Four Gravitational-Wave Detections Include Largest, Most Distant Black Hole Crash Ever

Scientists have identified four more ghostly signals of massive collisions in outer space, including of the largest to date, bringing their total haul of gravitational-wave detections to 11 in just a few years. And even better, that wealth of observations is large enough to let scientists make broader discoveries about the world around us and the black holes that fill it.

A team of researchers affiliated with the Laser Interferometer Gravitational-Wave Observatory (LIGO) in the U.S. and its European counterpart Virgo unveiled the four new detections on Saturday (Dec. 1) at a scientific meeting.

"It took science a century to confirm Einstein's prediction of the existence of gravitational waves," Sheila Rowan, a physicist at the University of Glasgow in the United Kingdom, said in a statement. "But the pace of our discoveries since then has been exhilarating, and we're anticipating many more exciting detections to come."
