Black Hole Collisions Tell a Tale of Repeating Mergers

Black Hole Collisions Tell a Tale of Repeating Mergers

A black hole merger is one of the Universe's most energetic and massive events. During such a collision, two black holes orbit closer and closer until they collide and become a much more massive black hole. The event also gives off radiation and, as it happens, gravitational waves. They help tell the story of the two objects involved in the collision.
