What people forget is that initially when Hubble observed and formulated his BBT the reason why he said the redshift distance relationship was due to expansion, rather than the more obvious light loses energy over distance...was because Relativity theory and the photon model made predictions that were not consistent with the observed redshift of light over distance. Technically when cosmological redshift was measured the correct scientific method would have been to discard einsteins photon and relativity theories. Seeing as they predicted ...NO REDSHIFT of light from distant galaxies.

They simply *assumed* that some vague woolly thing had a beginning, and the first mark of sloppy thinking is not to challenge or examine hidden premises and assumptions, but maybeThe occupation of playing games with numbers does not require a degree of rigorous academic analysis.

Men (human beings) use words and simply assume that there is some substance behind what is no more than the veil of words, and if you try to go behind the veil of words or define is dreams - that being the nature of the associative apparatus or dreaming machine. men (human beings) simply*assume*that because they have the word they necessarily have the meaning of that word, because words act rather like veils they prevent the experiencer from actually being able to discern what is underall behind the veil.

Now do you understand why it is that men find it so difficult to do a detailed and careful examination of their associative apparatus or dreaming machine? - And why that is?

A fascinating discourse! A remarkable mind expressing abstract mathematical modelling of the universe -- explaining in plain and vibrant English how the remote future (of the accelerating universe) could be analogous to the early beginning (of the "Big Bang" universe) while noting that in either case no measures of time is left (for, no mass but only radiation is available). The mathematical idea of conformal mapping and Escher's "angels and devils' at the boundary of this painting, are noted as analogous to the boundary at the meeting point of both the ending and the new beginning of the universe (not cyclic). Penrose does not hesitate to point out what is purely mathematical, what is possibly physical, and how his model is falsifiable and, so , also how it may be tested by cosmological data in the coming.

It never "began", it was always there! 👍

not in this lifetime, lol. All we know with absolute certainty is that we exist to some extent. Everything else is really hard to prove definitively and objectively, even if it's easy to know from a subjective view. And my subjective view is that the universe has certain laws which govern how it works in any given state; our current state has the 4 fundamental forces (gravity, strong force, weak force, electromagnetism), 3 clear spatial dimensions, and spacetime, but the early universe had fewer forces due to the state it was in, so it's not unreasonable for the early universe to have had various other laws that may seem illogical to us now cuz the state it was once in is hard to reproduce for studying, including how time works. I don't think the future of the universe will be boring as this guy stated. Consider the universe expands at an accelerating rate but is currently offset by gravity and the other fundamental forces which keep things together; what happens when the acceleration is so powerful that the fundamental forces fail to hold things together? Atoms torn apart as the space between the nucleus and electrons expand and separate them; the inside of particles break apart into quarks which will somehow interact on their own; heck, the speed of expansion could become so fast that spacetime itself has a hard time managing to stay together. Who knows what happens then. Even simple stuff like black holes have unknown deaths (they radiate and eventually disappear, but what's left behind? Black holes supposedly tear a hole in spacetime itself, so what happens to that tear? Does it stay? Where does it go? Do these tears repair? What's left behind after black holes evaporate to a point where the remaining density is less than what's needed for gravity to trap light?). So many interesting things, and I love/hate it. Love the interesting properties, hate the lack of answers.

It’s oscillation over measurements of “time” most struggle to comprehend.

That wave function collapses as soon as consciousness decides what a given thing “is” during that snapshot of space and time. This also addresses the fine tuning debate. That’s my theory.

That magnetism will lead to larger pieces of “matter” which will intern lead to new gravitational mass, all hurling towards a new center, over those eons I’m sure there will be new life and new consciousnesses. Then that universe will collapse on itself, and bang, all that matter starts to disperse to a new entropic absolute zero, and repeat. It’s all in oscillation.

Have a nice day

I really appreciate people that approach this question from the multi-position that this person does. I'm just a humble guy with two humble degrees and astrophysics and historical geology. Just undergraduate degrees so I'm really not that smart. I am also an ordained pastor. I know those two things don't usually mix together but they actually do.

I had a misspent youth and am now regretting it. At a time when the Cold War could have hotted up at any moment, booze and birds seemed far more important than education. But I'm delighted now that I understood at least some of this, and am going to watch it over and over and over until that 'some' becomes 'most'.

Basically, the idea is the universe uses mass to keep track of length and time. There is also a mathematical tool called a conformal map that basically tells you that regardless of the size of something (however small or large is it), as long as it's the same shape, the objects are equivalent. So using this conformal map you could equate say a very large sphere with a very small one, you couldn't tell the difference between the two with this mathematical tool applied because it disregards scale and focuses on the shape of something (which is why he said the angles are the important part, those are preserved). If we assume that all mass in the universe will eradiate away into massless radiation (this assumes black holes due evaporate into Hawking radiation and that proton decay is real), then we have a unverse that is, despite its much larger size now due to inflation, conformally equivalent to the big bang state because there is no mass in either state, only uniformally dispersed radiation that is in thermal equilibrium. Why do these things equate? Because both have the same _shape_ despite one being muuuch larger in scale since the energy is uniformly dispersed that gives the same spacetime topology and there is no longer any mass to make distortions in that spacetime which is how the universe 'keeps track' of its size and time. Keep in mind they are equivalent only in a mathematical sense because we applied this mathematical conformal map tool to a end-universe state and that map equates it to a big bang state, so the meaning of the maths would be that the big bang is the same as the end of the previous universe. Now obviously this is just a neat math model built upon assumptions, but one which is testable to a degree since the radiation would encode the gravitational waves of the previous universe since it affects radiation by being 'wiggles' in spacetime. It's a bit hard to wrap around without getting into the maths, but as far as the maths goes it seems plausible.

@@ThatCrazyKid0007 Thank you very much for your effort. I have four questions though. Is this similar to the big bounce model? How is the radiation encoding gravitational waves of the previous universe? And what does "encode" mean? And lastly, would it make sense or is it possible to understand this process as infinite in time (especially in the past)? I hope it's not rude to abuse you as a source of information.

@@biedl86 Hahaha all good mate, happy to answer as much as I can although a disclaimer I am only a layman that watches a lot of physics content online. 1. The principles are different so they are not the same. The big bounce says that eventually gravity will win over inflation and become the dominant effect in the universe, thus pulling together all of the mass back into a single tight region after a long enough period which would look like the big bang state again as you'd get a small region of spacetime with uniform radiation (all that mass would break down into radiation at such an intense gravity). The problem with this model is that assumes inflation would kick start back again and expand the universe back into the expanded one we know today, thus the name big bounce, before the gravity collapses the whole universe into a black hole. They too claim there is a way to test this possibility using the CMB but I am not sure how exactly it would be done, probably checking if the radiation encoded any gravitational waves from the previous bounce. 2. & 3. I assume the encoding means that since the universe is filled with gravitational waves caused by black hole collisions and since gravitational waves 'stretch' light (which is basically what radiation just is, a bunch of photons), as in they cause the light's wavelength to increase lowering its energy, you could in principle analyse the CMB and find patterns which could only be caused by gravitational waves, like say the wavelength of the light changes across a region of spacetime in a wave-like pattern that looks a lot like gravitational waves stretching light. This would be evidence for a previous universe, or at least some kind of pre-big bang state, because we shouldn't expect to see any gravitational waves in the beginning of the universe since it was all massless uniform radiation. Thus the gravitational waves from before the big bang would be encoded into the CMB of the current universe. 4. That's a bit tricky to answer since our conventional notion of time breaks down in these scenarios. Since if you remove all clocks from the universe (and remember, mass is the universe's clock), you cannot descern the past from the future, it is all a single temporal state. I guess it could be interpreted as an infinite causal loop, you'd just have no way to rewind the clock to before the big bang and into the previous universe to retrieve data, you'd hit a temporal discontinuity since you don't know to what scale the previous universe was conformally mapped to. So from our point of view, there is no infinite past, but from an observer 'outside' the universe they'd observe an infinite chain of universes. If you want to learn more about this model, it is called Conformal Cyclic Cosmology. PBS Space Time did a video on it explaining it a bit more into detail in their 'What Happens After The Universe Ends' video.

For anyone interested in learning more, this is called Conformal Cyclical Cosmology

Another way to think about this is “the equivalence” of a circumference or a straight line, provided you zoom in or out sufficiently

Big bangs before big bangs, it's infinities in all directions!

The mark of a true genius is someone who can use simple language to explain complex ideas.

Mind blowing. This has changed my whole view on what the universe is, and what it’s doing. Question from me; is this behaviour somehow observable in nature elsewhere? When the Universe has no more mass and forgets it’s size and repeats itself.. what else does that?

What helps is a change of perspective, in realizing we ask the wrong questions some times, or fail to be aware of how things truly are. In this case, there IS a simple example, as long a your change your perspective. It starts with the question: what is the opposite of death? Our mind tells us that the answer is life. As does dogmatic science. But there in lies the problem. The right answer for the mind, the limited, is the wrong answer for the infinite, which I personally call the heart. The correct answer is that the opposite of death is birth. Life itself is eternal. Life is existence. Life isn’t just organic material, but all that is. There is nothing before life, and nothing after life. Trying to ask what came before life is like asking what came before existence or how can we make a square circle or what does the color purple smell like. Even nothingness is in a sense ‘something’. Space is another word for it. Einstein knew this. Recent confirmed evidence by LIGO of gravitational waves finally proved it. That the empty vacuum of space is an illusion but rather this curved space time for which we reside yet are a part of all at the same time in this moment. In this awareness, then we can comprehend a binary universe in flux from nothing into something. A practical example of this are black holes (which I prefer to call fuzz balls based upon recent discoveries) as they beautifully represent the universe on a microcosm as something that is stuck in the state of becoming and not becoming, of being yet not being. My 2 cents
