I have read that these experiments have been successful and do not cause a disagreement with QM. But I can’t quite determine what was learned. So what did they prove or disprove? Is there a simple explanation? I thought they were designed to determine if wave collapse breaks either locality or causality? (Non-Locality – instant action at a distance. Non-Causality – action goes back in time. I think I have that part right.) It should be one or the other, right?
