In a rare astronomical event, scientists have observed light from the merger of two black holes in the distant universe. If confirmed, it could be the first known light flare from a pair of colliding black holes. Embedded in this disk are two smaller black holes that may have merged to form a new black hole. The merger of the …
Black holes are getting stranger even to astronomers. They’ve now detected the signal from a long-ago violent collision of two black holes that created a new one of a size that had never been seen before. Star collapses couldn’t create stellar black holes much bigger than 70 times the mass of our sun, scientists thought, according to physicist Nelson Christensen, …
When the universe was half the age it is now — around 7 billion years ago — two massive black holes crashed together. Key points: Astronomers have detected gravitational waves from a monster black hole collision, almost twice the mass of anything detected in this way before It is the first time astronomers have observed the birth of a black …
