I'm arguing that time is symmetric, and that hence Bell's (implicit) 4th
assumption is violated. Bell agreed that this was true, but said the
assumption was valid - he thought time was asymmetric at all levels.
Physics indicates he was wrong (wrong when it counts in EPR experiments,
I don't know why there is so much fuss over Bell's inequality, and so much
mystical mumbo jumbo about non locality and spooky action and so on, when
it was actually discovered before Bell died that there's a perfectly
reasonable explanation for how his inequality can be violated that retains
locality and realism. It's like physics being sime symmetric is so "far
out" that no one can believe it, yet it requires no new physics and fixes
up all those problems!
