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

By Meghan Bartels, Space.com Senior Writer | December 4, 2018 06:47am ET

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."

Gravitational waves are often described as "ripples in space-time" and are produced by pairs of black holes or neutron stars which are two forms of extremely massive, dense remnants created when a star explodes. Pairs of these objects orbit each other, drawing ever closer to one another and causing gravitational waves to ripple outward as they do so, until they eventually collide.

1. This is silly analysis

Obviously these scientists haven't considered the fact these Gravitational-Wave Detections are simply ECHOS with only a fraction being the original waves from which they came from. Just dumb science.
