I mean in the amount of energy it has and in its size. That which is observable is apparently only a sub-universe. It seems to be limited only by physical laws, but even those laws could be different in other sub-universes.
I doubt if the laws are different, but very likely our known laws would have to be expanded to explain the differences in phenomena.
Okay, I re-read that comment and I see where I may have misunderstood you.
These different laws are supposedly different ways of cooling from extreme conditions of energy density. My theory doesn't have anything to say about that, I brought it up because it's another theory out there that makes the observable universe (sub-universe) a smaller part of the absolute universe.
