Penrose is a generational talent. As is apparent with the Nobel Prize (black hole formation) and Wolf Prize (with Hawking for Penrose-Hawking Singularity Theorems), the relative intellectual stature of these men is not close... and it's a bit of a vanity jerk for Weinstein to be taking first billing and pretending this vid is some sort of legitimate contest in the same intellectual weight class. Penrose is also a humble man who reaches to share his love for the craft of maths and physics, including indulging in this "debate" to take his love of physics and maths to new UKposts audiences.

I like how Roger is the combined age of the two of you and still articulates as if he were the same age as you two.

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.

For everyone's transparency, this video is 3 years old.

Comparing Penrose with Weinstein is like comparing an iPhone with a rock. :D

Re-posting years-old discussions without a date/timestamp is a deceptive practice for more clicks/views and makes me less likely to continue following your content moving forward. This is a repeated pattern of behavior, unfortunately.

Me watching this conversation is much like a golden retriever listening to Mozart.

In CCC, wouldn't the singularity be the conformal edge? I know Sir Penrose theorizes that ccc begins and ends with aeons but is it totally necessary for that all or nothing approach?

The only thing I can bring up right off the bat is that a singularity shows up in convex or concave mirror in your last video was very crucial for this and I know this seems very simplistic but it's a crucial importance and all powerful things are usually simplistic

Singularity state is like trying to reach absolute zero just in the opposite direction but heat and cold are basically the same thing at extreme enough temperatures. Good video giving clarification of though process... Penrose kinda touches on letting go of 3d thinking to find the answer but spin is just a description of a 3d state. Another great well though out clip to post.💯💚💜

Thanks Dr Keating!

What a fantastic conversation to be able to watch! 👍

can you provide link to full length discussion?

I didn't understand even a single sentence... but just WOW...🙃

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?

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.

Hey, is the full conversation somewhere on UKposts?

WHERES THE FULL CONVO KEATING!!!

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.

Singularity is the smallest form of reducible state of matter

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.

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.

Penrose. Btw he use almost the same framework I use as well. Twistors is the same family class as kahler geometry.

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.

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.

Once a sufficient energy density is reached, the conditions of a black hole are created. The expansion of spacetime created prevents a singularity, since nothing can move fast enough to reach the center or escape.

Dr. Keating, in times like this, I tell myself... It is better to be underpaid and overvalued than a Noble Prize Award Winner and undervalued.

Did you discuss Kerr's paper on singularities in this podcast?

Thank You

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. "

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")

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.

Roger Penrose is my hero. Weinstein is pretty cool too. These guys are looking under the rocks! Here is my idea: Time is a wave, yes? Explain the wake to me? I think it's gravity. That would explain a lot. Look at it: Time moves one way, and gravity pulls every so slightly back the other way. It keeps the geometric narrative of quantum math of existence on Earth attached to the sphere inside the multiverse as the math of existence unfolds.

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.

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 ..

So, dark matter? OK at the heart of galacty the blacksphere rules. What does it do exactly? Well, it forms the EMFS we reside in and it needs fuel to maintain fields strength. What is fuel? Fuel is the gaseous matter that's attracted to the boundary of the cores flipped EMFS. This means as it's normal form is presented it runs straight into this boundary system, as this is occurring it heats up and however slight the horizon is born. The horizon builds up and grows to enormous sizes all the while contributing to the overall system. But as this fuel is being used, the exhaust system must also get rid of the excess, how could this happen with such thermal Dynamics systems at work? Well it's not as daunting as we might think, once fuel is used it loses it charge as this is the fuel the charge. And as the charge is lost its incapable of remaining in the horizon so where does it go. The sphere (blacksphere) sucks it in and shoots it out in jets from both ends. So trying to detect this material becomes impossible because it's incapable of holding charge any longer. So as it is shot out of these jets it forms clouds ⛅️ and as the thermal Dynamics systems continue to work and heat is captured it allows us to use this waste for lenses. To peer deep into the infinite ♾️ vacuum space. That's my guess to what dark matter actually is, there's no place for it to go it's ejected into the vacuum space and forms clouds. These systems have been working for a very long time and all that waste has to be somewhere. If it's not dark matter? Where is it? Peace 😎 ✌️ from Canada, eh.

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

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?

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.

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.

I will say this, it is there. The real issue is our capabilities and the fact their not up to snuff at this time. But once we are hunting the spheres then our tech will upgrade automatically in this endeavor. The positive impact on science will be extraordinary, and I believe it will unlock some of those secrets that have eluded us thus far. I also believe that whilst on the hunt, we will stumble upon some other great ideas based on the different thinking that will be required. EMFSYSTEMS will be very important moving forward into the infinite ♾️ vacuum space. Peace 😎 ✌️ from Canada, eh. Love the video.

Singularity - just before a BigBang is, in my humble opinion, just another rabbit hole ... Eric is right that nitty gritty tensor analysis is UNDER TAUGHT in colleges... Edward Teller was dialed into this, and he personally told me that 'The BigBang Theory" grew out of 'Creative psychedelic wild mushroom theory'! ...Mary Fowler's Geophysics PREM chart offers a plausible alternative about where physics took a wrong turn decades ago - but its tensor analysis suggests perpetual motion!...WOW! ... I think the BigBang concept should be shelved next to Flat-Earth Theory (after all, a Flat Earth was a very reasonable concept 600 years ago.) ... Roger has nice 'no sharp elbows' in his manner of debating ...Always enjoyable to hear what he has to say about a topic...

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.

Brother you mis notated who is who. 7:02

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

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.

I think it makes more sense to look at singularities as limitations of the theory itself.

Could singularities. Before the Big Bang, black holes etc simply be the place where our universe crosses over to the 5th dimension?

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

❤ 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. ???

At what point in this video did they actually talk about 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.

First, we need to establish if gravity is a force or a curvature of space before trying to unify it with another theory.

gravity:positron::light:electron Gravity, the opposite of light, is from positrons inside of protons and neutrons.

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?

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.

can we plz have a part 2 of this discussion, like 4 hours long and do it every month plz plz

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. ❤

Turn the black hole inside out.... The "singularity" becomes and the "volume" between it and the "black hole" boundary open up into "a" or "the" universe. It's a 3d Penrose tile set akin to the angel and demons Escher painting, but in reverse (and 3d)....... Or not 🤔

You’re getting some heavy hitters on here: Lee Smolin and now Roger Penrose!

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!

This so awesome. What an honor and gift.... Inspired me to memorize the periodic table

You have to figure out what the building blocks are of spacetime quantum mechanics/physics constants. I'll give you a hint. You've seen them before in physics experiments.

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.

You need quantum gravity to explain how virtual particles create vacuum energy.

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 .

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

They say that Madonna is "singular"....and also GaGa...they are both "singh-ghee". Furthermore, would you say it is more of a tire than a donut?

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 😂

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.

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 …

Doesn't an infinite Conformal Cyclical Cosmology * as the alternative to a Hubblean expanding universe with a beginning and finite diameter, mean the universe is inherent, with permanency connoting static by contrast with dynamic and wouldn't a singularity as something which is it's opposite, also rule it out as a logical possibility in a consistent - sensical - theory where there aren't any contradictions : down can be an opposite to up as long as they aren't occupying the same space, like the water in a wave having various directions ** . * Recognizing infinity like in the definition of limit and zero results in a contradiction, from them behaving when multiplied by a finite number like substitutes, but complements under addition. ** Einstein apparently believed that any space has a dual space, maybe like ( { < } , □ ) for ( { > } , □ ) , where " { } " denotes set, " < " is an opposite set element to " > " evidenced geometrically by reflection about a vertical straight line segment - or by rotation about half a polygon - and " □ " is an algebra of rules governing the behavior of elements in the space.

Mr. Keating, none of them are completely wrong. There are layers!!!

Just hanging out picking my teeth lol

Eric, a clue for you; Observer's lens shapes reality: gravitational singularity, or gravitational void? One coin, two faces.

What if singularities only exist at certain points over the theoretical evolution of the universe? Therefore, we can't always see and or prove their existence.....

#Centripical-force ... With no movement, no gravity required. With movement we get gravity. A by-product of motion. 😊

You should watch the new kinetic magnet stuff and you may understand gravity

My three favorite physics bros!🍿

Why are physicists unwilling/unable to ask: what is spacetime made of?

Two of the greats! Excellent

There is no "versus" here. Good content doesn't use clickbait tactics.

Given that Weinstein is a deliberately obtuse sith lord and Penrose is a independently thinking genius. I'll side with Roger

I want to hear Sir Roger’s take on Kerr’s paper

Sir Roger Penrose looks a little like my father.

Set up all the technical before the conversation starts...

Problem of Metaphysical world

Can’t we use the photon ring to get a picture of inside a black hole?

Eric is a mathematician. Penrose is a Physicist.

Okay by the middle of the video I understand why you uploaded this video

Weinstein, I envy your gray matter, brother. 🤩

Singularity is just maths talk for work in progress.

Quantum gravity builds everything in the Universe so yes you need Quantum Gravity... next!

got exciting but then realized I listened to this one a few times already.

Hey - what about CIG Theory?

If: 1 putative quantum gravity suggested light time lag per energy and distance = sqrt((sqrt(2)G)/(ℏ c^7)) then: Physics is the geomancers invention or discovery to add & multiply c. 🌊 0.8409 P_P = ((Planck length)^-1 /sqrt((sqrt(2)G)/(ℏ c^7)))

roger is the definition of what i want to be like at 92
