I don't see WHERE scientists manage to pull this out of. I mean, what do we know about anything beyond our own solar system?Delphine wrote:The universe is expanding, so it can't be infinite. It has to be expanding into <i>something</i>. Unless it's expanding into itself.
For example, Stephen Hawking's theory that the expanding universe was related to time what absolutely absurd. He said when the universe started collapsing time would go backwards... because as time goes on the universe gets bigger, so obviously if the universe gets smaller time will go backwards. Uh, sure, okay.
Anyways, Zeta's explanation makes the most sense.
