This depends on the cosmological constant (dark energy). There are 3 scenarios: The big rip, the big crunch and equilibrium.
In the big rip scenario, dark energy will overpower all other forces and at some point space itself will expand so fast that the cosmic event horizon will be smaller than the smallest particle which means that nothing will be able to reach anything (even particles).
In the big crunch scenario expansion will stop at some point and it will reverse and in the end the whole universe will be concentrated in a point (just like before the big bang).
Equilibrium means that the expansion stops but does not reverse.
What do you mean by "surface tension"?
- pram 8y agoHe’s probably referring to supergravity theory.
- 01100011 8y agoNo, I am definitely not that informed on the subject :)
- 01100011 8y ago> What do you mean by "surface tension"? I was making an analogy to the behavior of fluids in our reality. Really though, what I was getting at is, do we, or can we, really know the nature of the universe to such a degree that we can rule out behaviors which may change as the universe progresses through whatever sequence of events through which it is progressing? I think you answered my question, such as it was.
- edem 8y agoWe don't yet know. Right now the consensus is that the universe will probably expand forever and will ultimately reach heat death. If the acceleration is accelerating though that means a Big Rip scenario, but it is very unlikely.
