It wasn’t the first time. Ancient people once thought the center of consciousness lived inside the heart — until surgeons of the Spanish Inquisition discovered it didn’t.
Consciousness, to Schrödinger, was something people shared, even plugged into, much like folks today plug their televisions into a cable outlet. He attributed his insight to passages read from the Upanishads of ancient India.
Erwin believed that consciousness was an absolute and fundamental feature of the universe; something basic and simple; simpler even than an electron or quark, for example. It could not be accounted for in terms of anything else; certainly not in physical terms of something like what would become the Standard Model, for example.
I mention this view now to let readers know that ideas which might seem strange (and disturbing to some) are coming to anyone who gathers enough courage to read on.
Now might be the time to mention that many animals act like they are conscious. Self-awareness — measured by recognizing oneself in a mirror — might not bea reliable test of awareness in animals. Recognition of self in a mirror is a test of intelligence, which is something different.
Most scientists today seem to believe consciousness is a property of brains, not the universe itself.
Anyway, the prevailing view of science in the 21st century is to take a physical view of the universe and conclude that conscious life arises from physical processes on Earth, certainly, and perhaps many other places in the cosmos yet undiscovered. Since conscious life is assumed to be complex — more complex than particles and forces — consciousness must have developed after the physical universe, not before, most scientists reason.
Science takes the view that complexity evolves from simplicity; it has a direction similar to the arrow of time. Consciousness — invisible; never observed; undiscoverable; lacking any physical attribute that can be measured; indescribable; unknowable except to the individual who experiences it — is assumed to have evolved from physical objects and forces, which can be observed and measured, discovered and manipulated.
The legendary scientist, Francis Crick, who described the DNA molecule, suggested that the Claustrum might be the structure that brings the brain into the state called ”consciousness.” No one knows if he was right, because experiments to find out would be lethal, not to mention unethical and illegal.
Consciousness is like a ghost who inhabits complex life forms on Earth — the holistic result of a grand evolution in the complexity of physical brains. Consciousness is a feature of the brain, science insists; it lies inside the brain though it cannot be found there.
Some have suggested that a structure called the claustrumcouldplay a role. It is an assemblage of mostly identical neurons that looks like a potato-chip embedded in the brains of some animals, including humans. From it run connections to many important structures.
But the function of the claustrum remains a mystery. It might orchestrate the firing of neurons to flip the switch to consciousness. Then again, it might not. No one knows what it does.
Another possible candidate for the fabrication of consciousness is the micro-scaffolding, called microtubules, which support the internal structure of many kinds of cells. They permeate the interiors of soma cells and the root-like structures of brain neurons called dendrites.
NOTE from the EDITORS: This 13-minute video is a somewhat technical explanation of microtubules; interplay with neurons starts at 10:30.
Both Stuart Hameroff — an MD and emeritus professor for anesthesiology and psychology at the University of Arizona — and Nobel Prize winner Sir Roger Penrose — physicist, mathematician, and collaborator of the late Stephen Hawking — are promoting the notion that quantum properties of microtubules inside nerve cells of the brain and heart are the drivers for electrical dynamics of nervous-systems in people and other organisms.
These quantum level structures enable the simplest one-celled organisms — which lack neurons but are scaffolded by microtubules — to perform the neural functions of life.
Penrose and Hameroff are making a claim that the putative quantum behavior of microtubules, which are orders of magnitude smaller than neurons, might enable the subjective feeling of awareness and control that conscious life seems to share.
Some have argued like Schrödinger — see essay What is Life? — that some kind of structures (perhaps micro-tubules) might exist and function like quantum sensors to detect and interact with conjectured proto-consciousness, which is likely to be quantum in nature and foundational to a physical universe like ours.
The putative quantum nature of the brain is a reason why some theorists think entanglement and superposition explain much of the unusual behavior of conscious life.
Other scientists have stepped forward to label as absurd any notion that consciousness is quantum in nature or an intrinsic property of the universe; a few have ridiculed Dr. Stuart Hameroff and Roger Penrose, for aiding and abetting what seems to them like quackery.
But not all.
Erwin Schrödinger believed consciousness was a fundamental property of the universe.
Consciousness is not, in contemporary consensus, a phenomenon that lies outside the brain (like light), which can be experienced by a life-form once it achieves a certain level of physical development.
Eyes, for example, evolve to detect a narrow band of electromagnetic radiation, which — though pervasive within the universe — is unknowable to life-forms who lack sense organs for vision.
The consensus of modern science seems to be that consciousness is not an intrinsic phenomenon of the universe that can be detected (or imbibed, to use a better word) by physical organisms after they attain a high level of biological complexity.
Most scientists would argue that a physical universe can teem with activity unobserved for billions of years. The universe may not exist for conscious life to observe until the universe creates it through an ageless process of evolution.
At the point when the universe manufactures conscious life, it acquires for itself a history and a definition determined by the life it brought forth, which now observes it. This idea seems reasonable until one understands that some of the most brilliant philosophers, many fluent in mathematics and sciences, disagree.
One popular opponent of this view is Australian David Chalmers who argues that consciousness is a fundamental requirement for a physical universe like our own; it predates life-forms such as humans.
Even a hard-headed scientist like Erwin Schrödinger, who gave the world the mathematics of the quantum wave function, imagined that quantum structures in the brain, should they exist, serve simply to connect (or entangle) the living to universal consciousness, which resides somewhere, somehow, outside brains, where it operates as the, perhaps, fundamental, intrinsic, and foundational property of the cosmos.
The smartest people who ever lived disagree about the nature of conscious life.
Why wouldn’t they?
None understand anything at all about what everyone calls the “hard problem.”
Matter and antimatter are in theory produced in a one-to-one ratio, which ought to ensure their mutual destruction. But if matter and antimatter emerge within spherical volumes, then their ratio must depend on the irrational number, π. The graininess of space determines to what decimal-place π rounds-off, which determines whether the ratio permits a little more or a little less matter than antimatter. In our universe the ratio may have gone positive and stayed that way for a long time. SOURCE: The Billy Lee Conjecture. To balance positive-matter and keep the universe in a zero-sum configuration, negative energies (like gravity) result, according to the late Stephen Hawking. Recall that energy and matter are equivalent per Einstein’s equation, . Energy and massless particles like photons of light are equivalent based on their frequencies; Einstein included this feature in his less familiar but expanded equation . These equivalencies are clues that might enable someone to properly explain how the universe works on large scales and small.
Virtual Particles
It might be worthwhile to pause a moment to examine another phenomenon about which physicists are in actual agreement. Taking a more wide-angled view of the universe should make conscious-life easier to think about and understand.
Because when anyone thinks about it — really thinks about it — what could be more unlikely than something dead — like a singularity that goes bang — bringing forth something that is not only alive but also conscious?
One popular explanation is that of science writer, Timothy Ferris, who wrote in a recent National Geographic article, ”Space looks empty when the fields languish near their minimum energy levels. But when the fields are excited, space comes alive with visible matter and energy.”
In other words, the apparent vacuum of space is an illusion that misleads observers about an underlying and hidden reality that includes pervasive fields of energy permeating all of space.
The positive and negative values of matter, energies, and forces of the entire universe sum to zero, theoretical physicist Stephen Hawking wrote. But quantum uncertainties at every Planck-sized point in space oscillate about zero between positive and negative values. At this moment countless fluctuations across the vast expanse of space are skewing the balance — perhaps temporarily — into the structure of space and time, matter and forces, scientists observe.
My question is this: what is it that skews the balance of quantum fluctuations into a universe where humans can live in and observe? What brought the universe with its array of unlikely settings and its many arbitrary but exquisitely fine-tuned constants into the precise configuration required for the emergence of conscious life?
Stephen Hawking, former British Director of Research at the Centre for Theoretical Cosmology within the University of Cambridge; born January 8, 1942; died March 14, 2018. The Editors
As Stephen Hawking made plain to non-scientists in his book, The Grand Design, there’s really nothing here. Not when it’s added up. The values of matter and energy add to zero. He speculated that the odds against a universe configured like ours could be as high as 10 followed by 500 zeros to one.
The number is so large that it might as well be infinity. It’s not possible for most people to say a number this big using only the words billion or trillion. They have to say a billion times a billion 56 times in a row without losing track — probably impossible. Or they could say a trillion times a trillion 42 times — not much easier.
It turns out that the only sure way to create a universe with conscious life by pure chance is to start with a multiverse populated by a number of universes equal to 10 followed by 400 zeroes multiplied by the entire number of protons and neutrons that exist in the one universe we know about — this one. Take a deep breath.
According to Stephen Hawking, developing a reasonable chance for a universe with human-like life might require a multi-verse containing a large number of other universes. Hawking estimated that it is equal to the number of protons and neutrons in our own universe multiplied by 10 followed by 400 zeroes. (As a practical matter, the number is equivalent to an infinity.) Some theorize that a multi-verse might resemble a vast ocean of foam with each bubble being a unique universe with its own fundamental constants, number of dimensions, and physical laws.
As mentioned before, everything observed in the universe seems to be the result of quantum uncertainties that hover around and sum to zero, both on small scales and large. Can uncertainties around a zero-sum reality give rise to consciousness?
Is it really uncountable trillions upon uncountable trillions of universes in an unimaginably large multi-verse that makes the existence of conscious human beings inevitable? Or is there some other mechanism which has drawn a single universe suitable for life out of the quantum fires of non-existence?
It’s a simple question. If the concept of a multi-verse turns out to be fantasy, then what is left? One solution to consider is that some form of conscious-life, fundamental and eternal, skewed the numbers and somehow imagined the universe into existence by a process that seems thus far unknowable.
What else could it be?
Think about it.
Without an unimaginably large number of universes, it’s not really possible for physical laws to configure themselves by chance into a universe with conscious life. It’s not realistic. Stephen Hawking said the odds are overwhelmingly against it; the chance might as well be zero, he said.
Take another breath.
EDITOR’S NOTE: July 4, 2019: Billy Lee published an essay today describing Roger Penrose’s conjecture about the origins of the Universe called Conformal Cyclic Cosmology (CCC) or ”Eon Theory.” Recently launched satellites are gathering supporting evidence but the conjecture has not yet been embraced by mainstream cosmologists.

Stephen Wolfram, British computer scientist and physicist, born August 29, 1959.
Stephen Wolfram in his book, A New Kind of Science, argues that a simple sequence of iterative quantum events which repeat and branch out according to a simple set of rules could, given enough time, generate a complex universe. Discovering what these simple rules might be has so far proved daunting. Presumably, the rules and events for such a sequence would have natural origins and create many universes out of the quantum uncertainties present in natural sets of initial boundary conditions.
Who knows?
One thing is certain. If it is ever proved that multi-verses are fantasy — if it is demonstrated that our universe is the only universe — then the argument for a conscious-life which has somehow imagined everything into existence is strengthened.
But it can’t be confirmed unless scientists establish that the so-called big bounce does not happen. If cosmologists show that the universe is in fact a one time non-repeatable event, then the case for a universe-generating conscious-life will be compelling if for no other reason than that the odds against a spontaneous one-time creation of a universe with unique and unlikely parameters are infinite.
Sean M. Carroll, Cosmologist, California Institute of Technology, born October 5, 1966.
One cosmologist who has gone on record against the possibility of a big-bounce scenario is Sean Carroll of Caltech. He has said that there is enough dark energy to drive an infinite expansion of our universe into a kind of entropic death.
His assertion, if proven true, seems to strengthen the argument for proto-conscious-life except that he also said that the whole of reality is probably a multi-verse populated by the births of trillions upon trillions of Big Bang events — which weakens the argument.
It seems that a definitive answer to the question of whether we live in a multi-verse (or not) might be a key indicator for or against the presence of a fundamental and foundational consciousness in nature.
Paul J. Steinhardt of Princeton University; born December 25, 1952.
In 2013 a new theory was proposed that argues against a multiverse. It was proposed by Paul Steinhardt, the Albert Einstein Professor of Science at Princeton University. His team’s idea is based on data gathered by the state-of-the-art Planck Satellite launched in 2003 to map the infrared cosmic background radiation.
The theory is ekpyrotic, or cyclic, and asserts that the universe beats like a heart, expanding and contracting in cycles with each cycle lasting perhaps a trillion years and repeating on and on forever.
Steinhardt was once a major advocate for the Big Bang theory and the mechanism of cosmic inflation. He had been a prominent proponent of the inevitable multi-verse that most versions of the Big Bang theory permit. He is now proposing an alternative scenario.
His latest theory has the advantage that it makes certain predictions that can be tested — unlike the mechanism of inflation required by the Big Bang theory, which can’t. In his new theory, every bounce of the universe resembles every other bounce and presumably generates similar constants, laws, and physics. If conscious-life is rare, most bounces will spawn a sterile universe.
If the idea is right, fine tuning of our universe would have to be the natural result of some underlying feature of reality not yet understood. In this model, consciousness can emerge, certainly, but is not necessarily fundamental, causative, shared, or even inevitable.
To my mind, this is the model of the universe that is the most compelling, the most incomprehensible, the most mind-blowing. Unlike all other theories, this one suggests that the universe might have no beginning and no end. It doesn’t change. It’s eternal. It beats with a familiar rhythm, the rhythm of our hearts, and it will never stop.
What is frustrating to me is that the ekpyrotic model doesn’t add insight into the question about conscious-life posed by my essay: Is consciousness a fundamental and necessary feature of physical reality?
Or is conscious life a rare accident that occurs inside a long path of infinite oscillations in a universe whose reason for being humans will never understand?
Editor’s Note:As of July 2017, studies of the cosmic background radiation have not revealed with high enough statistical precision the presence of primordial B-mode gravity waves — a discovery which, if confirmed statistically by high sigma, would undermine the ekpyrotic theory. Refinement of the search and examination of data continues. Right now, the ekpyrotic theory is hanging by a statistical thread.
Editor’s Note July 4, 2019: Another theory gathering supportive evidence is the Conformal Cyclic Cosmology model (CCC) proposed by Roger Penrose. Click the link to learn more.
I want to veer back to the previous discussion about matter and antimatter for a moment. It seems that each precipitates equally out of the energy enriched dimensional fields of spacetime so that in a smooth, un-pixilated universe matter and antimatter should self-annihilate and sum to zero. (Refer to the Billy Lee Conjecture in a prior illustration.)
A universe whose space is smooth and continuous will not self-generate anything at all from such a process. It is the geometry of a spherical bubble within a pixilated space-time fabric that forces surplus in the production of either matter or antimatter.
The choice between the two is completely determined by the size of the pixels that make up the fabric of spacetime because pixilation of spacetime forces the normally irrational ratio of the surface area of a sphere to its diameter to collapse to a rational number, which necessarily warps the symmetry of the sphere. If matter is generated inside multi-dimensional bubbles, any reduction to rationality that compels symmetries to fail will force an excessive production of one of the two possible states of matter. It can’t be any other way.
Some physicists believe matter (and its equivalent, energy) is pixilated at the scale of the Planck constant, at least in this universe. Experiments are underway to find out if this idea is true. For now, scientists observe mathematical evidence for mysterious particles coming into and out of existence everywhere all the time. And it is matter particles which seem to completely dominate anti-matter.
To counterbalance this preponderance of positive matter, negative energy must emerge, which scientists like Isaac Newton called gravity.
Einstein showed that matter and energy are equivalent; they are two sides of the same coin. He treated gravitational energy as a deformation by mass in a mathematical fabric he referred to as spacetime. Massless phenomenon like photons of light held energy by means of their electro-magnetic field frequencies.
No one understands why quantum fluctuations occur. Some think it’s an illusion driven by the mathematics of quantum mechanics. Others think it’s real.
We know that this phenomenon of spontaneous creation of positive matter (or frequency) and negative energy is occurring, because conscious minds (scientists) observe its effects in their laboratories. No one understands the mechanism of quantum fluctuations enough to rule out the possibility, it seems to me, that our own minds — in collusion with the instruments we have invented and built — somehow create the impression — a kind of illusion, really — of phenomena that can occur only in the presence of a conscious mind.
Is it possible, for example, that inside the European Organization for Nuclear Research (CERN), scientists are creating the particles they want to see in order to confirm their parochial notions of the universe? They sometimes seem to be using their conscious minds and the machines they have designed to fabricate new worlds so remote and so tiny that they will never be observed, not by any human, not even by themselves, except in their imaginations as they read through publications of the results of their experiments in science journals.
Atlas ”particle” detector at CERN. Notice tiny human worker at lower center for scale.
Are theses scientists creating particles in worlds that lie deep within the subterranean matrix of exotic materials and forces they have built and modeled within their labyrinth of super-computers — which exist only in their imaginations, but which they are able to confirm by employing thousands of researchers around the world to pour over hundreds-of-thousands of pages of machine and sensor-generated gibberish, from which they glean the unlikely patterns they marvel-over in their peer-reviewed scientific publications?
Are these human beings, these scientists, in the first stages of using pure consciousness to create universes — albeit tiny ones — in the mammoth laboratories of CERN?
Maybe not. It seems preposterous. But it is a conspiratorial perspective I couldn’t resist including in my essay. Sorry.
Sean Carroll, in his book about CERN, The Particle at the End of the Universe, describes in chapter-six subsections — Information Overload and Sharing Data — that the data-handling and sampling processes used at CERN could enable just such self-fulfilling validations to occur absent careful and conscientious oversight.
There may be another reason why experiments always seem to confirm the Standard Model of quantum physics and never contradict it. A strange symbiosis between the standard model of sub-atomic reality — as measured by synchrotrons, accelerators, colliders, etc. — and mathematics may actually exist in nature.
If true, no one need despair that gathering resources to build larger colliders and other instruments is not practical. Theoretical physicists can simply do math to discover new truths. They can trust — should an experiment ever be completed in some unimaginably resource-rich future — that their math-based conjectures will be confirmed in the same way as was the Higgs boson.
Nima Arkani-Hamed, American theoretical physicist; born April 5, 1972.
Absent larger colliders, the path forward, according to theoretical physicist Nima Arkani-Hamed, is to keep the work of discovery inside the experimental constraints imposed by the knowledge already gathered, as theoreticians labor to develop new theories.
These constraints are already so restrictive and so reduce the number of paths to truth that it’s possible someone might find a route to understanding which is unique, sufficient and exclusive. If so, theorists could have confidence in the new theories though experimental verification might lie beyond any foreseeable technology of the future.
Anyway, the universe shouldn’t exist, it seems, except that people can imagine — under the influence of the uncertainty in the remote decimal place described earlier — that tiny differences in the ratio of matter to antimatter which emerged in the ancient past created an imbalance — temporarily, perhaps, but continuing for billions of years — which piled up to become enormous. As matter continued to pile up, so did the negative forces like gravity, which counterbalanced it.
One day, gravity (and perhaps other forces like the mysterious and long sought-for dark energy) might pull all the positive matter back into a little pile; pull it back behind the event-horizon of what Stephen Hawking calls a black-hole; pull it back into the unfathomable uncertainties of a blinking and unstable quantum singularity aching to explode.
Explode into what? Perhaps the next quantum eruption will spiral out into a new and completely strange universe of different-valued fundamental constants and a bizarre number of dimensions — a universe almost certainly unsuitable, this time around, for life.
Is it possible that such a process — driven by tiny uncertainties (or tolerances) in the natural quantum ratio of matter to antimatter within a rare configuration of fundamental constants and numbers of dimensions — could give rise to not just any universe but to one with an emergent conscious life as well?
Stephen Hawking has speculated that it can, but cautions that the odds against life are huge. He has speculated that an infinite number of universes — a multi-verse — is required to get a reasonable chance that a universe as unique and unusual as ours will appear.
Some believe the large scale structure of the universe resembles a collection of neurons, much like a human brain.
Modern science agrees with Hawking and has decided that this universe — the one we live in now — is probably only one of an infinite number of universes that make a multiverse. Our unique and unusual universe has, over billions of years, fabricated a transient conscious life which is, at this very moment, observing it.
A fleeting conscious life is discovering that the universe hovers in a state which from a matter/antimatter perspective could — if a preponderance of antimatter were produced (perhaps in an adjacent universe, if not this one — sum to zero someday like a popping soap bubble and cease to exist. When the observing conscious life is extinguished during this possible zero-sum resolution in the distant future, the result will be no universe, no life, no memory, nothing.
In any event, if antimatter doesn’t annihilate the universe, entropy might. (Entropy is the natural process of heat death, where all motion and information decay to zero over time.) Under this scenario, when the end comes, in the far distant future, it will be said (were there anyone around who could say it): the universe never happened. It will become a vanishing blip on the screen of reality, because no one will remain to remember it.
Then again, the negative forces of gravity and dark energy might restore the zero balance required by quantum non-existence to pull together all positive matter into an uncertain quantum singularity called the Big Crunch. A new universe with new parameters and constants might then emerge after the singularity undergoes a quantum fluctuation.
Maybe the universe cycles endlessly, contracting and expanding like a beating heart, which some have characterized as aBig Bounce. During some expansions conscious-life emerges; in most others, though, it does not.
Another theory of a possible catastrophic scenario has recently emerged after scientists determined the mass of the Higgs ”particle” at CERN in March, 2013. It turns out its value might permit the Higgs field to someday (no one knows when) undergo a spontaneous phase transition.
A phase transition would change the value of many of the fine-tuned constants and forces that shape the chemistry and biology of the cosmos. A phase transition in the Higgs field would certainly be catastrophic for life. It would be as if the universe was a block of ice for billions of years and in one short spasm turned to steam.
In any event, a Higgs field phase-transition would obliterate all knowledge of the universe. All history of the existence of a missing universe from the recent (or ancient) past would be lost — unable to be reconstructed, detected or proved. The universe didn’t exist; it never existed. In fact, it could not have existed.
One dynamic that no one talks about is a mass of parallel universes stacked like pancakes on all sides of our own. The mass that lies outside our own universe might be dense enough to transmit a gravitational tug that is pulling our universe apart like an expanding soap bubble in a field of foam.
This external mass might drive an expansion that provides the energy that forces galaxies to rotate at their far reaches faster than physicists think they should. Mass outside our universe could transform the metrics of our own space-time to initiate someday the phase transformation in the Higgs field that would follow a runaway expansion — an expansion that ends in nothingness, like a soap bubble popping on a grand scale.
The consequence of zero-sum, under which matter and antimatter, like popping soap bubbles, add to nothing;
or entropy, where all the material and information in the universe decline and decay by cooling and freezing to a motionless absolute zero;
or the big crunch, where negative forces pull positive matter into a quantum singularity which fluctuates into one of an almost infinite number of new realities;
or an endlessly repeating big bounce, where the universe contracts and expands like a beating heart that is driven by a set of fundamental constants that never really change — though the history of every bounce is erased by the bounce that follows;
or an inevitable phase transition in the Higgs field which vaporizes the cosmos into a state of virtual non-existence…
…means, logically, and in the perfect hindsight of an imaginary observer billions (or, perhaps, trillions) of years from now, that the probability there ever was a universe of matter populated by conscious-life might actually be zero.
A long time from now, the universe may disappear, either from the natural process of entropy, or an increase in the generation of antimatter, or both. Then again, it could morph into something unrecognizable and hostile to life through the mechanism of the Big Crunch. It might endlessly regenerate copies of itself through a cycle called the BigBounce where conscious-life almost never develops. Another possibility: a spontaneous Higgs Field phase transition, which vaporizes the universe where we live, perhaps driven by forces that live outside in a field of universes we will never see.
Yes, scientists say, under every scenario they can imagine, the universe in which humans now live will cease to exist. Conscious-life will disappear. No one will be left to argue about it. All the evidence will point to a universe that never happened.
Of course, no one will hear the evidence. In the universe that doesn’t exist, and even in an existing universe where conscious-life cannot or does not emerge, there is no reality, there is no evidence, no information, no history.
EDITORS NOTE: July 4, 2019:Based on the recent theory by Roger Penrose it may not necessarily be science-fiction to imagine that intelligent life might communicate across successive universes using the cosmic background radiation as a kind of writing tablet. As crazy as the idea sounds, evidence gathered by recent satellites is making a statistical case for Conformal Cyclic Cosmology.
These views, as I understand them, reflect the most popular ideas in modern science about the universe and conscious-life. They make sense. But these views reek with futility and despair. And, despite sensibility, they fail to answer a basic question: how can this be?
This graphic shows what scientists think happened, not why or how.
How is it that random fluctuations in the aether (for lack of a better term) generated something on the scale and immensity of a universe; perhaps an infinity of universes; and gave birth to conscious life?
The mere existence of a universe (and its conscious life) emanating from uncertain and random fluctuations in the vast nothingness of nothing seems ludicrous on its face. We can’t make sense of it; not in any way that permits us to exhale, throw out our arms and say, ahhhh… so that’s how it works.
We are missing a piece of the puzzle. It seems that modern science has led us into a tunnel that has no light at its end.
Like the radiation that stimulates our brains to create the brilliant colors we see inside our heads, consciousness may pour into us from out there.
What is anyone to make of all this? On the one hand, there is a consensus among contemporary scientists who believe consciousness results from the way brains are hard-wired. Throw in enough parallel electrical circuits to reach a threshold, add in sufficient hormonal feedback loops, and, voila! — consciousness. One problem, though: no one has done it; not yet.
On the other hand, we hear the echoes of the voice of one of the fathers of quantum physics, Erwin Schrödinger, calling from the shadows of recent history. He says, No! Brains are detectors, imbibers, of a consciousness that lives outside ourselves and is, in fact, a fundamental and foundational feature of reality. Like the mysterious electromagnetic radiation that pours into our skulls to excite our brains into conjuring up the brilliant colors we see inside our heads, consciousness pours into us from out there.
Like the unseen and as yet undiscovered dark matter and dark energy that many scientists believe together shape the universe and drive its expansion, consciousness remains elusive of attempts to discover it. Perhaps scientists aren’t looking hard enough or in the right places.
Then again, maybe dark matter doesn’t exist and will never be found, if alternative theories like MoND (modified Newtonian dynamics) prove true. It might be that the shape of galaxies and the accelerating expansion of space are instead the evidence of parallel universes that stack like pancakes against our own universe to add the elusive gravitational forces necessary to both constrain the galaxies and drive the expansion of space. Who knows?
It might be that MoND and the gravitational tug of parallel universes work together to produce the odd cosmology astronomers are observing with today’s modern space sensors. Constructing a successful model of the universe which incorporates the reasonable conjectures of MoND might depend on a collaborative summation of forces that occur both inside and outside of our own universe.
What the universe is and how it really works is not yet understood by the scientists who line up for funding before governments and universities; not even close.
What if life-forms are connected in some way to a Conscious-Life who brought the physical universe into existence?
In any event, under the stimulation of consciousness, all seem to know on some level deep inside that they are alive and aware and connected, somehow. They feel a certain common awe when they look up into the night sky and see the universe that birthed them; folks seem to sense a Conscious-Life who stands behind it all; who knows and cares about them; who shares with them the glorious experience of the universe. It’s the religious experience that every culture on the earth has in common.
What if this experience is real? What if we are connected in some way to a fundamental and eternal Conscious-Life who brought the physical universe we know into existence, perhaps through pure thought like we imagined earlier the scientists at CERN might be learning to do?
Is this a question worth exploring?
Does consciousness come first or last?
Is an answer within our grasp that will satisfy our yearning for truth and certainty? Or is it a dispute that will never be settled?
Tobias Dantzig, the Latvian author of Number (one ofAlbert Einstein’s favorite books), once claimed, …from the standpoint of logic either hypothesis is tenable, and from the standpoint of experience neither is demonstrable.
Can he be right? Will the arguments between hard-headed scientists and stubborn philosophers last forever?
I don’t think so. Scoffers may say no, the dispute is already settled. Schrödinger was wrong. And if he wasn’t wrong, could anyone detect the difference? Does it matter at all if consciousness lives inside our heads, or if brains draw consciousness from the universe outside?
I believe the issue can be settled. And it is important. The stakes for humans are enormous. In religion, philosophy, politics, and government what people do, the way they live, their planning for the future; the ways they choose to live out their lives and organize their societies, humans seem to be grounding every decision, every action, every moral choice they make on an assumption that each person creates inside themselves a unique view of reality, which will die when they do.
But what if they are wrong?
What if we learned that consciousness doesn’t die?
What if we learned that, though our bodies may someday die, consciousness never dies; the feature of our existence which imparted the sensation of awareness was something our bodies fed on during their brief lives to give them meaning?
What if our kids and grandkids, our friends and neighbors, even our enemies, and all those that came before us and will someday come after us imbibe alike from this same life-enhancing pool of awareness?
What if all life-forms, sufficiently developed, drink from an ocean of Conscious-Life everywhere in the universe?
What if we learn it isn’t our bodies that make us feel alive?
It is instead a fundamental and basic feature of the universe, a sea of consciousness from which we all drink while our bodies live.
What are the consequences should we learn that, though our bodies and brains may decay to dust,the awareness that makes us feel alive never does?
What if we learn we are conscious-life and always will be?

Addendum by the Editorial Board, 16 September 2018: Michael Egnor is not a public person; his biography on Wikipedia is hopelessly incomplete. Nevertheless, he has performed a number of neurosurgeries, apparently, where outcomes ran counter to popular theories about how the brain and consciousness work.
On September 14 Michael Egnor published in Christianity Today a non-scientific article where he wrote about his clinical experience. Billy Lee strongly argued against publishing a link to his article, but The Editorial Board, unanimously overruled.
Seen through the prism of Billy Lee’s essay, we agree that the article contains clues that readers might find helpful despite the surgeon’s biases — one or two of which Billy Lee might characterize as kind of silly. Here is the link: More Than Material Minds. The Editors
times larger. A factor of 1.414… won’t change the argument. It strengthens the point but is, in the end, not important enough to include in an article that is already overly long. Curious readers can review the reasoning in my essay 
. Energy and massless particles like photons of light are equivalent based on their frequencies; Einstein included this feature in his less familiar but expanded equation 
. These equivalencies are clues that might enable someone to properly explain how the universe works on large scales and small.
