TY, AG* *If it's in one and only one definite state but we just don't know which one then that situation is by definition "realistic", and the falsification of Bell's Inequality cannot rule that out, BUT if it is realistic then locality or determinism or both must be false. Whatever turns out to be correct there is one thing we can be certain of, Quantum Mechanics is weird. * John K Clark See what's on my new list at Extropolis <https://groups.google.com/g/extropolis> lgr *In physics "realism" means something is in one and only one definite state even if it has not been measured. The fact that Bell's Inequality has been experimentally found to be falsified means that physics cannot be realistic **IF** it is deterministic** and it is local, that is to say if a changing force is always weakened by distance and cannot operate faster than the speed of light. Many Worlds is not realistic but it is deterministic *and* local so it is compatible with the falsification of Bell's Inequality. Pilot wave theory is realistic and deterministic but not local so it is also compatible with Bell. Objective collapse theories are realistic and local but not deterministic **thus* they* to*o* are compatible with Bell**. So no fundamental theory of reality that agrees with experimental results can be realistic and local and deterministic, it must give up at least one of those three things. * *As for Copenhagen, it's not deterministic that much at least is clear, but even the believers in it can't agree among themselves if it's local or realistic or both or neither because few seem to know exactly what the Copenhagen interpretation is, but I think I do. The Copenhagen interpretation is bad philosophy.* -- You received this message because you are subscribed to the Google Groups "Everything List" group.
