I don't believe specificlly in the big bang theorem.. maybe the universe expands and contracts in cycles, therefore in a billion years things are going to start attracting itself one another until it all compresses itself into a particle of infinite mass witch at some point explodes and therefore an infinite number of big bangs over our existence.

Or, another plausible explanation is that there was no big bang.

All I know is, whatever the explanation is, it didnt have a beginning. universe always existed in some form or another.

matter has no beginning and no end.. it's just transforming itself
