If the multiverse exists. Would that mean there be something even bigger than that? Would this mean there will always be something bigger and no possibly ending? If there is a multiverse would that mean universes within it would be moving and colliding the same way galaxies do in them?

I know people have speculated for eons about the possibility of a multiverse but what could lie beyond a multiverse? A multiverse that is comprised of more multiverses? If that is the case then would a galaxy be considered a miniverse?

Also, what is “the cold spot?”
