This entire business started by you asking what would happen at T=0 if the universe started running backwards and obviously, regardless of if space is finite or infinite, space would have to expand infinitely fast because at T=0 it would have a zero amount of time to expand from nothing to something.

The term comes from an expected step change where technology starts to
advance hyperbolically rather than exponentially like it has been
doing since Ogg smashed rocks together. Hyperbolic growth reaches
infinity in a finite amount of time.

I figured that since the universe is expanding, we could run to clock backward and imagine enclosing it in a sphere,If you're assuming that at T=0 the ENTIRE universe could be contained in a sphere of finite size then you're assuming that space is finite, the very thing you're trying to prove.
> say, establishing that it is finite, hence NOT flat, since flat implies infinite in spatial extent.Not necessarily. In the "3-torus model" space is flat, and space is finite, and space has no boundary, BUT it also has no edges;
a 2-D analogy of this would be a video game where if you go too far to the extreme right you disappear and then instantly reappear on the extreme left. However nobody knows what the large scale topology of the universe is, not even you.Before the discovery of Dark Energy and the acceleration of the universe,
people thought if you knew the large scale topology of the universe then you could figure out if it was infinite or finite; if it was flat then it was infinite, if it was positively curved then it was finite, and if it was negatively curved then it was infinite. But now things are not that simple and there is not a clear cut relationship between shape and the finite versus infinite question. Even a positively curved universe could be open and expand forever if the universe is accelerating. And flat doesn't necessarily mean infinite.
> we can prove the universe is NOT flat using a purely logical argument. No need to do any measurements.That's what the ancient Greeks thought, experiments are unnecessary, and that attitude is why physics didn't advance one inch in over 1500 years. I don't care how beautiful a philosophical argument is, if measurement says an idea is wrong then it's wrong.
> I sent this analysis to a professor emeritus whose main interest is in cosmology who is associated with Case Western University. He replied that my analysis dealt only with the observable universe and that the universe could be infinite in spatial extent, presumably when one considers the unobservable part.And that is why, as I said before, when Alan Guth wrote that long ago the universe was just the size of a proton he meant the OBSERVABLE universe.
> I then realized that the unobservable part was very likely caused by Inflation, and therefore the entire universe would remain finite provided we ran the clock backward, prior to Inflation.And as I said before, IF the universe was finite before inflation then it was finite after it, and IF the universe was infinite before inflation it was infinite after inflation.
So inflation is irrelevant in a finite versus infinite discussion,
as should've been obvious to you because during inflation although the universe grew by an astronomically large amount that amount was FINITE.
> the concept of a created universe, one which comes into being, which is infinite in spatial extent, assumes a type of singularity which I believe is non-physical and can't be realized;1)A belief is not a proof.
2) Apparently you believe a nothing to something singularity, where things change INFINITELY (not just astronomically) fast is possible, so why is infinite space so unbelievable?
3) Modern physics says a singularity occurred at T =0, but NOBODY believes that is the last word on the subject! Everybody believes we're missing something, but nobody knows what.> So, the professor apparently doesn't realize that his critique of my original analysis implies that his claim that the universe might be infinite in spatial extent, contains an implicit denial it had a beginning, called the Big Bang.Alan, did it ever occur to you that a physics professor at Case Western University who spent his life studying this subject MIGHT know more about it than you do?
> I haven't written him again to relieve him of his apparent misconception, though I might.Crackpots always believe they know more about a subject than the experts do, and to be fair sometimes they actually do and calling them a crackpot is a libel, but for every Galileo there are 6.02*10^23 crackpots.

Do you really wanna die on that hill?> Apparently, you love spooky action at a distance.I love any idea that fits the observational facts, and I don't care if it's spooky or not.
> Dark Energy, like Inflation, hasn't been "discovered".Inflation is a theory that may or may not be true, Dark Energy is an observational fact. Astronomers discovered in 1997 that the universe is accelerating, and energy is required for something to accelerate, we had to find a name for whatever is causing that acceleration; "unknown energy" would've probably been a better name but for some reason "dark energy" is the name that was picked and we're stuck with that.> I would conjecture that GR might be able to establish that gravity can be repulsive and attractive, and their respective influence over time might change.Every physicist who read the astronomer's paper showing that the universe is accelerating started thinking about changing General Relativity to explain it, but nobody can make it work.

It would be the greatest breakthrough in physics since Einstein, but it's easier said than done.> Because the universe is huge, our measurements can't distinguish flat from slightly curved.Nobody will ever prove that the universe is absolutely flat because there is always some measurement error, but the Planck satellite discovered that the cosmological scale curvature of space is 0.0007 ± 0.0019, and that is consistent with zero, AKA perfect flatness. If the universe is curved but it's too small for the Planck satellite to observe then it would have to be at least 9.3 TRILLION light years in diameter. Please understand that is just the lower bound, the upper bound is an infinite number of light years.

And inflation has absolutely positively nothing to do with it.> Do you believe Euclid's 5th postulate?Of course not! It is not true in general, only in the very special case of a perfectly flat space. If the fifth postulate was correct then General Relativity would be nonsense.

If the fifth postulate was correct then General Relativity would be nonsense.Stop wasting my time with your stupid sophistry. Euclid's 5th postulate is something totally believable but unprovable -- many famous mathematicians tried to prove it from the other four postulates and failed. And BTW, every semi-educated asshole knows it applies solely to plane geometry, so stop your BS. My obvious point was that there are many things we believe as true, but can't prove.

It's truly spooky and tends to support Bohr's claim that measurement causes the properties being measured;Except that Bohr's Copenhagen interpretation couldn't explain exactly, or even approximately, what a "measurement" is,
Many Worlds can do that simply by replacing "measurement" with "entanglement". If Bohr performs the two slit experiment and his experimental equipment records which slit the electrons went through, then the equipment becomes entangled with the electrons,
and if Bohr looks at those Instruments he becomes entangled with the experimental equipment, and thus he detects no interference pattern. But if the equipment doesn't record which-way information then Bohr will see an interference pattern. A measurement by an intelligent entity can cause entanglement, but so can an infinite number of other things.>> If the entire universe became infinite at the same instant the transformation from nothingness to somethingness occurred then the universe wouldn't need to expand at all to remain infinite.> You're positing an instantaneous transition from Nothing to Infinite Something.Even an instantaneous transition from nothing to finite something at T=0 already involves infinity,
and if you add one infinity to another infinity you still end up with the same infinity.

Glad you cleared that up.
> Next time you see a cockroach make a measurement, be sure to inform the List. AGOK so a cockroach isn't smart enough to collapse the wave function, what about a frog, or a dog, or a chimpanzee? When a photographic film records an image is that enough of an "action" to collapse the wave function or does a conscious being need to look at the picture? If you open Schrodinger's box and observe the cat you collapse the animal's wavefunction, but if I am in the next room and not looking at you then your wave function has not collapsed, so has the cat's wave function collapsed or not? And when nobody is observing (a.k.a. measuring) the Moon does it still exist? Copenhagen has no answers to any of these questions and apparently you don't either.
>> I can observe the observable universe by definition, and if I can observe something then it must be finite.> Sure, what you can observe, can't be infinite. But there's no guarantee that observations necessarily implyt what's being observed isn't part of something infinite. AGI agree completely, there's no guarantee that "what's being observed isn't part of something infinite" but.... you were claiming that the entire universe, observable plus unobservable, must be finite.
Have you changed your mind and come over to my position that we just don't have enough information to determine if the universe is finite or infinite?
> Obviously, one can't observe infinity. Neither can one know whether what is being observed is part of something infinite. AGWell I guess you have changed your mind. Good for you!
>> Do you believe the observable universe is the only part of the universe that exists?> No. I don't see why you bring this up.I keep bringing this up because you don't seem to understand the implications.
> There's likely a huge unobservable part, but I think it's finite,OK let's see where that leads. Obviously if the universe is infinite then it can't have a center, BUT it can if it's finite.
And we know that our best observations made by the Planck Satellite are consistent with space being absolutely flat,
and if it does have zero curvature and it's finite then the Pope was right and Galileo was wrong, Earth really is the center of the universe;
and if you travel 13.8 billion light years you'd reach a wall that was impenetrable because there was nothing on the other side, in fact the wall didn't even have another side.
>> As I said before, even if inflation never happened there would still be galaxies expanding away from us faster than the speed of light,> That doesn't necessarily imply an infinite universe.I never said or implied that it did. If I was a bookie I'd give you 100 to 1 odds that the Big Bang happened, but on the infinite versus finite question I couldn't do better than 50-50. I don't pretend to know the answer.> Sometime, hopefully, you will deal with my main point; my claim that IF the universe is infinite in spatial extent, there was no BB.If that is your main point then your main point is nonsense. There almost certainly was a Big Bang, but that information is of no help whatsoever in determining if the universe is finite or infinite.

True but if you can't explain measurement even approximately, and Copenhagen can't, then for them the word is just a meaningless sequence of ASCII characters.

Because as I said more than once before, it took light from the most distant galaxies in the observable universe 13.8 billion years to reach us BUT during those 13 8 billion years those galaxys have not remain stationary, instead they have been moving away from us. And during the last 6.5 billion years that expansion has been accelerating.

The galaxies you can see now, lights was emitted 13.8 billion years ago, at that time they weren't receding faster than c, but now those same galaxies are receding faster than c due to expansion alone, that's why they are at 46 billion light years now. So soon "some billions more years" they'll go out of view
Proof by Contradiction: If the universe is infinite in spatial extent, and came into being, that would be a type of singularity where it would have to instantaneously expand infinitely in spatial extent. Such a process is unphysical. Therefore, a universe infinite in spatial extent cannot come into being, and is therefore uncreated. AG
What about Santa Claus ? Is Santa Claus infinite in expansion ? Argument: He can bring presents to all the children in the world in just 1 night.
@Alan. If you don't start a theory from the correct facts of reality, you get nowhere. Sure, some approximations that you make might work in particular cases, but the more you stretch the theory the less likely is to be meaningful. Only because Newton theory worked on Earth, it didn't mean it worked on the solar system. Only because Einstein theory worked on solar system, it didn't mean it worked on the galaxy. And so on. These are all approximations. The more you go outside their domain of applicability, the less likely they are to provide answers. The only way to receive correct answers is if you start from the correct fact of reality. And that is consciousness.

AGA more direct way of understanding my claim: If you don't believe the universe can instantaneously expand to infinity, it must be finite in spatial extent, since no progressive expansion, no matter how fast, or for how long, can be infinite in spatial extent. Therefore, given the premise, the universe must be finite in spatial extent and cannot be flat. QED. AGI sent the physicist/cosmologist at Case Western a short email reminding him that if he assumes the universe (presumably, the unobservable part) is infinite in spatial extent, it always was, since there is no transition or evolution from finite to infinite, or vis-versa, he was also implicitly assuming that the universe began with an instantaneous transition to infinite in spatial extent at T=0. No reply. No thank you. As expected. AG

@Alan. That's like asking me how from the functioning of the transistor I can give you the formula for the fireball in World of Warcraft. Is impossible. The higher level world is an interaction between the free will of the consciousnesses involved. You will have to feel what those consciousnesses feel to understand why "the universe is expanding", etc.
@Alan. No. Is simply the truth. When reality is simply the sum of interacting consciousnesses, then whatever patterns might be produced will simply be produced by the free wills of consciousnesses engaging in social relations. The more primitive a consciousness is, the more predictable the pattern of its activity. The more complex a consciousness is, the less predictable its pattern. That's why there appear to be "laws of physics", because those "laws of physics" are nothing else than patterns of interactions of primitive consciousnesses (consciousnesses that you cannot even imagine). Then when you get to chemistry, biology, human society, consciousnesses become more complex and the patterns become more elusive.
@Alan. "Planets" is just an interpretation in your consciousness for social interactions between consciousnesses that you cannot even imagine. In the same way that this writing on the screen is your interpretation of there being a "Cosmin Visan" supposedly somewhere.
@Alan. I have no idea what you just said. But anyway, the point is: as long as you are not a paid scientist that do science in order to build technology, the kind of theoretical "science" that you want to do is just a waste of time. Because is not based on anything logical. Is just conceptual mumbo-jumbo: universes, infinities, atoms, galaxies. What are all these hallucinations ? The only theoretical undertaking that makes sense even if you are not a working scientist is understanding consciousness. Because only in understanding consciousness, you: 1. can have conceptual grounding by using entities that really exist, i.e. qualia, free will, etc., and 2. is important for your own understanding of who you are, and thus make your life better. Everything else is just mental masturbation.
Regarding the analogy with the old gods, the goal of any theory should be the truth. Theories are a side effect of the goal of finding the truth. Truth is what decides what a theory looks like, not the other way around. As such, words such as "throwback" is a mischaracterization of what a theory is doing. If the truth reveals to us that reality is indeed a network of interacting consciousnesses, and that this truth strips us of our powers to make predictions, this is not a "throwback", this is simply the truth. Truth is not throwback or throwforwards. Truth is simply truth. It is what it is. Nobody says that truth should be about making predictions. For predictions there are other tools that you can use, like developing empirical models that you can apply for a certain problem at hand. If you want to design a TV, you clearly don't use the ideas that you would use when designing a washing machine. For such practical problems you can use whatever models work. But truth is truth and you shouldn't impose on it your criteria of what truth should be. Sure, if you think long enough maybe you can even make predictions starting directly from truth. But that is just a bonus.
