I might recommend that you try “physics with Witten“ which is Edward Whittens lessons of which there are 22 each about an hour and a half long that he conducts at Princeton. I have listened to all 22 at one time or another and although I can’t understand 95% of what he’s teaching, there’s a pattern and a rhythm and a soothing quality which Aids in my insomnia. Peace. P

The style in which Dr. Greene interviews is amazing. He should do a Masterclass on that. Allowing the interviewee time to explain and postulate while simultaneously adding his own perspective and segueing into new topics makes it so smooth and an easy listening experience.
Greetings from Germany. I strongly believe, that when Sir Martin Rees was born, the nurses looked at him and said „ this one is going to be someone big, very big“. They were right. THE gentleman scientist of our age. Weiter so, Sir Martin!
This is the greatest discussion I've seen with Greene. And literally the only one where I didn't feel like he was ahead of the conversation at all times. Martin Rees is truly an extraordinary mind. I have a feeling I'll be coming back to it periodically for a long time.
Mr. Green and Mr. Rees this was an incredible show and it was very informative for the non-science degree individual to understand. In the scientific world we are constantly learning and understanding and things will changes as we learn and continue to understand things. I love WSF and thank you for some great streaming this allows an old former US Army soldier who earned a degree in chemistry geek out and think about the universe and the heavens.
And if you do, you might realize how pointless the answers to these questions can be on many aspects... IF every question asked here was answered, ask yourself "What difference would it make to you, me, or even humanity as a whole right NOW. -- Would any answers to their questions fix humanity? Would it fix the russian conflict? The palestine conflict? Inflation? Hunger? Absolutely NOT.
@@250txc I really shouldn't respond to this because it isn't worth the energy. The answers are interesting to me, and therefore are not pointless.

We are the ones who hold the secrets of the Cosmos. It is our duty to make sure that knowledge is never lost, and that it is preserved for the future of us, and any others out there in the Universe. I am now 68 years old, and in my single lifetime hundreds of basic facts about all the sciences has bloomed. To go from Hubble's discovery to the JWST's amazing discoveries is profound. I do not regret one penny of funding for these ventures. We are better people who can use science to further our world's future.

chatGPT: "The mass of the electron is a fundamental constant known as the "electron rest mass." It is one of the most important and well-known parameters in physics, particularly in atomic and quantum physics. The electron rest mass is approximately: 9.109×10−319.109×10−31 kilograms (kg) or equivalently, 0.510998950.51099895 mega-electronvolts (MeV/c²) (where "c" is the speed of light, and MeV stands for mega-electronvolts, a common energy unit in particle physics). This value represents the mass of a stationary electron and is a crucial part of various fundamental equations in physics, including Schrödinger's equation for quantum mechanics and the relativistic energy-mass equivalence principle E=mc2E=mc2."
Thank you for making this timely piece. It really helps clarify the confusing messages we've been hearing/reading recently due to the release of new data from the JWT
Greene and Rees say that the hotter regions in the CMB indicate higher density, but don't explain why. I asked chatgpt. Their answer: In regions of the early universe that were denser, there were more particles (like protons, electrons, and photons) present. This increased density meant that there were more interactions (like scattering) between particles, which led to slightly hotter temperatures. So, the hotter spots in the CMB map correspond to regions where there was a higher concentration of matter.
It's also why the he mentioned it informs the structure of the universe, the higher density areas correlate to cosmic strings, attractors of matter that form largest concentrations of matter we can identify.
Super discussion; wish they had embraced longevity escape velocity, and the likelihood of enhancing our mental capacity via genetics/engineering/medical tech, and thereby understanding things beyond what evolution has let our brains conceive.
As for dark matter I just watched a talk from Neil Turok at Perimeter that suggests dark matter may be right handed neutrinos. His idea also does away with inflation, is consistent with Lambda CDM, and has an interesting idea about the Big Bang singularity. At least seems to anyway.

Listening to this excellent talk, I get the impression that we are living within a certain bandwidth of modulation on a spatial carrier that modulates waves with spacial frequencies varrying between stationary and the speed of light. At the lower limit, we can probe the inner perceived magic described by quantum mechanics. The shadow that this world casts until our modulated reality, cones in the form of a spread of identical particles, that may have connection with each other at a distance as perceived by us, but local in a reality that is outside of our bandwidth. So, there is a universe on its own, captured like a hologram in identical particles that differ only with phase (like real holograms). On the cosmic scales, the shadow of parallel reality presents itself as Big Bang, black holes, spacial accelerating expansion in scale (vaguely referred to as dark energy) and dark matter. I feel we may be able to connect these 3 real parallel universes and figure out what the extra spatial dimension looks like that expands our cosmic reality, mystify our sub-atomic reality as described by our quantum Physics gestimation model. My question: is there research to probe individual electrons on information carried within about phase in relation to other individual electrons? Similarly, is there study ongoing that searches fir links of how the hidden dimension at larger scales (speed c < parallel reality < c2.
We should look at new worlds that cast their shadow as described by QM ánd that cast there other unique shadow on our reality as described by GR. The unification of QM and GR goes via parallel universes, beyond our direct horizons. Fields are patterns of these realities.
We often talk about the ‘early universe’ as if we still aren’t in it. According to most accepted cosmology models the current Universe isn’t even one octillionth of its eventual age or size. The Universe isn’t big but absurdly small. The odds of being at this stage along the continuum is even more absurd.
What was the Maths that proved out in the graph? I'd really like to know what we're the numbers put in to give us the "holy grail"! Thank you both as always inspiring and easy to follow.
On the A.I. discussion at roughly 35:00, it seems to me that we already at the point of not understanding how the A.I. models we have work (not completely completely), and we use those incompletely understood A.I. models to develop new, better and even more complex A.I. models. Add to that, what we call "A.I." is not actually intelligence yet. They are just complicated algorithms. Real artificial intelligence is likely coming and it will both help us answer questions we want answered and answer questions it comes up with on its own (and we may not even understand the questions these future intelligences are asking ). We have to be prepared for that. Someday the smartest and best educated of us will still be like chimpanzees staring at a machine that dispenses bananas. We will only know the bananas are good, not how the machine is producing them. The creations of our creations will be engaged in what, to us, will look like magic at that point.
Why would an intelligence that could view us simple chimpanzees happy with the bananas it dispenses to us, continue to dispense those bananas? Presumably, if the chimps are some how required for the future success of the "magic" AI then it ensure that bananas are forever forth-coming, but that seems even more far-fetched than an intelligence that considers humans as chimnpanzees who need bananas regularly. Magic-level AI would have dispensed with feeding humans bananas a long time ago, surely?
Thank you for this talk. One remark: When you talk from the size of our universe of a solar system or a tennis ball, you mean for sure the size of our visible universe, right? As we know so far the universe is and was infinite since the big bang.
Hello Sir.. I was thinking that 'since Sun is one of the foci of the planetary orbits, maybe the other foci is occupied by antimatter of Sun'.. Could it be possible?
I think in the future, computers will be so powerful, they will be able to work out the universe mathematically. With human experimental data fed to them as biofeedback. They TEACH us how the mechanisms of the universe work. They do the calculations, and break it down for us. Just as science communicators do to regular people.
Yes! Pattern recognition is it all there is. Pattern recognition is logic, science, philosophy, theology, is it all there is. Heres the thing. There're two realities. One is Truth, the ultimate truthor reality. The other is a practical realistic reality. Truth, we can never be sure if or when we get it. We may get to ir but never be for 100% sure. That's because of our soliscism, consciousness in brain through 5 biological senses, everything can be a figment of your imagination (consciousness). And so let's assume there's the real world out there, and we do sense it, experience it, the practical realistic reality. Although ultimately it always comes down to solitudcism. In science terms, it's a special relativity and quantum mechanics.😊 Ok, so we see patterns. We see patterns in patterns and patterns in patterns. We try to figure out the order of patterns and their causalities, what causing what to make it a pattern. And we apply them, follow them. If we're right, we could figure out its outcomes. We can plan it ahead. We could plan the future following the patterns. But at the end of the day we do have to make a choice. To make a choice, we'd have to evaluate available choices. So how do we evaluate? I think that's where our biological feelings come on. There're two sort of feelings, physical feelings like pains when there's a cut or punched or burned or something. And feelings of physical pleasure, sexual ones or scratching an itch or something. And there're meta-physcal or phycological feelings like feeling happy, sad, sorrow, anger, fear, etc. Or something between like feeling thirsty or hungry or tired or ... I've no idea how or what our brains work in those things, though. But i think we see patterns, figure out the order of the patterns and try to understand their causalities, and we apply them and follow them to make a choice for our future actions. Sonething like that, i think, maybe, maybe not. Something my useless nonsensical wonderings.😂
I asked chatgpt how to predict the mass of the electron. It replied "If there were a fundamental theory that accurately predicted the electron mass without experimental input, it would be a groundbreaking discovery and could lead to significant advancements in our understanding of physics. As of my last knowledge update in January 2022, no such theory existed."
When they discuss giving up privacy they implicitly assume that surveillance would be done by a benevolent authority. However, once you build systems that allow surveillance then there is no control on who would exploit that. Then, an adversary can use surveillance to find those who would make a bio weapon and encourage them to make them!
It isn't much different for me than the trust we put in our policing systems. They are done "by consent" and are deeply flawed in practise. The oversight of policing is woefully inadequate and the punishment for failure is,due to corruption of humanity, failing to correct the issues. However, those policing failures are critical for the individuals involved, often fatal, but don't scale up to large populations, thankfully, yet. That's not to be certain that the future of policing cannot be made, on purpose or accidentally, to a scale that endangers the majority or all of the populance. Who watches the watcher is a long asked question and is, clearly, fundamental to a system as future pervasive as something like AI will almost certainly become. Who, and how to control, manage and protect is vitally important. Government oversight? Well, that doesn't work on so many levels already with systems that are not all encompassing (re:policing as described). Systems that monitor systems? Chicken and egg situation, who manages, control and protects the systems that monitor the systems, ad naseum? We can be hopeful, there is "hope" in "hopeless" afterall. But it would be naive to believe that we, as flawed humans, have capabilities to control the future safety and security of AI, in particular, and other dangers, Bio weapons, etc. Sure, we can give up our privacy for a guaranteed safety - I'd be happy with that. But who/what can provide that guarantee? Sorry, got no answer, except to say I WILL NOT GIVE UP MY PRIVACY TO ANY SYSTEM THAT IS ADMINSTERED BY GOVERNMENT OR CORPORATION ( don't leave much, huh?)
Brian, what the hell was going on in the background at the beginning of the talk? It looks like a couple people walked onto a plank on a construction site, and through a few things over. They keep going away, and coming back.
The talk about the future was eye opening. We humans have evolved in various ways and at various speeds. Our ability to live peacefully and sustainably lags almost logarithmically versus our ability to alter the planet and develop technology. Our vast population, 8.1 billion with our dependence on cities and industrial farming means most of us would have no idea how to live like our ancestors. Many good things. Much lost.
I always thought if the Big Bang existed we would show the galaxies far way would be closer to where the point of explosion occurred, but what we have found seems to be a universe which was already expanded beyond where we are at the beginning of our ability to see galaxies. So we came of with a new theory. The main reason for this theory seems to be so we could keep the Big Bang theory. Now we theorize the expansion is increasing? So there was a very fast expansion, then everything slowed so we could see what we see, then expansion is increasing again. I don't think we need to throw away what we have done, but we need to refine our measurements and be open to a new theory if it fits all the hard points.
Yep, as the comment above said: the big bang didn’t occur at a single place. It occurred “everywhere”. We know space is expanding, but it’s not expanding in one direction from a source to a destination (I suspect many people mistakenly view the known Universe as a sphere, with the big bang in the centre - this is actually mistaken). It’s more accurate to imagine the space between all objects expanding in all directions simultaneously. Also, technically speaking, we only know that the early Universe was very hot and dense. At a certain point, known physics break down. The label we use to describe the point beyond is “big bang”. However, technically, we don’t know what the Universe’s initial conditions were. It may be, for example, that there was never a “beginning” in the way we intuitively understand it. It could be (as Penrose suggests), that the Universe periodically expands and then contracts and expands again - perhaps forever and ever. Also, some theories suggest that space and time themselves are emergent properties and are not fundamental to reality. As humans, we experience the arrow of time. It is plausible that we are trapped by our experience of time and are unable to access its true nature. As a result, even positing a “beginning” of the Universe could be highly erroneous - it may be “the wrong question”, as some say.
Hi Brian, what about the cosmological constant ? Is anything confirmed other than the standard model the higs boson ? For the rest nothing has happened for the moment. The Guth inflation theory is put in question ! SWT has shown confiquring galaxies much more earlier than the inflationary model , much more older than supposed., nothtig to do with te mass of the electron.. Not the system of the inflationary model, is in question, only iI supposes a little bit older. But we have the Linda’s theorem ? Multiverse/fine tuning/strings ? For me the plausible outcomes are curled up strings (how dimensions I don’t know) its for the moment the most obvious. Other than de Sitter Space as the Plank length, holographical prinipal. Collision of branes JWST has demonstrated a very big void 1.8 bilions LY across. Which can concure with string tjheory, as branes
as a layman i feel that dark energy and dark matter may have all the solutions to all the queries of expanding universe dark hole gravity formation of universe

Listening to this excellent talk, I get the impression that we are living within a certain bandwidth of modulation on a spatial carrier that modulates waves with spacial frequencies varrying between stationary and the speed of light. At the lower limit, we can probe the inner perceived magic described by quantum mechanics. The shadow that this world casts until our modulated reality, cones in the form of a spread of identical particles, that may have connection with each other at a distance as perceived by us, but local in a reality that is outside of our bandwidth.
So, there is a universe on its own, captured like a hologram in identical particles that differ only with phase (like real holograms).
On the cosmic scales, the shadow of parallel reality presents itself as Big Bang, black holes, spacial accelerating expansion in scale (vaguely referred to as dark energy) and dark matter. I feel we may be able to connect these 3 real parallel universes and figure out what the extra spatial dimension looks like that expands our cosmic reality, mystify our sub-atomic reality as described by our quantum Physics gestimation model.
My question: is there research to probe individual electrons on information carried within about phase in relation to other individual electrons? Similarly, is there study ongoing that searches fir links of how the hidden dimension at larger scales (speed c < parallel reality < c2.
We should look at new worlds that cast their shadow as described by QM ánd that cast there other unique shadow on our reality as described by GR.
The unification of QM and GR goes via parallel universes, beyond our direct horizons. Fields are patterns of these realities.
We often talk about the ‘early universe’ as if we still aren’t in it. According to most accepted cosmology models the current Universe isn’t even one octillionth of its eventual age or size. The Universe isn’t big but absurdly small. The odds of being at this stage along the continuum is even more absurd.
I get what you're saying but that's not what he's saying... early relative to where we are now, so, no, we're not in the early universe.
Imagine the odds against this conversation. Enjoy the ride :)
What was the Maths that proved out in the graph? I'd really like to know what we're the numbers put in to give us the "holy grail"!
Thank you both as always inspiring and easy to follow.
35:07 The answer is 42... but we don't _understand_ the question...
On the A.I. discussion at roughly 35:00, it seems to me that we already at the point of not understanding how the A.I. models we have work (not completely completely), and we use those incompletely understood A.I. models to develop new, better and even more complex A.I. models. Add to that, what we call "A.I." is not actually intelligence yet. They are just complicated algorithms. Real artificial intelligence is likely coming and it will both help us answer questions we want answered and answer questions it comes up with on its own (and we may not even understand the questions these future intelligences are asking ). We have to be prepared for that. Someday the smartest and best educated of us will still be like chimpanzees staring at a machine that dispenses bananas. We will only know the bananas are good, not how the machine is producing them. The creations of our creations will be engaged in what, to us, will look like magic at that point.
Why would an intelligence that could view us simple chimpanzees happy with the bananas it dispenses to us, continue to dispense those bananas? Presumably, if the chimps are some how required for the future success of the "magic" AI then it ensure that bananas are forever forth-coming, but that seems even more far-fetched than an intelligence that considers humans as chimnpanzees who need bananas regularly. Magic-level AI would have dispensed with feeding humans bananas a long time ago, surely?
That looks like Grant's Tomb out the window. Anyone know what that building is?
Could the phrase, "World without End" from the English Book of Prayer allude to the idea that there is no end to the universe?

Thank you for this talk. One remark: When you talk from the size of our universe of a solar system or a tennis ball, you mean for sure the size of our visible universe, right? As we know so far the universe is and was infinite since the big bang.
Hello Sir.. I was thinking that 'since Sun is one of the foci of the planetary orbits, maybe the other foci is occupied by antimatter of Sun'.. Could it be possible?
I think in the future, computers will be so powerful, they will be able to work out the universe mathematically. With human experimental data fed to them as biofeedback. They TEACH us how the mechanisms of the universe work. They do the calculations, and break it down for us. Just as science communicators do to regular people.
Yes! Pattern recognition is it all there is. Pattern recognition is logic, science, philosophy, theology, is it all there is.
Heres the thing. There're two realities. One is Truth, the ultimate truthor reality. The other is a practical realistic reality. Truth, we can never be sure if or when we get it. We may get to ir but never be for 100% sure. That's because of our soliscism, consciousness in brain through 5 biological senses, everything can be a figment of your imagination (consciousness). And so let's assume there's the real world out there, and we do sense it, experience it, the practical realistic reality. Although ultimately it always comes down to solitudcism. In science terms, it's a special relativity and quantum mechanics.😊
Ok, so we see patterns. We see patterns in patterns and patterns in patterns. We try to figure out the order of patterns and their causalities, what causing what to make it a pattern. And we apply them, follow them. If we're right, we could figure out its outcomes. We can plan it ahead. We could plan the future following the patterns. But at the end of the day we do have to make a choice. To make a choice, we'd have to evaluate available choices. So how do we evaluate? I think that's where our biological feelings come on.
There're two sort of feelings, physical feelings like pains when there's a cut or punched or burned or something. And feelings of physical pleasure, sexual ones or scratching an itch or something. And there're meta-physcal or phycological feelings like feeling happy, sad, sorrow, anger, fear, etc. Or something between like feeling thirsty or hungry or tired or ... I've no idea how or what our brains work in those things, though. But i think we see patterns, figure out the order of the patterns and try to understand their causalities, and we apply them and follow them to make a choice for our future actions. Sonething like that, i think, maybe, maybe not. Something my useless nonsensical wonderings.😂
I asked chatgpt how to predict the mass of the electron. It replied "If there were a fundamental theory that accurately predicted the electron mass without experimental input, it would be a groundbreaking discovery and could lead to significant advancements in our understanding of physics. As of my last knowledge update in January 2022, no such theory existed."
momentum. Wha starting a hart?
Waht happen with the live with the dr . Juan maldacena?
When they discuss giving up privacy they implicitly assume that surveillance would be done by a benevolent authority. However, once you build systems that allow surveillance then there is no control on who would exploit that. Then, an adversary can use surveillance to find those who would make a bio weapon and encourage them to make them!
It isn't much different for me than the trust we put in our policing systems. They are done "by consent" and are deeply flawed in practise. The oversight of policing is woefully inadequate and the punishment for failure is,due to corruption of humanity, failing to correct the issues. However, those policing failures are critical for the individuals involved, often fatal, but don't scale up to large populations, thankfully, yet. That's not to be certain that the future of policing cannot be made, on purpose or accidentally, to a scale that endangers the majority or all of the populance.
Who watches the watcher is a long asked question and is, clearly, fundamental to a system as future pervasive as something like AI will almost certainly become. Who, and how to control, manage and protect is vitally important. Government oversight? Well, that doesn't work on so many levels already with systems that are not all encompassing (re:policing as described). Systems that monitor systems? Chicken and egg situation, who manages, control and protects the systems that monitor the systems, ad naseum?
We can be hopeful, there is "hope" in "hopeless" afterall. But it would be naive to believe that we, as flawed humans, have capabilities to control the future safety and security of AI, in particular, and other dangers, Bio weapons, etc. Sure, we can give up our privacy for a guaranteed safety - I'd be happy with that. But who/what can provide that guarantee? Sorry, got no answer, except to say I WILL NOT GIVE UP MY PRIVACY TO ANY SYSTEM THAT IS ADMINSTERED BY GOVERNMENT OR CORPORATION ( don't leave much, huh?)
Brian, what the hell was going on in the background at the beginning of the talk? It looks like a couple people walked onto a plank on a construction site, and through a few things over. They keep going away, and coming back.
The talk about the future was eye opening. We humans have evolved in various ways and at various speeds. Our ability to live peacefully and sustainably lags almost logarithmically versus our ability to alter the planet and develop technology. Our vast population, 8.1 billion with our dependence on cities and industrial farming means most of us would have no idea how to live like our ancestors. Many good things. Much lost.
I always thought if the Big Bang existed we would show the galaxies far way would be closer to where the point of explosion occurred, but what we have found seems to be a universe which was already expanded beyond where we are at the beginning of our ability to see galaxies. So we came of with a new theory. The main reason for this theory seems to be so we could keep the Big Bang theory. Now we theorize the expansion is increasing? So there was a very fast expansion, then everything slowed so we could see what we see, then expansion is increasing again. I don't think we need to throw away what we have done, but we need to refine our measurements and be open to a new theory if it fits all the hard points.
The bigbang happened everywhere in the universe, there is no center, there was no explosion... hypothetically speaking.
Yep, as the comment above said: the big bang didn’t occur at a single place. It occurred “everywhere”. We know space is expanding, but it’s not expanding in one direction from a source to a destination (I suspect many people mistakenly view the known Universe as a sphere, with the big bang in the centre - this is actually mistaken). It’s more accurate to imagine the space between all objects expanding in all directions simultaneously.
Also, technically speaking, we only know that the early Universe was very hot and dense. At a certain point, known physics break down. The label we use to describe the point beyond is “big bang”. However, technically, we don’t know what the Universe’s initial conditions were. It may be, for example, that there was never a “beginning” in the way we intuitively understand it. It could be (as Penrose suggests), that the Universe periodically expands and then contracts and expands again - perhaps forever and ever. Also, some theories suggest that space and time themselves are emergent properties and are not fundamental to reality.
As humans, we experience the arrow of time. It is plausible that we are trapped by our experience of time and are unable to access its true nature. As a result, even positing a “beginning” of the Universe could be highly erroneous - it may be “the wrong question”, as some say.
Hi Brian, what about the cosmological constant ? Is anything confirmed other than the standard model the higs boson ? For the rest nothing has happened for the moment. The Guth inflation theory is put in question ! SWT has shown confiquring galaxies much more earlier than the inflationary model , much more older than supposed., nothtig to do with te mass of the electron..
Not the system of the inflationary model, is in question, only iI supposes a little bit older. But we have the Linda’s theorem ? Multiverse/fine tuning/strings ?
For me the plausible outcomes are curled up strings (how dimensions I don’t know) its for the moment the most obvious.
Other than de Sitter Space as the Plank length, holographical prinipal. Collision of branes JWST has demonstrated a very big void 1.8 bilions LY across. Which can concure with string tjheory, as branes
as a layman i feel that dark energy and dark matter may have all the solutions to all the queries of expanding universe dark hole gravity formation of universe
