A black hole formed by a lopsided merger may have gone rogue
Astronomers have spotted the first evidence of a merger event that gave a black hole a kick that left it traveling at around 3 million mph — fast enough for it to escape its host galaxy.
Gravitational waves are ripples in space-time created by the interaction of massive objects in space, such as black holes and neutron stars. Their existence was first predicted by Albert Einstein in his 1916 paper describing his theory of general relativity. In 2015, scientists made the first detection of gravitational waves, observing ripples from the collision of two black holes. The discovery won astrophysicists Kip Thorne, Barry Baris and Rainer Weiss the 2017 Nobel Prize for Physics. Subsequent observations have also detected gravitational waves from colliding neutron stars. Learn more about gravitational waves here.
