Bell's theorem - for or against Hidden Variables?

[Heinera]

"In real Bell-CHSH experiments, we can't observe quadruples (A, A', B, B'). It is only the hypothesis of local realism that says that they do exist."

Exactly!  You have a hypothesis that is physically impossible to test.  So it is junk science to think that the experiments are testing the hypothesis.  They aren't.  They are only confirming that the predictions of QM are correct.  Which is good.

With Christian's exploding balls experiment, you obviously can observe the quadruples, so in that case it is possible to test.  Still junk science?
