Brian Greene - What Was There Before The Big Bang?
Jun 12, 2021

Science Time - The Planck Epoch

The American theoretical physicist, Brian Greene explains various hypotheses about the causation of the big bang. Brian Greene is an excellent science communicator and he makes complex cosmological concepts more easy to understand. 

The Big Bang explains the evolution of the universe from a starting density and temperature that is currently well beyond humanity's capability to replicate. Thus the most extreme conditions and earliest times of the universe are speculative and any explanation for what caused the big bang should be taken with a grain of salt. Nevertheless that shouldn't stop us to ask questions like what was there before the big bang.

Brian Greene mentions the possibility that time itself may have originated with the birth of the cosmos about 13.8 billion years ago.

To understand how the Universe came to be, scientists combine mathematical models with observations and develop workable theories which explain the evolution of the cosmos. The Big Bang theory, which is built upon the equations of classical general relativity, indicates a singularity at the origin of cosmic time. 

However, the physical theories of general relativity and quantum mechanics as currently realized are not applicable before the Planck epoch, which is the earliest period of time in the history of the universe, and correcting this will require the development of a correct treatment of quantum gravity.

Certain quantum gravity treatments imply that time itself could be an emergent property. Which leads some physicists to conclude that time did not exist before the Big Bang. While others are open to the possibility of time preceding the big bang.

One of the common misconceptions about the Big Bang model is that it fully explains the origin of the universe. However, the Big Bang model does not describe how energy, time, and space were caused, but rather it describes the emergence of the present universe from an ultra-dense and high-temperature initial state. It is misleading to visualize the Big Bang by comparing its size to everyday objects. When the size of the universe at Big Bang is described, it refers to the size of the observable universe, and not the entire universe.

creatio ex nihilo - creation of something from nothing.
creatio continua - the reordering or process creation of something which always was, is and will continue to be in whatever manner or forms of energy it is or will become.
In the vacuum of space there is no void. The vacuum of space has continuous exotic activity in the form of anti-mater particles+forces instantaneously annihilating with non-anti-matter particles+forces with the tiniest of fractions of matter particles+forces surviving to give to the universe it's quantum densities and structure which it has today.

Conclusion. The Hebraic idea of void though correctly imagined and unseen is actually the vaduumous activity of space which is filled with unseen force energies. The God who created, did not create from nothing. There was always something there... even before the "voids" of space. This there which was there is the primodial energy forces which existed before the Big Bang before time and before matter.
What was there? Energy in it is purest potential states inhabiting a 1 dimensional space of "liquid" plasma in the severest heats of radiation with no irregularities to give it its start. Moreover, God and these states of potentiality always existed. Neither is older than the other with the philosophical difference that God is the first and primary process before all other process forces. Sic, Process Philosophy, Theology, and Theorectical Physics.
Thus and thus, the process relational system of panentheism (not pantheism, not classic theism). God sang the universes into existence. God breathed upon the "there" there and it became - and will always be becoming.   - re slater

 


What came before the Big Bang? Quantum creation.
How to get a Universe from nothing
Apr 19, 2019

Arvin Ash

Quantum Creation – what came before the big bang - the mechanism of a universe out of NO-thing - no matter, no space, and no time. Ancient Greek cosmologist Parmenides said “Nothing comes from nothing.”  He was likely referring to the law of conservation of energy, that no new energy can be created.  This is true and is a scientific fact even today. So how could the Universe come from nothing?
 
Since the discovery of quantum physics and relativity, we have discovered a flaw in this argument that allows the creation of something from truly nothing. The Universe indeed had a beginning about 13.8 billion years ago, with the Big Bang.  But what was there before the Big Bang?  How did the universe come about from nothing. The flaw that we have uncovered in Parmenides original argument of “nothing comes from nothing” is that gravity has negative energy.  And matter has positive energy.  

In a closed universe, a spontaneous splitting of 0 energy into an equal amount of positive energy and negative energy would not violate any conservation laws, because no new energy would have been created.  And in quantum mechanics, anything that is not forbidden by conservation laws has a non-zero probability of occurring.  

But then we did not start with nothing. We started with the vacuum of physics, which has virtual particles that come in and out of existence, over very short periods of time. it has a weight and can be scientifically measured. So this is not nothing.

So a more fundamental question is can a universe really be created with truly nothing – that means no-thing – no space, no matter, no time, no nothing?  To answer this question, let’s work our way back from where we are now.  

If you solve Einstein’s equations for a universe like ours, you discover that it describes a universe that is either contracting or expanding. At the beginning of the big bang, it has a finite size, below which you cannot go any smaller. How does an explosion like the big bang occur from this finite size universe? In late 1979, a Stanford physics postdoc named Alan Guth offered an explanation for this bang or explosion. He showed that using the theories in particle physics, at extremely high energies — much higher than we could ever create in a lab — a special state of matter turns gravity upside down, causing it to be repulsive rather than an attractive force.

A patch of space that contains even a tiny bit of this unusual matter, much smaller than the size of an atom, could repel itself so violently that it would blow up.  And expand to a huge size.  This would have happened for a very short time, a tiny fraction of a second, because this repulsive force quickly decays into the attractive force of gravity we see today.  But this short period of time is enough to cause the “bang” in the big bang.  
   
So now we are at the Big Bang.  We have a finite size universe with extremely high energy density that exploded in a brief inflationary period, and caused the big bang. Now, let’s go back further…the question now is how did a zero-size universe (a nothing) become Guth’s finite size universe.    

Physicist Alexander Vilenkin of Tufts University published a paper in 1984 that showed how this was possible using currently known laws of quantum mechanics. And he originated the idea of something called Quantum Creation. He showed that there is some energy barrier that the zero-size universe had to overcome in order to become finite size.  This is where a phenomenon called quantum tunneling comes into play. It turns out that there is a probability, not very large, but a non-zero probability.

Quantum tunneling is a real phenomenon that can be measured and is known to exist. Quantum mechanics shows that particles are waves of probabilities – and these waves have a non-zero probability of showing up spontaneously outside a barrier. This is how for example, an electron, or even atom, behind a barrier has a small probability of showing up on the other side of the barrier.  Our "zero-size" universe can, through the process of quantum tunneling, become a finite size universe.  

And once it does that, then Guth’s cosmic inflation occurs, triggering the Big Bang. Then Einstein’s laws take over, and the universe’s expanding journey begins. And 13.8 billion years later, we observe the universe as we do today. So quantum mechanics gets you from zero size to a finite size, and then to the Big Bang. And then general relativity can get you from there to where we are today.  

And what triggered all this? In quantum physics, events do not necessarily have a cause, just some probability. So there is some probability for the universe to pop out of “nothing. If it is true, our existence had the humblest beginning of all - from nothingness itself. But you are still not starting with nothing, because you have to start with the laws of quantum mechanics.  Where did these laws come from? [Hint: "Not from nothing."] - Arvin Ash

We actually have a pretty good idea of what might have happened before the Big Bang. That is, as long as we define the Big Bang as the extremely hot, dense, rapidly expanding universe that is described by Einstein’s equations. That picture of the universe is very solid down to about a trillionth of a second after the supposed beginning of time. We can make good guesses down to about 10^-30th of a second. But before that?

Surprise: the Big Bang isn’t the beginning of the universe anymore


The modern cosmic picture of our universe’s history begins not with a singularity that we identify with the Big Bang, but rather with a period of cosmic inflation that stretches the universe to enormous scales, with uniform properties and spatial flatness. The end of inflation signifies the onset of the hot Big Bang. (Credit: Nicole Rager Fuller/National Science Foundation)


Surprise: the Big Bang isn’t the beginning
of the universe anymore

by Ethan Siegel
October 13, 2021


We used to think the Big Bang meant the universe began from
a singularity. Nearly 100 years later, we're not so sure.


Key Takeaways

  • The Big Bang teaches us that our expanding, cooling universe used to be younger, denser, and hotter in the past.
  • However, extrapolating all the way back to a singularity leads to predictions that disagree with what we observe.
  • Instead, cosmic inflation preceded and set up the Big Bang, changing our cosmic origin story forever.

Where did all this come from? In every direction we care to observe, we find stars, galaxies, clouds of gas and dust, tenuous plasmas, and radiation spanning the gamut of wavelengths: from radio to infrared to visible light to gamma rays. No matter where or how we look at the universe, it’s full of matter and energy absolutely everywhere and at all times. And yet, it’s only natural to assume that it all came from somewhere. If you want to know the answer to the biggest question of all — the question of our cosmic origins — you have to pose the question to the universe itself, and listen to what it tells you.

Today, the universe as we see it is expanding, rarifying (getting less dense), and cooling. Although it’s tempting to simply extrapolate forward in time, when things will be even larger, less dense, and cooler, the laws of physics allow us to extrapolate backward just as easily. Long ago, the universe was smaller, denser, and hotter. How far back can we take this extrapolation? Mathematically, it’s tempting to go as far as possible: all the way back to infinitesimal sizes and infinite densities and temperatures, or what we know as a singularity. This idea, of a singular beginning to space, time, and the universe, was long known as the Big Bang.

But physically, when we looked closely enough, we found that the universe told a different story. Here’s how we know the Big Bang isn’t the beginning of the universe anymore.

Countless scientific tests of Einstein’s general theory of relativity have been performed, subjecting the idea to some of the most stringent constraints ever obtained by humanity. Einstein’s first solution was for the weak-field limit around a single mass, like the Sun; he applied these results to our Solar System with dramatic success. Very quickly, a handful of exact solutions were found thereafter. (Credit: LIGO scientific collaboration, T. Pyle, Caltech/MIT)

Like most stories in science, the origin of the Big Bang has its roots in both theoretical and experimental/observational realms. On the theory side, Einstein put forth his general theory of relativity in 1915: a novel theory of gravity that sought to overthrow Newton’s theory of universal gravitation. Although Einstein’s theory was far more intricate and complicated, it wasn’t long before the first exact solutions were found.

  • In 1916, Karl Schwarzschild found the solution for a pointlike mass, which describes a nonrotating black hole.
  • In 1917, Willem de Sitter found the solution for an empty universe with a cosmological constant, which describes an exponentially expanding universe.
  • From 1916 to 1921, the Reissner-Nordström solution, found independently by four researchers, described the spacetime for a charged, spherically symmetric mass.
  • In 1921, Edward Kasner found a solution that described a matter-and-radiation-free universe that’s anisotropic: different in different directions.
  • In 1922, Alexander Friedmann discovered the solution for an isotropic (same in all directions) and homogeneous (same at all locations) universe, where any and all types of energy, including matter and radiation, were present.

The first Friedmann equation describes all of these epochs, from inflation to the Big Bang to the present and far into the future, perfectly accurately, even today. (Credit: NASA/WMAP science team)

That last one was very compelling for two reasons. One is that it appeared to describe our universe on the largest scales, where things appear similar, on average, everywhere and in all directions. And two, if you solved the governing equations for this solution — the Friedmann equations — you’d find that the universe it describes cannot be static, but must either expand or contract.

This latter fact was recognized by many, including Einstein, but it wasn’t taken particularly seriously until the observational evidence began to support it. In the 1910s, astronomer Vesto Slipher started observing certain nebulae, which some argued might be galaxies outside of our Milky Way, and found that they were moving fast: far faster than any other objects within our galaxy. Moreover, the majority of them were moving away from us, with fainter, smaller nebulae generally appearing to move faster.

Then, in the 1920s, Edwin Hubble began measuring individual stars in these nebulae and eventually determined the distances to them. Not only were they much farther away than anything else in the galaxy, but the ones at the greater distances were moving away faster than the closer ones. As Lemaître, Robertson, Hubble, and others swiftly put together, the universe was expanding.

Edwin Hubble’s original plot of galaxy distances versus redshift (left), establishing the expanding universe, versus a more modern counterpart from approximately 70 years later (right). In agreement with both observation and theory, the universe is expanding. (Credit: E. Hubble; R. Kirshner, PNAS, 2004)

Georges Lemaître was the first, in 1927, to recognize this. Upon discovering the expansion, he extrapolated backward, theorizing — as any competent mathematician might — that you could go as far back as you wanted: to what he called the primeval atom. In the beginning, he realized, the universe was a hot, dense, and rapidly expanding collection of matter and radiation, and everything around us emerged from this primordial state.

This idea was later developed by others to make a set of additional predictions:

  • The universe, as we see it today, is more evolved than it was in the past. The farther back we look in space, the farther back we’re also looking in time. So, the objects we see back then should be younger, less gravitationally clumpy, less massive, with fewer heavy elements, and with less-evolved structure. There should even be a point beyond which no stars or galaxies were present.
  • At some point, the radiation was so hot that neutral atoms couldn’t stably form, because radiation would reliably kick any electrons off of the nuclei they were attempting to bind to, and so there should be a leftover — now cold and sparse — bath of cosmic radiation from this time.
  • At some extremely early time it would have been so hot that even atomic nuclei would be blasted apart, implying there was an early, pre-stellar phase where nuclear fusion would have occurred: Big Bang nucleosynthesis. From that, we expect there to have been at least a population of light elements and their isotopes spread throughout the universe before any stars formed.

A visual history of the expanding universe includes the hot, dense state known as the Big Bang and the growth and formation of structure subsequently. The full suite of data, including the observations of the light elements and the cosmic microwave background, leaves only the Big Bang as a valid explanation for all we see. (Credit: NASA/CXC/M. Weiss)

In conjunction with the expanding universe, these four points would become the cornerstone of the Big Bang. The growth and evolution of the large-scale structure of the universe, of individual galaxies, and of the stellar populations found within those galaxies all validates the Big Bang’s predictions. The discovery of a bath of radiation just ~3 K above absolute zero — combined with its blackbody spectrum and temperature imperfections at microkelvin levels of tens to hundreds — was the key evidence that validated the Big Bang and eliminated many of its most popular alternatives. And the discovery and measurement of the light elements and their ratios — including hydrogen, deuterium, helium-3, helium-4, and lithium-7 — revealed not only which type of nuclear fusion occurred prior to the formation of stars, but also the total amount of normal matter that exists in the universe.

Extrapolating back to as far as your evidence can take you is a tremendous success for science. The physics that took place during the earliest stages of the hot Big Bang imprinted itself onto the universe, enabling us to test our models, theories, and understanding of the universe from that time. The earliest observable imprint, in fact, is the cosmic neutrino background, whose effects show up in both the cosmic microwave background (the Big Bang’s leftover radiation) and the universe’s large-scale structure. This neutrino background comes to us, remarkably, from just ~1 second into the hot Big Bang.

If there were no oscillations due to matter interacting with radiation in the universe, there would be no scale-dependent wiggles seen in galaxy clustering. The wiggles themselves, shown with the non-wiggly part subtracted out (bottom), is dependent on the impact of the cosmic neutrinos theorized to be present by the Big Bang. Standard Big Bang cosmology corresponds to β=1. (Credit: D. Baumann et al., Nature Physics, 2019)

But extrapolating beyond the limits of your measurable evidence is a dangerous, albeit tempting, game to play. After all, if we can trace the hot Big Bang back some 13.8 billion years, all the way to when the universe was less than 1 second old, what’s the harm in going all the way back just one additional second: to the singularity predicted to exist when the universe was 0 seconds old?

The answer, surprisingly, is that there’s a tremendous amount of harm — if you’re like me in considering “making unfounded, incorrect assumptions about reality” to be harmful. The reason this is problematic is because beginning at a singularity — at arbitrarily high temperatures, arbitrarily high densities, and arbitrarily small volumes — will have consequences for our universe that aren’t necessarily supported by observations.

For example, if the universe began from a singularity, then it must have sprung into existence with exactly the right balance of “stuff” in it — matter and energy combined — to precisely balance the expansion rate. If there were just a tiny bit more matter, the initially expanding universe would have already recollapsed by now. And if there were a tiny bit less, things would have expanded so quickly that the universe would be much larger than it is today.

If the universe had just a slightly higher density (red), it would have recollapsed already; if it had just a slightly lower density, it would have expanded much faster and become much larger. The Big Bang, on its own, offers no explanation as to why the initial expansion rate at the moment of the universe’s birth balances the total energy density so perfectly, leaving no room for spatial curvature at all. (Credit: Ned Wright’s cosmology tutorial)

And yet, instead, what we’re observing is that the universe’s initial expansion rate and the total amount of matter and energy within it balance as perfectly as we can measure.

Why?

If the Big Bang began from a singularity, we have no explanation; we simply have to assert “the universe was born this way,” or, as physicists ignorant of Lady Gaga call it, “initial conditions.”

Similarly, a universe that reached arbitrarily high temperatures would be expected to possess leftover high-energy relics, like magnetic monopoles, but we don’t observe any. The universe would also be expected to be different temperatures in regions that are causally disconnected from one another — i.e., are in opposite directions in space at our observational limits — and yet the universe is observed to have equal temperatures everywhere to 99.99%+ precision.

We’re always free to appeal to initial conditions as the explanation for anything, and say, “well, the universe was born this way, and that’s that.” But we’re always far more interested, as scientists, if we can come up with an explanation for the properties we observe.

In the top panel, our modern universe has the same properties (including temperature) everywhere because they originated from a region possessing the same properties. In the middle panel, the space that could have had any arbitrary curvature is inflated to the point where we cannot observe any curvature today, solving the flatness problem. And in the bottom panel, pre-existing high-energy relics are inflated away, providing a solution to the high-energy relic problem. This is how inflation solves the three great puzzles that the Big Bang cannot account for on its own. (Credit: E. Siegel/Beyond the Galaxy)

That’s precisely what cosmic inflation gives us, plus more. Inflation says, sure, extrapolate the hot Big Bang back to a very early, very hot, very dense, very uniform state, but stop yourself before you go all the way back to a singularity. If you want the universe to have the expansion rate and the total amount of matter and energy in it balance, you’ll need some way to set it up in that fashion. The same applies for a universe with the same temperatures everywhere. On a slightly different note, if you want to avoid high-energy relics, you need some way to both get rid of any preexisting ones, and then avoid creating new ones by forbidding your universe from getting too hot once again.

Inflation accomplishes this by postulating a period, prior to the hot Big Bang, where the universe was dominated by a large cosmological constant (or something that behaves similarly): the same solution found by de Sitter way back in 1917. This phase stretches the universe flat, gives it the same properties everywhere, gets rid of any pre-existing high-energy relics, and prevents us from generating new ones by capping the maximum temperature reached after inflation ends and the hot Big Bang ensues. Furthermore, by assuming there were quantum fluctuations generated and stretched across the universe during inflation, it makes new predictions for what types of imperfections the universe would begin with.

The quantum fluctuations that occur during inflation get stretched across the universe, and when inflation ends, they become density fluctuations. This leads, over time, to the large-scale structure in the universe today, as well as the fluctuations in temperature observed in the CMB. New predictions like these are essential for demonstrating the validity of a proposed fine-tuning mechanism. (Credit: E. Siegel; ESA/Planck and the DOE/NASA/NSF Interagency Task Force on CMB research)

Since it was hypothesized back in the 1980s, inflation has been tested in a variety of ways against the alternative: a universe that began from a singularity. When we stack up the scorecard, we find the following:

  • Inflation reproduces all of the successes of the hot Big Bang; there’s nothing that the hot Big Bang accounts for that inflation can’t also account for.
  • Inflation offers successful explanations for the puzzles that we simply have to say “initial conditions” for in the hot Big Bang.
  • Of the predictions where inflation and a hot Big Bang without inflation differ, four of them have been tested to sufficient precision to discriminate between the two. On those four fronts, inflation is 4-for-4, while the hot Big Bang is 0-for-4.

But things get really interesting if we look back at our idea of “the beginning.” Whereas a universe with matter and/or radiation — what we get with the hot Big Bang — can always be extrapolated back to a singularity, an inflationary universe cannot. Due to its exponential nature, even if you run the clock back an infinite amount of time, space will only approach infinitesimal sizes and infinite temperatures and densities; it will never reach it. This means, rather than inevitably leading to a singularity, inflation absolutely cannot get you to one by itself. The idea that “the universe began from a singularity, and that’s what the Big Bang was,” needed to be jettisoned the moment we recognized that an inflationary phase preceded the hot, dense, and matter-and-radiation-filled one we inhabit today.


Blue and red lines represent a “traditional” Big Bang scenario, where everything starts at time t=0, including spacetime itself. But in an inflationary scenario (yellow), we never reach a singularity, where space goes to a singular state; instead, it can only get arbitrarily small in the past, while time continues to go backwards forever. Only the last minuscule fraction of a second, from the end of inflation, imprints itself on our observable universe today. (Credit: E. Siegel)

This new picture gives us three important pieces of information about the beginning of the universe that run counter to the traditional story that most of us learned. First, the original notion of the hot Big Bang, where the universe emerged from an infinitely hot, dense, and small singularity — and has been expanding and cooling, full of matter and radiation ever since — is incorrect. The picture is still largely correct, but there’s a cutoff to how far back in time we can extrapolate it.

Second, observations have well established the state that occurred prior to the hot Big Bang: cosmic inflation. Before the hot Big Bang, the early universe underwent a phase of exponential growth, where any preexisting components to the universe were literally “inflated away.” When inflation ended, the universe reheated to a high, but not arbitrarily high, temperature, giving us the hot, dense, and expanding universe that grew into what we inhabit today.

Lastly, and perhaps most importantly, we can no longer speak with any sort of knowledge or confidence as to how — or even whether — the universe itself began. By the very nature of inflation, it wipes out any information that came before the final few moments: where it ended and gave rise to our hot Big Bang. Inflation could have gone on for an eternity, it could have been preceded by some other nonsingular phase, or it could have been preceded by a phase that did emerge from a singularity. Until the day comes where we discover how to extract more information from the universe than presently seems possible, we have no choice but to face our ignorance. The Big Bang still happened a very long time ago, but it wasn’t the beginning we once supposed it to be.


Love is the center of all bible readings and doctrines

 


Literal, grammatical, historical, contextual... all good approaches except one. Drop the literal reading of the bible where we read our belief sets, cultural mores, and prejudices into the bible. It misinforms and leads to bad theology.

But the last three approaches well informs the Hebraic or Greek Hellenistic beliefs of that day. Not so the literal reading of those ancient cultures.

Which means a good hermenuetic is redactive to the text per the rules (beliefs) of those ancient societal eras.

Which is also why theology is so full of interpretive meanings for different sects and denominations.

The best hermenuetic I have found is this:

"God is love regardless of what religious man thought of God in the OT and NT."

To underscore my point, the Abrahamic Covenant is the same as the New Covenant. God sacrifices Himself in order to enforce and assure His covenant with mankind through Abraham (saved by faith as response to divine act) and later at the Cross through Christ in the New Covenant.

In sum, the best hermenuetic is "Love = Jesus". Put it at the center of all bible readings and not the "bible" per se.

God's Love informs our reading, our faith, our doctrines, our judgments, our actions, our responses, and our worship. Putting any other doctrine in the center removes Love, making God something other than He is.

Richard Feynman. Why.
Apr 2, 2012




“I can live with doubt and uncertainty and not knowing. I think it is much more interesting to live not knowing than to have answers that might be wrong. If we will only allow that, as we progress, we remain unsure, we will leave opportunities for alternatives. We will not become enthusiastic for the fact, the knowledge, the absolute truth of the day, but remain always uncertain … In order to make progress, one must leave the door to the unknown ajar.” ― Richard P. Feynman

“So I have just one wish for you – the good luck to be somewhere where you are free to maintain the kind of integrity I have described, and where you do not feel forced by a need to maintain your position in the organization, or financial support, or so on, to lose your integrity. May you have that freedom.” ― Richard P. Feynman Surely You're Joking, Mr. Feynman!: Adventures of a Curious Character

“You have no responsibility to live up to what other people think you ought to accomplish. I have no responsibility to be like they expect me to be. It's their mistake, not my failing.” ― Richard P. Feynman, Surely You're Joking, Mr. Feynman!: Adventures of a Curious Character

“Physics is like sex: sure, it may give some practical results, but that's not why we do it.”

“I have a friend who's an artist and has sometimes taken a view which I don't agree with very well. He'll hold up a flower and say "look how beautiful it is," and I'll agree. Then he says "I as an artist can see how beautiful this is but you as a scientist take this all apart and it becomes a dull thing," and I think that he's kind of nutty. First of all, the beauty that he sees is available to other people and to me too, I believe. Although I may not be quite as refined aesthetically as he is ... I can appreciate the beauty of a flower. At the same time, I see much more about the flower than he sees. I could imagine the cells in there, the complicated actions inside, which also have a beauty. I mean it's not just beauty at this dimension, at one centimeter; there's also beauty at smaller dimensions, the inner structure, also the processes. The fact that the colors in the flower evolved in order to attract insects to pollinate it is interesting; it means that insects can see the color. It adds a question: does this aesthetic sense also exist in the lower forms? Why is it aesthetic? All kinds of interesting questions which the science knowledge only adds to the excitement, the mystery and the awe of a flower. It only adds. I don't understand how it subtracts.”  Richard P. Feynman, The Pleasure of Finding Things Out: The Best Short Works of Richard P. Feynman

“Fall in love with some activity, and do it! Nobody ever figures out what life is all about, and it doesn't matter. Explore the world. Nearly everything is really interesting if you go into it deeply enough. Work as hard and as much as you want to on the things you like to do the best. Don't think about what you want to be, but what you want to do. Keep up some kind of a minimum with other things so that society doesn't stop you from doing anything at all.” ― Richard P. Feynman

---

“I think it's much more interesting to live not knowing than to have answers which might be wrong. I have approximate answers and possible beliefs and different degrees of uncertainty about different things, but I am not absolutely sure of anything and there are many things I don't know anything about, such as whether it means anything to ask why we're here. I don't have to know an answer. I don't feel frightened not knowing things, by being lost in a mysterious universe without any purpose, which is the way it really is as far as I can tell.”  Richard P. Feynman

“I'm smart enough to know that I'm dumb.”  Richard Feynman

“You can know the name of a bird in all the languages of the world, but when you're finished, you'll know absolutely nothing whatever about the bird... So let's look at the bird and see what it's doing — that's what counts. I learned very early the difference between knowing the name of something and knowing something.”  Richard P. Feynman, "What Do You Care What Other People Think?": Further Adventures of a Curious Character

“A poet once said, 'The whole universe is in a glass of wine.' We will probably never know in what sense he meant it, for poets do not write to be understood. But it is true that if we look at a glass of wine closely enough we see the entire universe. There are the things of physics: the twisting liquid which evaporates depending on the wind and weather, the reflection in the glass; and our imagination adds atoms. The glass is a distillation of the earth's rocks, and in its composition we see the secrets of the universe's age, and the evolution of stars. What strange array of chemicals are in the wine? How did they come to be? There are the ferments, the enzymes, the substrates, and the products. There in wine is found the great generalization; all life is fermentation. Nobody can discover the chemistry of wine without discovering, as did Louis Pasteur, the cause of much disease. How vivid is the claret, pressing its existence into the consciousness that watches it! If our small minds, for some convenience, divide this glass of wine, this universe, into parts -- physics, biology, geology, astronomy, psychology, and so on -- remember that nature does not know it! So let us put it all back together, not forgetting ultimately what it is for. Let it give us one more final pleasure; drink it and forget it all!”

“What I am going to tell you about is what we teach our physics students in the third or fourth year of graduate school... It is my task to convince you not to turn away because you don't understand it. You see my physics students don't understand it... That is because I don't understand it. Nobody does.”  Richard P. Feynman,  QED: The Strange Theory of Light and Matter

“Poets say science takes away from the beauty of the stars - mere globs of gas atoms. I too can see the stars on a desert night, and feel them. But do I see less or more? The vastness of the heavens stretches my imagination - stuck on this carousel my little eye can catch one - million - year - old light. A vast pattern - of which I am a part... What is the pattern, or the meaning, or the why? It does not do harm to the mystery to know a little about it. For far more marvelous is the truth than any artists of the past imagined it. Why do the poets of the present not speak of it? What men are poets who can speak of Jupiter if he were a man, but if he is an immense spinning sphere of methane and ammonia must be silent?”  Richard Feynman

---

“It doesn't seem to me that this fantastically marvelous universe, this tremendous range of time and space and different kinds of animals, and all the different planets, and all these atoms with all their motions, and so on, all this complicated thing can merely be a stage so that God can watch human beings struggle for good and evil - which is the view that religion has. The stage is too big for the drama.”  Richard P. Feynman

“There are 10^11 stars in the galaxy. That used to be a huge number. But it's only a hundred billion. It's less than the national deficit! We used to call them astronomical numbers. Now we should call them economical numbers.”  Richard Feynman

“I don't know what's the matter with people: they don't learn by understanding, they learn by some other way — by rote or something. Their knowledge is so fragile!”  Richard Feynman
