A physics statement is meaningful only if it is with respect to an observer. So the many-world theory is meaningless.

Answer me the following yes/no question:
In your multi-universe theory, is it possible, at least in principle, for an observer in one universe to interact with any of the other universes?
If no, then it is equivalent to say that those other universes do not exist.
If yes, then those other universes are not “other” universes at all, but actually just other parts of the same universe.
