The nature of the universe :

[spoohunter]

Will it end? Can we measure when this will happen?
Are there other "universes"? Do they have the same laws as ours?
Has it been around forever?

(Answers to the best of our current scientific knowledge)

Depends....
at the moment, it appears that it won't end, per se - it will just keep expanding forever and eventually the stars will all burn out and matter will be too spread out to reform new stars so it'll just be an ever expanding universe of cold, lifeless masses.

No way of knowing whether there are other Universes or not. (And it depends on what you define as a Universe.) Even if there are other Universes, if we can never observe them (in any way whatsoever) then we might as well assume they don't exist.

One theory is that if you can imagine it, it is possible and is happening somewhere, somehow. If the Universe is truly infinite, than this theory should hold water.

All I can say is that I feel like I'm diagonally parked in a parallel universe...
