- This is not true. You are no doubt referring to tests of Bell inequality.
- First Bell's result does not rule out deterministic causal theories. It
- only rules out *local* theories. In the early 50's Bohm constructed a
- non local causal model consistent with all the predictions of quantum
- mechanics.
-
- Second the experiments that confirm the predictions of quantum mechanics
- that Bell's inequality is violated are not conclusive. Aspect's experiment
- was widely considered to be conclusive at the time but Franson showed
- that Aspect did not prove that the correlated events he observed had a
- space-like separation. See the following for more details about Aspect's
- experiment:
