Do you think our universe, at some point in time, will come to an end?

@SW-User end is in nothing exists anymore.

@xRedx define "nothing".

Nothing of what? Of matter? Of time? Of space? What?

@SW-User nothing of everything. Total. Space, matter, time, stars, essentially everything is in this universe.

@xRedx in that case my answer is no.

Big Rip is coming, but who knows what does it mean? We can observe our universe only in 4 dimensions (3 space 1 time), while superstring theory says that there must have at least 10 or even 26 spacetime dimensions. As a shadow is a 2 dimensional projection of a 3 dimensional body, who knows what "shadow" would remain in the other dimensions when our 3+1 dimension comes to an end? :)

It's a good scientific and philosophic question, yeah. :)

@SW-User That's true. There is actaully evidence of this already. It's a shadow, a void if you will in a massive field of energy, indicating that's where another universe collided with ours.
