Do you not understand that one of the enduring mysteries of quantum theory is the emergence of the classical world from the purely quantum substrate? Decoherence goes a long way towards answering the underlying problems, but unless something intervenes to exactly zero the off-diagonal terms in the density matrix, the the understanding that we have is still only FAPP. But the emphasis here is on Practical, rabbiting on about the multiverse is not in the least practical, here or anywhere else.
Bruce Sometimes I read and re-read something Schroedinger seemed to have in mind. “The idea that [the alternate measurement outcomes] be not alternatives but all really happening simultaneously seems lunatic to [the quantum theorist], just impossible. He thinks that if the laws of nature took this form for, let me say, a quarter of an hour, we should find our surroundings rapidly turning into a quagmire, a sort of a featureless jelly or plasma, all contours becoming blurred, we ourselves probably becoming jelly fish. It is strange that he should believe this. For I understand he grants that unobserved nature does behave this way – namely according to the wave equation. . . . according to the quantum theorist, nature is prevented from rapid jellification only by our perceiving or observing it.” --Erwin Schroedinger, The Interpretation of Quantum Mechanics.
