Hi, I have some questions that came up while thinking of this idea of parallel universes, I'm glad if someone could help answer these.
1. Assume we somehow discover another universe, does this discovery then imply that OUR universe is finite in size? Or is it still possible to have an infinite universe?
2. I've read that one POSSIBLE way to discover other universes is the way they MAY interact on each other with gravitational forces. However, assume we have 2 universes affecting one another with their own gravitational force, these forces, do they propagate through something in between these galaxies? Maybe this question doesn't even matter, neither the answer to it. But think of it like general relativity, mass bends space-time. But does a universe as a whole also bend some kind of "space-time outside the universe", this "thing" the universes exist in. Maybe this whole idea is totally wrong since I imagine space-time to be something that exists IN our universe. This question might be very nonsense, if so I'm sorry, it's just imagination playing in my head. Maybe the concept of time is not needed "outside the universe", or in this "thing" the universes exist in. However, it's fascinating.
Thanks in advance, please keep in mind I have no knowledge at all of this theory of parallel universes.
