does the big bang theory lead to infinity?

Question

i know the big bang is a theory,but sounds quite plausable,if so expansion of the universe and then contraction,if this happens continuously would it be defined as infinity?

Answer 1

There are two main ways scientists come at this.

A: There is a limited ammount of dark matter (not proven to even exist) and once the universe expands to a certian point, it'll snap back like a rubber band. This is called the 'Big Crunch' and as I recall is slightly prefered because the universes expansion seems to be slowing down. I might be wrong about that last part.

Logicaly, this would appear to be cyclical. What could create a sub-atomic mass of that kind of density except the colapse of a universe? But we don't know.

B: There is no such thing or there is an infinite ammount of Dark Matter and the universe will continue expanding indeffinetly. Entropy continues forever until there are no stars, no galaxys, no nebuli. Just matter floating around in tempatures approching Absolute Zero. This is called the 'Big Freeze'. I prefer this one myself.

The Universe is a great and special place, why cheapen it with reruns?

Answer 2

No, it doesn't. If Big Bang theory is correct, then the universe began at a certain point in time and is continually expanding. Therefore it can never be infinite - since there are always going to be moments when it is bigger than it was before.

Also, if Big Bang is followed at some point by Big Crunch, then again, the universe can't be regarded as infinite, no matter how massive. I suppose it could continue to expand and contact an infinite number of times - but that wouldn't mean that the universe itself was infinite.

For example, I could sit here till judgement day continually blowing up and then deflating a balloon - I could do that an infinite number of times, but it wouldn't mean that the balloon itself was infinite in size.

Answer 3

What part of gives the impression of infinity? In that it has a beginning - believed to be about 13.7 billion years ago you cant really call it infinite in time - if the universe collapsed to a point in the future possibly to rebound in a new universe you might be able to call this cyclical pattern infinite in that it could in theory have been going on forever. This is the ekpyrotic scenario which is derived from string theory. Current observations though suggest our universe is accelerating in the expansion which means it could never collapse back to a point. It may be never ending in terms of the future but it will be a dull dark future indeed. You could also investigate the big rip and big crunch theories.

Answer 4

I'm going to answer this question in a different sort of way. YES, the big bang theory does lead to infinity, and here's how. Scientists don't really understand the universe at its earliest moments because of the conflict between General Relativity and Quantum Mechanics. When married, these theories lead to one answer: infinity.

Answer 5

Yes, the Big Bang Theory of the Universe leads to infinity.

Answer 6

The big bang theory is outdated.
Scientists now believe that the universe originated from a half eaten Enchilada that had been left unnatended at the back of Jack Shuttlebottoms fridge.
With Infinity produced from C.K.

Answer 7

I think that the latest scientific thought is that the universe will not stop expanding; there isn't enough matter in the universe to result in enough gravity to bring everything back together. Some of the latest ideas (thoughts) by scientists, which I've read of, involve multi-universes, our universe being one of them, contained within a super ever inflating mega-universe. Some of these ideas and theorys are quite strange, but very interesting. There are many books written in laymen terms that better explain these theories. They are not too hard to understand, and you might find them interesting. In a library or book store look under the heading 'cosmology' find a book written in understandable terms; not a whole lot of math and complicated explanations.

Answer 8

Only time will tell.
Were not sure if it will yet.
But if it does will we be able to call that by definition infinity?
I guess not because its just one Universe in an infinite state.
That's still happening inside something, sorry I know thats an over simplification, but you see what I mean. Until we know if it will contract again its just a paradigm.

Thats a mad question though, an you got me seriously pondering now.

Time in Space an the relavence to the question of infinity,

I was'nt really going to sleep anyway.... lol

Answer 9

You need an update to that theory. First, the universe is accellerating in its expansion. That means it'll NEVER collapse, so it can't rebound. It'll only grow cold and dark as the ages pass.

Second, even if it DID rebound, there would be some theoretical loss of mass/energy with each 'bounce'. So eventually, even the bounces would cease.

Answer 10

i imagine that there's a semantics problem the following. before each and every thing all and dissimilar in astrophysics believes that vast bang idea describes each and every thing from to illustrate a million 2d after the preliminary 'bang' previously virtually completely. the in problem-free words debates are what befell in that first 10e-35 of a 2d after the bang. After that aspect the evolution of the universe is somewhat nicely understood and stands as a lot as a plethora of predictions.
