Universal Contradiction Helps Sort Out Quantum Mechanics!

Here we go again! Psyence at its ‘best’!

I wonder; if we do have parallel universes, then where is the coordination of quantum events being arbitrated/managed/coordinated? What functions as a substrate?

Isn’t the idea of a set of parallel (NOT multiverses which is something quite different!) begging the question?

Even Set Theory warns us of a contradiction that also arises, should we take this idea seriously.
