Do Universes Expand Because There's Nothing to Stop Them?

[sherlock ohms]

would it be fair to say that Universes(??) on all scales, which consist of 'something', expand for the very simple reason that there is, quite literally, 'nothing' to prevent them from doing so?

.The existence of multiple universes is not a proven fact. The only universe we can speak about based on observation is this one. This one appears to be expanding. However, there is no reason why we should assume that all other universes, if they do exist. must follow the same pattern. Especially if those universes function under laws completely contrary to ours.

Of course this universe expands because gravity has proven as yet insufficient to halt or reverse the expansion. So in that sense you are right. It expands because no insufficient counterforce to the expansion has been applied. However it also expands because of the newly-discovered dark energy which accelerates its expansion making the stoppage and reversal of the expansion seemingly impossible based on our current observation of the detectable universe. Which of course has to be applied only to the detectable since beyond that we don't really know what's going on.
