The detection of gravitational waves (GW) is a major achievement in physics and astrophysics. Up to now, more than 30 GW events resulting from the merger of compact celestial bodies have been observed by LIGO and VIRGO. Because electromagnetic radiation is the main method for studying astrophysical processes, whether physics can be combined with astronomy depends on whether the corresponding body of gravitational wave events can be found on electromagnetic radiation. Unfortunately, only the electromagnetic counterparts of the twin neutron star merger are currently seen. In gravitational wave astronomy, a very important subject is: Is it possible to generate electromagnetic radiation when the two black holes’ merge? In this essay, the dynamic process of the gas disk surrounding the binary black hole is studied through numerical simulation, and the long-term evolution process of these gases on the cosmological time scale is studied at the same time. The evolution process of the gas disk of the ring binary black hole can be obtained, which provides a theoretical limit on whether the electromagnetic counterpart of the merger of the binary black hole can be seen in the future.
