Ohh, god, one of the many things that gives me a headache.
Theoretically, if time is considered a dimension, and the universe was created with the Big Bang (which thus meant the dimensions, which I think someone said there were 11 total- can anyone list them? I get lost after three ), then when the universe is destroyed it is logical that the dimensions (thus time) will cease to exist.
Then something else could happen. Who knows, maybe something somewhere will decide to make the space hat the universe took up a giant replica of Central Park.
See, I can't go on after the universe ending because then brings the major headaches:
If the universe is in space (and I believe it is SPACE that allegedly goes on forever, and the UNIVERSE that has an end sooner or later) then what happens if the universe ends? There's now a gap in space which will be filled by space... but what does space come from? If the Big Bang created the universe, what created space? Better yet, whatever created space, what canvas was space made on? And what canvas was that canvas made on? It just goes on and on and on (need *I* go on?)
