During the observation of the merging event of two black holes, scientists discovered something special about the resulting black hole. This object shot away at speeds of up to 698 km/s, or about 2.5 million km/h; Black holes fly at high speed due to receiving energy by a “shot” with a speed of up to 18 million km/h.
When two black holes collide, gravitational waves will form, disturbing the spacetime background. From two gravitational wave observation stations LIGO (USA) and Virgo (Italy), scientists detected a series of waves flying towards the Earth’s area on January 29, 2020.
The special wave describes in detail how two black holes merge, and shows a special effect produced when two black holes collide. As they orbited each other, the space plate wobbled like a spinning top running out of kinetic energy.
According to astrophysicist Vijay Varma of the Max Planck Institute for Gravitational Physics (Germany), it is possible to compare the event of two black holes merging with a gun that recoils when a bullet is fired, and gravitational waves. The other guide is the ball that vibrates the space. Gravitational waves fly in one direction, the black hole formed after the merger event will fly in the opposite direction.
Black holes flying away at high speed can help us unlock many new things. The LIGO and Virgo observatories are capable of detecting merging events of stellar-mass black holes, which form when a star explodes as a supernova and collapses into a black hole.
The scientists wanted to determine if black holes in a cluster would constantly pair up to form giant black holes. But it seems, when the finished black hole is shot away at a speed of millions of km/h, the ability to pair with the black hole of the same cluster is noticeably lower.
According to astrophysicist Manuela Capanelli, a scientist from the Rochester Institute of Technology, who was not involved in the study, such a high velocity shot is not surprising. Previously, it was Capanelli and his colleagues who proposed the theory of the astronomical phenomenon described in the new report. “It’s interesting when someone observes and measures what you predicted based on calculations,” said the physicist.
