Physicists Say They’ve Found The Origin Of Causality

Over the years, physicists have become increasingly enamored with “quantum weirdness,” the many strange features of quantum mechanics that are extremely hard to explain. In a new paper, a group of researchers have tried to cut through the weirdness by analyzing how causal order really works. By doing so, they hope to set up a deeper framework that can combine quantum mechanics with gravity. Let’s take a look.
