See my answer to spudboy. There is no matter, and 0 physical universe, just the computations emulated by the +/* structure of arithmetic; that is, all computations. That include the quantum one, but that does not explain the quantum one. To explain them, we have to prove that only them win the first indeterminacy problem in arithmetic (or there will be an appel to something non Turing emulable or first person recoverable. But even with quantum mechanics, that problem can be solved, as the laws are statistical, and the universe never interact. Linearity precludes us to steal the oil in a parallel universe. Amazingly, if QM was not 100% linear (if the wave equation was only the first term of some series) we would be able to interact in between universe, but thermodynamic would get wrong, relativity would become wrong, well, nobody try this anymore.
