Multi-verse Expansion
Just realized I should have posted this originally in this forum instead of the general one so here it is!

So, the Universe is accelerating in all directions, generating and bringing with it to what I assume a very large amount of energy. Hypothetically, if a Universe A were to run into or overlap/collide with a Universe B, would there be an energy collision, or dare I say it...Bang? Or would they simply absorb each other relatively peacefully like galaxies do in our Universe. In either case, you think the laws of nature would change dramatically in a newly formed Universe if both Universe A and B had different laws, respectively?

By the way it's my first post. Woot!

In order for two universes to collide we need a few things. We need a given universe to have an edge, we need more than one universe, we need to know how two universes or more would relate to each other spatially, and we need to determine the nature of the edge if there is one, to determine the effect that may happen if two universes collide. Without any of that, there is no structure to construct any meaningful idea of what would or could happen.

I understand your reasoning here but I'd also like to point out that if two Universes are to exist, would each Universe therefore have either a finite size and/or an edge? People may make the case that since the Universe may be "everything" in existence, there would be no such things as borders because anything beyond those borders would technically be something, and therefore everything in existence would not all be contained in the Universe. If another Universe is to exist outside our own, I would feel like boundaries or a set outer layer is necessary for both to exist. But if that were the case we'd have to rethink our definition of a Universe and declare each Universe if multiple ones were to exist as sub-universes part of a collected group that composes up the true Universe. Much like galaxies in the Universe, it would be more like sub-universes in the whole Universe. If this were the case it very well could be a never ending cycle of things inside larger things. Just pondering thoughts.
