Astronomers have discovered evidence for physics beyond Einstein's general relativity. This artist's conception shows a galactic black hole being orbited by a ripple in spacetime--a distortion in the fabric of space itself. Credit: Dana Berry (CfA/NASA)

This artist's conception shows the binary system GRS1915+105, which shows evidence for a wave of spacetime in its accretion disk. A 10 solar mass black hole at the center of the disk pulls gas from a nearby companion star. The gas spiraling into the black hole heats so much that it emits X-ray radiation.
