Space is vast, but I feel there is a good possibility that it isn't just some infinite sprawl. A few things are currently accepted as possibilities...we will expand and eventually contract resulting in another big bang (essentially starting things over), we will expand forever, resulting in increased disorder, or perhaps we will keep expanding and everything will "come around" and converge again to create the big bang. Maybe that's all a bunch of crap, but here's how I think of it: matter in the universe had to come from somewhere. Let's go with the big bang theory. Everything got packed together in such a dense and tiny space that it exploded and created the universe. Where did all those molecules come from in the first place? Another big bang? I think that's the most likely situation.
