It goes without saying that this is one of the most fascinating subjects ever. Of course we need first re-define what exactly it is that we mean when using the term universe/multiverse. a recommended read.

Fascinating. If we are indeed part of something much larger, then we must have some sense of that in order to define ourselves.

I don't think we know what our universe is, from a size point of view, so no chance of being able to appreciate something larger. Just have to pretend we are twice removed from baboons, and act like that.
