big bang?
so athe universe every now and then contracts into one ball and expands again,
but i have a problem
i cant see there that there is an end too the universe , because what is at the end, nothing, no such thing so it must go on and on, neverending, so how can all this contract into one ball, it does not make sense
so the universe just appeared out of nothing, again theres no such thing, the universe has just simply been here all along, and has always been here so is the big bang a local phernomena to our part of the universe

Simply stated... thre's no evidence that the universe will contract "into one ball and expands again"... That, at one time, seemed to be the explanation, but confirmed discoveries within the last 25 years indicates the universe appeared ex nihilo, and within as unimaginably short period of time (10^-43 seconds) expanded exponentially to nearly half the size measured today. It continues to expand and the expansion rate is increasing... So, making sense is not required, but the universe hasn't "always been here"...
or this maybe:

When scientists talk about "the universe" they really mean the known universe (the visible universe) which has a start time. Positivists would argue that discussion of events before the big bang, or events possibly occurring outside of the known universe are not questions for science. Despite Clanad's gallant attempts to bring a creation event into the big bang model, it is not known what happened in the brief period after the big bang SINGULARITY when general relativity breaks down. Saying that scientists think it was a creation event is misleading, it is simply not known. Quantum mechanics argues that these or any other events cannot be predicted with complete accuracy and this leads the way to a Many Worlds Theory where, roughly speaking, all possible events that happen form a universe of their own, hell, i may even be successful in one of them.
. It is thought possible (by stephen hawking amongst others) that a theory of quantum gravity may provide a natural limit to measurements and make a theory of everything, explaining what happened at the beginning of our known universe, possible. However, it is likely that there will never be an ultimate theory of the universe because more accurate measurement just brings up new phenomena that needs to be explained. Despite which, a theory of everything wouldn't necessarily tell us what happened before the big bang, just what happened a fraction after it.
The Big Crunch:- Is a hypothesis of what could have happen to the known universe in the past and could happen again in the future, it has not been completely ruled out it is just one of the possibilities.
