A third detection of gravitational waves is changing our understanding of black holes

For the third time, scientists have detected gravitational waves — the ripples in space-time created by objects moving throughout the Universe.

The discovery was made once again by LIGO, or the Laser Interferometer Gravitational-Wave Observatory Scientific Collaboration — the same team that last year made headlines for measuring gravitational waves for the first time in history. With each new detection, LIGO further solidifies that its measurements are sound, not just statistical blips. And now, researchers are starting to use these detections to learn more about distant space objects, as well as spot trends that they didn’t quite expect to see.

“There’s a famous saying: once is chance, twice is coincidence, and thrice is a pattern,”...
