But the effect of A's measurement result on B's wave function does not cease, because of the effective collapse when A is measured, as...

Before we can even talk about the other cases you mention, we first have to be clear about the simplest case, where A and B both exist...

No, that's not what we have agreed to. See my post #84 just now, which "crossed in the mail" with yours, so to speak.

No, BM does not say that. BM says that the wave function changes instantaneously and nonlocally because of the "effective collapse"...

What (effectively) collapses is not B's "spin component", it's the wave function. That contains information about all spin components...

This kind of reasoning implicitly assumes that the wave function is the state of the particle. As I emphasized again in post #77 just...

What I quoted from my post #67 in my post #76 just now should answer this. But to unpack it once more: The "effective collapse" induced...

Yes. Now compare with what I said in post #67: This is what @Demystifier meant when he said "of course". Then I gave more details to...

Norsen's NO is correct. See my post #67 (and my posts #61 and #62 that it refers to). If you mean anything else in the universe other...

I don't think you've misrepresented Norsen. I'm having difficulty understanding why you seem to think @Demystifier (and possibly I)...

No, I was disagreeing with your claim that @Demystifier's posts are in disagreement with Norsen. They're not. Yes, and nothing I or...

No, they're not. Remember that in BM, the particle is just like a classical particle obeying an equation of motion--but the equation of...

This is not correct. The part of the pilot wave that appears in B's Hamiltonian always affects B. What is true is that the part of the...

He isn't. What he's emphasizing is that in BM, the wave function is not the state of the particle. The state of the particle is the...

But we can also say, knowing the result of the ##A## measurement, that only the portion of the ##B## pilot wave that is in the collapsed...
