Nothing.

Undefined

Well, I'd assume that big bang should not happen in a timeless domain. Therefore, what is outside of the universe should have time and therefore, another expanding universe.

Not knowing is better than knowing I think. Much more fun to think about. Something that has completely different laws would be great though.

We dont know if there is any outside the universe. We can only speculate at this time. Scientifically, all we are able to determine is our own spacetime universe.

Is the state of change what qualifies any system as existing?

If somehow our own universe were to cease changing might we say it had ceased to exist?

I've had similar debates re time and whether it exists or is real. My argument has always been, even when Einstein mistakenly thought the universe was static [his motivation for the CC] time was still passing.

The correct answer to the question though is that the space/time/universe of which we are apart, is all there is....a universe that in effect can be reasonably explained as evolving from "nothing" Nothing being redefined as the quantum foam from whence the BB arose.
