All that the experiments demonstrate is that the wave function evolves
unitarily between state preparation and measurement. This is most
easily accounted for by assuming that the wave function is a purely
epistemic vehicle for the time evolution of probabilities. Since it is
purely epistemic, collapse is not a problem since it is not a physical
event. One does not have to go the whole way to QBism -- the wave
function can still be objective (inter-subjectively agreed).
That's possible but that means that QM is not a complete fundamental
theory of reality. Anything that explains these probabilities is then
possible, including the existence of a multiverse.
Which is about as explanatory as "God did it." Explaining the values of
the probabilities isn't the problem with MWI, it's explaining that
there *are* probabilities even though nothing happens, and when and
where the probabilities arise.
