Physicists have directly observed a long-predicted quantum effect of gravity, putting one of Einstein's foundational ideas to a striking new test. Using ultracold atoms, researchers split an atom's quantum wave so that one part was held in place while the other fell freely under gravity, then reunited the two to measure the tiny difference that emerged.
