The sharpest black hole collision ever detected just gave Einstein another win—and raised hopes that the next one might rewrite gravity.

Astronomers have found thousands of exoplanets around single stars, but few around binary stars—even though both types of stars are equally common. Physicists can now explain the dearth.
