On Logic and Alternate Universes

[Neo-Scholastic]

If in the sum total of all possible universes at least one unintelligible universe exists then by necessity are other universes are also unintelligible. No matter how many alternate universes exist in a greater multiverse there will always only be one reality - all that is, was or ever will be. Now, suppose in another universe, of which we have no knowledge, the LOI does not hold. Since both our universe and the absurd alternate universe are in the same reality that means the reality within which we find ourselves is absurd. With respect to reality the LOI (and other logical and mathematical principles) must fail as a whole or not at all.

Could it be possible for two universes to not be metaphysically connected? That they are so far apart that no real causal connection exists between them. Otherwise what would it mean for there to be "multiple" universes? Isn't it still just one, bigger universe then?

I would say no; there cannot be two versions of the set that includes everything that is, was, or ever could be. In a sense the word Multiverse is deceptive since it encompasses the prior concept of universe as everything. The Cosmos. The All. Multiverse is just a modern way of conceptualizing a larger universe that has within in many local pockets of possibly alternative forces and physical constants - all subject to overarching absolute rules. So instead of Multiverse I chose the term reality since that seems to best convey all inclusiveness.
