That’s just the Boltzmann’s brain problem, right? It goes away if you assume our universe started with very low entropy for some reason other than pure Boltzmann-style chance. (I believe some theories, like String theories, provide this feature?) It seems to be an open problem in physics/cosmology.
I don’t understand QM. But intuitively I would expect that even in many-worlds, with an unbounded configuration space, the sum of probability over all configurations is (should be?) constant. Is that so, and would it solve the Boltzmann problem by reducing it to another (unsolved) problem, namely the origin and meaning of the Born probabilities?
