12 ASSERTIONS

I have hope that someday readers will visit Quora.com to look up meBilly Lee — to read my answers to hundreds — perhaps one day thousands — of questions asked by every kind of curious person from every part of the world.

I love to read and think about questions from unmet others — to encounter oddities that have never occurred to me to ask or answer.

It’s humbling to be confronted by the knowledge that not only do I not know the answers to thousands of questions, but I lack the breadth of mind to even imagine such questions; I am convicted by my own lack of curiosity and inability to think deeply about an almost infinite number of mysteries that other people of all types and backgrounds wonder about and seek to understand.

Hundreds of years ago, polymaths — the smartest and most energetic of them, anyway — could know and understand all that humankind ever dreamed. Today, the world is too complex; the depth of knowledge required to understand a narrow subject — like juice-carton safety-caps (I hold a patent) — takes years, maybe decades, to acquire.

Is it any wonder that smart people give up and go stupid?

No matter how much a Doctor of Philosophy knows about the rules of logic, he’s a dummy to every certified automobile mechanic he will ever meet — and vice-versa, right?

A way out of the dilemma is to practice the art of pontification. I pontificate based on a lifetime of experience; and reading; and wandering the world; and poking around in my backyard — to ponder why things are the way they seem to be.

Je connais beaucoup de merde, and I know a lot of nothing. When I write it down, well, magic happens. Resonate rings of truth rise which when later read render me reeling.

I’m unsure where-from the magic comes. It seems to fall from heaven to light the world. I’m driven to share with souls known only to God, because I have no way to know who reads my blog. I know only that some folks make the time, because WordPress stats say it’s so.

One of the things on Quora.com that seems to confuse a lot of people is the difference between momentum — a measure of the mass of an object multiplied by its velocity in a particular direction — and kinetic energy, which is a measure of the energy of an object that has been accelerated for a period of time in a particular direction, which enables it to do work.

Momentum is an object’s mass times its velocity; it is a measure of its inertia along a defined direction. It is measured in newton-seconds.

Kinetic energy is released by an object in units of acceleration that were initially induced by newtons of force. It is equal to half the quantity that is calculated by multiplying an object’s mass by its velocity squared. It is measured in units called joules, which are newton-meters.

Of course, spinning objects that aren’t moving in any direction have momentum and kinetic energy, too. The two are wrapped together in a concept called, torque.

Dear God, help me.

Now, I’m confused. Somebody, please, explain to me. I thought I understood until I started writing.  I did.  Really.

Another source of confusion concerns the nature of photons, which are tiny packets of oscillating electric and magnetic energy — from which light is made, right?

Photons seem to have no mass in the vacuum of space. When they pass through a material like glass, they leave a wake of disrupted electrons in the glass which belch out polaritons. These particles add mass to the photons and slow them down by as much as forty percent.

Polaritons can be described as light-matter waves

Does anyone believe it?

It’s God’s honest truth.

When photons exit the glass and enter the vacuum of space they leave the polaritons behind, lose their acquired mass, and jump to light speed, instantaneously.

Who knows for sure that it’s true?

Who understands why?

Here is an interesting thought:  if humans — limited in understanding by language and mathematics  — are unable to ever know why photons exist and behave as they appear to do, then who can? Who does understand?

Is all the complexity of the universe understood by no one? Is it possible that an unlikely universe can exist forever whose fundamentals cannot be articulated and which lies outside the experience and ability to comprehend of any sentient life-form whatever, whenever, wherever?

What kind of place do we live in, anyway?

Calm down. Take a breath.

Reality may not be as hopelessly inaccessible as it seems. Can it?

Here are some questions, which I’ve answered as truthfully as I know how. The answers are assertions of truth.


1 – How did a single cell organism eventually lead to complex life on earth, and does that mean that all life has a common ancestor (the single cell)?

This one is the 64-million-dollar question that no one has ever answered convincingly. Prokaryotic cells were established 3.5 billion years ago on the early Earth. They evolved to become the bacteria and archaea branches in the tree of life that exist to this day.

Here is the amazing part, at least for me:  Eukaryotic cells, which are the much larger and more tightly organized cells of all animals and plants, did not emerge until two billion years after prokaryotes. It took a long time to evolve cells capable of conjugating into more complex life.

For the past 1.5 billion years eukaryotic cells have evolved into life forms capable of civilization and space exploration. The time frame is amazingly long.

The thought that a lunatic could in a moment of bad judgment start a cascade of events that extinguishes all life is troubling.

When astronomers look into space they see no signatures of life as advanced as ours. Again, this is troubling, because it might be an indicator that the knowledge possessed by advanced life-forms may approach some asymptotic limit where self-annihilation becomes inevitable.

2 -What evidence would falsify the theory of evolution?

No one knows all the myriad ways that life evolves, only that it does. That life evolved from cells that were fully functional 3.5 billion years ago is an established fact, because of evidence found in rocks.

Scientists know that it took two billion years for these ancient cells to evolve into the much larger and more tightly organized eukaryotic cells that today are the foundational structures of all animals and plants.

No one knows how life as complex as cells was established on a hostile planet like the early Earth, but everyone has an opinion; these opinions are called conjectures and theories.

One scientist might say that life started on Mars and was transferred to Earth on space debris uplifted by a cataclysm on Mars. Another says no; all the stuff necessary to make prokaryotic (primitive) cells existed in abundance on a young Earth — perhaps near hot vents in the ocean floor. Other geologists say the earth was bone dry at one billion years. Oceans came later, so just what the heck does anyone know for sure, anyway?

Many conjectures purport to explain how life changed from unicellular eukaryotic forms 1.5 billion years ago into the space-exploring civilizations of today. Every conjecture thus far has already been falsified either by evidence or by competing conjectures that make as much sense but are different.

For example: some say mutations in DNA drive evolution. The problem is that mutations are too rare. Some say an eco-sphere of processes driven by a halo of molecules that cling to DNA drives evolution. They call it epigenetics. Others say, no. RNA drives evolution like colonies of intelligent ants who build hives. There are other explanations.



None are verifiable or generally accepted due to an insufficient body of proof that is able to overcome alternative ideas that are equally compelling.

Another problem is that no one knows if DNA life is all there is. DNA is a molecule that cannot be seen or worked with until it is amplified into a viewable goo.

Are there other undiscovered molecules no one knows how to amplify?

Understanding of the parameters and limits of life is incomplete and may perhaps mislead researchers. Humans might not yet know enough to figure out the dynamics of genomes. More needs to be discovered and understood.

Is there a shadow biosphere that is in a symbiotic relationship with DNA? Where is the dark DNA that biologists can’t find that is necessary to code for many of the proteins they know exist?

How were cells themselves established so quickly on Earth? It’s a question whose answer is discussed by countless experts and non-experts; no answer fully satisfies.

Darwin’s ideas about natural selection and survival of the fittest have their place. But he was just getting started, and he died a long time ago. Scientists have a lot of work left to do.

3 – Which Bible story is most objectionable when looked at in the context of modern morality?

All Scripture is God-breathed. To love and be loved by both God and people is why we were born; it’s what makes life precious and worth living. No one wants to die; no one wants to be hated.

The sad part is that everyone suffers; everyone is hated by someone; everyone hates someone; everyone dies after a life of blunders and sin. Christ Jesus came to save the lost, which by the looks of this thread is pretty much everyone.

We have hope. It’s something to hold onto as we grow weak and find ourselves ruined at the end of our minutes in the sun on our beloved Earth.

Jesus made a path for us. It cost him everything a human can pay. He somehow survived the Roman crucifixion that killed him to show the poor and overly burdened that in his power is the way, the truth, and the life.

There is a path to paradise; we — everyone of us — can find it by surrendering to the God who loved us, gave us life, and suffered to set right what we put wrong.

4 – People say Newton’s third law, “For every action, there is an equal and opposite reaction,” is not accurate. Is it true?

Einstein said that only mass and energy exist; they are in fact equivalent; they are the same thing; two sides of the same coin. Energy gives rise to all other phenomenon and forces that scientists observe.

Stephen Hawking said that when mass (or energy) comes into existence a negative energy must emerge to balance it so that when added up everything in the universe sums to zero. It appears that Newton’s third law, equal and opposite, is not only accurate — it is a fundamental balancing principle that undergirds existence.

Mass is matter, which can be positive or negative and is referred to as matter or anti-matter.

The Billy Lee Conjecture claims that mass is pixelated (quantized) such that in the contest of emergence within the smallest spherical volume, matter or anti-matter (one or the other) will prevail due to a natural truncation of π in the putative spherical volume of the creation space.

An evenly divided ratio of matter and anti-matter within a spherical creation-space is physically impossible if π is truncated by pixelization. Matter and anti-matter will annihilate until a single piece of either matter or anti-matter remains after the creation event.

To maintain a zero-sum, balancing counter-energy will emerge according to speculation by the late Stephen Hawking.

Over long periods it seems that an extraordinary amount of matter has accumulated inside our own universe by surviving the natural annihilation of matter by anti-matter. This matter seems to have generated an enormous amount of counter-balancing energy — some of which Newton called gravity. Most of the energy remains undiscovered and is referred to as “dark.”

In our own universe, π seems to “round-off” near the precision of the Planck constant.

In universes outside our own — some of which seem to be pulling our universe apart in an accelerating expansion caused, perhaps, by their own gravitational forces — π may truncate to different values to generate in some cases a prevailing anti-matter and opposing energies that manifest qualities different from the energies found in our own universe.

If parallel universes disrupt the zero-sum strategy of our own, it may still be true that the principle of zero-sum or equal but opposite is operational, but humans are too small and the distances are too far for anyone to ever know for sure that it is true.

5 – What are the major foreign policy issues that the United States of America is working on in 2018?

I’m writing this answer just after the meeting in Singapore between North Korea and the United States involving the Korean nuclear arsenal.

The Secretary of State, Pompeo, said yesterday that NK has two years to de-nuke. This delay might tempt the Japanese to convert their stockpile of 47 tons of plutonium into bombs. Japan and North Korea have issues related to the Japanese occupation of Korea from 1910 to 1945.

It takes ten pounds to make one bomb. The Japanese can make as many bombs as they want in as little as 24 hours.

A Japan armed with 10,000 nuclear bombs (they already have the missiles to launch them) is a clear and present danger to China, Russia, and Korea — not to mention the United States with whom Japan has a beef that goes all the way back to World War Two when the USA destroyed 67 of their cities with napalm; two cities by atomic bombs.

The USA has occupied Japan ever since. Some of the Japanese probably hate us — who knows for sure?

6 – Can a photon’s speed be slowed down? I have heard that it can be slowed by a medium, but I have also heard that it is just the velocity being slowed as it “bounces” from particle to particle? I am not talking about Bose-Einstein condensation.

The current thinking is this: when a photon leaves the vacuum to enter a material object, it leaves a wake in its path that vibrates electrons in the medium. These oscillating (or disturbed) electrons generate polaritons, which are photon-like objects that can catch and add mass to the photon. With mass added, the photon slows down — as much as 40% in glass, for example, which enables more polaritons to pile on.

When the photon exits into the vacuum of space, it disentangles from the polaritons, and instantly resumes light speed.

I didn’t make this up.

It’s what some physicists are saying, and it explains a lot and leaves a lot unexplained — like all things physics when folks go just a little deeper into the abyss of understanding.



7 – What is the relation between light and darkness? Can one exist without the other?

Light is the action of certain wavelengths of electromagnetic radiation on structures in the eye, which trigger hallucinations in the brain that humans report as “light.”

An infinite range of frequencies are “out there.” Humans are blind to almost all of them. People who are unable to trigger hallucinations induced by electromagnetic radiation say that they are experiencing “darkness.”

Some frequencies of light are experienced as “heat.” Because the sensation is not accompanied by visual cues, people in hot rooms with no windows believe they are experiencing “darkness.”

The experience of heat is caused by the same electromagnetic waves that induce visual experience, but they are a tiny bit longer in length than those which induce the experience of the color “red” in humans.

The longer waves carry less energy and are invisible to people unless they view the ”infra-red” light through high-tech sensors. Local fire-departments use these sensors to identify ”hotspots” where fires might reignite.

WHY SOMETHING, NOT NOTHING?


8 – Given an opportunity to pass through one or two slits with no detection, will a quantum object always pass through both?

If the slits are in the right position and are cut to the right size and are at the right distance from the source, a pattern on a detector screen will evolve over time to look as if waves are passing through the slits and interfering in a predictable way with each other.

Of course, it’s not true, because the particles are shot one at a time and the duration of the experiment can be hours to weeks long. The shots land one dot at a time. After thousands of shots, a pattern that resembles what one would expect of waves interfering is formed by the particles as they accumulate on the detector backstop.

No one knows why. The phenomenon is inexplicable.

9 – Is Jesus a hoax? Jesus has not walked on Earth in 2,000 years. How can a man 2,000 years ago save anyone?

I was hungry and you gave me something to eat, I was thirsty and you gave me something to drink, I was a stranger and you invited me in,
I needed clothes and you clothed me, I was sick and you looked after me, I was in prison and you came to visit me.

The righteous will say, ‘Lord when did we do these things?’

My answer will be, ‘Everything you did to help suffering people, you did for me.’

The preceding is a paraphrase of part of Matthew 25, a book in the Bible.

Read it. Why not?

The answer is in the sense that it is not a hoax that the “least of these” walk the earth when we do. How we treat unfortunates is, in the view of Jesus, the way we treat him. He will return to us the same courtesies when finally we give GOD an account of our lives.

10 – Can RNA or DNA think?

RNA, in its many forms, behaves like ant colonies which swarm over the DNA pile to do a number of tasks that seem to involve a lot of decision making.

RNA selects out of billions of bases a few thousand which it strings together to make “genes” that it transfers to ribosomes — which are made almost entirely of RNA and are among the oldest structures in cells.

At a ribosome, the genes are coupled to RNA that carries amino acids; the amino acids are then ejected from the ribosome to be strung together like necklace beads; they are transported to Golgi structures where they are folded into proteins.

A process this complex — and it’s actually far more complex than this summary implies — can be orchestrated without intelligence; it’s possible, but without intelligence of some form, the process seems, at least to me, to border on the miraculous.

After all, what is the result?

It is a conscious thinking life-form who can, in cooperation with others, figure out its own origins.

It’s amazing, right?

11 – How do Quantum spins get affected by Quantum entanglement?

All atoms with electron shells that are home to more than one electron have entangled electrons. The spins tend to oppose each other. With bosonic particles, down conversion techniques produce photons that have opposite polarization.



Most physicists think that spin is induced during measurement; the spin is transmitted oppositely to the entangled partner instantly — no matter how far separated.

For this reason, a pair of entangled particles can be envisioned as a single particle that behaves as if one of its dimensions (the distance between its endpoints) is missing.

The distance between the entangled pair behaves as if it is zero — when it is known to be non-zero.

12 – What is the viability of colonies on other planets?

The two planets closest to Earth are the most viable places for colonies simply because they are the easiest to resupply. They are Mars and Venus.

Neither can sustain colonies, because they lack magnetospheres, which are essential for deflecting high energy particles emitted by the Sun (called the solar wind). These particles are deadly to life. The molten iron-nickel cores of Mars and Venus froze millions of years ago on both planets, which collapsed their magnetospheres.

Venus has a highly toxic atmosphere, which is another reason to rule out colonization there.

Beyond Mars are gas giants. Only their rocky moons are candidates for human colonies. All the moons appear to be too cold to operate the machinery necessary to sustain human life. Most lack protection from the solar wind.

FINDING LIFE IN THE UNIVERSE


Bonus Assertion – Does a photon consist of (f) quantized energy packets each of (h) joules?

A photon seems to be a packet of vibrating electric and magnetic energy, each part of which exerts its energy at a right angle to the other. The energy in the packet is proportional to vibrational frequency alone. A photon has no mass or acceleration. It travels along at a constant speed in space-time. The electric portion of the energy is about seven times the energy of the magnetic portion.

Photons can become more intense (that is, brighter) when they pile up. Pile ups don’t happen to electrons, protons, and neutrons because they obey an exclusion principle that forbids them from occupying the same space at the same time.

Photons can pile up, but their intensity (or energy) can only be transferred into electrons that are in an energy state that resonates with the frequency of the incoming photons. Non-resonate electrons ignore un-matched photons, so photons pass through non-resonate electrons unimpeded.

The energy of an individual photon can be expressed as its kinetic energy and  shown to equal Planck’s constant times the photon’s frequency, which always results in a very small number.

When expressed in terms of its wavelength (λ), photon energy equals the Planck constant (h) times the speed of light (c) divided by the wavelength (λ) of the photon. Notice that the mass term is missing due to a simple manipulation of the relevant equations — which anyone who is interested can find in the following link.

PHOTON

Momentum might not be an appropriate metric for a force carrying boson like a photon, because momentum is based on mass, which many physicists say photons in a vacuum don’t possess.

Another reason momentum could be an inappropriate metric is that the velocity of photons in a vacuum is independent of any reference frame, right? Momentum is a vector quantity that is always measured in relationship to a particular reference frame or the momentum of another particle.

There is a theory that claims that photons pick up mass when they pass through materials like glass. They seem to leave a wake that shakes up electrons in the material. The vibrating electrons release polaritons, which by a mechanism analogous to superposition add mass to the photon and slow it down. When the photon exits and returns to vacuum, it sheds the polaritons, becomes massless, and returns to light speed instantly.

Perhaps photons in the vacuum of space acquire mass by interacting with virtual particles that emit virtual polaritons.  Notions about the nature of the universe would be changed radically if such a notion were confirmed by evidence.

Because h and c are constants, they can be multiplied together to give a constant that is very close to 2E-25. Dividing 2E-25 by the wavelength of a photon will give its energy in joules. Of course, all units are SI, which stands for standard international units, correct?

Since E = hf or (hc / λ) , the energy is always a multiple of h, which is the Planck constant. The word “multiple” is a simple way to say “quantized”.

So, the energy of a photon bunch or pile can be expressed as a multiple of the number of photons of a certain wavelength in that bunch. The energy in each individual photon is its wavelength (or frequency, if you like) multiplied by the Planck number — a constant equal to 6.626E-34.

It takes a pile-up — or bunch — of about 7 photons with wavelengths close to 2.5 one-hundred-thousandths of an inch long (635 nanometers) to carry enough energy to light up the sensors in a human eye.

How much energy is in those seven photons? It is seven times 2E-25 / 635E-9 —  in joules, right?

It’s 2.2E-18 joules. Converted to an easier metric befitting its scale, the energy is nearly 14 electron volts, which is equivalent to the energy held in 14 electrons.

People say that photons with wavelengths that measure 635 nanometers create the color yellow-orange in their minds.

Q & A BY THE BOOK

All writers know the column, By the Book, published every Sunday in the New York Times Book Review section.  Each week the editors pick a popular writer and ask him or her a fairly standard set of questions that would be impossible for normal people to answer off the top of their heads.

The authors rattle off the names of all kinds of titles and writers and say smart things designed to dazzle the little people who are always starved for an entertaining read.

I’m a pontificator who has never sold a book and never will, most likely. Authors sell their souls to write for money; they do exhausting tours where they answer stupid questions asked by stupid people day after stupid day. From these gatherings of stupidity they hope to sell a few books. It’s stupid.

Through books and other media, the public is exposed to a version of truth filtered by the most powerful people on Earth — to paraphrase Pulitzer Prize winner, Ronan Farrow.

Yes, it’s sickening. People are reading crap; they are immersed literarily in fibs and fabrications, which are shaped to make the world seem less evil, more friendly.

The truth that no wants to hear — I’m screaming it from cell towers to swarming people who seem to lack ears — billionaires have enslaved us. We are living in a gilded prison.

Totalitarianism has already won — not through governments but by supremely advantaged individuals who have no limits on the money they can make and keep — no limits on their power or their reach.

It’s true.

The rest of this essay is a parody of By the Book. The imagined interviewee is Billy Lee, the Pontificator. That’s me.


Billy Lee, the Pontificator

What books are on your nightstand?

I honestly don’t know. Can you give me a minute to run upstairs and look on the floor and my wife’s dresser? I keep current reads close to bed where I do most of my reading. It won’t take long… …

Ok. Thanks for waiting.

“The Periodic Table in Minutes,” by Dan Green; “Genetics in Minutes,” by Tom Jackson; “The Making of the Atomic Bomb,” by Richard Rhodes.

What kind of reader were you as a child? Any favorites?

“The Poky Little Puppy,” by Janette Sebring Lowrey and Gustaf Tenggren was my all time favorite. Mother read it hundreds of times.

I remember being amazed to learn that anyone can dig a hole under a fence to open a world of naughty possibilities. It cost a serving of strawberry shortcake to get caught; it seemed worth it to my little mind.

Your nightstand doesn’t seem to include fiction.  What genres do you avoid and which are you drawn to?

I’ve read a lot of good fiction, but most are classics like “War and Peace” by Leo Tolstoy and “Crime and Punishment” by Fyodor Dostoevsky. I would say that Fyodor ruined my interest in fiction. His book was a nightmare that threw me into depression.

War and Peace was different; it taught me how the world works; Leo laid bare the fallacy of the great man theory of history.

But yes, I avoid fiction. As a teenager I read “Atlas Shrugged” by Ayn Rand a couple times. The book ruined my life more than any other work of fiction, because it claimed to be truth. Living life proved it wrong, but its view of the nature of humans derailed me for decades.

I am drawn to books about science and math. Enough said, I hope.

I enjoy history.

“Retribution” by Max Hastings is a block buster about World War II — as is “Devil’s Voyage” by Jack L. Chalker.  “This Kind of War” by T. R. Ferenbach is a history of the Korean War that knocked my socks off.

You like history. Is there any history you learned from reading that isn’t taught in school? Anything you learned that’s shocking?

During the 150 years before America became a constitutional republic, two-thirds of all white people immigrated as slaves, who in those former times were called indentured servants. Amazing, right?

They came unchained on boats voluntarily, because life was brutal in Europe for poor people. Their term of slavery lasted seven years and ended with emancipation.

Africans came in chains. They served until they became too frail to work; they were set free to die of starvation. The term used was manumission. Ten percent of African slaves were set free this way by the time America became a republic in the late 1700s.

From before the beginning, America was a slave state. The privileges of freedom were extended to white men who owned property. Only they could vote, but not for Senators. State legislators with approval from their Governors appointed Senators.

The founders enshrined slavery in the constitution. Eighty-five years after its signing, half of all Americans went to war against the other half to preserve slavery, but they lost.

After the Civil War, it took the Confederates twenty-five years to terrorize blacks back into submission. At the same time, northern whites committed a genocide against the native peoples they called redskins.

In the 1900s, slavery was renamed capitalism by industry titans to help them make a more appealing counter argument against a system that was catching fire in Europe called communism.

Communists believed wealth should be produced cooperatively and then shared. The idea of sharing was anathema to slave holders (business owners) who referred to their slaves as workers.

Owners abrogated their obligation to care for their slaves by forcing them to provide for their own food, housing, and medical care out of a tiny stipend they bestowed, which today people refer to as a minimum wage. The owners somewhat derisively called the new rules freedom.

After WWII, the wealthy created what they liked to call a middle class (which included about ten percent of the population) to reward the mostly poor farm boys who had risked their lives to protect them.

After 1980, the entitled kids and grandkids of the aristocracy began to disassemble the system their fathers and grandfathers had built, because they felt that the little people weren’t grateful enough. They called it the Reagan Revolution.

Today, leaders promise to make America great again. No more Negro presidents. No more subsidized health care. No more regulations to protect the disadvantaged. Everyone will stand on their own two feet or perish.

It’s the way it’s always been. The escape to America, it turned out, was an escape from freedom.

The USA is now the most merciless police state in world history. The country is demoralized by a military occupation punctuated by non-judicial executions and excessive displays of military force against civilians.

The occupation of America is undergirded by a nightmarish penal system that locks up millions in high-tech prisons where tens-of-thousands are tortured with solitary confinement.

What is the worst part? The USA is building a wall to lock people in. Soon everyone in the USA will be a prisoner unable to leave. That’s the future.

America is going to create a society that reflects the values of its billionaires and the cartel of foreign oligarchs they call friends.

Guess what? There’s nothing anyone can do about it. Take the pills they give you and pretend life is great.

Try hard to cope, and you just might.

Wow, Billy Lee. Glad you got that off your chest. If you could require the president to read one book, what would it be?

The Bible.

Does he have time? It’s close to 800,000 words —  twenty novels.  It’s a lot of reading for a man in his seventies who golfs and is known for not reading much.

Who knows how much time any of us have?  I don’t.

What book are you embarrassed not to have read yet?

Moby-Dick” by Herman Melville. I own the book and have read through the first half at least twice. It’s going to sound strange, but I honestly think the book is about homosexuality. There is a scene in one of the first chapters where two men sleep together in the bowels of a boat. They seem to have an affection for each other that, frankly, I find touching.

The title is a little suspicious. Try screaming it three times in a church without offending anyone.  Moby-Dick!  Moby-Dick!  Moby-Dick!  It’s hard. It’s a bit of a tongue-twister to boot.

You’re organizing a literary dinner party. Which of three writers, dead or alive, do you invite?

Well, first, I have to get a buy-in from my wife, Bevy Mae. Beverly isn’t going to throw a dinner party just because I say so. But assuming she agrees, I’d invite Michael Faraday, Albert Einstein, and Richard Rhodes.

All three lived on the edge of knowledge where uncertainty rages; where fear can overwhelm the unprepared. Faraday’s The Chemical History of a Candle is one of the best science books about candle flames that I’ve ever read. Einstein’s General Theory of Relativity is a joy that anyone can imbibe in a few short hours if they skip the math and physics. And Richard Rhodes proves in his tomes that any idiot can build and store thermonuclear bombs in their basement.

If you would be gracious enough to permit me a fourth invitee, it would be Che Guevara — probably the best read and most informed writer of all time according to declassified CIA assessments. John Kennedy organized the original Green Berets based on one of his books. 

Much of Che’s work is unpublished. His published work is under a suppression protocol inside the USA. Expect releases now that new leadership has risen in Cuba and the United States.

Who would you want to write your life story?

Jesus of Nazareth. People say that he never wrote anything, but he was literate and knew things most folks can only wonder about. Of all public figures past and present, Jesus seems to be the one who understood people best and loved enough to be tender. I don’t think he would humiliate me.

Paul Newman. (January 26, 1925 – September 26, 2008)

What do you plan to read next?

Something I’ve written, probably. I’m the greatest pontificator there’s ever been. Why go out for hamburger when there’s steak at home?

Paul Newman said the same when someone asked why he stayed faithful to his wife, Joanne Woodward. For those who understand what love is, no explanation is necessary.

25 QUESTIONS

A few months ago, I published 25 Answers to questions readers of Quora.com took time to ask me, because they trusted I knew what I was writing about. Yes, the world is easily fooled by pontificators posing as experts. I confess, I am one of them.

I am a bona-fide pontificator and intend to continue pontificating until I can no longer remember my name. For me, it’s art. My promise is truth, accuracy, and to fix screw-ups when someone points them out. 

The response to my blog-bag of answers was underwhelming to the point where I wondered whether I should ever inflict another anthology of eclectic curiosities on any group of readers anywhere in the world.

Yes!  I decided. Of course, I will. I love to read what I write!

When I forget what I once knew, I read the posts and remember how smart I was when I could remember stuff. It’s a good feeling. Someday I hope my grandchildren will understand why I don’t remember their names or how old they are. Someday I hope they will get what I’m talking about.

Brain-dead and happy is a wonderful combination, and I have it. Yes, I do. It is wonderful. I feel happy and content most of the time.

My mother had Alzheimer’s for years. It was a peculiar variation where she could remember twenty-five quips and jokes, which she repeated to anyone who would listen. Sometimes she wondered what was wrong with her. She asked about it, sometimes.

She always forgot the answer, but to the end she never forgot her repertoire of sure-fire laugh lines. Mom delighted us to the very end of her life, God bless her.

Anyway, I know stuff, and I’m no longer afraid to share. I would say I am becoming fearless.

This essay is a collection of 25 more questions that people from around the world have asked, and I have dared answer. My last Quora compilation was mostly math and physics. Not this time. Here answers focus more on politics, philosophy, religion, and other esotery.

Oh, I might slip a science or math question in here or there for nerds I know are out there who read my stuff and cling to every word.

Here goes.

1 – How is it “just” for jails to be privately owned in the U.S.?

Allowing private citizens to own the means-of-incarceration is as insane as it is unjust and undemocratic.

Since 1984, America has allowed people to sequester as much wealth as they can manage. The looting, cheating, and chicanery that followed has turned America into one of the most corrupt, cruel, and unfair countries the world has ever known.

The result is that now we have an associate of a powerful Russian cartel serving as our president. Are we really going to allow his friends to own our prisons?

Are we out of our minds?

The situation is far worse than you can imagine.

Billionaires run the media. You aren’t going to hear about ways of organizing our country that are in opposition to their consensus about how things should be done. What passes as “dissent” on shows like Rachel Maddow, for example, has the backing of some billionaire somewhere.

We don’t know the names of the people who run our country. They don’t run for office. They do buy the services of office holders on both sides of the aisle — GOP and Democrat. It’s disturbing, especially when people finally realize that they are at bottom mere slaves with no real power. If voting made a difference, would billionaires allow it? Would you, if you were rich? I don’t think so.
 

Even now, confidence in our electoral system is being undermined. Reality Winner, the NSA contractor who exposed Russian tampering with our election results, rots in jail; she can’t obtain bail. The media doesn’t cover her. They want us to forget all about her.

Keeping Reality incarcerated undermines confidence, because it makes it seem like the government has something to hide about our election process.

2 – What does Elon Musk think about religion?

RISK

Elon believes (correctly) that the risk of a future human extinction event approaches certainty over a very short period of time that can be estimated to be in the hundreds of years or less.

Elon believes we are in a race against catastrophe; humans are special and must be protected; one way to reduce extinction probabilities for humans is to establish populations on other planets and moons.

There are 165 or so rocky (solid) bodies in the solar system with enough gravity that humans can walk on them. Places where large populations can survive are fewer than five and could be as few as absolute zero.

Mars has special problems for human survival which must be solved. It has no protection from high energy radiation and cosmic rays. It lacks a magnetosphere and the atmospheric gases like nitrogen and oxygen that are opaque to harmful rays and particles. Elon believes these problems will be solved and that risk of extinction can be reduced if we establish vigorous colonies there.

He has hope where most informed people do not. My hope is that we can avoid extinction on Earth, but volatile climate and frequent ice ages are difficult to overcome.

We also have new and unusual risks associated with our technologies —biological, nuclear, AI, totalitarianism, resource depletion, and runaway climate change.

Natural risks include asteroid strikes, super nova irradiation, and volcanism. These natural risks are likely to be the same (or larger) on other bodies in the solar system as they are on Earth.

Two human-like species are known to have gone extinct in the geological record. (Some anthropologists say it’s three.) Human populations experienced a near extinction event 70,000 years ago when the total population collapsed to less than 4,000.

I do not know what Elon Musk thinks about organized religion.

I see religion as a brake on the tendency of humans to kill each other, which history teaches has sometimes been effective and at other times not. Sometimes, strongly held religious beliefs lead to war.

On one thing humans agree: they love to fight.

3 – What is the greatest achievement in human history?

Blaise Pascal said that civilization advanced when people finally understood that being the son of a Queen did not qualify someone to be a King.

Nepotism kills civilizations and impedes human progress. An example is the president bringing in his family to manage the United States, presumably because loyalty trumps ability.

The cascading catastrophe that is enveloping us will soon teach anyone who is teachable that placing loyalty to a “king” above the ability to serve our country is one of the many roads that leads nations to ruin.

4 – Why is there a lot of woo-woo surrounding the double slit experiment?

If you shot a BB gun once every five minutes for two weeks at a steel plate that had cut into it two quarter-inch slits, you wouldn’t expect to find 25 or so tidy columns of holes in the wall behind when you were done. People who have done this experiment with atomic scale particles always say “woo” after, because the phenomenon makes no sense. 
 
The mathematics to describe the phenomenon is the same as that used to explain wave-behavior. The problem is this: even if you shoot one wave packet at a time (using photons) instead of solid BB-like particles (like Buckyballs), no one expects that over a few weeks tidy columns will form on the back wall that look like wave interference. The reason for the pattern is a total mystery.

5 – What is the origin of geometric shapes (triangle, circle, cube, etc.)?  If the universe was governed by different laws, would it be possible that these concepts would also be different?

People speculate about the origins of idealized shapes that don’t occur in nature (except approximately). People seem to crave symmetry. They don’t like cognitive dissonance, uncertainty, or ambiguity.

People who are dissonant-intolerant are easy to manipulate. Politicians prey on people’s discomfort by offering simple solutions in return for votes. The result is always disillusionment, because nothing involving people is simple.

Nothing in nature is simple, either.

Triangles, circles, and cubes seem simple because of their symmetries. They appeal to the simple-minded among us — which is 99% of the population, right? It might be 100% if mathematics and language are insufficient to understand ultimate reality.

Einstein had this theory that only mass and energy exist. They are equivalent; they are two sides of the same coin. Space and time are a consequence, not a cause.

Space-time was described by tensor-metrics, and the metrics show that space-time does not have to be flat.

Lines can be thought of as geodesics, which are “straight” only when the metrics of space-time are “flat”. When the metrics “curve” space-time (as they do near massive objects) parallel lines might be parallel in one place only, as lines of longitude on Earth are parallel in one place only — at the equator.

The laws of physics seem unlikely, because twenty or so constants in nature have been discovered that can’t be derived and seem to make no sense. All these constants have been revealed by experiments and seem to be irrational. One example is the constant “α” (alpha), which is discussed in the first link that follows this answer.

Stephen Hawking says that the odds of a universe configured like ours are 1E500 against, which is close to an infinity. But Stephen Wolfram says that at the heart of the universe is a simple algorithm. In his view the algorithm, should anyone ever discover it, will prove that our universe is the only configuration possible.

6 – What salary in the United States puts you in the top 10%, top 5%, top 2%, and top 1% in terms of salary?

All anyone needs to know about train-wreck America is that half of all black families live on less than $40K per year; half of all non-black families live on less than $75K per year. It’s hard to imagine that families can survive, let alone prevail, on so little income.

The USA is segregated by income and race. Poor people have no idea how easy life is for the wealthy; the wealthy don’t believe America has poverty.

I have five sons and one daughter. Only two of the six are in the top 1%. The most talented one, an assistant professor of kinetic art at a major university, is in the bottom half. His brothers give him money so he can get by.

Gross inequality isn’t right.

7 – Modern humans appeared 200,000; civilization 10,000; and advanced technology 500 years ago. Why no advancement for something like 190,000 years?

Technology advances when survival demands it. Wars involving large populations did not become possible until about 3,000 years ago, because human populations were small.

Technology (to wage war) began to advance when population size increased; war technology percolated into the general population during peacetime.

70,000 years ago the human population collapsed to what some anthropologists believe was fewer than 4,000 individuals. The climb back took a long time because the world was in an ice age until 15,000 years ago or so. It has taken time to reach seven billion individuals.

The good news is that advances in technology and science are no longer driven by war, but by the preparation for war. Entertainment, comfort, convenience, and other factors drive inventors to bring clever technologies to peacetime populations.

Avoidance of war should become the highest priority of humankind from here on out, or we might suffer a catastrophic population collapse that would most certainly set back human development for hundreds of thousands of years.

Extinction is another possibility. At least two intelligent hominid species are known to have gone extinct during the past 200,000 years. There may be others.

Sorry for the short answer. The list of technologies and natural catastrophes that can annihilate homo sapiens is long. Click the following link to read about most of them.

8 – Should the USA build a competing Status-6 Oceanic Multipurpose System (Doomsday) Nuclear warhead?

Enough Pu239 has already been produced in weapons and processed from nuclear fuel rods to sterilize planet Earth of all life.

One country, Japan, has isolated 47 tons of Pu239 from fuel rods, is adding 8 tons per year, and has complained on NHK television that they don’t know what to do with it. Ten pounds is enough to make one atomic bomb.

Plutonium 239 is bomb making material. Japan has 94,000 pounds. It is producing 16,000 pounds per year. Twelve pounds makes one high-yield bomb.

The level of toxicity of Pu239 dust has recently become controversial. My understanding is the traditional one: the speck of brown dust that kills you, you will never see.

The half-life of Pu239 is 24,000 years. Risk studies (which include about a dozen hazards not related to plutonium) have shown that the chance that homo sapiens will survive a catastrophic population collapse during the next 24,000 years is less than one-in-a-million.

Humans cannot baby-sit all the plutonium that exists in facilities on every continent and keep life on earth safe from annihilation by contamination. The warheads and storage facilities are going to rot over time, and the earth will soak up the poisons left behind like vinegar in a sponge.

Doomsday is not a question of whether-or-not but of fast-or-slow. There is no upper limit to the size of a hydrogen bomb, so fast is doable. A rogue group with enough resources could construct a bomb powerful enough to obliterate Earth.

No one can undo the poisons that now exist, so slow is inevitable.

9 – What is the evolutionary reason that human beings are superficial and attracted to external appearances more than towards intrinsic qualities such as intelligence, character, integrity, honesty and virtuosity?

My reading and life experience tell me that humans are attracted to symmetry.

There could be any number of reasons, but it is easy to argue that symmetry seems to create less stress in those who encounter it, which may make them more receptive (and less reluctant) to mate with those who have it.

Reduction of cognitive dissonance is a major driver of conscious-life; symmetry seems to reduce dissonance in sentient beings like humans.

Interest by humans in mathematics and art seems to confirm, at least to my mind, that folks are driven to imbibe “harmonies” and “patterns” in nature; these symmetries provide them with reassurance that the world is not hostile and that happiness and reduction of stress is possible in the face of accidents, disease, and predators.

Intelligence, character, integrity, honesty and virtuosity are qualities that are not easily perceived and can even be illusory. People are good at feigning all these qualities to manipulate others to satisfy their needs — especially their sexual appetites and their desire for power over others.

Symmetry is not easily disguised (or the lack of it, even with good grooming) and can be an indicator of good mental and physical health, because symmetrical (attractive) people tend to have higher status and are in general less traumatized by mistreatment (on average) than people who do not have this physical quality.

People may mate with high symmetry individuals and later discover than the intangible moral qualities that they value in a life-partner are missing. Such a discovery can lead to separation, but meanwhile offspring have been spawned who have high levels of symmetry, and the process of selection for this quality continues unabated into future generations.

Yes, I have no evidence that this conjecture is correct; it’s not my field, but it seems to be a factor in the world I find myself.

10 – How does Russia stay on par with the USA in many high-tech military systems when their GDP and military budget is so small by comparison? Shouldn’t we be light-years ahead of them by now?

USA military spending is deceptive and classified.

The United States has 800 bases inside 70 countries. It is at war with every country that doesn’t do what it’s told.

Since the end of WW2, the USA has attacked one-fourth of the 195 countries on the earth. Depending on who counts, the USA has killed between 10 and 65 million people, most of them civilians. Injured people are uncountable.

The high casualty rates are due to the way it fights. The USA bombs the enemy to rubble, then moves in a few troops supported by large numbers of indigenous mercenaries to deny the rubble to the enemy.

Take two countries the size of the USA and put them side by side. The land area is less than Russia. Russia is huge. Its entire population is technically literate.

In the USA, only elites are educated. The vast majority of Americans are poorly trained, because public education is underfunded and neglected. Under the American system, education doesn’t generate profits for the wealthy, so they won’t support it.

Because America is segregated by race and income, it is difficult for visitors to get a sense of how poor the general population is. Wealthy Americans are in complete denial of the simple truth that their country is a train wreck for 75% of the people who live in it.

People with the money to travel don’t explore urban ghettos or rural wastelands. They don’t know things, nor do they want to know.

The USA has the world’s biggest and cruelest prison system for a reason.

Think about it.

Every country in the world, including Russia, is trying to avoid the wrath of the United States. They say nice things to us, so we won’t hurt them. They build as much deterrence as they can to avoid being attacked or embargoed.

It’s simple, really.

11 – Has anyone considered leaving the USA because of the gun laws?

Anyone who has to carry a gun to feel safe is living in the wrong place. My recommendation is to move to safety ASAP.

The guns that many civilians own today inflict shattering injuries that no one who is shot can recover from. The slugs are high velocity and tumble. They are designed in non-conformance with the Geneva accords and are diabolical workarounds.

I would rather die myself than fire one of these weapons at another human being, no matter what they’ve done.

We have police and soldiers who are trained to inflict mayhem when necessary to protect civilians from human predation. Why not let them do their jobs while we civilians throw our war guns away?

Carrying a high-powered weapon into a wild area that is rife with people-eating predators might be a good idea under some circumstances. I don’t have a problem with defense-by-gun against wild animals who might be trying to kill for food or fun.

My recommendation is to travel in wild areas in a way that doesn’t unnecessarily encourage attack by dumb and innocent animals — because, can we face facts? — they don’t know any better.

Animals have a right to live in a natural way and not be provoked. People are smart enough to travel in the wild and avoid unnecessary contacts with carnivores.

12- What would happen to Hitler if he was captured today?

Well, I believe he would be released and featured in the next GOP presidential debates, win the Republican nomination, lose the popular vote by millions in the general election but win the electoral college, and become president.

As a lunatic with delusions of grandeur, he might do very well indeed.

I don’t think he would kill nearly a hundred million people like he did the last time around. It is more likely closer to two billion. But hey, that leaves five billion humans to abase themselves before him, so it would be worth it, right?

Republicans, can I hear an Amen?

13 – Would you consider the USA a noble superpower when compared to other superpowers like Russia and China?

The billionaires who run the USA believe that private ownership is noble and that public ownership is ignoble. They are in a war against any form of socialism or collectivism.

Since the end of WW2, the wealthy have used the military power of the United States to attack one-fourth of the 195 countries on the earth to prevent a cascade of civilizations into communism. This war has, with a few exceptions, been enormously successful.

Today, they are fighting to consolidate their power. The billionaires of Russia, China, Israel, and the USA are dividing up the world like the New York City crime families of a few generations ago (watch the Godfather Trilogy or read the book by Mario Puzo).

Private ownership (called Capitalism) is a permutation of slavery that can be corrupting to democratic governance — as is obvious to any observer of U.S. history.

14 – How do you interpret human consciousness? Are you the center of the universe?

Consciousness is the fundamental and foundational principle of the universe. Conscious life plugs into this foundational consciousness in a way analogous to televisions plugging into a cable outlet. A television can be unplugged and replaced. But the cable programming continues. It is eternal. Consciousness is at the center of the universe. Conscious life is at the periphery.

15 – How would slavery have evolved in society if it was not seen as morally wrong?

“Capitalism” is the modern term for slavery. Owners of plantations, factories, and other businesses accrue the benefits of the plantation owners of former times.

Instead of providing slave quarters and food to their slaves, they pay a tiny stipend (called a minimum wage) to their laborers, which frees owners from the additional responsibility of caring for and protecting workers.

Putting the burden of housing, food, health care, and transportation on the backs of low-paid workers is called “freedom.”

The legal system disciplines unruly workers, while the state unemployment system helps dissatisfied owners replace those workers they believe are unfit.

For a small percentage of Americans, it’s a beautiful system.

Because the USA segregates workers both by race and income, most poor people don’t interact with the wealthy. This lack of contact between rich and poor reduces conflict and promotes peaceful living.

16 – Who was the most powerful human being that ever lived?

The most powerful person in human history was Jesus of Nazareth.

Modern calendars are organized based on the date of his birth. No one else holds that honor.

He taught the world that love — and suffering to love and save others — is what makes life worth living.

Billions have submitted their lives to the cause of Jesus, the Christ. No other human comes close.

17 – Which among these countries is the best to live? Canada, USA or Australia? Why?

My question is, which country is the best place to live if you are poor? Most people are born poor.

If people go on living by being born again after they die, the odds that they will be born impoverished is high regardless of how well they lived in their prior life. That’s why its important to make the world a good place to live for impoverished people.

Does anyone seriously believe that they only live once? Consciousness continues somewhere, and it’s all there is, right? Absent conscious-life the universe can have no meaning.

I believe Cuba is the best place to live if you are poor, because it has a good climate and the government tries to provide services to ordinary people that are available only to the well-to-do in places like Canada, Australia, and the USA.

People might want to go to Cuba to find out how the poor live on that island. Then come back and observe how the poor live in their own countries.

The United States is segregated by income and wealth, so it’s hard to find poor people if you are rich, and if you are poor it is impossible to meet rich people.

18 – Trump wants to develop a lot of smaller, “tactical” nukes. Should the US use these against North Korea?
 
The USA bombed North Korea back to the Stone Age during the Korean War.

It killed an estimated two million civilians. The bombing was led by General Curtis LeMay of the Strategic Air Command who later partnered with George Wallace when he ran for president back in the 1960s and carried several states including Michigan (if I remember it right).

Wallace was a white supremacist. The Air Force’s own official historians have called LeMay’s bombing of North Korea the cruelest use of military power in world history.

This is the same General who destroyed 67 Japanese cities and burned their populations alive with napalm (fire-jelly) during WW2.

North Korea has done nothing to justify a military strike against its territory.

Nuclear weapons of any size or type should never be used in war, especially when there is nothing to be gained but the reputation for being a monster.

What does Korea have that we could possibly want? The answer is, nothing.

We have a choice to make: are we good or evil? Our destiny depends on how we answer that question.

19 – I am terrified of single-payer systems as implemented in socialist countries. Can this happen in the US? Was Obama trying to give everyone healthcare all along?

The USA is based on a slave system (now referred to as capitalism or free-market) where the owners of the plantations have doctors, which they share with their favorite house slaves. The field hands get nothing. The plantation owners are terrified that they might have to share their doctors with “unworthy” people should a slave revolt occur, so they have built the world’s most massive prison system to isolate slaves who might dare challenge the status quo.

In other words, people have to work for the right company and have the right job to get access to free health care. Very few do.

The system is so simple, a child can understand it.

Obama threw a wrench into the system by making it possible for people who work for the wrong companies (or who don’t work at all, for whatever reason) to buy access to health care for a reduced fee. Care is still expensive, but it’s not totally out of reach anymore for about three-quarters of the population.

In Cuba (for example) every neighborhood and apartment complex has a doctor assigned to it. What could be more effective than walking down the hall or across the street to be evaluated? If necessary folks are referred for further treatment to a hospital. Otherwise they get the meds they need, and that’s as complicated and inconvenient as it gets.

I grew up in a Navy family. We had free health care. If you got sick, you just drove to the base hospital and the doctors evaluated you. No paper work, no fees. It was a “single-payer” socialized system of medicine. It was better than what we have today as civilians except that protocols, equipment, and medicines are more effective today than they were sixty years ago when I was in that Navy system.

It’s hard for me to believe that this is a serious question by a serious person, but clueless people in the USA are subject to sophisticated behavioral modification protocols due to the immense amount of money that is involved in medicine and drugs, as well as guns, entertainment, food, and transportation.

So it isn’t surprising that people fear a lot of things that aren’t dangerous and are oblivious to dangers that are serious. It’s all about helping a relatively few families and cartels sequester the lion’s share of our nation’s resources.

Someday, maybe things will become more fair than they are now. I hope so.

20 – Why is it assumed that America invented slavery when slavery has been around for much of human history?

America practiced one of the cruelest forms of slavery. It is the only country in the western hemisphere where slave revolts were successfully suppressed.

Today, slavery has been renamed; it is called capitalism. In the USA, slaves are called workers and are free to live outside the gated communities of the wealthy. Workers are segregated by income to minimize the possibility of unrest.

The USA continues to prevent a successful slave revolt by maintaining the largest prison system by far that the world has ever known.

21 – What was the worst year of slavery?

Two-thirds of white people came to America as slaves, called indentured servants. This practice started 150 years before the country became a constitutional republic and continued for many decades after. Indentured servitude was a seven year term of slavery that ended in freedom.

For Africans slavery was permanent. 100% of Africans came to America as slaves for life. There were notable exceptions. Billy Lee, George Washington’s slave and best friend, was set free when George Washington died; Billy Lee continued to live on GW’s Mount Vernon estate as a free man until his death.

22 – Is it true that until humans become one nation, we will never go further than Mars?
 
Organizing a human mission to Mars is expensive and dangerous. A coalition of nations might be able to manage the expense and risk.

Elon Musk’s company, SpaceX, is planning a Mars mission. I haven’t heard how the company plans to finance it.

Mars has an iron-nickel core like the earth, but it froze solid many millions of years ago. The magnetic field collapsed, which permitted the solar wind to blow away most of the planet’s atmosphere.

Any biological life forms on or near its surface will have to withstand the stress of continuous, high-energy radiation and the bombardment by cosmic particles with the energy of baseballs.

Travel to planets or moons as far as Jupiter and beyond will take many years.

Unless humans are heavily sedated, it is doubtful that they will be able to endure a journey of several years in a cramped space vehicle. They will lose muscle mass and possibly their sanity — certainly their perspectives that help them maintain a sense of normalcy.

Successful functioning by humans on an alien moon or planet after a journey of several years might not be possible no matter who organizes the trip or what precautions are taken.

23 – To Christians: Which scientific claims are incompatible with your faith, and why?

Science confirms my faith, because it seems to be saying that reality is mind-boggling; the odds against a universe constructed like ours with its unusual forces and constants seems to be infinite.

Jesus came to save the ignorant and the despised of the world, which is pretty much everyone. He avoided the subject of science altogether, for good reason.

No reasonable person can believe that the universe started with the big bang of a singularity that then inflated rapidly to create the conditions for conscious life with enough intelligence to understand its origins. That’s cray-cray, but it’s how some astronomers explain the universe.

Even with all we know, the underlying reality of existence remains a complete mystery. If Jesus came to Earth today, would he talk science to humanity?

I seriously doubt it. I don’t believe humans are hard-wired to understand how the universe works or what reality is. We evolved in an unusually safe place and time in the universe and carry with us all the peculiarities and idiosyncrasies that accompany our unlikely presence.

The Bible says plainly that one day people who have ridiculed God will be asked why they didn’t look up at the night sky and wonder why it is that they are so small and dark while the night sky is so large and bright.

How could serious people have missed such an important clue? How could anyone misunderstand their predicament and not concede the possibility that one day they might realize their hopes and dreams through the love of God who created, cares for, and protects them?

RESURRECTION

24 – Keeping the knowledge you have today, would you rather travel a thousand years into the future, or a thousand years into the past?

The risks to survival that faced individuals a thousand years ago far exceed the risks that people will face a thousand years from now—if humans survive another thousand years.

The counter-intuitive statistical reality is that the odds against species survival are actually higher than odds against survival of any individual human, should individual humans achieve viability during the next thousand years.

Most analysts of risk are suggesting that homo sapiens do not have much time left before extinction overwhelms them.

The geological record shows that at least two human-like species have already gone extinct. The particular species that thrives today (us) faces risks brought on by its technological expertise, which is certain to destroy it eventually.

I would choose to go forward in time, but I would do so with a great deal of fear knowing the old adage that curiosity kills the cat.

If everything turns out all right, the big question would be, how do uneducated, stupid people do in this new world?

Because uneducated and stupid is exactly what anyone will become who dares travel into a future one-thousand years more advanced than today.

25 – What are ways one can approach a complex idea that we don’t understand?

Complex ideas are of two kinds: ideas that one or more people understand but others don’t; and ideas which no one understands.

In the case where certain humans exist who understand a complex idea, the objective should be to learn what they know either by talking to them or reading what they have published. By this process, maybe folks can gather enough clues to guide them to further inquiries, which will lead eventually to understanding.

Many complex ideas require skills in certain subsets of knowledge like mathematics, languages, logic, philosophy, and the technical arts (such as metallurgy or whatnot) to make progress.

In the case where a complex idea can be demonstrated and stated but no one understands it (an example is “entanglement” in quantum physics), the approach is different. In these cases, it may not be possible to create a model of any kind in anyone’s mind to reduce the annoying dissonance that comes from not understanding.

People waste a lot of time — some go mad — trying to understand ideas no one understands or will ever understand. Most people seem to believe (in error, it seems to me) that everything can be understood if smart people work hard and are clever.

The idea, which I believe, is that complete understanding is not possible; it is a complex idea that no one understands, including me.

BONUS QUESTION 1 – In history, humans have fought and killed each other for every piece of land on the Earth. Why has the massive continent of Antarctica always been out of that conflict?

This absence of conflict may be coming to an end. A National Geographic reporter has been reporting on alarming developments in Antarctica over the past several years that the fake news has all but ignored.

BONUS QUESTION 2 – Why did mankind invent religion?

As far as I can tell, no records of an ancient civilization without religion have been discovered. I think that it is very scary to be suddenly aware that you exist and not know why — especially at night when wild animals roam freely, and the sky is full of lights that should not be there.

25 ANSWERS

Two months ago, I discovered QUORA. It’s been around since 2009.

Since 2010, Quora has enabled people to ask experts questions about topics they like; even to answer questions on subjects they claim to know something about.

Quora is a site for geeks and nerds, and so far I  like it. The people who hang out in the areas I hang out tend to be polite, kind, and smart. If they like someone, they follow them and are notified when they post. So far, ten people have signed on to follow me. It’s a start. I think most are from India.

During the first six weeks, 150 or so of my answers were viewed 35,000 times; I got nearly 175 “upvotes”, which enabled many of the answers to move to the head of the line. I wrote most answers in the wee hours between 2 AM and 7 AM when I couldn’t sleep. Insomnia inspired me.

What follows are 25 of the most popular answers I posted to the first 150 or so questions that caught my interest. They are sequenced by popularity — the most read first .

Why not read a few? How many questions can anyone answer? Not many, I’m thinking.

Who knows what you might learn?

What? 

Someone thinks they know better than a pontificator with no bonafides?

I don’t think so.

No way!   😉


1)   What are some of the most popular “mathematically impossible questions“?

Freeman Dyson — one of the longest-lived and most influential physicists and mathematicians of all time — argued that it is impossible to find a whole (or exact) number that is a power of two where someone can reverse its digits to create a whole number that becomes a power of 5.

In other words, 2^{11} = 2048 , right? Reversing the digits to make 8402 does not result in an exact number that is a power of 5.

In this case,  8402^{1/5} = 6.09363  plus a lot more decimals. It’s not a whole (or exact) number. Not only that, no matter how many decimal places anyone rounds-off 6.09363… , the rounded number raised to the power of 5 will never return 8402 exactly.

Dyson claimed that this conjecture must be true, but there is nothing in mathematics that enables anyone to write a proof. He claimed that there must be an infinite number of similar statements—-each one true, none provable.

The Snowplow Problem is another “impossible” problem. My differential equations professor assigned it with the promise that anyone who solved it would receive a 4.0 grade, regardless of their performance on tests. I was the only student he ever taught who actually managed it.

The problem goes like this: It is snowing at a constant rate. A snowplow starts plowing snow at noon. By one o’clock the plow has traveled one mile. By two o’clock the plow travels an additional half mile. At what time did it start snowing?

It took me 3 days and two pages of calculations, but I got my 4.0.

Note from the Editorial Board: Over 50 people on Quora submitted answers to Billy Lee’s Snow Plow problem. One person had the right answer, but would not produce his proof. He did point out an unusual feature of the solution that Billy Lee had not noticed before. Billy Lee characterized the feature as ”very surprising.” When pressed Billy Lee refused to reveal the secret. 

2)   How much force is one Newton?

A newton is the force that an average sized apple makes on your hand when you hold it. No matter where in the universe you are; no matter on what planet you stand or how strong the gravitational field, a newton of force always feels the same.

A newton is one kilogram of mass that is accelerating at one meter per second per second. Gravity on Earth accelerates everything at nearly 10 meters per second per second. A kilogram of mass feels like 2.2 pounds on earth. One tenth of 2.2 pounds is 0.22 pounds or 3.5 ounces, which is the weight of a typical apple. The weight is the force that you feel against your hand. It is one newton.

On the moon, an object with the mass of a large brick would feel as light as an apple on earth due to the moon’s lower gravity. The force of the brick in your hand would feel like one newton.

3)   x + y = 4 .  and  . x^x + y^y = 64 .   What are x and y?

The simplest way to solve is to make y = (4-x) and create an equation in terms of x.

An easy version to create and solve is

{x^x + (4-x)^{4-x} = 64}

You can solve it by hand using iteration or throw it into an app like Wolfram Alpha and let them solve it in a few seconds.

Either way, one value for x is .606098…. The other is 3.393901… , which you can assign to y. The two numbers add to 4.000… and when substituted into both initial equations return the right results.

4)   If I had 1,000,000,000,000,000 times 1,000,000,000,000,000 hamsters floating in space in close proximity, would gravity turn them into a hamster planet?

Assuming the question is serious, it deserves a serious answer.

A typically fat hamster weighs around one ounce, which is about 0.03 kilograms of mass. The number of hamsters in your question is 10E30.

Multiplying the mass of a single hamster by this large number gives the result of 3E28 kilograms.

To compare, the mass of planet Earth is 6E24 kilograms. The mass of the proposed population of hamsters is 5,000 times the mass of the earth.

The sun contains 67 times more mass than the hamster population. If the hamsters are close enough together to hold paws, a hamster planet is almost certain. I haven’t worked out how long the process to congeal would take, but I can estimate that the hamsters would probably die of starvation before the inexorable forces of gravity completed their work.

The hamster planet would be formed mostly from three elements: hydrogen (64%), oxygen (33%), and carbon (10%). 3% would be trace elements like calcium and maybe lithium.

The most likely outcome, given enough time, is a planet-like object. The hamsters have only one-fifth of the mass to make the smallest of the smallest suns — red dwarfs, which populate 67 to 80 percent of the Milky Way Galaxy.

There are way too many hamsters to make a reasonably sized moon.

Their mass (3E28 kg) happens to fall on the border between the range of masses that are required to form celestial objects known as brown dwarfs and the less massive sub-brown dwarfs — sometimes referred to as free-floating planets.

Brown dwarfs don’t have enough mass to ignite like a star, but they do produce heat and can accept small orbiting planets. The chemistry of brown dwarfs is not well-understood and is a bit controversial.

It’s a toss-up, but my vote goes to the notion that the hamsters will eventually form a very large but ordinary planet — a free-floating planet — which I referred to earlier as a sub-brown dwarf. This hamster planet might wander through space for millions (or even billions) of years before being captured by a massive-enough star to begin to orbit.

Because the elements of hydrogen and oxygen are likely to become the constituents of frozen moisture (or water ice), there is the risk that the ice might melt into oceans and perhaps boil away if the hamster planet approaches too close to a star (or sun). In the case where the planet loses its water, a carbon planet with 50 times the mass of earth would form.

Otherwise, should the planet find itself in a far-distant future orbiting in the “goldilocks” zone around a sufficiently massive star, the water would not evaporate. Life could arise in the planet’s oceans. It’s possible.

Life-forms might very well crawl up out of the water and onto land someday where — over the eons and under  ideal conditions — they will evolve into hamsters.

5)   Why is evolution a valid scientific theory despite the fact that it can’t be conclusively proven due to the impossibility of simulating the millions-of-years processes that it entails?

Evolution is a fact that is thoroughly established by observations made in many disciplines of science. Changes in species happen fast or slow; in the lab and in the field.

The mystery is how one-celled life got established so quickly — it was solidly established within one billion years of earth’s formation. It’s taken 3.5 billion years to go from one-celled life to what we have now.

Why so fast to get life started; why so slow to get to human intelligence and civilization?

People have a lot of ideas, but no one is sure. Some life forms have orders of magnitude more DNA than humans. Only 2% of human DNA is used to make the proteins that shape us.

So, yes, there are lots of questions.

NO CODE

6)   Why do cosmologists think a multiverse might exist?

Many high-level, theoretical physicists have written about the obvious problem our universe seems to have, which is that it has too many arbitrary constants that are too tightly constrained to be explained by any theory so far. No natural cause has been found for so many constants, so it’s fertile ground for theorists.

Stephen Hawking, among others, has said that the odds of one universe having the physics that ours has is 1E500 against. He is joking in his English way, because such a large number is essentially an infinity. It’s not possible to constrain a universe like ours by chance unless there are an infinity of choices, and we happen to be in the one that supports intelligent, conscious life.

Two ways of getting to infinity are the concepts of multi-verse and the new one proposed by Paul J. Steinhardt of Princeton University in 2013, which is based on data supplied by the Planck Satellite launched in 2003. Paul is the Einstein Professor of Science at Princeton, so his opinion holds a lot of weight.

Steinhardt has proposed that the universe is ekpyrotic, or cyclic. He has asserted 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. Each cycle produces conditions — some which are ideal for life. This heart has been beating forever and will continue to do so, forever.

Conscious Life

7)   How will we visit distant galaxies if we cannot travel faster than light? 

We will never visit distant galaxies, because they are too far away; most are moving away from us faster than our current technologies can overtake. At huge distances space itself is expanding, which adds to our problems.

The expansion of space is gradually accelerating. Any increase in performance by space vehicles over the next few thousand years is certain to be overwhelmed by the accelerating expansion of the universe.

As time goes on the amount of objects that are reachable (or even viewable) by earthlings will shrink.

On the happy side, our own solar system has at least 165 interesting places to visit that should keep folks fascinated for many thousands of years. A huge cavern has been discovered on Mars, for example, that might make a safe habitat against some forms of radiation dangers; it seems to be a place where a colony of humans might be able to live, work, and survive — perhaps even flourish.

Elon Musk is planning a mission to Mars soon.

8)   What is the mathematical proof for a+a = 2a ?

Some things that are true can’t be proved. All math systems are based on axioms, which are statements believed to be true but which, in themselves, are not provable.

This link provides a list of axioms for addition: https://sites.math.washington.edu/~hart/m524/realprop.pdf

A lot of interesting philosophical and mathematical work has been done on conjectures that are believed to be true, but can’t be proved.

TRUTH

9)   Can you explain renormalization in physics in simple words?

There is a problem in physics that has to do with the huge variation in scales between the very large and the very small. This problem of scales involves not only the size and mass of things, but also forces and interactions.

Philosopher Robert Pirsig believed that the number of possible explanations that scientists could invent for phenomenon were, in actual fact, unlimited.

Despite all the math and all the convolutions of math, Pirsig believed that something mysterious and intangible like quality or morality guided our explanations of the world. It drove him insane, at least in the years before he wrote his classic book, Zen and the Art of Motorcycle Maintenance.

Anyway, the newest generation of scientists aren’t embarrassed by anomalies. They have taught themselves to “shut up and calculate.” The digital somersaults they must perform to validate their work are impossible for average people to understand, much less perform. Researchers determine scales, introduce “cut-offs“, and extract the appropriate physics to make suitable matches to their experimental results.

The tricks used by physicists to zero in on pieces of a problem where sensible answers can be found have many names, but renormalization is one of the best known.

When physicists renormalize an equation, they cut away infinities and other annoying problems (like dividing by zero). They focus the range of their attention to smaller spaces where the vast differences in scales and forces don’t blow up their formulas and disrupt putative pairings of their carefully crafted mathematics to the world of actual observations.

It’s possible that the brains of humans, which use language and mathematics to ponder and explain the world, are insufficiently structured to model the complexities of the universe. We aren’t hard wired with enough power to create the algorithms for ultimate understanding.

RENORMALIZATION

10)   If a propeller rotates at the speed of light at half of its length, what happens to the outer parts?

Only the ends of the propeller can rotate at near light speed (in theory). At half lengths the speed of the propellers will be half the speed of their ends, because the circumference of a circle is 2πr. (There is no squared term.)

So the question is: will the propellers deform according to the rules of the Lorentz transformation along their lengths due to the difference in velocity along their lengths?

The answer is, yes.

As you move outward along the propeller, it will become thinner in the direction of rotation, and it will get more massive. A watch will tick more slowly at the end than at the middle.

I am not sure how it would look to an outside observer. Maybe such a propeller would resemble in some ways the spiral galaxies, which don’t rotate the way we think they should. Dark matter and energy are the usual postulates for their anomalous rotations. Maybe their shape and motion is related to relativity in some way. I really don’t know.

In reality, no propeller can be constructed that would survive the experiment you describe. But in theory (and ignoring the physical limitations of materials) there would be consequences.

However, no part of the propeller will move at light speed or higher. Such speeds for objects with mass are impossible.

11)   What is the fundamental concept behind logarithms?

The first thing that anyone might try to understand is that the word logarithm means exponent.

Example 1:

log 100 = 2 . What does this expression say? It says that the exponent that makes 100 is 2. What confuses people is this: exponent acting on what number?

The exponent acts on a number called the base. Unfortunately, the base is not written down in the two most common logarithm systems, which are log and ln.

The base for the log system is 10. In the example above, the exponent 2 acts on the base 10, which is not shown. In other words,  10^2 = 100 , right? The exponent that makes 100 from the base 10 (not shown) is (equals) 2.

Example 2:

ln 10 = 2.302585… .  What does this expression say? It says that the exponent that makes 10 is 2.302585… . Again, exponent acting on what number?

The base used in the ln system is 2.7182818… ,which is an irrational number that has an infinite number of decimal places. It happens to be a useful number in all branches of science and math including statistics, so mathematicians have decided to represent this difficult-to-write-down number with the letter “e”, which is known as Euler’s number.

The base for the ln system is e . In the example above, the exponent 2.302585… acts on the base e , which is not shown.

In other words,  e^{2.302585...} = 10 , right?

The exponent on e ( which is 2.7182818… and not shown in the original equation above) that makes 10 is (equals) 2.302585… .

All other logarithmic systems express the base as a subscript to the right of the word log.

Example 3:

log_{7}49 = 2

This expression says: The exponent on seven that makes 49 equals 2.

12)   Why do so many spiritual types have mental blocks about science and mathematics?

Everyone has mental blocks about science and math including scientists and mathematicians. Like the lyrics to the old song — people hear what they want to hear and disregard the rest — Einstein, to cite just one example, never accepted most of quantum physics even after it was well established and no longer controversial.

People don’t like the feeling of “cognitive dissonance”. The tension between strongly held beliefs and objective facts can bring unbearable psychological pain to most people. Someone once said that genius is the ability to hold contradictory ideas inside the mind. Most people don’t do that well; they don’t like contradictions.

Here is a link to an essay called Truth that some will find interesting:

TRUTH

13)   Is time infinitely divisible?

Einstein said that time and space (i.e. space-time) depends on mass and energy, which are equivalent. In the absence of mass and energy, space and time are meaningless.

The most recent experiments by NASA have found no evidence that time is anything but continuous. However, the shortest time possible is the length of time it takes light to move the shortest distance possible, which is called Planck time. It is thought to be 5.39E-44 seconds.

Time can be divided into as many smaller increments as anyone wants, but nothing can happen in fewer than the number of intervals that add to 5.39E-44 seconds. Time is a variable that isn’t fundamental. It expands and shrinks in the presence of mass and energy.

Some physicists of the past suggested that the “chronon” might be the shortest interval of time. It is the time light travels past the radius of a classical (at rest) electron — an interval of 6.27E-24 seconds. Its calculation depends only on mass and charge, which can change if a particle other than an “at rest” electron is measured.

It seems to me that time is probably best thought of as being continuous. That said, it doesn’t mean that mass-energy interplay isn’t pixelated — much like a digital camera image. Pixelation is critical to a conjecture concerning the preponderance of matter over anti-matter — a conjecture described in the essay CONSCIOUS LIFE.

14)   Which is bigger:   \frac{3}{5}\;  or  \;\frac{1}{9} ?

Think of fractions as pies, which are all the same size. The bottom number is the total number of pieces into which each pie is cut. The first pie was cut into 5 pieces, which are all the same size. The second pie was cut into 9 pieces, which again are all the same size.

The second pie is cut into smaller pieces than the first pie, because there are more pieces. Right?

Mice come along and eat pieces from both pies. The top number is the number of pieces they left behind; the top number is the number of pieces the mice didn’t eat.

So which pie plate has more pie on it? Is it the 5 piece pie that has 3 pieces left or the 9 piece pie that has 1 piece left?

If you think hard you will figure out that it must be the first plate that has the most pie on it. Right?  

15)   Why is a third of 30 equal to 10 and not 9.999999999, as a third of 10 is 3.33333333? 

You can make three piles of ten objects in each pile. When you count the total, it adds to exactly 30 objects. So the answer of “10” is demonstrably true, right? Three piles of ten adds to thirty.

There is no way to make three piles of any identical objects that adds to 10. Three piles of three adds to nine. Four piles of three objects adds to twelve.

We are required to make three piles of three objects and then add a piece of a fourth object to each pile that is smaller than a whole piece.

It turns out that the fourth object is 1/3 of a whole object. When these three piles of three objects plus 1/3 of an object are added up they equal exactly ten.

The problem in understanding comes from trying to grasp that 1/3 — when written as a decimal — is what mathematicians call a repeating decimal. The rules of arithmetic say that the decimal form of 1/3 is calculated by dividing “1” by “3”.

Following the rules of arithmetic when doing the division forces an answer to the problem that results in a repeating decimal — in this case, 0.333333… .

There is no way around these rules that keeps math working right, consistent, and accurate.

Sorry.

16)   Will we be able to have life extension through cloning? 

Cloning not only doesn’t work, it can’t work.

That said, the idea of cloning is to make a genetic replicant of an existing life-form. Extending life-span would require changes to the genome through other means involving changes to structures called telomeres, probably, which straddle the ends of chromosomes in eukaryotic cells.

Here is a link:  Telomere

A short discussion of cloning is included in the essay at this link:  NO CODE

NO CODE is long (11,000 words), but explains in words, pics, graphics, videos, and links some of the complexities, misunderstandings, and dangers of current genetic-engineering at an undergraduate level. It explains basic cell biology, protein production, and much more.

17)   Why does time slow down when we are on a massive planet or star like Jupiter? 

Gravity is equivalent to acceleration. Accelerating clocks tick slower, according to General Relativity, which has been confirmed by experiments. It has to do with the concept of space-time and the fact that all objects travel through space-time at the same rate.

To understand, it helps to read up on space-time, special relativity, and general relativity. The concepts aren’t easy. The universe is an odd place, but it can be described to a somewhat fair degree by mathematics.

Some of the underlying reasons for why things are the way they are seem to be unknowable.

18)   If the ancients had focused on science instead of religion, could we have become immortal by now? 

Immortality is not possible due to the odds of accidental death, which at the current rate makes death by age 25,000 a virtual certainty for individuals.

Worse: the odds for extinction of the human species as a whole are much higher — it’s a near statistical certainty for annihilation within the next 10,000 years according to experts. It seems counterintuitive, but it’s true.

RISK

19)    How do I solve, if the temperature is given by f(x,y,z) =  3x^2 - 5y^2 + 2z^2  and you are located at  (\frac{1}{3}  ,  \frac{1}{5} ,  \frac{1}{2})  and want to get as cool as possible, in which direction should you set out? 

 You want to establish what the gradient is, establish its direction, then head in the opposite direction, right?

By partial differentiation the gradient is (6x – 10y + 4z), right? You don’t have to take another partial derivative and set it equal to zero to establish a maximum, because all the second derivatives of the variables are equal to one, right? You can drop the variables out and treat them as unit vectors like i, j, & k, correct?

The resulting vector points in the direction of increasing temperature, right?

Changing the signs makes a vector that points in the opposite direction toward cooler temperatures. That vector is (-6, 10, -4).

The polar angle (θ) is 71.068° and the azimuth angle (Φ) is 120.964°. The length (or magnitude) is 12.3288. Right? (We won’t use this information to solve the problem, but I wanted to write it down should I need to refer to it to respond to any comments or to help check my work graphically.)

These directions are from the origin, and you aren’t located at the origin. To determine the direction to travel to get to (-6, 10, -4), you need to subtract your current position. Again, for reference your location is .6333 from the origin at θ = 37.8636° and Φ = 30.9638°. Right?

After subtracting your position vector from the gradient vector, the resulting vector is (-6.333, 9.8, -4.5). Agree?

This vector tells you to travel 12.506 at a polar angle (θ) of 68.9105° and an azimuth angle (Φ) of 122.873° to intersect the gradient vector. At the intersection you must change direction to follow the gradient vector’s direction to move toward cooler temperatures at the fastest rate.

I haven’t graphed out the solution to double-check its accuracy. You might want to do this and let me know if you agree or not.

20)   What is  \sqrt[3]{i} - \sqrt[3]{i}  equal to?

The answer is zero, of course.

But not really. It only seems that way. Each number has three roots.

Depending on which roots are chosen the result can be one of six different sums (as well as zero if both roots are the same). We have to start somewhere so:

What is  i^\frac{1}{3} ?

i =  e^\frac{{i\pi}}{2} .  Right?

Therefore, a third root of i is  e^\frac{{i\pi}}{6} .  Right? It’s not the only root.

It’s the principal root. There are three third roots, which are equally spaced around the unit circle. Right?

It’s clear by inspection that to be equally distributed around the unit circle the other two roots must be  e^\frac{{i5\pi}}{6}  and -i.  Right?

Convert the three roots to rectangular coordinates and do the subtractions.

Here are the roots in rectangular form: (.86603 + .50000 i) , (-.86603 + .50000 i) , and (0.00000 -i).

Here are the six answers (in bold type) to the original question with the subtractions shown to the right:

1.7302 = (.86603 + .50000 i) – (-.86603 + .50000 i)

(.86603 +1.5 i) = (.86603 + .50000 i) – (0.00000 -i)

-1.7302 = (-.86603 + .50000 i) – (.86603 + .50000 i)

(-.86603 + 1.5 i) = (-.86603 + .50000 i) – (0.00000 -i)

(-.86603 – 1.5 i) = (0.00000 -i) – (.86603 + .50000 i)

(.86603 – 1.5 i) = (0.00000 -i) – (-.86603 + .50000 i)

These rectangular coordinates can be converted back to the Euler-form ( e^{i\theta} ).  It’s easy for anyone who knows how to work with complex variables. In Euler-form the angle in radians sits next to i.  The angle directs you to where the result lies on a unit circle. Right?

In fact, the six values lie 60 degrees apart on the circumference of a circle whose radius is the square root of 3. I don’t know what to make of it except to say that the result seems unusual and intriguing, at least to me.

As mentioned earlier, if both roots are chosen to be the same, then in that particular case the result is zero.

21)   What is tensor analysis and how is it used in physics?

Understanding tensors is crucial to understanding Einstein’s General Theory of Relativity.

This question seems to assume that everyone knows what tensors are and how they are represented symbolically. It’s a good bet that some folks reading this question might want some basics to better understand the explanations of how tensors are used for analysis in physics.

If so, here are links to two videos that together will help with the basics:

22)   What is the velocity of an electron?

Electrons can move at any speed less than light depending on the strength of the electro-magnetic field that is acting on them. Inside atoms electrons seem to move around at about one-tenth of the speed of light. You might want to check me on this number. The situation is as complicated as your mind is capable of grasping.

When interacting with photons of light electrons inside atoms seem to jump into higher or lower shells or orbits instantaneously. That said, it is impossible to directly observe electrons inside atoms.

On an electrical conductor like a wire, electrons move very slowly, but they bump into one another like billiard balls or dominoes. The speed of falling dominoes can be very high compared to the speed of an individual domino, right?

So, the answer is: it all depends…

23)   What exactly is space-time? Is it something we can touch? How does it bend and interact with mass? 

Spacetime, according to Einstein, depends on mass and energy for its existence. In the absence of mass and energy (which are equivalent), space-time disappears.

The energy of things like bosons of light — which seem to have no internal (or intrinsic) mass, right? — is proportional to their electric and magnetic fields. Smallest packets of electromagnetic oscillations are called photons.

Many kinds of oscillating fields, like electromagnetic light, permeate (or fill) the universe. In this sense, there is no such thing as nothing anywhere at any scale.

Instruments and tools of science (including mathematics) can give a misleading impression that at very small scales massive particles exist.

According to the late John Wheeler, mass at small scales is an illusion created by interactions with measuring devices and sensors.

Mass is a macroscopic statistical process created by accumulations of whatever it is that exists near the rock bottom of reality where humans have yet to gain access. These accumulations, some of them, are visible to humans; they seem to span 46 billion light years in all directions from the vantage-point of Earth and are displayed for the most part in as many as two-trillion galaxies according to recent satellite data by NASA.

Mass is thought to interact with everything that can be measured (including everything in the Standard Model) by changing its acceleration (that is, its velocity and/or direction), which is equivalent to changing its momentum.

It is in this sense that mass and energy are equivalent. Spacetime depends on mass and energy. Spacetime does not act on mass and energy; it is its result, its consequence. 

Spacetime is a concept (or model) that for Einstein helped to quantify how mass and energy behave on large scales. It helped explain why his idea that the universe looks and behaves differently to observers in different reference frames might be the way the universe on large scales works.

His mathematical description of spacetime helped him build a geometric explanation for gravity that can be described for any observer by using tensor style matrices; many find his approach compelling but difficult computationally.

WHY SOMETHING, NOT NOTHING?

24)   Hypothetically speaking, if one could travel faster than light, would that mean you would always live in the dark?

The space in which objects in the universe swim does expand faster than light when the expansion is measured over very large distances that are measured in light-years. A light year is six trillion miles.

At distances of billions of light years, the expansion of space between objects becomes dramatic enough that light begins to stretch itself out. This stretching lengthens the distance between the peaks and valleys of the electric and magnetic waves that light is made from, so its frequency appears to drop.

The wave lengths of white light can stretch so dramatically that the light begins to appear red. It’s called red shift.

Measuring the red shift of light is a way to tell how far away an object like a star is. As light stretches over farther distances the ability to see it is lost.

The wavelengths of light stretch toward the longer infra-red lengths (called heat waves) and then at even farther distances stretch to very long waves called radio-waves. Special telescopes must be placed into outer space to see these waves of light, because heat and radio waves radiating from the earth will interfere with instruments placed at the surface.

Eventually the distances across space become so great that the amplitudes (or heights) of the waves flat line. They flat-line because space is expanding faster than light can keep up. Light loses its structure. At this distance the galaxies and stars drop out of the sight of our eyes, sensors, and instruments. It’s a horizon beyond which the universe is not observable.

No one knows how big the universe is, because no one can see to its end. The expansion of space — tiny over short distances — starts to get huge at distances over 10 billion light years or so. The simple, uncomplicated answer is that the lights go out at about 14.3 billion light years.

Because there is no upper limit to how fast the universe can expand, and because the objects we see at 14.3 billion light-years have moved away during the time it has taken for their light to reach Earth, astronomers know that the edge of the universe is at least 46 billion light years away in all directions. Common sense suggests the universe might be much larger. No one has proved it, but it seems likely.

Over the next few billion years the universe that can be seen will get smaller, because the expansion of space is accelerating. The sphere of viewable objects is going to shrink. The expansion of space is speeding up.

The problem will be that the nearby stars that should always be viewable (because they are close) are going to burn out over time, so the night sky is going to get darker.

Most (4 out of 5) stars in the galaxy are red dwarfs that will live pretty much forever, but no one can see them now, so no one will see them billions of years from now, either. Red dwarfs radiate in the infra-red, which can only be seen with special instruments from a vantage point above the atmosphere.

Stars like our sun will live another 4 or 5 billion years and then die. The not-too-distant future of the ageless (it seems) universe is going to fall dark to any species that might survive long enough to witness it.

25)   What does “e” mean in a calculator? 

There are two “e”s on a calculator: little “e” and big “E”.

Little “e” is a number. The number has a lot of decimals places (it has an infinite number of them), so the number is called “e” to make it quick to write down.

The number is 2.71828… . The number is used a lot in mathematics and in every field of science and statistics. One reason it is useful is because derivatives and integrals of functions formed from its powers are easy to compute.

Big “E” is not a number. It stands for the word “exponent”, but it is used to specify how many places to the right to move the decimal point of the number that comes before it.

5E6 is the number 5,000,000, for example. The way to say the number is, “five times ten raised to the sixth power”. It’s basically a form of shorthand that means 5 multiplied by 10^6 .

Sometimes the number after E can be negative. 5E-6 would then specify how many places to the left to move the decimal point. In this case the number is 0.000005, which is 5 multiplied by 10^{-6}.

Bonus Question 1 – What difficulties lie in finding particles smaller than quarks, and in theory, what are possible solutions? 

The Standard Model is complete as far as it goes. Unfortunately, it covers only 5% of the matter and energy believed to exist in the universe.

And humans can only see 10% of the 5% that’s out there. We are blind to 99.5% of the universe. We can’t see energy, and we can’t see most stars, because they radiate in the infra-red, which is invisible to us.

The Standard Model doesn’t explain why anti-matter is missing. It doesn’t explain dark matter and energy, which make up the majority of the material and energy in the universe. It doesn’t explain the accelerating expansion of the universe.

Probing matter smaller than quarks may require CERN-like facilities the size of our solar system, or if we’re unlucky, larger still.

We are approaching the edge of what we can explore experimentally at the limits of the very small. Some theorists hope that mathematics will somehow lead to knowledge that can be confirmed by theory alone, without experimental confirmation.

I’m not so sure.

Bonus Question 2 – What if science and wisdom reached a point of absolute knowledge of everything in the universe, how would this affect humanity?   

Humanity has reached a tipping point where more knowledge increases dramatically the odds against species survival. Absolute knowledge will result in absolute assurance of self-destruction.

Astronomers have not yet detected advanced civilizations. The chances are excellent that they never will.

Humans are fast approaching an asymptotic limit to knowledge, which when reached will bring catastrophe — as it apparently has to all life that has gone before in other parts of the universe.

Everywhere we look in the universe the tell-tale signatures of advanced civilizations are missing.
