This may be a little off topic, but the way I see it is that the issue, problem, or source of confusion is that Einstein was referring to a SINGLE case of a 2-photon system, whereas nearly everyone else is arguing from an ensemble of identically prepared systems. By the way, how do we KNOW each...
From the 1st paper cited above:
"Why, then, do many people wrongly claim that quantum mechanics is nonlocal? They do so by denying at least one of three fundamental precepts of QBism: (1) A measurement outcome does not preexist the measurement. An outcome is created for the agent who takes the...
I suggest that until we have a theory that predicts exactly where an individual photon will hit the screen in a 2-slit experiment, and the path of an individual gas atom in a confined space, and why one atom of uranium decays and not the one next to it, etc., we will not have a complete physical...
I can't be taken seriously, for I know nothing of higher mathematics. But I do have two reasons for questioning:
1. The measurement problem;
2. Gravity
In my view the tasks are:
1. DEduce THE dynamics for spin+detector.
2. Show that those dynamics hold for any and all measurements.
I agree that it "seems to be" an undisputed fact. Could this be in the realm of "appearances can be deceiving"?
BTW, I am NOT an MWI adherent.
