Do you think that the universe is infinite in size?

Well, that ignores that the inflationary phase of expansion may have exceeded the speed of light (space can expand at whatever speed it wants too), and on top of that, oddly, wikipedia claims that the universe is actually much larger than that. One of their sources is Constraining the Topology of the Universe, which says:
Quote:
For a wide class of models, the nondetection rules out the possibility that we live in a universe with topology scale smaller than 24 Gpc.

where Gpc is billions of parsecs.

This has something to do with the fact the univere's expansion or something. For example, I would suspect that although we may be seeing light emitted 14 billion years ago, what emitted that light has since had plenty of time to get much farther away than that. Although I'm not sure if that is the correct explanation

I think space is still limited by the speed of light, if space expanded at or in excess of light speed there would be no lights, the radiation would red shift to non existence. I wouldn't trust wiki but either way that still states a finite size of the universe +- of 24Gpc's. Plus the big bang was a one time event, it only exists in the past.

OK, lets take a big step back and look at the whole picture. we just found an energy form that has temporal property's, basically you do something too it here and it affects a medium that it passed or is going to pass through on the other side of our world instantly if not at times before.

considering that this energy is susceptible to the universes and atomic magnetic fields then its boundaries would only exist in that of the total of our big bang from start to finish. it would be affected in all time zones of the existence of our universe as it passes through them. think of it as an invisible magnetic field that travels time.

then also add to this that many such energy units travel space as far as it can go in a striate line before some kind of gravity pulls it back, now with it travailing time, even so minute, its distances it can travel would be huge, so huge it seems it would leave or universe altogether, now if this is possible then there would be nothing for it to gravitate back too other then more of its own kind, given enough of this in an infinite amount of time I am sure it could grow in to quite a whole new universe all its own.

so the question would or should be, with the boundaries of our universe based on our perceived matters and energy's,
and our energy's reaching far beyond our known comprehensions, what are we going to consider our actual boundaries?
that of soled matter? or shall we include the radiations that hallo our known universe?

Y'know there are a couple of microbes in my gut at this very moment asking the same kinds of questions about what lies beyond Pete.

One of the things I wonder is if since a collapsing universe would create many black holes and then one big singularity,
and it would take such a singularity to even conceive of pulling all energy and matter back, and since this would also distort time, I keep wondering if what the big bang actually was is where it all gets pulled back and the temporal distortions do not release its energy's until it goes forward or back enough in time that there is nothing left then releases it all at once in one big bang, therefore there would be nothing exploding when the big bang went off other then the release of the energy's that got shoved back or forward through time.

You have to squint when you read it.
