A binary black hole is a system of two black holes that are in orbit around each other. Binary black holes are thought to be formed when two massive stars, each of which has exhausted its nuclear fuel and collapsed into a black hole, come close enough to each other to be gravitationally bound.
As the two black holes orbit each other, they emit gravitational waves, which cause their orbits to decay and eventually merge into a single black hole. This process is known as a black hole merger or gravitational-wave merger.
Binary black holes are important objects of study in astronomy and astrophysics because they can provide insights into the fundamental properties of black holes, such as their mass, spin, and gravitational-wave emission. The detection of gravitational waves from binary black hole mergers, first observed in 2015 by the LIGO and Virgo collaborations, has opened up a new era of gravitational-wave astronomy and has confirmed the existence of black holes predicted by Einstein’s theory of general relativity.
Studying binary black holes can also provide clues about the formation and evolution of galaxies and the structure of the universe itself. Read More about School Management System.
