I've always been the type of person who thinks about random things to a great extent. But one topic in particular is the universe; I'm constantly thinking up questions for myself. How big is the universe? Is their an end or 'edge'? If you were to keep traveling in one direction through space, would anything change / happen? Are there life forms with similar or even completely different (as in, for example, they don't need to prey on others or even need to eat and such) ways of living? Have any of them seen us? Ever wondered where you would end up if you actually survived a trip through a wormhole? I mean, there's just so much that we don't know about. But ultimately- will we ever be able to answer our own questions? Any responses or thoughts you guys wants to share?
