However others point out, and I tend to agree with them, that the collapse only affects a localized region of the wave function, so it would be impossible even in theory, much less in practice, for an observer to tell the difference between the collapse happening instantaneously and the collapse propagating outward at the speed of light; so if you say Objective Collapse is local then you can be sure that there will never be an experimental result that proves you wrong. * *For the same reason I'd call Many Worlds a local theory, but it's deterministic and unrealistic. Pilot Wave is realistic and deterministic but very definitely non-local. All these theories can explain the violation of Bell's Inequality, but Einstein Realism cannot.* *Superdeterminism can also explain the violation of Bell's Inequality, and it's deterministic, realistic and local. But Superdeterminism has one other interesting characteristic that none of the others have, it is idiotic. * * John K Clark See what's on my new list at Extropolis <https://groups.google.com/g/extropolis>* 2bb -- You received this message because you are subscribed to the Google Groups "Everything List" group.
