The result highlights a fundamental tension: Either the rules of quantum mechanics don’t always apply, or at least one basic assumption about reality must be wrong.
Recent experiments show that particles should be able to go faster than light when they quantum mechanically “tunnel” through walls.
Physicists have identified an algebraic structure underlying the messy mathematics of particle collisions. Some hope it will lead to a more elegant theory of the natural world.
Anyons don’t fit into either of the two known particle kingdoms. To find them, physicists had to erase the third dimension.
Two ways of approximating the ultra-complicated math that governs quark particles have recently come into conflict, leaving physicists unsure what their decades-old theory predicts.
