Physicists at the University of Vienna conducted an experiment demonstrating that quantum events can exist in a superposition of different temporal orders, suggesting causality may not be fundamental to quantum mechanics. Using entangled photons and a Bell inequality test, researchers found results 18 standard deviations from classical predictions, though the experiment contains loopholes that future work could eliminate.
