Also, if it is both deterministic, and the universal wave function is real, I don't see how under QM this can lead to a unique history. (as the table indicates).

Is this many-worlds in denial? It seems to allow one observer to be in a superposition, relative to another. This is an example of an observer in more than one state at a time, which of course leads to multiple-outcome measurements. > are all local, i.e. no FTL. > Yes, but it seems all local (and valid) interpretations of QM allow measurements to have more than one outcome. > To that I would add the purely epistemic "non-intepretation" of Peres and > Fuchs. > "No interpretation needed" -- I can interpret this in two ways, one way is to just take the math and equations literally (this leads to Everett), the other is "shut up and calculate", which leads no where really. > > > >> 2.
