I too think the universe could well be eternal. But as I mentioned before I also believe in a big bang, as there is much evidence to support that theory. This seeming paradox can be explained through a cyclical model of the universe. Forever expanding and contracting. From Wikipedia:
Singularities are avoided because the observed consequences of "
Big Crunches" never reach zero size. In fact, should the universe begin a "big crunch" sort of process, string theory dictates that the universe could never be smaller than the size of a string, at which point it would actually begin expanding.
