black hole mergers

Black hole mergers occur when two black holes orbit each other and eventually collide, merging into a larger black hole. This process is driven by gravitational waves, which are ripples in spacetime that carry energy away, causing the black holes to spiral together. When they merge, they release immense energy, producing detectable waves that astronomers can observe from Earth. These events provide insights into the nature of gravity, the formation of black holes, and the dynamics of the universe. These mergers are significant cosmic events that help scientists understand the fundamental workings of space and time.
