binary black holes

Binary black holes are two black holes that orbit each other due to their mutual gravitational attraction. Over time, they spiral closer together, emitting gravitational waves—ripples in spacetime—which can be detected by specialized observatories. As they merge, they form a larger black hole, releasing a tremendous amount of energy. This process helps scientists understand extreme gravity, stellar evolution, and the fabric of the universe. Although black holes themselves are invisible, their interactions and the gravitational waves they produce provide valuable insights into these mysterious cosmic objects.
