It appears that you are supportive of multiple universes and, perhaps, even a parallel universe. This relates to my question above. If you do promote the idea of multiple universes, then I return your question: "... I really don’t see any advantage of such a concept or any phenomena that it may explain ...". My gut feel is that a ToE of our universe should be self-contained. And whether or not another universe exists is beyond the scope of our scientific instruments as well as our quest at hand.

If the "math" points to multiple universes, then I am reminded again of your opener to this thread:
