I haven't been stuck on anything. As I recall, VIc fell in love with his
theory that time reversal explains non locality. Few took his explanation
seriously, which had many holes (proof by hand waving as it was, and there
are precious few, if any professional physicists who take his proposal
seriously. It was in one of his early books IIRC, and no references to it
in the literature. And physicists are all over the map on this one, but
most find it baffling. I know what you've done. You've just cobbled
together some words that make you happy and create the illusion you
understand the phenomenon. Now you assume an arrogant position. You can say
the pairs are non separable and I wouldn't disagree with the words, but
when one side is measured randomly, the issue is how the other side adjusts
to keep momentum conserved if it is space-like separated. If the subject
was solved, as you falsely claim, there wouldn't be any resort to the MWI
to allege explanations. Like I said, you can enjoy your words, and they may
fool yourself, but not me. AG
