A Monster Black Hole Just Went Rogue, and It’s Racing Through Space at 1,600 KM/S

A runaway supermassive black hole has been observed racing through space at 1,600 km/s, leaving a 200,000-light-year trail of newborn stars behind it. This phenomenon provides strong evidence for the theory that gravitational-wave recoil can eject black holes from their galaxies. The black hole, estimated to be moving at roughly 1,600 kilometers per second, appears to have been displaced from its galactic center and is compressing gas ahead of it to ignite star formation.
