Quantum Theory Fails Reality Checks
Reality just got a one-two punch. A new experiment has tried to suss out which of two counterintuitive ingredients is more basic to quantum theory, only to find that they go hand in hand.
Einstein was famously bugged by what are now well-established facts of quantum theory: the randomness of a particle’s choices and the possibility of instantaneous linkages between far-flung light or matter. Experimenters now conclude that Einstein cannot even pick his poison, because allowing for instant links kills any simple notion of reality, too.
