FLASH CARD ANSWERS

Wisdom can be condensed and gurgitated easily by anyone who has experienced a lifetime of learning, experimentation, and the testing of limits. No one understands America who has not spent time in its ghettos and prisons; in its jails and colleges; in its military and its resorts; in its paradises and hells. 

No one who’s never been both rich and poor knows what either is like; rich and poor is what the majority of Americans are. The ten percent who consider themselves middle-class know almost nothing about either — rich and poor is how ninety percent of the population lives –with ninety percent of the ninety percent living poor. 

I know things — amazing things that most people believe are not true. I’ve lived all over the world; worked for over a dozen companies; attended a dozen schools; trimmed gravestones in Arlington National Cemetery and invented products everyone uses — like milk carton safety caps and tear-spout coffee lids. I developed products of war — like the run-flat wheel that enables military vehicles with shot-out tires to keep rolling. 

My truth is not reflected in media or in the faces of my family and friends. I have secrets, which many want kept until I sleep in the grave. When speaking truth, they tell me to stop; when I continue, some walk away. 

So be it. 

People on Quora.com ask me (and others) for answers to questions. What follows is a small sample of questions I’ve answered.  Readers can scan to find something they like. Find something interesting and read a flash card answer, which is my version of what might be true. Copy answers onto index cards. Who will stop you?

I admit: some answers are not true.

Who will find what’s fake?


If objects in the universe are moving away from us in all directions, are we the center according to the Big Bang theory?   
It’s not true that all objects are moving away from us. The Andromeda Galaxy is heading toward us (the Milky Way); the collision is due in a few billion years; it’s likely that the black holes at the center of both galaxies will interact with unpredictable results.

The material in the universe can be compared to the dust in a household vacuum cleaner that is shaken loose into a large room. Over time the individual particles will separate to fill the space, but what an individual particle will do is not knowable, at least not right away.

That said, we know for certain that the metrics of space are changing; it is an expansion that is increasing with time.

Currently the rate of expansion is 14 miles per second for every million light years (a distance of nearly six-million-trillion miles). It seems like a small number until you do the calculation for the size of the universe. Past the “event horizon” of 14 billion light years the expansion exceeds the speed-of-light.

Do the math.

What is the future of a universe that is undergoing a runaway expansion?

A conjecture has been proposed by mathematician Sir Roger Penrose called Conformal Cyclic Cosmology (CCC). Data gathered by recent satellites seems likely to strengthen his view.


What is wrong with the question “What existed before the Big Bang?” I have been told that this question doesn’t make sense, but I have never heard a decent layman’s explanation as to why. 
The question is sensibly answered by the theory proposed by Roger Penrose: Conformal Cyclic Cosmology or CCC, sometimes referred to as Eon Theory.

The conjecture was proposed around 2004, I think, but collaborating evidence is only now becoming available through data collected by the WMAP and Planck satellites, and by LIGO.

The premise is that in both the singularity and a maximally expanded universe the degrees of freedom of gravity, which is associated with “mass”, drop out of the metrics. Without mass it is not possible to differentiate the initial and terminal states of the universe by scaling; the two states are in fact conformally equivalent.

The Big Bang emerges from a maximally expanded universe; the cycle repeats endlessly like a chugging choo-choo train whose next puff seems to emerge from the dispersion of the last puff; time has no beginning and no end.


If or when the universe ends someday and ceases to exist, could it be created again as it was in the beginning? 
The idea by Roger Penrose, retired mathematician and cosmologist, that the universe is conformally equivalent at its beginning and end is gathering evidence from the WMAP and Planck satellites that acolytes who do the math claim might be confirmational.

Evidence may also be buried in the data collected by LIGO, according to Penrose. He’s urging folks to dig through the data to find it.

Conformal Cyclic Cosmology (CCC) — some call it Eon Theory — has been exciting for the past 15 years, but only in the past few years has data been available to help validate what at first seemed to some like a crackpot idea.


Is it safe to have a nuclear reactor in a submarine?

Of course not.

Of the 82 nuclear submarines deployed or under construction by the US Navy, two have sunk (the Scorpion and Thresher).

It’s 2.5%, which for me is too high.

In war, all USA subs will be destroyed at sea by enemy fire during a first strike surprise attack.

The USA will destroy all adversary nuclear subs with a coordinated and long-planned after-strike.

Large numbers of nuclear reactors and their poisons boiling at the bottom of oceans are a threat to every living creature on Earth.

The nuclear genie needs to be put back in its bottle. It should be the highest priority of the international community if humans are to have any chance at all to continue as a species for more than a few hundred years.

All personnel engaged in warfare preparation involving nuclear weapons are subject to sophisticated arguments in training fashioned by psychologists to ensure their enthusiastic support of nuclear weapons and a solid belief in their own personal safety.

I beg these trained individuals to use their common sense.

      Don’t we live under a nuclear reactor called the Sun? It does no harm. 
We would die, everyone of us, if Earth didn’t have a magnetosphere to deflect the solar wind; the field works with nitrogen and oxygen to make Earth’s atmosphere opaque to high energy radiation from the Sun. It doesn’t work the same way for Earth-generated radiation.

Nuclear power is not safe; on so many levels, it never will be. A world with 10,000 nuclear reactors and 50,000 nuclear warheads is a planet doomed to extinction, if not in the near future, then in the long, for sure.

     Scrap nuclear deterrence? What?
We need to learn to work with people who have different ideas about what life is and how it should be lived. We don’t have much time to learn. The danger is imminent; the need is urgent.

Even without war, the poisons of rotting reactors and weapons will percolate into the environment over time. We’ve already destroyed the planet.

If humans survive, people will someday forget about the weapons; they will rot unattended and unremembered. A few thousand years from now people might wonder why everyone they know is sick and dying.


In hindsight, was going to Iraq justifiable?
Was killing a million human beings and destabilizing the Middle East justifiable?

What does an enemy of the United States have to do to suffer such consequences? Almost all the “facts” the Bush family “shared” with Americans and the rest of the watching world about Saddam and the Iraqis were bald-face lies.

The damage is that people believe these lies to this day. Their misunderstanding of what happened distorts everything they believe and do.

We will never get it right when Americans’ views are twisted out of all proportion to realities.

Is the situation dangerous in the Middle East?

After all the blood-letting, are things better or worse?


How was the first cell created? Can we replicate those circumstances?
No one knows how the first cells were created. It is a mystery of science likely never to be solved.

What is known is that cellular life began on Earth almost immediately after it cooled sufficiently to be safe for life, which unravels at temperatures above 300 degrees or so Fahrenheit.

The first cells were thousands of times smaller than the cells that make the plants and animals of today. These tiny prokaryotes persisted for a few billion years until the larger eukaryotes evolved.

Once eukaryotes developed the ability to convert sunlight into energy through photosynthesis, they produced huge volumes of a byproduct called oxygen, which poisoned most prokaryotic life on Earth during that time.

Prokaryotes able to adjust to the presence of oxygen survive today, mostly as bacteria and archaea.


Does socialism only work in small countries?
Any system that is supported by the people who live under it works well — especially socialism.

The problem for socialism is interference by the United States. It is the policy of the USA to disrupt and prevent — to the point of war if need be — the success of socialism anywhere.

The reasoning is simple. When socialism succeeds, billionaires are at risk. They don’t share well, and some are willing to kill anyone who tries to undercut their power.

Read the news: what wealthy people do is disgusting. Don’t make me explain. Get your head out of the sand, anyone who doesn’t believe it.

The pharaohs made the Egyptian system work. They built pyramids. The Russians were first into space and first to the moon. The Germans produced the scientists who propelled civilization into the future after WWII.

Slavery inside the USA clothed the world in cotton.

Pick a system, any system, and it can be made to work as well as any other.

If billionaires can convince cotton-pickers that life is good, who will challenge them?


What was the real reason why the USA lost the war against Vietnam?
The USA killed two-million Vietnamese. The Vietnamese killed fifty-eight thousand Americans. The USA thoroughly trashed Vietnam and poisoned the country-side with Agent Orange defoliants. The Vietnamese didn’t knock down a single structure inside the United States.

The USA deployed a program to assassinate over one-hundred-thousand South Vietnamese men and women it suspected of siding with the North. No such program of civilian murders was carried out by the North.

The Americans and their allies napalmed entire villages and executed both civilian and animal survivors. Not a single village was ever cremated by the North.

The USA carpet-bombed huge swaths of Vietnam daily for twelve years. The North didn’t have an effective air force.

It was a one-sided fight from the beginning. The USA killed and murdered until its leaders’ lust for blood was satiated. When nothing was left to prove and the thrill of the kill faded, the United States pulled out its troops and went home.

The whole world knows what we did. The reason the international community of nations doesn’t confront us for doing bad things is because we scare them.

The families of tens-of-millions of the dead cry out to God to settle scores; they pray for justice.

Americans trust — as the Germans, the Japanese, and the Romans before them trusted — that justice never comes.


Who is Donald Trump’s base? Why is he popular? Why are people voting for him? Why do people like and support him?
Trump lost the popular vote in 2016 by nearly eleven million votes. Three million went to Hillary; eight million to third party candidates. It was the biggest loss by popular vote in the history of USA elections.

Losing the popular vote by 8% yet securing the electoral college is a result that will live in infamy.

The first election after his “victory” was in 2018 when the largest swing of Republican districts to Democrats occurred in the history of the contests between Republicans and Democrats.

Trump is the most unpopular man to hold the presidency in my lifetime.

Why do his supporters love him?

My view is that in every country people exist who are attracted to bad things like moths are to flames. History shows that in Germany, people loved Hitler. The allies forced the German population to tour the concentration camps, because otherwise no one in Germany would believe their government committed genocide.

Trump is doing bad things to powerless people — not only to mothers and children at our southern border but in the middle east, far east, and around the world.  His decisions are making a more dangerous world; it’s possible that tens-of-millions of innocents will die should he continue to trash the edifice that has enabled Earth to avoid nuclear war during the past 75 years.

We must avoid nuclear catastrophe for thousands of years more if we are to become the great space-faring civilization many people seek. We can’t go to the stars if Earth is poisoned by plutonium.

People have a dark side. Philosophers, psychologists, and priests have argued this point for millennia. Evidence is solidly on their side. Political campaigns are waged using “hidden persuaders” that appeal to the reptilian nature of human conscious thought. These persuaders are built from the bricks of fear, sexuality, aggression, and cruelty. They work.

Until people learn to turn away from the dark side, survival of civilization is at risk.

Leaders like Hitler and Trump are inevitable and unavoidable. It will be interesting to learn whether America’s great experiment in divided government will survive Trump’s attempt to undermine it so that he can become a king of sorts whose family members will succeed him in their quest for ultimate power.


What do you find interesting about physics?
The science of physics is all about explaining what is happening but not why. It’s interesting to me that the smartest scientists in the world can’t tell anyone why anything works the way it does.

The universe is governed so far as anyone knows by forces and constants that are unknowable, underivable, and unexplainable. All anyone can know is what happens; no one understands why.

Billions of dollars are spent to determine that gravity behaves according to certain rules. Experiments to discover the measure of forces and constants are always being done and refined. But where do the rules come from that make the forces and constants? What principles underlie the formation of the Universe?

Good luck to anyone who finds someone who knows why. Scientists laugh at the philosophers who try to provide clues to the why of things; it’s because some scientists are arrogant and ignorant. They don’t believe that what little they know is almost nothing at all.

Even animals as dumb as cats, goats, and birds calculate distances in their heads to make survival decisions based on their answers. Like humans they have no clue about the why of things, either.


What must happen for all Americans to accept the same truths?
Reduce the number of television and radio channels to one. Restrict diversity of content on the internet. Reduce the number of people who think “outside the box.” Put them into prisons or execute them, whichever is cheaper.

Torture people who refuse to think like everyone else. Others will “get the message” and adjust their thinking to conform to the American Way.

Eliminate elections — they stir-up people unnecessarily.

Reduce the wages of the 99% to subsistence; pay the 1% as much as possible to encourage them to embrace conformity.

Build impenetrable walls on all borders. Malcontents must not be allowed to leave; they might spread anti-American ideas abroad.

Do these things and Americans will accept the same truths. They will present a united front against anyone who might dare to challenge them.


What shocked you the most from the Mueller report?
The most shocking aspect of the report is the absence of any mention of or investigation into the president’s wife who is the daughter of a former member of the communist party of Yugoslavia back in the day.

She was born when DT was 24 years old. Was she groomed for the job she currently holds? Can America rule out with confidence that she is not a sleeper agent? She immigrated to the USA not too many years ago. It would be nice to hear that she is trustworthy.

It is clear from the report that DT is working for the other side. No one will say that the emperor has no clothes. Is it fear of the Russian-Israeli mob bosses, or is it something else?

Why is everyone in denial when the truth is obvious? How can Mueller say there was no conspiracy when the report screams that there was?

As for obstruction of the investigation, no sensible person needs a report to understand the extraordinary lengths that the president and his team traveled to discredit the people who defend Americans against despots and liars like the ones we currently endure.

The president has the power to hurt a lot of people should he go postal, which he seems in his tweets to threaten from time to time.


What are volcano eruptions good for?
Volcanism permits the release of heat generated by the radioactive decay of uranium, thorium, and potassium in Earth’s interior. The release of heat permits convection currents in the liquid part of Earth’s core — without these currents the magnetosphere collapses, which puts the survival of all life at risk due to dramatically increased exposure to charged particles from solar and cosmic radiation.


When will the earth’s core cool down enough to make the magnetic field too weak to counter the suns solar storms?
Earth’s magnetic field depends more on convection currents in its molten metallic core than on its temperature. If the core gets too hot, it cannot sustain a magnetic field.

For convection currents to circulate, heat must be generated, but it must be able to escape so that it doesn’t build up.

Earth’s crust or mantle is cracked like the shell of a hard-boiled egg.

Crustal pieces called tectonic plates move about to permit volcanism and venting faults, which release the heat that is generated by the radioactive decay of uranium, thorium, and potassium in Earth’s interior.

Earth’s core is the size of the planet Mars. It is solid at the center with a liquid (but highly viscous) outer layer. The solid center stays solid because of the pressure it is under; it is too hot to be magnetic. The outer liquid center is also under pressure; it must circulate to generate Earth’s magnetic field; otherwise the field will collapse; the protection it offers Earth against the solar wind will die.

Venus has a solid-liquid core like Earth’s but no tectonic plate activity to release heat and permit convection currents. As a result, Venus lacks a magnetosphere to shield it from cosmic radiation and solar flares.

The core of Mars froze solid millions of years ago. With no magnetosphere and little gravity, over time the solar wind has been able strip away a sizable portion of the Martian atmosphere. Only the heaviest gas is left in more than trace amounts: carbon dioxide.

I’ve read that geologists believe that the dynamics which generate the magnetosphere of Earth are robust and will last as long as the planet. Let’s hope they are right. 


I have heard from Conservatives that Communism killed millions of people. Leftists claim that Capitalism killed the same. Which economic system has killed more people, and how are these numbers figured?
Since the start of the first World War until today two countries have killed the majority of people who have died in fights between nations: Germany and the United States.

During their killing sprees, oligarchs in both countries built and nurtured vast military-industrial alliances that automated mayhem and suffering. The rapid killing of humans began with chemicals, advanced to automated machine gunnery, and culminated in the deployment of atomic bombs and massive aerial bombardment of cities with fire-jellies known today as napalm.

During WWII, Germany attempted a partially successful ethnic-cleansing of Jewish populations in Europe and the Middle East. After the war against Germany was won, the United States and Russia worked together to orchestrate the execution of 100,000 German citizens for war-crimes. It was a small fraction of the numbers killed during that war, which some analysts believe approached 100 million souls.

It occurred to me that your question might be asking about which system, Capitalism or Communism, killed the largest number of its own subjects as it struggled to stand itself up and establish itself.

My view is that Capitalism is a euphemism for slavery. The word was invented to put a positive spin on the system in the USA where everyone works to enrich a privileged few. USA oligarchs needed an attractive term for their system when it came under popular challenge around the world by Communists during the twentieth century.

Communists believed that people should cooperate to create wealth, which they then shared. This kind of thinking was anathema to those who believed that only the people who risked their fortunes were entitled to the wealth created by their subjects (workers or slaves).

Through this lens, it is clear that Capitalism (or slavery) in the USA — the one country in the modern world able to preserve its slave system — decimated its indigenous populations and oppressed the Negro population under the cruelest form of slavery that has yet existed on Earth.

Oligarchs known as robber barons permitted the killing of thousands of ordinary workers during the building of the nation’s infrastructure, not only in mines, on road and railway systems, and on dams but also in unregulated sweat shops hidden behind the invisible walls of poverty in overcrowded cities.

The United States has a media system owned by a handful of families that sustains itself on advertising revenue. The practice of advertising in the USA is sophisticated. Psychologists help oligarchs maximize their advantages by crafting messages to modify the attitudes and behaviors of ordinary people.

Billionaires (most of whom are well-dressed thieves) hold themselves up as pillars of virtue and civic service in the media they control. They fight wars to secure the resources of countries like Venezuela, Brazil, Vietnam, Japan, etc. etc. They explain these wars to the public as righteous acts against evil powers.

It’s sickening.


If something is 40 million light years away, how long will it take for the light to reach us?
A light-year is a distance, which is 5.8786 trillion miles. 40 million light-years is a distance of 235 trillion miles.

Space expands at 14 miles-per-second per million light-years. For objects separated by a distance of 40 million light years, space expands at 560 miles per second.

Every million years, as the light from an object approaches Earth, the expansion of space will decrease by 14 miles per second, because the distance between the incoming light and Earth will be decreasing.

Therefore, it is certain that the time it takes light that started its journey 40 million light-years distant from Earth will take more than 40 million years to reach us. Right?

The first million light-years will take close to an additional 3,006 years due to the expansion of space. Each million light years of reduced distance will add less travel time until the added time becomes insignificant, because as the distance between the incoming light and Earth falls to zero so does the expansion of space.

If we take half of 3,006 years to be the average added time per million light-years, a simple calculation that doesn’t involve calculus will be a close approximation of the additional time traveled.

Do the math to learn that the added time of travel is 60,120 years due to the expansion of space alone.

Light 40 million light-years away takes 40,060,120 years to reach Earth.


The answer to whether or not our own consciousness has anything to do with how a wave or a particle manifests in physics seems to change completely with whoever answers it. Is there any real way to prove this?
Richard Feynman said once that he believed the underlying nature of reality is unknowable. Violations of Bell’s inequality in quantum entanglement cannot be visualized by models or any sort of mental imagery.

Something that can be described by mathematics but not explained by words or imagery is probably 95% of reality for the species-human. We are tadpoles in a muddy pond who struggle in vain to understand a world we will never see.

It has been known for a hundred years that when humans conduct an experiment on nanoscale particles they affect the results during their observation of both the process and the outcomes. Every kid who does the several variations of the double-slit experiment learns that it is true.

Engineers take what works and turn it into miracles that no one understands — the digital device folks use to view my answer is incomprehensible to most. Some understand parts, but it takes a team to understand the whole.

People crave certainty. Quantum observations prove that certainty is a quixotic quest doomed from the start. People want to believe that what they think “must be true” is provable by both logic and experimental verification.

Unfortunately for those who don’t tolerate cognitive dissonance well, everything and nothing is both provable and falsifiable depending on which axioms are chosen as starting points.


What elements do scientists use to estimate the age of the Earth?
They use isotope ratios. Although 118 elements make up the periodic table, the elements have thousands of isotopes, right?

For example, lead can be separated into eleven groups — each group has a different weight. The weight differences are the result of the number of neutrons in the nucleus. The more neutrons, the heavier the isotope. Four of the isotopes of lead are stable — they don’t decay into other isotopes or other elements.

All chemical properties of the 118 elements in the periodic table are determined by their electrical structure, which is the number of electrons they carry. Neutrons add weight carried in the nucleus but otherwise are irrelevant to the simple chemical behaviors of the elements.

To estimate the age of Earth, scientists study the composition of zircon, a common silicate element in Earth’s crust. Zircon is lead averse. Any lead found in zircon must be the result of radioactive decay of either uranium or thorium, which are common impurities. These impurities are radioactive and can over time change the color of zircon as they break down its crystal structure.

One of the isotopes of uranium has a half-life of 4.47 billion years; another isotope has a half-life of 710 million years. Both isotopes decay to stable isotopes of lead.

So the process is to measure how much of each isotope of uranium is contaminating the zircon sample and how much of that uranium has decayed into the two isotopes of lead that are stable; that don’t decay any further. This method can measure the age of the earth to a precision of 50 million years.

Earth’s age is believed to be 4.543 billion years.


Does it seem odd that such a useful trait like high level cognitive function is not more common in Earth’s life-forms? 
Once a species (humans) reaches a certain level of intelligence, other intelligent creatures become a source of fear and loathing.

Imagine raccoons or squirrels equipped with human intelligence. They are able to out-game us, work their way into living spaces, even sneak up in the night to kill us with their imaginative weapons.

After the kill, they sneak into refrigerators by deploying ingenious levers and pulleys to take and eat cold pizza and left-over wiener-schnitzel.

How long will people put up with such behavior before they go on an extermination campaign?

In New York City extermination campaigns against intelligent rats have already begun. It might take a hundred years, but eventually rats with sense will refuse to live in NYC.

Over hundreds-of-thousands of years collections of intelligent creatures have devolved to fear and mistrust other collections of intelligent creatures. The lust for war has entered human DNA to the point that people search for differences among themselves to justify mass-slaughter and genocides.

What is less subtle than skin color or religion or immigration-status? All these “superficialities” have been used as an excuse to attack and kill “others” no matter how similar or different — some of whom, as I write, are watching from their burrows in horror as they plan their assaults on the species human.

The Kingdom of Animals does not distinguish between our physical and moral differences. Humans deserve to die for their cruelties. With every squashed bug, fear and loathing intensifies. Even now legions of mosquitoes and Japanese beetles plan their revenge.

This summer they will extract it — even as most humans occupy themselves with arguments pro-and-con about what a hair-ball the president has turned out to be.

Only when humans destroy themselves and go extinct will intelligence get its chance to bloom within the diversity of species that occupy the planet. By then extra-terrestrials will have found Earth and enslaved it.

It is in this sense that the species-human will achieve its revenge against the intelligent squirrel and raccoon; against the mosquito and beetle who so often drove people to distraction when they dominated Earth.


Billy Lee

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.

NO CODE

RISK


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.

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.

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?

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

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.

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.

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.

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:

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.

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.

The link below will direct readers to an essay about the problem of the very small.

ON THE VERY SMALL

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.
