meganmaySat, Jul 14, 2007 on the first day of an astronomy class i took a while ago, the professor was trying to explain that the outter space was infinite, and just as he was saying, "it's very hard for many people to wrap their head around this" a girl raised her hand and asked, "but where does it end?"
i just realized that i only just realized what that means. the dictionary says the universe is believed to be 10 billion light years in diameter and expanding outwards. but what is it expanding into? where did that space come from? can we safely say that this space is devoid of matter and therefore infinite? is the one we know the only big bang that ever happened?
