What does this even mean?

This is correct. Note how you shift your ground here: you say "history" instead of "quantum state". There is only one quantum state in...

Btw, to put this observation of mine in context, I have this condition...

Will that be permanent, or will it go away at some point?

@Greg Bernhardt. Several other forums that I'm on have the capability to conduct polls. Does the Physics Forum website software support...

Yes.

Bohmian mechanics would be one obvious case: the particle positions and velocities are the state of the particle, just as in Newtonian...

As an example, you said that it would be meaningless to say that a classical particles is the same as its position and momentum. But I...

And note that the original question by @Demystifier that prompted this subthread, in context, was: That looks to me like he was asking...

If you give it the literal intepretation you are, yes. But many would not; they would just interpret it as shorthand for what I...

In the sense I described in post #110.

Any reference by an MWI proponent. But see my post #110 in response to @Fra for some more unpacking.

That depends on which interpretation of QM you adopt. You appear to be adopting an "information interpretation", where the wave function...

It is in the MWI.

Not really. Pauli first formulated the exclusion principle in 1925, but then it was just an ad hoc assumption. Proving it required the...
