Based on Professor Penrose’s conformal cyclic cosmology theory, I would like to suggest a couple of modifications. Specifically, mass turns into radiation through fusion, fission and hawking radiation. As total mass in the universe reduces, space-time expands. After the last proton decays into radiation, only electromagnetic waves are left, and the universe becomes a system of pure energy. At this point, the universe reaches maximum entropy, and with no mass, there is no more space-time. Wavelengths of electromagnetic waves become meaningless as well. Interestingly, at this point, with no space-time, what was supposed to be the state with maximum entropy and volume suddenly also becomes the state of having no volume and the lowest entropy (this is hard to understand per Professor Penrose). This condition is similar to the state described in the 10^-43 second “Planck Epoch”.
At Planck Epoch, the system has a pile of energy and has the minimum entropy. As prescribed by the second law of thermodynamics and the uncertainty principle, the stochastic nature and the need to get out of the state of minimum entropy suggest that some of the energy would suddenly convert into mass on a stochastic basis (remember e=mc^2), and with the emergence of mass, space-time would suddenly re-emerge. The key here is that the expansion process isn’t continuous, as suggested by the inflation process in the Big Bang Nucleosynthesis theory. Instead, it suddenly happens in a blink, and mass is distributed like the distribution of water droplets on a mirror after a splash, some big, some small, unevenly across the newly re-emerged space-time, with some energy not turning into mass and becoming background radiation we observe today. As mass turns into radiation through the fusion and fission processes, the total mass in the universe reduces, space-time expands, and the cycle repeats itself. This hypothesis presents a plausible alternative to the Big Bang Nucleosynthesis theory. The recent discovery of large galaxy systems at 400/500 million years post Big Bang supports this hypothesis. I hope this provides some food for thought and provokes further thinking. Cheers!
Brilliant info thanks a lot! Just curious, could you please expand on this - "The recent discovery of large galaxy systems at 400/500 million years post Big Bang supports this hypothesis". I recently heard about these anomalous galaxy sightings, how do they validate the CCC theory?
Damn. You only get half the Penrose experience without an overhead projector. One of the greatest living minds
Agreed. When I didn't see an overhead projector, I was a little disappointed
ridiculous
It's made even worse that the camera doesn't even occasionally focus on the slide.
He might have a great mind, but he had a very narrow perspective in thinking there was nothing before the big bang...what a waste of time without infinity in the equation?
Much more likely...William Blake was right. Often these incredible mathematicians seem to be horrible at theory. It is like they can't see the forest for the trees
I would put things this way from a prophetic quote of Gibran......there is the infinitely small and the infinitely large...
So....particles are containment....with containment there must be breach of containment...what goes in or down must come out or go up?
The small creates the large making fields of containment...the large creates the small when the containment fields cannot hold the energy within...hence infinity.
Energy cannot be created nor destroyed...it can only be contained and released. Is it a living infinity of conscious change...that is logical and defies logic at the same time? We call this God creation?
Infinity appears to be illogical...how can reality exist ?...but non infinity is also not logical...how can something come from nothing?
Maybe ii is 'Nothing' that has never existed and never will??
Why did God create time?
So everything does not happen all at once? 😁😁😁

When you have a 74 and 77 year old battling it out and they both lack fundamental knowledge in a lot of things. And they are both running for president.
Then you have Roger Penrose, 89 years old and is one of the most fluent physics speakers, and on of the smartest and ambitious physicist and mathematician in the entire world.
Then there's you with too much time comparing a physicist to a politician. Good and evil exist in human culture, which is too heavy to change too quickly.
Luckily America isn't the only place with political leaders.
The world is not a classroom of lab, our political leaders need real world experience. That’s why Einstein refused any political position he was offered, including the president of Israel.
Yet the 89 year old man is wasting his intellect speculating about completely useless things that do not affect us in the slightest. (I suppose that is better than the 77 year old man destroying our economy on purpose)
Believe it or not he has denounced white nationalism and is now liberal.

Penrose seems so genuine and humble.
He is - a lovely gentle guy
Sir Roger may have just discovered a way to prove the previous universe. If his hypothesis is correct, this is simply HUGE! I'm so thankful, he truly deserves his Knighthood and Nobel Prize. Outstanding man.
On that he is right but not how he draws it due that all systems are one circle into a bigger one.
Spot on. Roger Penrose is a great scientist and a humble man. His "incredibly complex geometry" 1:10^10^124, before the Big Bang, is a big step in our understanding of the Universe. As he says this is a "demonstrable fact".
Plainly you simply canot understand that any thing that attracts the epithet the universe-everything everywhere Evrywhen must be definition be unique; it is axiomatic that the re can only be *One* everything everywhere everywhen or totality.
If whatever you have in mind is not everything everywhere eveywhen and unique, hen it cannot possibly be the universe everything or totality. It is axiomatic that universals are unique; even a small imbecile child will tell you that there can *only be one* Everything, the universe or totality because by definition it is* All_Embracing* and if whatever you have in mind is not everything everywhere eveywhen and unique, then what you have in mind not only is not the universe, it is axiomatic that it*could not possibly* be the universe. In babytalk: there can only be One* Everything. If you struggle with that axiom try the shallow end of this particular pool. Similiter if you cannot grasp the idea of mutual exclusivity.
He gets a Nobel Prize on a 1965 mathematical work on black holes as being complimentary to Einstein's Theory of Relativity.
What he attempts to describe in this video, is not scientific or mathematical work and has several misunderstandings of astronomical proportions.
Penrose was a mathematical physicist, professor and theorist, not an astronomer or astrophysicist nor an experimental physicist.
He seems to cram the observed world into drawings by MC Escher.
His hypothesis doesn't have any scientific evidence and is largely philosophical.
@@SpaceCadet4Jesus says youtube rando with tiktok logic?
I was a biochem student at Oxford living with my maths friend in our rooms in the 90's. We were both interested in theories of the universe and I knew about Penrose. He was giving a lecture at the maths department way out of both of our leagues. But we decided to go. I sat in the front row. Roger had to write some text on the chalkboard - saying something like "Riemann sphere". It was illegible. He was struggling to write the simplest words. Then he needed to draw the 4 dimensional projection of an 8 dimensional complex space on a 2D blackboard - it was a work of art. The entire experience blew my mind and I have forever fascinated and studying all his work. I wish I could just drop him an email to say how he changed my life. Amazing, amazing man. He is a hero to me.
what I appreciate about this hypothesis is that it makes predictions about what we should see - just as Einstein's equations do. It's rare though at this level of cosmology which often times borders on philosophy rather than science.
The ideas make predictions which thus far haven't been observed nor found in the minutest details of volumous data.
He conflagrates different ideas together like an MC Escher drawing, hoping someday they turn out to be reality.
There is no science here when the postulates are incorrect and certainly he's performed no scientific tests to undergird his ideas.
I agree he was a great thinker in the 60's and 70's regarding mathematical ideas relating to Einstein's theories and black hole formations, which Nobel Prize he recently shared between 2 other people. A 1965 recognition long overdue, if you ask me.
Why have I only just discovered this man!?
His stuff on consciousness is fascinating.
Glad they found the biggest 32” tv they could find to help these seniors see his presentation clearly.
lol ikr! The mind boggles
If you increase the volume the temp. And pressure goes down if you decrease the volume or " squish the volume" the temperature and pressure goes up.
That reminds me of the Ideal Gas Law. V1 P1/T1 = V2 P2/T2 . That is an elegant equation.
What a mind! Penrose becomes more animated / interesting / sometimes hilarious in lectures rather than sit-down discussions. "but don't worry about that right now..." lol
It is a pity that full screen slides could not have been edited into the presentation.
They are the same slides he always uses in his lectures, check out any one of them
Poor Roger was asked to bring the computer monitor on his desk as part of his presentation.
21:08 when he's talking about black holes and their eventual demise (going pop / exploding), I thought a google years sounded like a scary amount of time. But when he illustrated his point saying : the graph is not to scale and it would be towards the edge of the universe when they go boom, my head exploded too!
What an honor and privilege to listen to this great scientist. He's the only one who really fills me with awe at his intellect and imagination. Wonderful.
Fascinating and so interesting! 👍👍👏👏
Many, many Thanks for the video!
I really wish that more scientists were like Roger Penrose. Don't misunderstand me, science rocks, quackery doesn't (I made it short). But science could rock even faster and harder.
Agreed! Roger's 'visualizations' (as I therm them) have a great charm of their own - I'd claim they're artworks - but can you imagine what full-bore Hollywood computer Generated Imagery could do?!
Physicists: Antimatter.
Sane person: You mean matter? Or a specific and unique counter particle that can cause annihilation(another illiterate word from physicists)?
Never heard about his guy in my youth but man he's so worth listening to.
When you listen to Roger Penrose, fasten your seat belt. World's greatest mind at the moment.
What date and where is this talk?
Does the Black holes or formers stars on bygone Eon have a names? I suggest two names Penrose and Roger . But then again the black holes seen there are not from invidual stars but homongous black holes bigger? than anything now or are they shrunk to ..what size ?
Passionately love this. Anything or anyone that provokes tantalising thought and thinking is just so profoundly wonderful.
I completely agree with you.
At time 28:04 he shows 4 sets of 2 rings where one is inside the other one where he says there must to be a difference in temperature from the inside circle to the out circle. - For sure those circles are there since all systems are like that, you dont have to go that far just take a look to the 4 rocky planets inside the inner asteroid belt and this inside asteroide belt inside the outer asteroid belt after Neptune where my guess the inside should always be hotter than the out side due that is closer to the sun or the nucleous. - As a rule the inside in radius is half the out side, as well is in matter, and gravity like is you add the gravity from the inside rocky planets you get 26M/S2 while the out side is 52M/S2.
I miss the jumbled mess of transparencies
A 40 inch TV with a picture that only uses half the screen isn't any better lol
Penrose is a brilliant guy with a great way of communicating, clearly on a path to answer the ultimate question. The nature of the universe beginning (or however it came to be) and...whatever the heck is happening after that in this sheet of space-time. Presenting to what appears to be an audience that wandered in for a low budget planetarium at a town fair. Mommy where's the stars?? I want to see Neptune! It looks rather uncomfortable in there, especially Sly Stallone. Penrose has produced some "very technical" fascinating work on physics and consciousness worth investigating as well. Awesome.
All very well. I think these scientists really exercise their imaginations to create ideas to avoid the reality of a Creator.
@@williammarzano872 Almost. The Creator has by now been found to not have created a gazillion of things that have been found explainable by science only. In 100% of all solved cases sofar.

Expressed in wisdom and ability of logical reason, how wise would someone be with this background info and no proof what so ever of the existence of a Creator, that 'yes but apart from that, all the other stuff science has not quite explained yet, comes from the Creator!' -statement will actually stand strong 'next time'?

Very interesting seminar. It would be wonderful if Professor Penrose can have a follow up seminar on how this might explain those larger than expected very early galaxies, among other things, observed by the James Webb telescope, in 2023.
Sir Roger, I believe the missing bit you are looking for is a rotational symmetry instead of a linear symmetry. At the end of the universe when black holes have doled out their last quanta of hawking radiation and the photons settle into a configuration where they cease to interact, the difference between complete entropy and total lack of entropy are a matter of scale. This reminds me of a Klein bottle in that entropy has returned to its origin without circling or crossing paths.
I understood this much better with his chat with Lex Freidman, without visuals. I just recently found out about Sir Penrose due to Richard Dawkins. Thank you for this Roger! :) I agree that the inflation theory seams a bit hard to imagine.
A bit off topic but concerning the quantum physics of black holes (to include the beginning of the universe as we know it), why are black holes not considered as a collapsed neutron star that has unfolded a multi-dimensional area of space to a singularly-dimensional area of space? As the three+ dimensional collapses it unfolds to a two dimensional space (the black hole as a 2-dimensional sphere) to a singularly-dimensional are of space (the singularity as a 1-dimensional sphere). Why is this not talked about more and why aren’t we talking about the inverse of unfolding multi-dimensional space (folding an area of space)? Your thoughts?
Awesome talk! Never knew about this guy until youtube feed preferences. I'll be researching more of his studies.
I often thought the universe was a reflection of another when I was younger, thanks to multi-universe comic books. Do super massive black holes collapse into singularities? Can multi-universes operate as a uniform collective? Or would one universe have to die before another born?
Every black hole contains a singularity/ringularity, black holes don't collapse, a dying star collapses into a singularity causing the black hole.
Well, There are two Contexts of how we can believe on CCC(Conformal Cyclic Cosmology):-
(1) Open Universe
(2) Closed Universe
in the Open Universe theory, the Universe would have to Expand Constantly according, to the Hubble's Constant(H0), it will be a challenge, Because, it would need a force to counter-attack the Force of Dark Matter/Gravity, to stable the Universe, or else it would expand Continuously(>H0) or collapse very Quickly.
In a Closed universe it remains static or constant.
If all matter and black holes decay, we are left with photons. For photons, there is no time. So at that point, space-like and time-like intervals could potentially swap. The entire universe could potentially collapse into a Schwarzschild black hole. In my opinion, such a non rotating black hole can only be made of the entire universe due to its symmetry, that's why you may have only one in the universe. At the event horizon of a black hole, time-like and space-like intervals swap. This leads to a pure singularity unless you still have a residual asymmetry (maybe both space and time intervals have a bottom limit which is not null). This would potentially cause a big bang. But no circles in the CMB are to be observed...
The laws of physics as we observe them only apply to our universe, they do not apply to anything besides our universe. Therefore no hypothesis within our universe can be formed to hypothesisze where our universe comes from.
@@brian-kt1rc hell yeah brian
Godel knew whats up
Surely if you have only photons, there are neither spacelike nor timelike intervals, but only lightlike ones? You need some mass to regain the other two kinds of interval.
Where the universe comes from is not a valid question in the first place... I don't see the link to what I wrote. You think of a multiverse, I think of the Universe (the possibility of a multiverse is still there though). You can make a hypothesis but you can't prove it... The multiverse is just a hypothesis. I supposed the universe as a whole with just one big bang, no leftovers...
@@mcsquared4319 u were on to something bruh💯👌🏾
His work resembles the infinity symbol itself. Marvellous stuff.
one idea about "infinity" . It's not infinite if it has a starting point as in observing the physical universe through a telescope and seeing no apparent limit or end.
How can you compress endless or eternity.
Of all the strange theories of what might have been Physically at The Begining & The End, this is the one which makes the most sense to me and if Sir Rog is Right I'm thinking he might be as The Maths Worx...
From a purely aesthetic standpoint I prefer his hypothesis of a repeating universe. I admit I don't understand the details, but it is comforting to think that if we humans screw up this iteration, there will be more opportunities to get it right in the future. The sad thing is it we may have figured it out in a past iteration but don't remember what it was. This is all reminiscent of Hoyle's great contraction which I guess got disproved by that stinker Hubble. We all have our disappointments in life
An honor to listen to this man. It's sad he has to use that miniature screen to share such a profound vision.
Marvelous.
And from the (statistically relevant) discovery of those rings, as pointed out by Penrose at the end of this discussion, I get the sense that his idea may have just nailed the whole concept of the Universe. His insight is worthy of Einstein, so now to solidify the proving of it.
We exist, are emergent, out of an MC Escher print. Who knew? Heh!
But regardless, to get right down to it I think it comes to this. To borrow from the Hindu....it's Turtles all the way down, and up, there Roger. BRILLIANT!

The supposed "Penrose rings" are large scale "random distribution" areas of very very small ( ± 0.00003 K) temperature differences in the cosmic microwave background (CMB). Best estimates are that 300,000 years had to pass before the universe experienced light and the CMB is a product of that time. There are NO rings, NO prior universe fingerprints except in Penrose aging mind.
Magnificent. Loved it!!!
since one of the arguments for dark matter is that its needed to provide the initial variation after the big bang, who else thinks the rest of his slides are about how these previous universe fluctuations might be dark matter?
Electrons, like atoms, and black holes, and the universe as a whole, are horn toroidal fluid vortices (hence "point-particles") in/of the single, scale-uniform 'super-fluid' medium (I call it the SUM, a.k.a. "space-time") whose self-relative motion (a.k.a. "acceleration"; "momentum"; "push") as vortices and waves, comprises the evolving (hence "time") structure of the universe and all of its content "physical objects". Therefore we can say that the "material universe" is 'pure motion' (primarily point-radial in trajectory). The Einsteinian "time dilation/ length contraction" principle applies to the SUM itself, meaning that its self-relative motion ("acceleration" as 'motion relative to itself') is the mechanism by which the otherwise absolutely homogenous SUM 'self-differentiates' into the structural diversity of the observable universe, including our own bodies.
Also, therefore, not only do massive objects "curve spacetime", massive objects ARE "curved spacetime". The inflow of the SUM equals the point-radial outflow "expansion" of the SUM compression wavefront that is the surface of the mass-object (e.g. the Earth). Ergo the "gravitational (and smaller scale) field(s)". Since SUM fluid vortices, and every complex manifold thereof, including ourselves, constitute 'I/O devices' (inflow/outflow; input/output; positive/negative; "yin/yang"; etc.), we can say that the physical universe is comprised by an otherwise, absolutely continuous SUM "simulating" (by means of its self-differentiating, self-relative motion) a "discrete particle" - based "material universe" as "a universal self-organizing network of distributed I/O devices" which are manifested in terms of their inter-communication by means of the specific sequence of SUM 'vibrational acceleration waves' traveling at the "constant, finite, but asymptotic limit for all mass-objects" speed of light which they emit and absorb. We "human beings" are momentum routers ("pushers" of "things") in that network. In order for there to be a "push", there must be a "something else" to "push against". "Yin/Yang". Consider that every "sensation" - i.e. that you are "conscious" of - is comprised of a "push" (or vibrational series of "pushes") at some scale, at some amplitude, in some 'direction', as a "transfer of momentum"; a displacement of a mass object from its otherwise geodesic path. So the "material universe" is apparently a self-configuring momentum-routing circuit /network. "Consciousness" is 'a self-configuring momentum waveform' in/of the SUM.
P.S. "Dark matter" is the SUM itself concentrated around its "material" vortices, and "dark energy" is its larger-scale flow.
@ @/@ They are being carried along by the outwardly expanding flow of the SUM (scale-uniform medium) itself from its horn toroidal fluid vortexual architecture "output". They are not, themselves "accelerating" (undergoing "proper acceleration") by means of an 'on-board' power supply. Thus, in this case, they are not moving "through space over time", they are moving "with space over time". Light waves are the universal 'CPU clock ticks' of 'time'. They make up the 'Cartesian coordinate system' of the 'space-time epic' in which we are taking place. ...
Call the Y axis "time", and the X axis "space". Let your eye be at 0 looking in the positive Y direction, and let any other detector be placed anywhere else along the X axis. The photon (or physical increment of "time") is propagating toward your eye, or other detector, as a spread-out 'shock wave' front, and collapsing point radially toward its detector, only being "detected" when the momentum (acceleration) pulse it is transferring through the SUM (scale-uniform medium, or "space-time") literally from its horn toroidal 'point' of origin is transferred to its corresponding destination point of detection.
The universe might be described as a 'self-calculating quantum computer'.

On that thing about E=hf=mc^2, since light has frequency and will exist in the distant future, doesn't that count as a scale of time?

Mind blowing, indeed. I've heard of it before now I got the chance to see it. But... if someone one could answer me. How about black energy, the apparent expansion and the fate of matter becoming photons, without counting for that black energy that we cannot describe yet?

Are we certain clocks don’t keep a universal time? Unedited are clocks not a measure of position?
My clock keeps a universal time. Others do not.
Yes, we are certain. Gravity, speed, and location over vast distances impact time, therefore, no clock, no matter how accurate, can ever be universal. In addition, cause and effect is limited by the speed of light, and as long as there is a cosmic speed limit time itself cannot be universal. So, it stands to reason that if time cannot be universal, clocks that tell time cannot be universal. Does that make sense?
Great lecture! I am still reading Emperors new mind.
I should read it. Been on my desk for the past 5 years
Clocks that beats once per eon- maybe you don´t need to wait them to break...
The idea of the the universe being perpetual could be part of our problem understanding the whole issue. What if their is no beginning or ending to the universe? The Universe just transitions between stages? If we do detect evidence of supermassive black hold decay from before the so-called Big Bang then how are we going to explain it? Interesting physics.
Is CCC different from a casual loop? Because an actual infinite that is past eternal is subject to the Grim Messenger paradox which is basically a philosophical argument against casual infinitism. Therefore, Im asking for more clarity on the meaning of cyclical in this hypothesis? Anyone care to explain.
It's in his book, Cycles of Time; he says CCC's infinite string of connected aeons is equivalent to a single aeon looping around to itself. He prefers the former solution, because of potential time-travel paradoxes in the looped version. There are however self-consistent versions without paradox, so Occam's razor probably cuts the other way..
@@hkjeldsen what former solution? What versions are self consistent? Causality can be a loop but time doesnt have to be. The GM paradox is against linear causality which is why I believe a causal loop is the only logical solution.
@@CMVMic Penrose prefers his infinite string solution over the equivalent loop, I meant. Self-consistent loop solutions follow Novikov's self-consistency principle; Deutsch has a version of self-consistent closed time-like loops in quantum computing, and Lloyd has a probably better post-selected version, and there are other approaches with self-consistent open time-like curves. Aaronson has shown that with access to a closed time-like curve, a Turing machine is as powerful as a quantum computer with access to same. I agree a loop is the best solution, and it solves a lot of other deep problems, as long as paradox can avoided by some self-consistency condition.
Roger Penrose always reminds me of Carl Friedrich Gauss.
They resemble each other physically but also in the topics they studied.
Cannot see the pictures on his screen.
Thankyou.
I can not seen the slight, why 😢😢😢
My theory is the first singularity was forced through first black hole to expand and then reach ultimum expansion which then recedes back into a singularity to be forced out of the black hole at the center to become the next universe .thus a perpetual universe.
Look for "Cosmological natural selection" by Lee Smolin which has a much more interesting hypothesis, similar to yours.
What forced the first black hole to expand. A Black hole by natural observations, does not self expand.
Logically, you are saying the first black hole expanded and reached ultimate expansion then receded again into a singularity, so where in this mess, do we live? Inside a black hole?
@@SpaceCadet4Jesus if you read it. I texted the singularity itself travels through the black hole which gives it the momentum the singularity needs to be released at the other end to become the universe...the singularity expands after it has been released from the black hole..
@@robynkulage4581 As far as I can tell, a singularity (if it truly exists) is the single point to which time/space can be condensed, which itself is the definition of a black hole. With that in mind, a singularity cannot travel through a black hole, because it IS the black hole.
It's like sticking your head up your bum and coming out a new person.
@@SpaceCadet4JesusI disagree that a singularity and black hole are the same just my opinion..

The problem lies in the nature of Time as a physical, material attribute and therefore what Reality, in itself, means
In an idealized far future hypothetical state of the universe in which there is nothing but photons, so no mass, and no space-time, does Penrose's theory imply that all the photons in the universe would effectively be superimposed into a single entity, and that this absolute idealized state is not a necessary precondition for being indistinguishable from the big bang, and the state gets close enough to initiate expansion before this idealized state is reached, thus introducing anisotropies from the remaining matter and/or photon distribution? If yes, it seems this superimposition of photons is not a collapse of space-time, but the rug getting pulled out from under the photons as space-time ceases to exist or have any arrows.
I have been afflicted with the idea that there could be a universal superimposed time frame in which time is speeding up over time universally, over and above the effects of mass and relative velocity on space-time, in other words, like the "rate" of time is always increasing but it is hard to detect because all clocks change right along with it. It would however manifest as increasing redshift with distance due to apparent lengthening in wavelength as measured with our faster present clocks, similarly to how expansion manifests as increasing redshift with distance. Some preliminary thought experiments make me think this superimposed increasing time rate would also tend towards fitting lensing and galactic rotation data which can also be explained in terms of dark matter and dark energy. Penrose's theory that an eventual universe with nothing but photons in it would at some point be indistinguishable from the big bang makes me wonder if said superimposed time compression, if a thing, could be tied to the mass/radiation ratio of the universe, so as time speeds up over time, and the balance shifts more and more to photons, a limit is reached where the direction and "rate" of the arrow of time concurrently cease to have any meaning, as the superimposed time quanta get smaller and smaller but don't see the horizon, like Escher's angels and devils.
I'm not smart enough to know if this superimposed universal time rate concept would be deemed preposterous nonsense or intriguing brainstorming by the average cosmologist, so I'm hoping somebody sciency will read this and give me a clue.
In an idealized far future hypothetical state of the universe in which there is nothing but photons, so no mass, no time, no space-time, no space, does Penrose suggest that all the photons in the universe would effectively be superimposed into a single entity, and that this absolute idealized final state is not a precondition for being indistinguishable from the big bang, that the state is close enough to initiate expansion before this idealized state is reached, thus introducing anisotropies from whatever mass remains? To what degree do the CMB anisotropies reflect seed universe matter versus seed universe photon distribution? Would it make sense to say this superimposition of photons is NOT like a collapse where all the photons end up in one spot, but more like "one spot" by not having dimensions simply "encompasses" all the photons that would otherwise have continued on their merry way if there were still some evaporating blackholes around?

I think this largely has to do with the fact that we can conceptualize gravitational waves as 4th dimensional. When we have a 2-dimensional plane of length and width, like a rigid sheet, influencing that plane with gravitational force, say by dropping a baseball on it, would allow for depth to occur. Gravitational waves on a 3-dimensional plane could send influence to the dimension above by the same principle. We may just be seeing 3-dimensional slivers of those 4-dimensional waves from black hole formations and collisions from other aeons, portions that are effectively "in frequency" with the 3 dimensional plane at that particular moment in time.
Does anyone know how to contact Roger Penrose, by email ideally?
Roger is really an excellent genius and the NobelPrize for his work was overdue 👍🏾🌏
Black Macro- and Micro- Holes are as well as Big- Bangs SINGULARITIES: Already defined by Karl Schwarzschild in 1916 mathematically and as a physical reality as well. Within the CENTER of Black- Holes are SINGULARITIES as we now since 1916. And we 'suppose', that there was ONE Big- Bang out of a SINGULARITY, where Time and Space were created 14 Billion Years ago. Roger Penrose is really a great Genius and his recent awarding with the Nobel Prize was overdue. HE is able to separate between the 'Beauty' of the Imagination of 'deep' Mathematics and the Existance of 'deep' Physical 'Reality'.... Respect ! And he concedes, that INFINITY exists within Mathematics - which is the most beautiful type of Philosophy - as well as in Physical REALITY. This gives me hope, that my Theory of an INFINITE Universe, which I call the INFINIVERSE really exists:
''Our INFINIVERSE is an INFINITE OVERALLPROCESS of an infinite simultaneous VARIATION of infinite many SINGULARITIES like Big- Bangs and like Black- Holes within an INFINITE CHAOTIC STRUCTURE of an INFINITE DIMENSIONAL MATRIX .''
Hard to understand, but that's our Physical Reality. I'm BertTheAce and I'm sure Roger Penrose can understand, what I mean. And this NEW Standard Model of Physics finally solves the inconsistency of 'Dark Matter' and 'Dark Energy' within the classical Standard Model of Physics. I did propose my INFINIVERSE- Theory to the scientific Springer magazine 'Nature' some months ago and may be it will be published soon.
I have been a fan of Sir Roger, from the time I was introduced to his connecting shapes. I never supported string theory or the big bang or dark matter. I like his train of thought here, but would substitute a torus a representational model.
Can someone explain how the squashing happens physically between aeons? I am a bit confused
As far as i understand it from other Prof Penrose's talks, there is no squashing. The 'expanse' at the End of this Universe will be the 'point' of a new Big Bang. It's a matter of scale according to Prof Penrose.
The point is:
There is no difference. You think, something is being smashed from cold and big to small and hot. But that‘s not the point. He says, that cold and big is being measured by mass. So cold and big can only be cold and big, when there is mass. Without mass, it is just radiation forever and even forever ist not the right word, because without mass there is no time. You ar loosing the dimensions at this point.
And this point, with having no mass and thus no time and only radiation, that‘s the point when you go from one angel in Eschers picture to the next. And the next aeon / universe / big bang starts. You will never know, how many angels there are before or after, and this doesn‘t even matter: There is a countless number in both directions. Call it god.
So that‘s how I personally understood Sir Roger.
@@dnswhh7382 great comment, thanks. Helped me understand it better. Can I ask, how does the big bang suddenly start again from the point of the newly thinned out void containing only photons/radiation. Like what would trigger/cause the new explosion of Big Bang? And how would galaxies and stars etc. again form?
@@unscrupulousyou The idea ist, there is no direct trigger. At this stage there are only photons, ‚forever‘. A photon does not experience time nor space, that’s a fact we know for sure. Photons are energy, that‘s also a fact. Now imagine the energy of the entire universe in ‚no space‘ (yet) at no time, what would you call that? Well, that‘s what we would today call our ‚Big Bang‘. The idea is, you are loosing space and time at the end (because only mass experiences space and time, but there is no mass anymore) and when this happens, you only have energy. A lot. But no time and no space, that’s ‚forgotten’. And then (if I may say ‚then’, which is a timely expression) the energy starts all over, creates mass (as energy can be transformed into mass and vice versa), with mass time and space again comes into existence and the next big bang start the new universe. Like the beat of an ever pumping heart, if you will. Well, that‘s just my romantic thought. Penrose theory has not been proven so far. Maybe it even cannot be verified at all. But I like it anyway.
@@dnswhh7382 thanks man. Amazing explanation! What's the process by which energy can change into matter? If you've got a spare minute lol
Roger Penrose is a powerhouse of geometry and physics, past and present (time invariant, of course)!
Can someone please help me understand
1. Looking for evidence that the universe has been here before
2. Cosmic background radiation is a sign
3. They needed to do tests to show confidence ( for what? Lost here)
4. Final note of the results, what was the 99% confidence showing ?
Thanks!
1. Scientific evidence that the universe has been here before - NONE.
2. Cosmic background radiation is a sign - IT IS. It's a sign of miniscule temperature variations from the opaque plasma(?) at a point approximately 300,000 years after the Universe's rapid expansion when light was finally able to stably form and function.
3. A confidence level represents the degree of uncertainty associated with a confidence interval, usually based on 95%. The higher the confidence level, the less uncertainty is associated with the confidence interval's estimation. Testing and repeated testing helps place the confidence level at a particular value.
4. The 99%+ confidence comes from a co-authored paper, titled "Apparent evidence for Hawking points in the CMB Sky", by Daniel An, Krzysztof A Meissner, Paweł Nurowski, Roger Penrose. In that paper, Penrose refers to Table 1 (which for unknown reason he changes the title of), which should read "Table 1. Number of artificial maps outperforming the real Planck 70 GHz map."
Calculations were performed both for the real maps as measured by WMAP and Planck (70 GHz, SMICA, SEVEM...) and, initially, for 1000 (then 9000) artificial maps generated with the observed CMB power spectrum.
To oversimplify a complex comparison paper, Are there identifiable presences of anomalous energetic small circular regions in the CMB sky map or is it just noise or pattern seeking?
A table of observed Planck and WMAP values (5 tables of values are in the paper, Penrose only shows one) are compared with an artifically generated map generated from observed CMB power spectrum. Penrose supported paper is saying the artifically generated map makes identifications of these tiny regions greater than the 99 percentile range of confidence. So they do seem to exist both by Penrose and Planck data, although the interpretation as to the meaning is left in the readers mind.

Is the ring of galaxies recently discovered associated with the rings mentioned by Pfr. Penrose?
Here Here!!!
Fun to think about, where's the observational evidence?
I got lost with where does the matter come from in the new eon. How does the transition between just photons and matter happen? Did I miss something?
Yes you missed the essence.
There is no beginning and no end, no past or future, as both conjugate at the ephemeral sequence of Creation, Evolution and Entropy.
@@edmondcohen2300thanks for clarifying. That was my sticking point too. If there is no explosion of matter again from one aeon to the next, does that mean the only matter in any aeon of the universe are the structures we see now in our current aeon? Galaxies, etc.
One can hear the universe put-putting across eternity like a cosmic motor boat.
What a genius, to put it mildly.
No beginning no end only change
Well spoken man..
Whats with the small screen
Reminds me of Georg Cantor's infinite sets...
How is that publishing video was 2019 but the Nobel prise is 2020?
UA-cam is messing with us!
It seems as though an expanding and increasingly colder universe would lose entropy rather than its increasing; that would imply that a big bang began at maximum entropy, considering heat and pressure and mass all at a max, as with potential energy; and yet expansion implies an increasing number of mass objects within a given space, so wouldn't that increase entropy?
I surprised at how much I agree with this.
I had the cones together so they were square.
Wish camera would zoom to his drawings
I equate the graphical and artistic genius of ESCHER to the mathematical genius of Sir Roger. What a team :-)! Peace.
I don't have a problem with conformal part. It is cyclycal part that I don't get. What caused the big bang and why it seems cyclical every Google year?
What ever happened at every big bang can happen at any interval. It may have something to do with the low probabliy of the event but then what is the probablity is determined by?
You're a Crypto Christian
@@NoOne-tg9tk You're a Crypto Troll and Spammer.
If light photons have no mass it is said they do not experience time so why does light take so long to reach us if bound by the speed of light
Could that TV be any smaller?
This might sound mad, but could it be possible that our observable universe is actually the interia of a black hole? .... perhaps the missing matter and energy are outside our host black hole?
I have a question.
Fascinating and provocative! Also, I've always loved his - diagrams is too clinical a term; visualizations, of what he's describing. You can find them in his books,too, unfortunately not in color. So according to this model, it's not turtles all the way down (and up), but conformal transformations! Much easier on the turtles.
Ah! So it's Turtles. All the way down?
haha. Or..."incredibly complex geometry" all the way down!
Infinite cyclical time periods consisting of a Big Bang and a Big Crunch without any beginning or end is a well known concept from the Vedas. One such cycle is known as Brahmas Day / Night each consisting of 4.32 billion earth years. Very interesting that Penrose is coming to similar conclusions.
The stretching of univers is necessity..because space time is like stretched rubber band due to this gravity comes along.
@ 25:56 that pissed off looking kuia on the marae when the kaumatua is droning on and on holding the hangi up.
Mass isn't removed from the universe by black holes, the mass is in the black hole, which is in the universe. I also don't understand how the photons are supposed to have escaped the black holes when they've swallowed everything else, they gobble up light almost as easily as matter. I love Roger Penrose, and I've always believed in an oscillating universe since I was about ten years old tbh, but I'm not super convinced about the details here. Dark matter as a sort of echo of the previous universe is a fun idea though!
The future.
