What is beyond space?

Nothing! Either space goes on forever (is infinite) or it comes back around
in some kind of closed loop, but the way we understand space right now, it
is impossible for it to have any edges, and so there is no direction you
could point and say "50 yards in that direction space ends".  Since there
are not any ends, there is not really any way to understand what "beyond"
means.  But there could be other things that "exist" that are somehow
outside our own universe - parallel universes!
