Re: Is Bohm Hidden Variables discredited or not? How?

The EPR paradox was not discredited, it was resolved, in favor of QM.

This does not make much sense. Do you understand your own question?

The link?

No. The double-slit diffraction experiment can be explained
nonrelativistically, and the predictions of the Bohm theory in this
case are provably absolutely identical to those of nonrelativistic QM.
There is no way the Bohm model can be "disproved" by a measurement of
this sort.
