Katze97 I have a question you might could answer.... Is it possible that if the gravitational wave from the initial bang permeated into our aeon, that would be information traveling across time without space? Given this premise, how can waves travel to our observable universe given there was no space for the wave to traverse. Also, if the wave could/would emanate from a single point, wouldn't that point be well far outside of our observable universe given the current age of our solar system.

This is a truly brilliant man. Much respect for Dr. Penrose. I am toyally onboard with what he is saying here. I don't believe there was ever a "nothing". There was and always will be something. It's ignorant also to think that the only existence is of time and space. There could be some other form of existence that we can't comprehend because it is locked away from another aeon. This idea of the dark matter he suggested is just brilliant!

Yes, it´s the paradox of creation/eternity - that the human mind can not grasp. If you can explain what started the eons, you can ask what was before and how could it come from nothing. If you assume that the eons are there forever and have always been, then the human mind wants to create a beginning again. But personally, I would rather assume that the eons are there forever and have always been, with no beginning. I think existence itself is paradox, but it´s a logical consequence of nothingness, that you have something. Or the other way round; if you have somethign, then there also has to be Nothing. Duality seems to be fundamental. A medal can not have just one side, but always has to have the opposite site in order to exist. And since I think there is nothingness (it exists, but in it´s existence it doesn´t exist per definition), which doesn´t need a "beginning", you also have to have Something, which then also has no beginning.

This model is elegant and beautiful. This idea means light knots up into mass and creates time but then temporal decay undoes the knot until big=small and hot=cold and light's time knot does not exist. But that non-existence equivalence then equates all light as one light as no light and you have another singularity "Big Bang". Bosonic string theory works well with this model since a tachyon field would be required to link all those universes together without the platform of time being there. The only issue then is determining how to get the asymetric half-integer spin fermions out of the set of symmetric bosons. It might be as simple as dividing a spin1 boson by a spin2 graviton to give you a half spin fermion but we won't know that till we smash electrons at high enough energy to see if we can get a gravitation out of them. That will happen at the CLC eventually; clic-study.web.cern.ch/

Professor Penrose has done a "bang up" job of explaining the empirical evidence from the Universal wave-package properties, in terms of standing waves, to which he has applied conventional nomenclature.., judgement of actual causes left suspended (?). I do not make comments that may be misinterpreted as criticism, so all I can add to this is that continuous creation connection is the temporal wording of CCC theory, ie both sides of the Spacetime penny, incomplete and needing new eyes and minds. My words are constantly changing to get the best approach to integration with "known physics", but everyone has to think about the mechanism of QM-TIMESPACE from their own metastable perch on the singularity navigation platform. (It's fun to imagine and headache material, simultaneously, of course)

Maybe I should add Sir Roger to this one ... The super giant temperature force crystal we call the Big Bang is still there, because temperature time-dilation ... Universe Expansion As for expansion itself, there is a temperature based 2 directional tensor on every particle we have ever observed from plasma photons, up to any atomic weight we have encountered so far. If you consider a deeper weight particle lives at an interference point and is constantly being fed expressed heat from it's immediately (doubled depth and distance) deeper particle, or from ambient temperature at its' depth in the weight space. The deepest particle interferes a new weight and goes the summed interfered temperature C^3 or degree Celsius deeper in its' weight space, the internal "Cavendish" tensors from the particle depth SR monodimensional BB space, pulls the particle back "up" the temperature scale. The particle will shed two "half temperature" photons back up the atomic pipe causing interference in the half distance position of the atomic pipe and the same thing happens at that temperature scale, all the way back to the aperture of the atom and being expressed as a zero degree Celsius photon particle (No velocity at all). If you consider the temperature over distance equation, and add in the redshift of the exhibited photons you realise that the redshift of a "stable" atom by definition on the C^3 scale has to achieve a temperature of zero degrees Celsius as it finds its' position in the "visible space". So instead of the stacked atom we observe, we actually have a redshifted temperature pipet from the Big Bang , too our visible space, which is expressing a Big Bang instantaneous explosive energy at Zero Degrees Celsius and Zero Velocity! This is our visible aperture of space, and it (the Universe) simply started growing when the expression of the BB in its' GR'd observable frame of reference (i.e. expanding at C) , a C velocity time dilated by its' temperature and redshifted by the decreasing to zero degrees aperture space allowing zero degree Celsius photons to "simply appear" in our space, expanding our Universe one photon at a time multiplied the the "Skin Depth Aperture" of our observed universe. Atomic particle formation, is the other side of the BB energy cycle through our space, which means the atoms are slowly in comparison "swallowing" photons that are too hot for the zero degree space and their journey back to the Big Bang has started. When you consider the amount of matter that we observed versus the amount of empty space, it's easy to see why we are still expanding, and likely will continue to do so forever. I have read Stephen Hawkings' paper "Properties of an Expanding Universe" and everything he postulates and describes fits in to the above theory.

I think Dr Penrose has opened up some very interesting points about cosmology. However, as we have very little understanding about why and how there are extra dimensions and the full role of time, gravity, constants and an infinite amount of variables that are encompassed throughout the passage of everything. Then it would still be a little bit early to know everything about everything. Maybe we could invent Quantum nets without anchor points or summarise any given system without boundaries and be absolutely sure it's correct every time without taking into account the unknown. But as it is the unknown doesn't exist anymore if we have fully understood the ultimate foundations of Mathematics and Physics forever. I don't think it matters at all if God played dice or not we need to be 100% sure about everything before moving onto the next big step. I put it to everyone: What is the next big step? Never ending discovery perhaps??? Hahaha ... Now this is mind blowing.

Though still kinda unclear how we get from the end of an 'aeon' when all mass has virtually disappeared, to the next 'Big Bang', when it would seem the universe, and all matter is 'expanding' again (in other words, where's the next 'matter' come from, if it's all been dissipated in the previous aeon)?

Yeah, if You find his explanation on this, hit me up! He clearly states that all the matter is turned into radiation and that dark matter decays as well. Then the photons dispersed on unimaginably huge areas of space inflated into the next big bang. Naturally, the Standard Model suggests no 'matter' existed at the beginning, so it seems that answering this problem is obsolete. In both CCC (Penrose) and the SM (mainstream) the quarks could have emerged in the same way, from energy I suppose.

Conformal geometry can work both ways, "mapping" the very large into the very small and vice-versa. A way for scale and dimension to be lost would be for some arbitrary region of a larger universe to be sufficiently isolated, or to reach a particular initial condition in the universe at large equivalent to such isolation. Exponential expansion could produce that for the universe at large but also for any number of small regions. Once you have that isolation "small" loses its meaning, and a "cold void" might be regarded as infinitely hot and energetic. See, I'd like for CCC to give us not just one cyclic universe, but an unbounded number. If that's the case then the hawking points are either statistical flukes or evidence of some other phenomenon, like collisions of bubble universes embarking on their own course of cyclic life.

Hey Rick, you sound like someone who might entertain a curiosity I have, which is inspired by Penrose's CCC proposal. Penrose puts the aeons in succession, so the start of the third aeon would be a whole aeon away from the end of the first, like segments on a bamboo. (I'm numbering them just for illustration.) My provocation is that it's not like a bamboo, but like a higher dimensional toroid: the end of an aeon loops back to the beginning. It seems self sustaining and elegant, and I wonder if it could be as mathematically valid as Penrose's bamboo version. I've spent time wondering about the relationship between successive iterations, and a sort of "thickening" or "deepening" of reality along the resulting degree of freedom, which is a sort of hypertime.

It's a provocative hypothesis, but it's long way from being proven. In other lectures on the internet, Penrose himself admits that. It's a beautiful idea, but as the saying goes, many beautiful ideas are shot down by ugly facts.

I mean if we are debating whether DNA or the recent discovery of the intricacies in the flagellum of a bacterium or the fine-tuned constants is intelligent design or not today then obviously the next generation who will see black holes arranged in a specific way will do the same as it is less complex than a nano-sized rotary system.

No, but Sean Carroll and Leonard Susskind are on the record hinting at something like that. In their case it has to do with the event horizon created at the place which is exactly far enough away (edge of the observable universe) that cosmic expansion is moving away from us at the speed of light. That creates a boundary mathematically like a black hole horizon, except we are on the inside. With potentially some similar consequences. For example, I believe Carroll once said during a Q&A that due to ER=EPR and current ideas about Hawking radiation, in some sense that boundary may act as a sort of entanglement mirror, where multiple versions of the universe are held in superposition inside it. I suppose a mechanism in support of the Many Worlds interpretation.

Penrose is a mathematician, and a very good one at that. He didn't just come up with crazy ideas, he did the math and the math tells the story. If there is one thing we have learned in scientific history it is that one should trust the math (unless there are evident errors in the math itself). The math he is using is conformal geometry, and there infinity does indeed have a finite boundary.

I like to think that the aeons loop back on one another, so they aren't in series but connect like a multidimensional toroid; a snake eating its tail. Then each aeon is the same as the next, and there is no first. Though maybe there is evolution - or variety - between the iterations, and one could speak of a starting point, somewhat like the center of a spiral. (I.e. it took many iterations to get to the current complexity, even though all the iterations coexist. Metaphor of a Russian doll.) Anyway, just musing. I find the elegance appealing.

It's a rescaling. The idea is that nature does not care about absolute numerical values. The problem is that if nature does not care about absolute numerical values, at all, then there is no reason for anything to happen at _some_ value. That's the problem with all of these models: they are currently still too abstract to predict why things are happening, at all, in the universe. Penrose is ill-equipped to answer that question. He is a relativist, i.e. he knows next to nothing about concrete properties of matter and radiation. General relativity reduces all those details to a trivial stress-energy tensor in which all details are lost. In reality, however, it's the detailed properties of matter that drive the evolution of the universe at the early/late stages.

I think in a sense its a fractal dimension. The previous is a singularity and the next is infinitely bigger. Entirely new matter and the relativity of spacetime size (irrelevant to photons perspective). And by new matter does he mean a kind of new form of it or just a scaling up i dont know. (Presume if it follows the same rules, and is fractally similar then its the same, or at least mostly the same with a little twist) What he has explained is not a crunch or collapse.

If the universe, in a state without scale (as a result of having no clocks, again a result of having no mass, ie. being comprised entirely of photons), the conformal principle theoretically allows scaling back to a singularity. But I agree, have been trying to find an answer to the same question. What causes the scaling. What if the fabric of the universe is always the same, across aeons, but it’s the energy density that undergoes through the phases? (what I’m after here is a follow up to RPs statement of not finding inflation a part of his scheme).

How does space fit into this model? Is it ever expanding irrespective of the aeons, or does it collapse before every new big bang?

Listening to Sir Roger Penrose explains his view, a question comes to my mind, that is, "Is photon eternal?" I ask this question because it is obvious to me that, in order for his view to work, photon then must be (or he must assume it to be) an eternal entity, otherwise his view will not work. Am I correct here in seeing it that way?

Ultimately nature is what nature is, whether we think it's the most 'common sense' explanation or not. The question is not whether or not part of (or all of) the current inflationary big bang model is wrong (elements of it most probably are at the least), but what to replace it with. If Penrose's model turns out to offer a seemingly identical explanation, there is no scientific way to determine which is the 'correct' model (however Occam's Razor suggests we should prefer the most falsifiable model). If however, when examined in great detail, one model offers a prediction that is different to the other, and that difference can be observed/tested, then it is possible to eliminate one of the models.

I think you are gravely mistaken if you assume that Roger Penrose does not feel an obligation to scientific correctness. I think you have it exactly upside down and Penrose takes this obligation more serious than most other scientists do. And that is why he started to think out of the box. He noticed that conventional models aren't scientifically correct, so he tried to come up with one that is.

2:46 "It's not really energy". Yes it is, Mr Penrose. But as you said, and rightly so, it's "a strange kind of energy." This "strange kind of energy" is called 'Actus Purus' (pure actuality, or pure act, or pure energy, or actuality unmixed with potentiality) This 'Actus Purus' is what classical Christianity - courtesy of medieval scholars such as St. Thomas Aquinas - call "God". Time doesn't affect photons in our universe because our universe was designed with the exact amount of [rationed] energy to make the speed of light (C)= 3x10^8m/s in our universe. If there's another universe with more energy, the speed of light could be for example (C)= 5x10^6 m/s or (C)= 2x10^3 m/s if less energy is rationed to that universe. Whatever amount of energy "Pure Energy" decides to ration to a new universe determines the speed of light (C) of that universe. 😎 Most atheist scientists seem to find it difficult separating energy from matter. Their predicament is understandable - it's also difficult to separate mind and body - because all we know about energy in our universe is through matter. Energy activates matter; it gives matter life, so to speak. This is why learning philosophy is key to a better understanding of the sciences. As a great philosopher once said, "Philosophy is the art of making distinctions." "For the scientist who has lived by his faith in the power of reason, the story ends like a bad dream. He has scaled the mountain of ignorance; he is about to conquer the highest peak; as he pulls himself over the final rock, he is greeted by a band of theologians who have been sitting there for centuries." 😂 - Robert Jastrow, NASA Astrophysicist (God And The Astronomers)

Interesting theory, and I've heard him talk about it before, but he's wrong about inflationary theory (3:12). Inflationary theory does not posit that inflation occurred after the big bang; quite the contrary really. Inflationary theory posits that inflation actually "caused" the big bang, in a very real sense (assuming it's proven to be true, which we can't assume until we have verifiable evidence). The inflaton field "fell over the cliff," as it were, creating a massive conversion of potential energy into matter and expanding space, and it is that which we perceive to be our big bang. So it wasn't "big bang and then inflation," but instead the other way around. Alan Guth used to say that the big bang never says what banged or how it banged; inflation fills that gap, and Roger is simply misguided when he says that inflationary theory says otherwise.
