A good conversation is always worth going back to. Thnx doc. It would be fitting to redo this conversation, but this time discussing Roy Kerr’s, recent work on rotating BH’s relating as such to our own Milky Way BH. If possible let the man from Christchurch (whats in a name) join. Eric Weinstein can add the mathematics of a puncturing torus, having the unique mathematical topology to reshape into its orthogonal alter ego. (See wikipedia animation) . This is how BH’s form. The inversion of particle and grid properties that come with it should again be of interest of Penrose, who always stresses mass is equal to inverse time (i.e. the clock in the QP world,) just as anergy and space will flip in their grid and potential role. that will satisfy Kerr answering what the inner ring is made of. Seems like cosmolgy needs a kick start after 60 years. Kerr blew the whistle.hora est gentlemen.
Why is Eric constantly brought in on these shows? He is not a serious researcher, he won't respond to peer review, drags his feet putting his ideas to paper, and is mostly just running a hedge fund and doing the podcast circuit? Wouldn't it be better to actually go out and get people, Phds, working on theories rigorously and not as an on-again-off-again hobby they can't be bothered to be serious about? Geometric Unity got some serious holes busted in it by peer review and he has never responded to fix them. Compare that with say, Andrew Wiles, who spend his life proving Fermat's Last Theorem, and on his first publish, peer reviewers found lots of issues. He went back in, fixed all of the issues, and then got the Fields Medal. If Eric is serious about Geometric Unity, he has to respond to peer review.

Penrose is a generational talent.

My father was fond of saying, "well, wasn't that a singular something!" So I propose that we replace the term 'singularity' with 'singular something'. That should clear everything up.

Everything is made of gravity. Strong and weak forces ride gravational waves and Fourier gives us the means to define spins. Everything is made from waves and spins.
Any concept of the singularity has to be at minimum spherical by nature, as a result of chaotic motion, because any order imparted as such will always produce a geometrical construct as a result.
What about 1 dimensional? And I think shape variables breakdown when going into higher dimensions. Im just reading through the comments but will go watch the video.
At this point in physics , from my outsider perspective, it seems like being a physicist is a bit of a disadvantage. Issues of publishing, reputation, and conservative constraints are nowadays too constraining to achieve the next big break... which means physics is due for a paradigm shift. I have a few ideas of where that shift might be headed, but even if I'm wrong about the details, the amount of effort it takes to gain even relatively small territorial gains is disproportionate compared to other eras of physics, due to the unwillingness to take necessary risks. There is always new ground, but at some points, a punctuated equilibrium of sorts -- a paradigm shift -- must precede discovery of new, fallow ground.
He's probably doesn't care and just enjoys talking. Eric is a non entity interested in self promotion. He was denied a nobel prize along with his brother(in different fields LOL)
These are undeniable two of the smartest persons around when geometry and spacetime is concerned. We may add Roy Kerr into the mix as well. Kerr’s recent seminal work on the ring shaped singularity inside a rotating black hole deserves far more attention, because all BH all rotating, none are static. I’d like Roger and Brian’s take on Kerrs work on these ringularities and discuss what happens to the cosmoc sag a* ringularity if turning into a 2D naked version thereof. It has consequences for grasping the structure of our own galactic plane and thus the distortions of any light reaching us from beyond our galactic plane. What could be more consequential than that??. Any chance to have a team up / discussion between these 2 epic black hole oldtimers on your show Brian? It would be an event for the ages, no matter what …
Have you noticed that particle physics is one of those subjects that you can speak intelligently about and yet not know that much really about the subject . Everyone seems to have a theory of the quantum world of gravity .
Penrose is a gem of a great scientist. Some of the latest ideas he is advocating, such as consciousness and cyclic cosmology, are very creative and somewhat speculative, and therefore he is taking great risks to push the envelope. This is what great scientists do.
I'm just an ordinary person that loves all things science. I know just enough about astrophysics and quantum mechanics to get me into a bit of trouble, I'm sure. But, what if we're missing some piece or pieces of Mathematics, quantum mechanics, or some deeper understanding of GTR. Have theoretical scientists gone down the wrong path. Does matter even fall into a black holes ( yes, I'm aware of the Nobel prize). Are black holes a pure spacetime construction. Did the inflationary hot big bang model happen as we all think it did. I have silly theories of my own. I have even created a 9 space dimensions universe with 1 or 2 time dimensions (might travel in opposite directions like a primary and secondary) theory that I'm sure nobody wants to hear. Well, I better quit typing and go to bed before somebody thinks I'm some kind of koook. Anyway absolutely love the video. Gonna be sure to watch the full version tomorrow. ❤
If we leave the planet and visit the planets and stars it will be because of these two mathematicians If we ever have an ‘intelligent’ conversation with a none human intelligence, it’s these two men I want asking the questions and taking the notes. Never thought I’d see these two together thinking aloud. If chess is the gymnasium of the mind. These two are for my mind - like a full on marathon ran backwards. Humbling and inspiring In equal measure. Thanks Dr Brian.
Are they really "versus"? As I understood, they agree, that GR is not a fundamental theory because it breaks down on the description of singularities and tat that therefore, singularities are not rea, but mathematical artefacts. Thanks for the post.
Gravity is a tricky thing it's not supposed to have SI units even, consider the alphabetical table let S (entropy) be 19 and 11 be the Boltzmann constant then 19 mod 11=8 @ entropy 1atm , boltzmann constant 1.380649×10^-23 multiplied by the avogardo number is 6.02×10^23= 8.3 beware numbers were switched up playfully or the universe is not straightforward?It might be that even our physics constant are not even close enough but the standard equation should be (entropy/Boltzmann constant)*Avogardo number to get an absolute number as a solution which should relate to 8 or symbol h. In the Einstein model E=5 m=13 c=3 hence its the best because it also follows Fibbonacian sequence 1,2,3,5,8,13,21,34,55 etc there is always a different perspective to looking at things.
Quantum gravity already exists. It is called space particle dualism or SPD-quantum gravity. It is needed because newton and Einstein were wrong in assuming that gravity is proportional to mass/energy. It is proportional to baryon count. And of course singularities are just as nonsensical as event horizons. Quantum mechanics demands an absolute frame of reference and Penrose knows that very well.
My respect to all of you ❤😊 Of course, singularity is unreal. It is a flaw of the theory. We should find a new mathematical formalism to construct a full-fledged theory of quantum gravity.
The earth is flat locally the same as the speed of light is the same locally but not on a larger scale. The earth is round and the speed of light depends on the measures of time and distance which change depending on the amount of gravity in the surrounding area. This means that distant starlight arrives instantaneously from distant galaxies which aren’t as far away as they appear to us to be with our measures of time and distance and the time is also passing by at a much faster rate since there’s no matter between us and distant galaxies to slow down time or shorten distance according to general relativity which is now an observation and not just a theory. …and things approaching a black hole look stopped to us because of how slow they are moving.
Singularity in equations always point out where the theory breaks down for example the Ultraviolet Catastrophe which led to the discovery of Quantum Mechanics.
J. R. R. Tolkien, who is widely regarded as one of the greatest writers of the fantasy genre, invested an extraordinary amount of his life into crafting the lore of Middle-earth. He created a rich world that feels very real to the dedicated fans of his work, who spend hours arguing over the smallest details of Middle-earth's fictional history. If Tolkien had believed he was somehow psychically channeling the history of a real world that actually existed in the past, and his fans were drawn into that delusion by Tolkien's masterful command of the English language, they would all be regarded as lunatics 😂
Whether or not to include the "or not" every time one says "whether". Or not. (Pro Tip... don't do it. The idea that there's a negative alternative is implied by the use of "whether")
If a man was able to see a black hole singularity, it would be like when King Arthur called upon Excalibur’s power to change an unalterable law and defeat Lancelot. The unbreakable sword of power, broke. Any man would be utterly destroyed for his inability to physiologically handle what is being force fed into his consciousness. It’s like seeing God.
@@dredrotten he certainly knows all lot about physics and talks about it. I have heard him speak volumes on physics so he is considered a physics bro in my mind.
For various reasons I think there's a kind symbiotic ebb and flow between gravity begetting QM which begets gravity and so on, due to more fundamental information dynamics that post inflationary transitions set up. That is I think it is a bit of an illusion that gravity and QM are strictly simultaneous or fundamental aspects of reality that will answer the bigger questions in of themselves combined.
Can someone write a book or do a podcast to explain: what is a layperson to do if the physics community overlooks something obvious... Spacetime is expanding. That means that spacetime is exerting a positive pressure. That means that if anything gets in the way of that, it obstructs the positive pressure. An obstruction to positive pressure is a negative pressure. Matter is an obstruction to the positive pressure of expansion of spacetime. Gravity is not a separate force. Gravity is just the effect of an obstruction of the positive pressure of expansion of spacetime.
And when talk about the big bang, who is to say there weren't MULTIPLE big bangs. What happens at the singularity of a black hole? well if you keep crushing, turns into a quark and then... well, turns into space time itself. So while blackhole recycle matter, they also generate the very fabric of spacetime for existance to exist on?
We have 60 to 70 years where no one has published any decay rates of dates that contradict. If your lucky they noted but didn't mention it in what published. This is a lot of list data .evolutionary human family tree just suddenly changed recently radically different than we've been feed for generations. For the sack of all that is good in science we need to fix things like this in those disciplines
Penrose: the water is boiling. What happened before the water started boiling or, how it started, is irrelevant. The water is boiling now and thats all that matters.......... All he's said is he doesn't know bugger all in a lenthy manner.
@DrBrianKeating, And of course the elephant in the room Edward Witten is not mentioned. Lots of respect to Sir Roger and his noble prize but Witten has done more for theoretical physics in the last 50 years than Sir Roger would be able to achieve in 100 life times. Nobody will debate Edward Witten on Quantum Gravity or super string theory because everyone who has ever debated him get fried, Edward is 1,000,000 times smarter than everyone else on the planet (quote from Brian Green) and a quote from Weinstein. "I am dumb enough not to be afraid to debate anything with anyone on the planet, with the exception of Edward Witten, who I am terrified of!".
Theory, theory, theory...Let's get a machine, an experiment that we can actually use to explore a [ new] technology. Otherwise, it just become a mental exercise. Don't know what it would take to make that happen or even where scientists would begin.
Regarding the “back-in-time” previous post and Penrose CCC( not Russian I think) at the beginning in our direction vs the mirror of our direction vs Penrose Ccc// if “the Penrose “ is on the other side of the BB then there is no correlation to symmetry in the mirror( because it’s not a mirror it’s a Mobius (?) Klein bottle (?) However in the Mandelbrot version it’s helicoid: toroid catenoid: polar grid disc… minimal surfaces of STE( space-time-energy) However in just a gigolo … I mean I ain’t got nothing nobody cares for me… no body… I’m so sad and lonely… Dang I hate it when ..
When are physicists going to talk about how empty spacetime exerts positive pressure, how we know this (Casimir effect and gravity), and what it means for quantum gravity.
Maybe the “beginning” of the universe was a massive particle decay and we are in one of its stages of decay. Perhaps the expansion will continue until the next decay and maybe the space between relates to its and particle decay
The mechanism of gravity is in-plain-sight. Open your eyes, and your mind, and you will indeed elicit the mechanism. It is indeed quantum in origin, but it is not what you may think. A, not a theory, but a Model of Everything will be published in 2024. It answers most, if not all, open problems in physics - with all the numbers to prove it; so it is not just a rhetorical argument. Also, singularities do not exist. They are a purely mystical notion with no basis in reality. Think about it; infinite gravity in infinitesimal space must predict the instantaneous contraction of the entire Universe. How is that compatible with a reality within which a Universe does indeed exist and therefore, not subject to the dire effects the singularity predicts?
Whats a good route to eventually be able to have impeccable math in reference to whatever topic is it just learn everything follow a path or ask a question learn the math that surrounds it and focus on that until you can work with it?
Suggestion. Find something that holds your interest. Learn what you need as you go along. In detail, when you encounter a term you don't understand or a concept. Write it down and find out about it. Then just carry on. (What holds your interest may change as you go along)
what do you think about Roy Kerr's newest article, stating that things with rest mass do not necessary end up in the singularity in fact singularities do not exist? arXiv:2312.00841 "There is no proof that black holes contain singularities when they are generated by real physical bodies. Roger Penrose claimed sixty years ago that trapped surfaces inevitably lead to light rays of finite affine length (FALL's). Penrose and Stephen Hawking then asserted that these must end in actual singularities. When they could not prove this they decreed it to be self evident. It is shown that there are counterexamples through every point in the Kerr metric. These are asymptotic to at least one event horizon and do not end in singularities. "
The universe is right? Or left, chiral pun intended? Electrons, protons, neutrons and photons know what they are, both waves and particles and behave accordingly, both bipolar, real and virtual? The universe by definition is singular, and contains all the consciousness and calculations or physical laws it requires to exist, even if it is a holographic projection as some infer? A main question is- is it boundless or confined within a self-compensating error-correcting spheroid, or slightly asymetric ellipsoid with closed spacetime curvature? Gravity or universal acceleration or free fall requires something to relate to or confine it or observe it the latter at light speed, and to take note as a kind of memory to exist? Confinement could be achieved with things like event horizons, cell membranes or magnetic flux tubes? If event horizons, gluons and cell membranes did not exist would anything? Or, is the universe a self replicating dream or computation as Spinoza and Wolfram posit? As an analogy, could a white blood cell that has some agency and purpose and ephemeral existence, figure out and understand the relatively universe sized mammal and all of its comrades' sample population contained therein mammal, perhaps trillions of them in a blue whale? Feel free to question comment or criticize! Vibrating the laryngeal chords and projecting sonic waves via vocalizing is therapeutic! The wind is the best medium for transmitting coded sounds with ideas attached to them!
You're not discussing the ontological structure of what causes gravity/wavefunctions (QM)/physics constants to exist. I don't know what kind of future humanity has if the physics community can't come up with some new experiments that can probe a greater understanding of how nature works.
Eric, I could not be more grateful for your charming analogy of Sir Roger Penrose to jazz artist, Sun Ra whom I’d not heard of. I immediately looked him up & it connected some large dots for me - thank you!
❤ with love for new experiences. BIG ERROR in measuring the Universe. Let's do the Michelson-Morley experiment on a school bus and determine the speed in a straight line - this is exactly the experiment Einstein dreamed of. Perhaps we will see the postulates: “Light is an ordered vibration of gravitational quanta, and Dominant gravitational fields control the speed of light in a vacuum.” There is a proposal for the joint invention of a HYBRID gyroscope from non-circular, two coils with optical fiber, where the light in each arm travels 18,000 meters, without exceeding the parameters of 0.4/0.4/0.4 meters and mass - 4 kg. ???
In the not too distant future I can imagine a university lecturer placing many of todays theorists alongside those of Plinny the Elder just to emphasize that making assumptions from so little information and passing it off as fact makes an 'ass out of you and me' = assume
If anti-de Sitter space curves outward from the soup can why do inflation diagrams for CCC stop without completing the donut? The a-dS torus shape reverses due to Newtonian gravity reassertion as inflation momentum wanes. A donut frosted by galaxies can communicate via ER=EPR phenomena with two loci for BHs to connect via wormholes and/or collect dark matter for Oppenheimer recombustion.
If I have a Planck spacetime sphere 28 meters wide, given to me by the Creator of the universe, and I can order it to do anything (physics related), then you have a problem. What happens if I order that 28 meter sphere to absorb EVERY gravity wave that crosses its boundary?

Given that Weinstein is a deliberately obtuse sith lord and Penrose is a independently thinking genius. I'll side with Roger
Not sure why Penrose chooses to debate with an individual with near zero contributions to the fields of QM and GR.
He's probably doesn't care and just enjoys talking. Eric is a non entity interested in self promotion. He was denied a nobel prize along with his brother(in different fields LOL)

Gravity, the opposite of light, is from positrons inside of protons and neutrons.
These are undeniable two of the smartest persons around when geometry and spacetime is concerned. We may add Roy Kerr into the mix as well. Kerr’s recent seminal work on the ring shaped singularity inside a rotating black hole deserves far more attention, because all BH all rotating, none are static. I’d like Roger and Brian’s take on Kerrs work on these ringularities and discuss what happens to the cosmoc sag a* ringularity if turning into a 2D naked version thereof. It has consequences for grasping the structure of our own galactic plane and thus the distortions of any light reaching us from beyond our galactic plane. What could be more consequential than that??. Any chance to have a team up / discussion between these 2 epic black hole oldtimers on your show Brian? It would be an event for the ages, no matter what …
Have you noticed that particle physics is one of those subjects that you can speak intelligently about and yet not know that much really about the subject . Everyone seems to have a theory of the quantum world of gravity .
Penrose is a gem of a great scientist. Some of the latest ideas he is advocating, such as consciousness and cyclic cosmology, are very creative and somewhat speculative, and therefore he is taking great risks to push the envelope. This is what great scientists do.
I'm just an ordinary person that loves all things science. I know just enough about astrophysics and quantum mechanics to get me into a bit of trouble, I'm sure. But, what if we're missing some piece or pieces of Mathematics, quantum mechanics, or some deeper understanding of GTR. Have theoretical scientists gone down the wrong path. Does matter even fall into a black holes ( yes, I'm aware of the Nobel prize). Are black holes a pure spacetime construction. Did the inflationary hot big bang model happen as we all think it did. I have silly theories of my own. I have even created a 9 space dimensions universe with 1 or 2 time dimensions (might travel in opposite directions like a primary and secondary) theory that I'm sure nobody wants to hear. Well, I better quit typing and go to bed before somebody thinks I'm some kind of koook. Anyway absolutely love the video. Gonna be sure to watch the full version tomorrow. ❤
If we leave the planet and visit the planets and stars it will be because of these two mathematicians
If we ever have an ‘intelligent’ conversation with a none human intelligence, it’s these two men I want asking the questions and taking the notes.
Never thought I’d see these two together thinking aloud.
If chess is the gymnasium of the mind. These two are for my mind - like a full on marathon ran backwards. Humbling and inspiring In equal measure.
Thanks Dr Brian.
Two of the greatest Scientific minds today.
Are they really "versus"? As I understood, they agree, that GR is not a fundamental theory because it breaks down on the description of singularities and tat that therefore, singularities are not rea, but mathematical artefacts. Thanks for the post.

Mr. Keating, none of them are completely wrong. There are layers!!!
Gravity is a tricky thing it's not supposed to have SI units even, consider the alphabetical table let S (entropy) be 19 and 11 be the Boltzmann constant then 19 mod 11=8 @ entropy 1atm , boltzmann constant 1.380649×10^-23 multiplied by the avogardo number is 6.02×10^23= 8.3 beware numbers were switched up playfully or the universe is not straightforward?It might be that even our physics constant are not even close enough but the standard equation should be (entropy/Boltzmann constant)*Avogardo number to get an absolute number as a solution which should relate to 8 or symbol h. In the Einstein model E=5 m=13 c=3 hence its the best because it also follows Fibbonacian sequence 1,2,3,5,8,13,21,34,55 etc there is always a different perspective to looking at things.
Quantum gravity already exists. It is called space particle dualism or SPD-quantum gravity. It is needed because newton and Einstein were wrong in assuming that gravity is proportional to mass/energy. It is proportional to baryon count.
And of course singularities are just as nonsensical as event horizons. Quantum mechanics demands an absolute frame of reference and Penrose knows that very well.
My respect to all of you ❤😊 Of course, singularity is unreal. It is a flaw of the theory. We should find a new mathematical formalism to construct a full-fledged theory of quantum gravity.
I think it makes more sense to look at singularities as limitations of the theory itself.
The earth is flat locally the same as the speed of light is the same locally but not on a larger scale. The earth is round and the speed of light depends on the measures of time and distance which change depending on the amount of gravity in the surrounding area. This means that distant starlight arrives instantaneously from distant galaxies which aren’t as far away as they appear to us to be with our measures of time and distance and the time is also passing by at a much faster rate since there’s no matter between us and distant galaxies to slow down time or shorten distance according to general relativity which is now an observation and not just a theory. …and things approaching a black hole look stopped to us because of how slow they are moving.
Roger is pure class to entertain, in good faith, Eric - as others would not.
Singularity in equations always point out where the theory breaks down for example the Ultraviolet Catastrophe which led to the discovery of Quantum Mechanics.
No singularities. Don’t need quantum gravity. Gravity is emergent from quantum
J. R. R. Tolkien, who is widely regarded as one of the greatest writers of the fantasy genre, invested an extraordinary amount of his life into crafting the lore of Middle-earth. He created a rich world that feels very real to the dedicated fans of his work, who spend hours arguing over the smallest details of Middle-earth's fictional history. If Tolkien had believed he was somehow psychically channeling the history of a real world that actually existed in the past, and his fans were drawn into that delusion by Tolkien's masterful command of the English language, they would all be regarded as lunatics 😂
Whether or not to include the "or not" every time one says "whether". Or not.
(Pro Tip... don't do it. The idea that there's a negative alternative is implied by the use of "whether")
If a man was able to see a black hole singularity, it would be like when King Arthur called upon Excalibur’s power to change an unalterable law and defeat Lancelot. The unbreakable sword of power, broke. Any man would be utterly destroyed for his inability to physiologically handle what is being force fed into his consciousness. It’s like seeing God.
can we plz have a part 2 of this discussion, like 4 hours long and do it every month plz plz
Old conversation, and the phone ringing throughout. Please stop both of these practices.
First, we need to establish if gravity is a force or a curvature of space before trying to unify it with another theory.
My three favorite physics bros!🍿
Weinstein isn't a Physicist
? He is a mathematician who tries to pass himself off as one.
@@dredrotten he certainly knows all lot about physics and talks about it. I have heard him speak volumes on physics so he is considered a physics bro in my mind.
For various reasons I think there's a kind symbiotic ebb and flow between gravity begetting QM which begets gravity and so on, due to more fundamental information dynamics that post inflationary transitions set up. That is I think it is a bit of an illusion that gravity and QM are strictly simultaneous or fundamental aspects of reality that will answer the bigger questions in of themselves combined.
Can someone write a book or do a podcast to explain: what is a layperson to do if the physics community overlooks something obvious...
Spacetime is expanding. That means that spacetime is exerting a positive pressure. That means that if anything gets in the way of that, it obstructs the positive pressure. An obstruction to positive pressure is a negative pressure. Matter is an obstruction to the positive pressure of expansion of spacetime. Gravity is not a separate force. Gravity is just the effect of an obstruction of the positive pressure of expansion of spacetime.
💯 agree with Penrose's analogies of Weyl and Ricci curvatures.

There is no "versus" here.
Good content doesn't use clickbait tactics.
And when talk about the big bang, who is to say there weren't MULTIPLE big bangs. What happens at the singularity of a black hole? well if you keep crushing, turns into a quark and then... well, turns into space time itself. So while blackhole recycle matter, they also generate the very fabric of spacetime for existance to exist on?
at 5:45 Every time I watch World Science Festival I find myself wondering whether those guys took too many drugs in college, or not enough.
Eric needs to let gray happen. No one is buying that your hair is shoe-polish black.
We have 60 to 70 years where no one has published any decay rates of dates that contradict. If your lucky they noted but didn't mention it in what published. This is a lot of list data .evolutionary human family tree just suddenly changed recently radically different than we've been feed for generations.
For the sack of all that is good in science we need to fix things like this in those disciplines
You’re getting some heavy hitters on here: Lee Smolin and now Roger Penrose!
the regulated consumption of matter implies that it is a whirlpool rather than a waterfull.
Penrose: the water is boiling.
What happened before the water started boiling or, how it started, is irrelevant.
The water is boiling now and thats all that matters..........
All he's said is he doesn't know bugger all in a lenthy manner.
This so awesome. What an honor and gift.... Inspired me to memorize the periodic table
Thank You
Did you discuss Kerr's paper on singularities in this podcast?
@DrBrianKeating, And of course the elephant in the room Edward Witten is not mentioned.
Lots of respect to Sir Roger and his noble prize but Witten has done more for theoretical physics in the last 50 years than Sir Roger would be able to achieve in 100 life times.
Nobody will debate Edward Witten on Quantum Gravity or super string theory because everyone who has ever debated him get fried, Edward is 1,000,000 times smarter than everyone else on the planet (quote from Brian Green) and a quote from Weinstein. "I am dumb enough not to be afraid to debate anything with anyone on the planet, with the exception of Edward Witten, who I am terrified of!".
Theory, theory, theory...Let's get a machine, an experiment that we can actually use to explore a [ new] technology. Otherwise, it just become a mental exercise. Don't know what it would take to make that happen or even where scientists would begin.
Regarding the “back-in-time” previous post and Penrose CCC( not Russian I think) at the beginning in our direction vs the mirror of our direction vs Penrose Ccc// if “the Penrose “ is on the other side of the BB then there is no correlation to symmetry in the mirror( because it’s not a mirror it’s a Mobius (?) Klein bottle (?)
However in the Mandelbrot version it’s helicoid: toroid catenoid: polar grid disc… minimal surfaces of STE( space-time-energy)

Dang I hate it when ..
Eric, a clue for you; Observer's lens shapes reality: gravitational singularity, or gravitational void? One coin, two faces.
When are physicists going to talk about how empty spacetime exerts positive pressure, how we know this (Casimir effect and gravity), and what it means for quantum gravity.
P E N R O S E
Maybe the “beginning” of the universe was a massive particle decay and we are in one of its stages of decay. Perhaps the expansion will continue until the next decay and maybe the space between relates to its and particle decay
Could singularities. Before the Big Bang, black holes etc simply be the place where our universe crosses over to the 5th dimension?
Quantum gravity builds everything in the Universe so yes you need Quantum Gravity... next!
Two of the greats! Excellent
The mechanism of gravity is in-plain-sight. Open your eyes, and your mind, and you will indeed elicit the mechanism. It is indeed quantum in origin, but it is not what you may think. A, not a theory, but a Model of Everything will be published in 2024. It answers most, if not all, open problems in physics - with all the numbers to prove it; so it is not just a rhetorical argument. Also, singularities do not exist. They are a purely mystical notion with no basis in reality. Think about it; infinite gravity in infinitesimal space must predict the instantaneous contraction of the entire Universe. How is that compatible with a reality within which a Universe does indeed exist and therefore, not subject to the dire effects the singularity predicts?
Whats a good route to eventually be able to have impeccable math in reference to whatever topic is it just learn everything follow a path or ask a question learn the math that surrounds it and focus on that until you can work with it?
Suggestion. Find something that holds your interest. Learn what you need as you go along. In detail, when you encounter a term you don't understand or a concept. Write it down and find out about it. Then just carry on. (What holds your interest may change as you go along)
what do you think about Roy Kerr's newest article, stating that things with rest mass do not necessary end up in the singularity in fact singularities do not exist? arXiv:2312.00841
"There is no proof that black holes contain singularities when they are generated by real physical bodies. Roger Penrose claimed sixty years ago that trapped surfaces inevitably lead to light rays of finite affine length (FALL's). Penrose and Stephen Hawking then asserted that these must end in actual singularities. When they could not prove this they decreed it to be self evident. It is shown that there are counterexamples through every point in the Kerr metric. These are asymptotic to at least one event horizon and do not end in singularities. "
Okay by the middle of the video I understand why you uploaded this video
He is so sharp for his age just as a comparison he is 10 years older than joe Biden.
You need quantum gravity to explain how virtual particles create vacuum energy.
The universe is right? Or left, chiral pun intended? Electrons, protons, neutrons and photons know what they are, both waves and particles and behave accordingly, both bipolar, real and virtual?
The universe by definition is singular, and contains all the consciousness and calculations or physical laws it requires to exist, even if it is a holographic projection as some infer? A main question is- is it boundless or confined within a self-compensating error-correcting spheroid, or slightly asymetric ellipsoid with closed spacetime curvature? Gravity or universal acceleration or free fall requires something to relate to or confine it or observe it the latter at light speed, and to take note as a kind of memory to exist? Confinement could be achieved with things like event horizons, cell membranes or magnetic flux tubes? If event horizons, gluons and cell membranes did not exist would anything? Or, is the universe a self replicating dream or computation as Spinoza and Wolfram posit?
As an analogy, could a white blood cell that has some agency and purpose and ephemeral existence, figure out and understand the relatively universe sized mammal and all of its comrades' sample population contained therein mammal, perhaps trillions of them in a blue whale?

You're not discussing the ontological structure of what causes gravity/wavefunctions (QM)/physics constants to exist. I don't know what kind of future humanity has if the physics community can't come up with some new experiments that can probe a greater understanding of how nature works.
Eric, I could not be more grateful for your charming analogy of Sir Roger Penrose to jazz artist, Sun Ra whom I’d not heard of.
I immediately looked him up & it connected some large dots for me - thank you!
Please interview Nima Arkani Hamed.
#Centripical-force ... With no movement, no gravity required. With movement we get gravity. A by-product of motion. 😊
❤ with love for new experiences. BIG ERROR in measuring the Universe. Let's do the Michelson-Morley experiment on a school bus and determine the speed in a straight line - this is exactly the experiment Einstein dreamed of. Perhaps we will see the postulates: “Light is an ordered vibration of gravitational quanta, and Dominant gravitational fields control the speed of light in a vacuum.” There is a proposal for the joint invention of a HYBRID gyroscope from non-circular, two coils with optical fiber, where the light in each arm travels 18,000 meters, without exceeding the parameters of 0.4/0.4/0.4 meters and mass - 4 kg. ???
I’m leaning towards Penrose
I want to hear Sir Roger’s take on Kerr’s paper
At what point in this video did they actually talk about quantum gravity?
Sorry, what real Physics has Weinstein done? It’s embarrassing he’s even on the same podcast as Penrose.

Eric, kudos for the Sun Ra mention.
Sun Ra, yes, HE should have become a physicist!

If anti-de Sitter space curves outward from the soup can why do inflation diagrams for CCC stop without completing the donut? The a-dS torus shape reverses due to Newtonian gravity reassertion as inflation momentum wanes. A donut frosted by galaxies can communicate via ER=EPR phenomena with two loci for BHs to connect via wormholes and/or collect dark matter for Oppenheimer recombustion.
