Quantum interactions that defy relativity might be particles reacting to events in their past
On the quantum level, cause-effect relationships aren't as easy to observe and link as you'd think. Heck, these particles' movement are decided by basically blindfolding yourself and throwing a dart at a chart of a probability wave. According to the abstract of a new paper from the American Journal of Physics, "the causal arrow of time" can essentially flip and go into reverse in quantum mechanics. This would mean that local causality from local interactions in the past can cause reactions in the present at a time where the particles are separated. This may reconcile some quantum behavior that seems to defy relativity. Further work based on this will challenge the physics community to rework their mathematical formulas and test test test it all out.
