Is this an absolute fact, or just your understanding of the multiverse?
I am following terminology, originally proposed by Max Tegmark
, that I understand is generally
accepted among physicists. See here
for more information.
Because I believe that universes in the multiverse exist in real 3D space, like ping pong balls.
That would be better described as multiple inflation events within a single space or spacetime.
The great cold spot in the Cosmic Microwave Background may be the aftermath of a collision with another universe, or a place where another
universe grew out of ours.
It could be a great many things, including a data artefact. If it is the aftermath of a collision, however, this would have taken place in a
multidimensional (eleven or more dimensions) brane space, not in ordinary 4D space-time. It's what you might call a string-driven thing.
So I wouldn't be as categorical as you when defining what the multiverse is. We're dealing with pure hypotheses.
I was trying to make clear a counter-intuitive physical idea to someone who appeared to be struggling to visualise it. I believe my post achieved its
aim – though now you've probably gone and confused everybody all over again.
