There is a theory that space is bent into a spherical shape, much like the Earth, so if you constantly travel in one direction, you will come all the way back around to where you started. That may sound impossible, but in the middle ages people thought it impossible that the Earth could be round, so it's not that great a leap of the imagination to think the universe is also a sphere.

Heaven :)

I think I've read somewhere that the Universe is constantly expanding, somewhere around the speed of light, so that might mean an endless journey for anyone who attempts to take it...

This is in "crazy thoughts", not astronomy so I'll keep it basic. The universe is expanding (creation) and is actually speeding up, not slowing down as was originally predicted. There won't be a big crunch as opposed to the big bang and it's expanding equally outwards in a sphere. Using C.O.B.E., the cosmic background explorer observatory, they've actually seen almost all the way to the edge of creation. Not in the traditional sense, like a visual or photographic observation, but rather the remnants of the radiation FROM creation. The edge of the universe. Nothing exists on the other side. It hasn't been made yet. No space, no matter, no time, no energy. Nothing. As for getting to it and passing through that line? We can't. Even if we had managed to start out, the day the universe was created and began to expand, we couldn't keep up, let alone pass through.
