Penrose has a compelling theory - in the very distant future all matter would have evaporated from black holes and the universe will consist of photons which have no mass. If there is no mass in the universe, size and time become meaningless. The universe becomes a singularity to start the next eon. This is difficult to get your mind around, but makes more sense than Inflation. For the first time I have found a reasonable explanation of what came before the big bang. Well done Roger.

At the end there will be photons, m=0 and time stops. How these photon fields get together may have a better explanation in the big bounce, (Ashteker, Rovelli, Lee Smolin-QLG).
If Universe happened once it can and does happen again. I have wondered about what Roger is talking about many years before it became a topic and I imagined floating around seeing no mass but not being part of it but wondered if no mass then big doesn't "know" its big it can be big and small, its equivalent. It has a name called Conformal Cyclic Cosmology...now I know...so my hunch was right...
Without getting to ahead of ourselves in the distant future, the Eternal Now w/mass and gravity highlights a beautiful scale invariant which continues the black hole singularity from the big bang to the Maximus Universe.
Meh. I came up with the exact same idea several years ago. I was considering what happens to the strong interaction as the dark energy ramps rather than what happens to the photons and black holes. I expect interesting effects as electromagnetism and strong interactions crossover as modified by DE. The black holes are boring. They just evaporate. The forces are interesting.
I've been watching him present this theory over and over. I'm starting to think that this could be the best explanation we've ever had. I bet someday he will be looked back on as a genius for this.
This is the first time that I've heard Professor Penrose mention the steady state theory. But is that the nail in the coffin for the big bang? Staying tuned in.
His hypothesis can be viewed as an oscillating theory, hence potentially frequency driven given that mass is removed. Which when extrapolated, would remove a barrier between Relativity and quantum (not all, just one, that of size/distance). The man is brilliant.

Gluing Noncommutative Twistor Spaces Matilde Marcolli, Roger Penrose We describe a general procedure, based on Gerstenhaber-Schack complexes, for extending to quantized twistor spaces the Donaldson-Friedman gluing of twistor spaces via deformation theory of singular spaces. We consider in particular various possible quantizations of twistor spaces that leave the underlying spacetime manifold classical, including the geometric quantization of twistor spaces originally constructed by the second author, as well as some variants based on noncommutative geometry. We discuss specific aspects of the gluing construction for these different quantization procedures.
I feel he is correct about the microwave background radiation needs more in-depth study, like are it really about temperature alone or do it have a structural importance. I kind of like this idea that Hawking points is actually black holes that forms early primeval black holes to kickstart formation of galaxies and stars and then star continues this process to help making even more stars and heavier elements I don’t agree on, that black holes is only devouring monsters only. I believe black holes are kind of engines that makes our universe look like it is today and kind of switches of the light, when its time for new Aeon to do its big bang thing. Anyway our universe seams young and not ancient at all. So not the first one to exist nor the last one. Please comment, what are you views on this subject’s.

Be afraid of that electronic consciousness: it never had the opportunity to evolve basic sociality, what took us millennia probably, the most normal thing for such advanced general AI without social evolution but with "superpowers" (at calculating, focusing, etc.) is that it will be a monster and almost certainly destroy Humankind.
@@chunglee7531 we do live in a 'holographic' universe. in essence, anything that is created in our universe, a 3D DIMENSION that is, is a form of reverberation of energy manifested. there are also other universe with a different reverberation manifested, leading to multiverse theory.
could gravity have to do with entanglement ? Early Universe was uniform and entangled . Black holes have higher gravity because its a big mass of entangled information/particles ?
How about if light reffraction has to do with gravity as well entanglement ? it does to me if we see the universe as 3 state matter found in that is PLASMA or stars that we could say is the neutral state, stars emite HOT LIGHT that is the second state that as it goes up out the system it will find electromagnetism that will make some of this light to returne back some light will make it through out the electromagnetism levels but sooner or latter light will find more electromagnetic halos that will trap this light and so do a recycle ones more. - The light refracted as it reffracts it gives out some heat so it becomes heavier than vapor so pushes down and produces gravity in a down push to a point that it neutralyzes with the out put of power of expantion from say our sun so it then takes the form of an UFO CRAFT as one light pushes up and the other down so is same thing that may bend light coming from outer stars, this 2 forces do kind of make look the stars or galaxies just like a rhomboid in a kind of magnetified glas.
Einstein would be extremely spooked at your suggestion... literally. He didn't like entanglement. However I'd say that entanglement overruling the arrow of time, as in the DCQE experiment, strongly suggests that it can be explained precisely via General Relativity (as photons do not experience time, proper or "subjective" time, at all), adding thus fuel to what Penrose says at the end about quantum mechanics needing a good revision, while GR remains core.
this is probably a dumb question, but how in this model does the universe become reheated, undergo (apparent) expansion & symmetry breaking, etc.? is it a simple fact of the distant future becoming essentially massless and thus a singularity of sorts? i really like the idea but i can't wrap my head around this part of it.
Size doesn't matter is a core element in his theory. Any black hole does the job. I think that's the idea: white holes are new universes, new big bangs...
Think about movement produces heat. The BB rather unfortunately named. It is more of a start of movement/expansion of singularity. Think about this: you breath in cold air, your breathing stops for a second, and you breath out. Incoming air colder, at stop it worms and start to move in opposite direction, outgoing air is much warmer.
@@LightshamanaDhyana Your example is almost certainly irrelevant: you can actually inhale air hotter than your body, it may feel uncomfortable but under 50C or so you can. In such cases the exhaling air is colder than the environment's. We don't breath because of temperature, we breath by mechanical pump, unconscious as it may be.
The problem with this theory is that Penrose can't explain what happens, just that photons through lack of sizing become the new big bang. I came up with this exact same theory in my early teens without any external input, just from knowing scientific basics at the time. But I don't think it's the way forward. I tend to believe that black holes eventually create new universes, and what we experience isnt a big bang but a big collapse, where the black hole 'explodes' but creates a shrinking universe inside, to us this looks like expansion but it is actually like a jar growing in size internally, but without the jar changing.
This hypothesis is solid. Solves a lot of problems. A googol years in the absence of clocks is instantaneous. In fact a googol years without a conscious observer to appreciate the passage of time is irrelevant. How long was the period before you were born? To you, the Universal observer, this period has no meaning. Subsequently, after your consciousness expires, time will cease to have meaning to you. This is the basic concept behind this hypothesis. However this hypothesis includes all observers, i.e. all particles of mass.
So Penrose either assumes that all matter ends up in black holes, which is unlikely to be true, or that all matter eventually decays - and proton decay has not yet been shown.
It sounds like a reheated steady-state theory ... don’t see how the physics at the big-bang can be stitched into the physics of an expanded universe. The two are quite different and what happens to the arrow of time ... why don’t we see the reverse of Penrose’s process?
He noted that the reverse wont be possible becouse in his model imformation swallowed by black hole singularity's is lost forever, quite fitting actually, to erase causality at the end of one aeon, that way the new aeon starts out fresh and is not simply a determenistic process defined by its predecesseors.
EM ENERGY along with the vacuum of space together control the mechanics of the universe and it's expansion. Ongoing creation of stars and their planets is happening throughout the universe and the hugh vacuum of infinate space is effecting the expansion of the universe. I can't see the neccessity of a BIg Bang except to deny the need for a Creator

The universe is clearly ‘sock shaped’ it turns itself (and time) inside out between each Eon. Nature is simple and beautiful… not clumsy cones like this. The Big Bang and the artificial intelligence explosion are the same event happening on each side of each universe/simulation
Pretty sure Zizec was asking one of the questions at the end of the lecture. Lol. The one about the universe loosing track of time and whether or not it was analogous to a tree falling over in a forest with no one around to hear it.
A universe comprising solely black holes and photons would be timeless. The duration over which a black hole would be effectively infinite in that there would be no other events to which to compare. I fail to see how the 'time' for ultimate blac holes to evaporate can be "physics". Is the 'bang' instantiated when the last boson passes over the universe's light horizon?
I'm not a physicist nor a mathematician. From what I understood Mass consists of particles vibrating at certain frequencies with high precision like a clock, hence time is brought to us.
Mass somehow (how?) causes space-time to curve inwards (what we usually call "gravity") and that affects more dramatically time for all I know. Anyhow just browse videos and other materials on General Relativity and clocks and you should get it eventually, at least at a basic level of understanding.
Does this mean that all previous eons would fit within a microscopic space of the current eon? That space between two points is not just mathematically infinite, but physically infinite?
He says that the eons are cyclical but my self dont see them such due that dont see how he sees a cycle, water cycle we have the sea water that goes up as vapor and comes as rain. - do you see any cycle in the eons?
@@SernasHeptaDimesionalSpace - Those kind of cycles you mention are thermodynamically consistent but for Penrose's theory, thermodynamics do not matter once you reach the singularity level (it's only an emergent property and not fundamental to physics as such). So they are not directly comparable: their cyclical nature is because they repeat again and again and again ad nauseam (ad infinitum to be more neutral).
"Does this mean that all previous eons would fit within a microscopic space of the current eon?" It does not. The eons looses all distance and time measurement at the "only photons phase". You can not compare size or time between eons because you do not have matter to compare it with. It is even more fundamental .... there is no such thing as distance anymore as soon as everything (the photons left) is moving at the speed of light.
I sure quantum mechanics is the past obeying the law of conservation of information and they are technically ghost participial. Like a hard drive that has bin formatted that information is still on the hard drive
Does anyone consider that the cycles might loop back around like a hyper toroid? So instead of multiple cycles in a straight line, each compression returns to the initial expansion, in an infinite progression. Each instance leads to a superposition of Many Worlds branching and expanding conformally. All of this happening in a sense simultaneously when viewed from an angle where the entirety of spacetime and its branches can be seen at once. I'm interested in the geometry of that object.
I have no idea about what exactly you mean, however I just watched another conference by Penrose in which (near the beginning) he shows an image that is rather toroidal, you may be interested in that. This one: ua-cam.com/video/hr_5QzbUqBw/v-deo.html
@@ivocanevo that is exactly my thought, the toroidal structure would account for the expanding universe easily, also for spin, and dozens of other things.
@@LuisAldamiz oh yeah, that twistor lecture. Penrose is such a genius. I may watch that again, but I'm pretty sure we couldn't connect any of that with what I was saying. Which is: in higher dimensions the beginning of one era could be the beginning of the next. If there's anything to it, I'm sure that Penrose would have considered it, as that's just the sort of thing he seems to like. I suppose it could be in his secret speculative notes. That would be validating for me, but I'm probably just on the wrong track.
What? What do you mean by "mirror symmetric"? A singularity in a mirror (assuming photons could escape to form an image, which they can't) would be a mirrored singularity. Internally, as supposedly perfectly homogeneous, singularities must have p (mirror-like) symmetry anyhow in all three spatial axes, just like a sphere.
Penrose emphasizes that time is ASYMMETRIC. It's called noncommutative phase or quantum algebra as noncommutative geometry. Penrose admits he's not very good at that type of math.
@@voidisyinyangvoidisyinyang885 - Time seems quite assymetric indeed: the past and the future are not the same, the future is always open, the past is always frozen. But anyhow that would be T symmetry, which is not the same as P symmetry ("mirror" symmetry).
@@LuisAldamiz yes Penrose is talking about the massless universe of spacetime particles but still relativistic mass of pure radiation so there is no invariant rest mass as inertial mass - only relativistic gravitational mass based on noncommutative frequency inverse to time. So he uses the de Broglie-Einstein relation which is the same as de Broglie's Law of Phase Harmony. So essentially time is asymmetric as entropy only AFTER we assume spacetime causation but "primordial time" as a pure momentum energy that is still relativistic mass and is asymmetric as noncommutative phase. So there is reverse time and negative frequency at the same time as positive frequency and positive time. At the speed of light it is nonlocal causation from the perspective of the light being turned around as wavelength but light has a hidden "supermomentum" or relativistic mass that is noncommutative geometry. B.G. Siddharth who predicted the dark energy accelerating expansion of the universe - he goes into this also - as does Paul S. Wesson (5D black hole universe model). Or you can read Gerard 't Hooft's article "Light is Heavy" - for details - with Martin van der Mark. So the "mirror" symmetry is maintained in the zero point rest frame but the noncommutative phase is asymmetric time-frequency energy. It can only be measured "after" the fact in terms of spacetime linear causation due to the Uncertainty Principle from time-frequency uncertainty. So this means the information exists as pure energy before spacetime so it is energy as frequency-information inverse to time. So that means at the zero point in spacetime there ALREADY is a "fifth force" as noncommutative phase spin energy - a new "causative force" as Basil J. Hiley calls it (he's buddies with Penrose and Hiley helped Penrose coin the term Twistor).... A good example of this are the "Negaparticles" discovered by Yakir Aharonov's research group using "weak measurement" in quantum nonlocal entangled photon experiments. Or also the Delayed Choice Eraser Experiments - promoted by Olivier Costa de Beauregard and now tested - both these experiments PROVE that the past can indeed be changed. thanks.
The procedure taught in Geometrical Drawing and Perspective Projection Techniques begins with a symbolic Eye of the Observer and various axes of 3D-T in the picture plane Perspective vanishing-into-no-thing within the Observer's plane, and if we apply Newtonian Fluxion-Integral Temporal superposition Calculus, (only the names are changed, the logarithmic temporal vector sync-duration functions remain components of orthogonal-normal axial-tangential infinite e-Pi-i relative-time-timing numberness). The Observer's eye lenses are "where it all comes together" in 1-0-infinity instantaneous trancendental i-reflection containment, a thought experiment in eternal continuity. Every body knows the existence-experience in some degree of being here-now in pulse-evolution differentiates integrated Quantum Chemistry. Assembling abstract self-defining coherence-cohesion objectives in AM-FM Timing-spacing coordination alignments require a detailed training program to develop from reactive to apply projection-drawing techniques to not only use this GD&P Actuality reference frame to produce an overall coherence, but also QM-TIME cohesion of holographic resonances in time duration timing modulation interference positioning, in this Perspective Principle. The time has come, eternally, to review, reiterate and reset orientation to the state of Math-Physics in the Actuality of QM-TIMESPACE Holographic Imagery.
The sound is just awful, unlistenable almost, although weirdly it's much better during the 12 minutes of opening waffle.. this always happens with Penrose, its like modern equipment is not set up for his style of anything (at least they got him an OHP, but still, the sound..! it's important!) * It sounds like the mic is on the table or something, it picks up the flicking of sheets a lot.. I think you should have given him a Britney mic, for future reference
I marvel at this intellect; yet, it doesn’t make it so just because the late Steven Hawking theorized “Hawking Areas,” Academia are a closed group and they get their papers published only when in lock-step agreement. Write something contrary snd watch your grant money get jerked.
What makes you think he is absent minded???? Given his very poor eyesight - not to mention his age - he seems to me to be incredibly present minded :-)
Expanding space is naked empire. Nucleus of atoms expanding and recycling expanding pushing force which have example nature of expanding light. Expanding light waves is dark pushing force for us, but because we can register photons, we know there is also waves. Expanding lights interactive with eachother and thats why old light is redshifted light cosmologys way. Also expanding light moving faster and faster same way what matter and light expanding. That explain 1. Bending light near star and galaxy 2. Cosmologys way redshifted light 3. "Gravity" redshifted light 🤔

The main problem with modern physics,lies in their attempt to know everything, such as the theory of every thing. I find it very disturbing. As I see it, besides being observable and verifiable, belief in independence of mathematical algorithm holds the key that explains human limitation and divine design. In our galaxy millions of BH roam around at great speed, yet not one came near our solar system in 4.5 billion years wiping out everything, protecting us evolve life and consciousness on earth with perfection and with probability one, winning millions of lotteries over billions of years (like the BH we missed). Mankind will never know the algorithm of the universal quantum computing function of Maldacena's conjecture.
Black holes don't generally wipe out everything, they are just like any other object of their mass (i.e. a sizable star in the case of stellar mass BHs), just that pitch black instead of shiny. Their pop fame as hungry monsters is all kinds of unjustified, they generate gravitational attraction just as any other thing floating out there.
I hate to have to correct Penrose but "eon" is from Ancient Greek,and it means century,100 years. Thats why in Greek you write 21st century as 21ος Αιωνας ,(Eonas). It does carry the meaning of a long period of time if you use it broadly speaking. I d expect a scientist of his caliber to have done some research(or just ask friends,it s not that uncommon knowledge) before making such claims. It doesn make the rest of his claims really not that trustworthy...
The word aeon /ˈiːɒn/, also spelled eon (in American English), originally meant "life", "vital force" or "being", "generation" or "a period of time", though it tended to be translated as "age" in the sense of "ages", "forever", "timeless" or "for eternity". It is a Latin transliteration from the koine Greek word ὁ αἰών (ho aion), from the archaic αἰϝών (aiwon). In Homer it typically refers to life or lifespan. Its latest meaning is more or less similar to the Sanskrit word kalpa and Hebrew word olam. A cognate Latin word aevum or aeuum (cf. αἰϝών) for "age" is present in words such as longevity and mediaeval.[1] Although the term aeon may be used in reference to a period of a billion years (especially in geology, cosmology and astronomy), its more common usage is for any long, indefinite period. Aeon can also refer to the four aeons on the geologic time scale that make up the Earth's history, the Hadean, Archean, Proterozoic, and the current aeon, Phanerozoic. en.wikipedia.org/wiki/Aeon
You are wrong. From Wikitionary: αἰών • (aiṓn) m (genitive αἰῶνος); third declension lifetime generation a long period of time, eon, epoch, age the current world eternity
They tell as of BH spining nicely and jet we see stars near the BH that go in many orbits, some go right some go left some go up some go down so why is that?

Most things are habit until it ends.
could gravity have to do with entanglement ? Early Universe was uniform and entangled . Black holes have higher gravity because its a big mass of entangled information/particles ?
How about if light reffraction has to do with gravity as well entanglement ? it does to me if we see the universe as 3 state matter found in that is PLASMA or stars that we could say is the neutral state, stars emite HOT LIGHT that is the second state that as it goes up out the system it will find electromagnetism that will make some of this light to returne back some light will make it through out the electromagnetism levels but sooner or latter light will find more electromagnetic halos that will trap this light and so do a recycle ones more. - The light refracted as it reffracts it gives out some heat so it becomes heavier than vapor so pushes down and produces gravity in a down push to a point that it neutralyzes with the out put of power of expantion from say our sun so it then takes the form of an UFO CRAFT as one light pushes up and the other down so is same thing that may bend light coming from outer stars, this 2 forces do kind of make look the stars or galaxies just like a rhomboid in a kind of magnetified glas.
Einstein would be extremely spooked at your suggestion... literally. He didn't like entanglement.
However I'd say that entanglement overruling the arrow of time, as in the DCQE experiment, strongly suggests that it can be explained precisely via General Relativity (as photons do not experience time, proper or "subjective" time, at all), adding thus fuel to what Penrose says at the end about quantum mechanics needing a good revision, while GR remains core.
Do 'Black Wholes' Generally Retain The Information They Interpret?
What Type Of Internal Structure Is Most Likely Given The Constraints?
this is probably a dumb question, but how in this model does the universe become reheated, undergo (apparent) expansion & symmetry breaking, etc.? is it a simple fact of the distant future becoming essentially massless and thus a singularity of sorts?
i really like the idea but i can't wrap my head around this part of it.
Size doesn't matter is a core element in his theory. Any black hole does the job. I think that's the idea: white holes are new universes, new big bangs...
Think about movement produces heat. The BB rather unfortunately named. It is more of a start of movement/expansion of singularity.
Think about this: you breath in cold air, your breathing stops for a second, and you breath out. Incoming air colder, at stop it worms and start to move in opposite direction, outgoing air is much warmer.
@@LightshamanaDhyana Your example is almost certainly irrelevant: you can actually inhale air hotter than your body, it may feel uncomfortable but under 50C or so you can. In such cases the exhaling air is colder than the environment's. We don't breath because of temperature, we breath by mechanical pump, unconscious as it may be.
The problem with this theory is that Penrose can't explain what happens, just that photons through lack of sizing become the new big bang. I came up with this exact same theory in my early teens without any external input, just from knowing scientific basics at the time. But I don't think it's the way forward. I tend to believe that black holes eventually create new universes, and what we experience isnt a big bang but a big collapse, where the black hole 'explodes' but creates a shrinking universe inside, to us this looks like expansion but it is actually like a jar growing in size internally, but without the jar changing.
This hypothesis is solid. Solves a lot of problems. A googol years in the absence of clocks is instantaneous. In fact a googol years without a conscious observer to appreciate the passage of time is irrelevant. How long was the period before you were born? To you, the Universal observer, this period has no meaning. Subsequently, after your consciousness expires, time will cease to have meaning to you. This is the basic concept behind this hypothesis. However this hypothesis includes all observers, i.e. all particles of mass.
Yes I was thinking the same thing. The amount of time it takes is irrelevant a googol years a googolplex doesn't matter.
So Penrose either assumes that all matter ends up in black holes, which is unlikely to be true, or that all matter eventually decays - and proton decay has not yet been shown.
It sounds like a reheated steady-state theory ... don’t see how the physics at the big-bang can be stitched into the physics of an expanded universe. The two are quite different and what happens to the arrow of time ... why don’t we see the reverse of Penrose’s process?
He noted that the reverse wont be possible becouse in his model imformation swallowed by black hole singularity's is lost forever, quite fitting actually, to erase causality at the end of one aeon, that way the new aeon starts out fresh and is not simply a determenistic process defined by its predecesseors.

@@MohsinRaza-eg8xn Any thing that could be light for me must to come from mass, how can there be a THING with out mass?
@@SernasHeptaDimesionalSpace Before you ask "how can something have no mass?" you should start with "what is mass and why does it exist?"
Photons don’t have mass @@SernasHeptaDimesionalSpace
A universe comprising solely black holes and photons would be timeless. The duration over which a black hole would be effectively infinite in that there would be no other events to which to compare. I fail to see how the 'time' for ultimate blac holes to evaporate can be "physics". Is the 'bang' instantiated when the last boson passes over the universe's light horizon?
Penrose emphasizes that time is asymmetric due to noncommutative phase.
@@voidisyinyangvoidisyinyang885 I need to read more to grok that... maybe more than my brain can digest.
What is relationship between time and mass
I'm not a physicist nor a mathematician. From what I understood Mass consists of particles vibrating at certain frequencies with high precision like a clock, hence time is brought to us.
Mass somehow (how?) causes space-time to curve inwards (what we usually call "gravity") and that affects more dramatically time for all I know.
Anyhow just browse videos and other materials on General Relativity and clocks and you should get it eventually, at least at a basic level of understanding.
It seems that at least three tug a wars all end up at the same question with calculations, glueing and different methods to me.
Why we take light cone opposite. Why it is not closed
If initial constraints vary light cone be any angle
What is anti of singularity
Penrose currently has par in theoretical physics.
Does this mean that all previous eons would fit within a microscopic space of the current eon? That space between two points is not just mathematically infinite, but physically infinite?
He says that the eons are cyclical but my self dont see them such due that dont see how he sees a cycle, water cycle we have the sea water that goes up as vapor and comes as rain. - do you see any cycle in the eons?
@@SernasHeptaDimesionalSpace - Those kind of cycles you mention are thermodynamically consistent but for Penrose's theory, thermodynamics do not matter once you reach the singularity level (it's only an emergent property and not fundamental to physics as such). So they are not directly comparable: their cyclical nature is because they repeat again and again and again ad nauseam (ad infinitum to be more neutral).
"Does this mean that all previous eons would fit within a microscopic space of the current eon?"
It does not.
The eons looses all distance and time measurement at the "only photons phase". You can not compare size or time between eons because you do not have matter to compare it with.
It is even more fundamental .... there is no such thing as distance anymore as soon as everything (the photons left) is moving at the speed of light.
I sure quantum mechanics is the past obeying the law of conservation of information and they are technically ghost participial. Like a hard drive that has bin formatted that information is still on the hard drive
49:20 diagram is fascinating
What compress to black hole into singularity. What happened thermodynamics laws
He rejects them being fundamental, I agree: they are emergent properties only.
@@LuisAldamiz which make perfect sense, there is no disorder without discrete entities in homogen structure .
Someone-yes, it was the late genius Stephen Hawking- declares that.Black holes evaporate and disappear and that is dispositive?
#AwarenessConsciousness
Roger Penrose is the closest we will see of god
Does anyone consider that the cycles might loop back around like a hyper toroid?
So instead of multiple cycles in a straight line, each compression returns to the initial expansion, in an infinite progression. Each instance leads to a superposition of Many Worlds branching and expanding conformally. All of this happening in a sense simultaneously when viewed from an angle where the entirety of spacetime and its branches can be seen at once.
I'm interested in the geometry of that object.
No one is probably going to care that I said this. I'll respond to replies though.
I have no idea about what exactly you mean, however I just watched another conference by Penrose in which (near the beginning) he shows an image that is rather toroidal, you may be interested in that. This one: ua-cam.com/video/hr_5QzbUqBw/v-deo.html
@@ivocanevo that is exactly my thought, the toroidal structure would account for the expanding universe easily, also for spin, and dozens of other things.
@@LuisAldamiz oh yeah, that twistor lecture. Penrose is such a genius. I may watch that again, but I'm pretty sure we couldn't connect any of that with what I was saying. Which is: in higher dimensions the beginning of one era could be the beginning of the next. If there's anything to it, I'm sure that Penrose would have considered it, as that's just the sort of thing he seems to like. I suppose it could be in his secret speculative notes. That would be validating for me, but I'm probably just on the wrong track.
So many people with a ticket for the bus trip. It just shows people love to think.
In this consideration only Black holes not consideration of White hole, dark matter is not consideration
12:30 roger finally starts. I hate long introductions
You cold be 30 years old and still turn doorknobs back wards with a deep mind.
What is mirror SYMERTIC of singuraity.
What? What do you mean by "mirror symmetric"? A singularity in a mirror (assuming photons could escape to form an image, which they can't) would be a mirrored singularity. Internally, as supposedly perfectly homogeneous, singularities must have p (mirror-like) symmetry anyhow in all three spatial axes, just like a sphere.
Penrose emphasizes that time is ASYMMETRIC. It's called noncommutative phase or quantum algebra as noncommutative geometry. Penrose admits he's not very good at that type of math.
@@voidisyinyangvoidisyinyang885 - Time seems quite assymetric indeed: the past and the future are not the same, the future is always open, the past is always frozen.
But anyhow that would be T symmetry, which is not the same as P symmetry ("mirror" symmetry).
@@LuisAldamiz yes Penrose is talking about the massless universe of spacetime particles but still relativistic mass of pure radiation so there is no invariant rest mass as inertial mass - only relativistic gravitational mass based on noncommutative frequency inverse to time. So he uses the de Broglie-Einstein relation which is the same as de Broglie's Law of Phase Harmony. So essentially time is asymmetric as entropy only AFTER we assume spacetime causation but "primordial time" as a pure momentum energy that is still relativistic mass and is asymmetric as noncommutative phase. So there is reverse time and negative frequency at the same time as positive frequency and positive time. At the speed of light it is nonlocal causation from the perspective of the light being turned around as wavelength but light has a hidden "supermomentum" or relativistic mass that is noncommutative geometry.
B.G. Siddharth who predicted the dark energy accelerating expansion of the universe - he goes into this also - as does Paul S. Wesson (5D black hole universe model). Or you can read Gerard 't Hooft's article "Light is Heavy" - for details - with Martin van der Mark.
So the "mirror" symmetry is maintained in the zero point rest frame but the noncommutative phase is asymmetric time-frequency energy. It can only be measured "after" the fact in terms of spacetime linear causation due to the Uncertainty Principle from time-frequency uncertainty. So this means the information exists as pure energy before spacetime so it is energy as frequency-information inverse to time. So that means at the zero point in spacetime there ALREADY is a "fifth force" as noncommutative phase spin energy - a new "causative force" as Basil J. Hiley calls it (he's buddies with Penrose and Hiley helped Penrose coin the term Twistor)....
A good example of this are the "Negaparticles" discovered by Yakir Aharonov's research group using "weak measurement" in quantum nonlocal entangled photon experiments. Or also the Delayed Choice Eraser Experiments - promoted by Olivier Costa de Beauregard and now tested - both these experiments PROVE that the past can indeed be changed. thanks.

The sound engineer needs sacking.
The procedure taught in Geometrical Drawing and Perspective Projection Techniques begins with a symbolic Eye of the Observer and various axes of 3D-T in the picture plane Perspective vanishing-into-no-thing within the Observer's plane, and if we apply Newtonian Fluxion-Integral Temporal superposition Calculus, (only the names are changed, the logarithmic temporal vector sync-duration functions remain components of orthogonal-normal axial-tangential infinite e-Pi-i relative-time-timing numberness).
The Observer's eye lenses are "where it all comes together" in 1-0-infinity instantaneous trancendental i-reflection containment, a thought experiment in eternal continuity. Every body knows the existence-experience in some degree of being here-now in pulse-evolution differentiates integrated Quantum Chemistry.
Assembling abstract self-defining coherence-cohesion objectives in AM-FM Timing-spacing coordination alignments require a detailed training program to develop from reactive to apply projection-drawing techniques to not only use this GD&P Actuality reference frame to produce an overall coherence, but also QM-TIME cohesion of holographic resonances in time duration timing modulation interference positioning, in this Perspective Principle.

The main problem with modern physics,lies in their attempt to know everything, such as the theory of every thing. I find it very disturbing. As I see it, besides being observable and verifiable, belief in independence of mathematical algorithm holds the key that explains human limitation and divine design.
In our galaxy millions of BH roam around at great speed, yet not one came near our solar system in 4.5 billion years wiping out everything, protecting us evolve life and consciousness on earth with perfection and with probability one, winning millions of lotteries over billions of years (like the BH we missed). Mankind will never know the algorithm of the universal quantum computing function of Maldacena's conjecture.
Black holes don't generally wipe out everything, they are just like any other object of their mass (i.e. a sizable star in the case of stellar mass BHs), just that pitch black instead of shiny. Their pop fame as hungry monsters is all kinds of unjustified, they generate gravitational attraction just as any other thing floating out there.

I hate to have to correct Penrose but "eon" is from Ancient Greek,and it means century,100 years.
Thats why in Greek you write 21st century as 21ος Αιωνας ,(Eonas).
It does carry the meaning of a long period of time if you use it broadly speaking.
I d expect a scientist of his caliber to have done some research(or just ask friends,it s not that uncommon knowledge) before making such claims.
It doesn make the rest of his claims really not that trustworthy...
The word aeon /ˈiːɒn/, also spelled eon (in American English), originally meant "life", "vital force" or "being", "generation" or "a period of time", though it tended to be translated as "age" in the sense of "ages", "forever", "timeless" or "for eternity". It is a Latin transliteration from the koine Greek word ὁ αἰών (ho aion), from the archaic αἰϝών (aiwon). In Homer it typically refers to life or lifespan. Its latest meaning is more or less similar to the Sanskrit word kalpa and Hebrew word olam. A cognate Latin word aevum or aeuum (cf. αἰϝών) for "age" is present in words such as longevity and mediaeval.[1]
Although the term aeon may be used in reference to a period of a billion years (especially in geology, cosmology and astronomy), its more common usage is for any long, indefinite period. Aeon can also refer to the four aeons on the geologic time scale that make up the Earth's history, the Hadean, Archean, Proterozoic, and the current aeon, Phanerozoic.
