Laser Interferometer Gravitational-Wave Observatory Lab has detected the occurrence of third gravitational waves by the merger of two black holes.

Third gravitational wave has been detected by the Laser Interferometer Gravitational-Wave Observatory (LIGO). The detectors in the United States have detected the occurrence due to the merger of two black holes.

This is the third gravitational wave detection by LIGO first being detected in 2015. It was then that scientists started believing that massive black holes do exist. A senior scientist with LIGO collaboration in the Unites States said illustrates the first detection to be by chance, the second one as a coincidence and the third one as a pattern followed.

Black holes are said to have masses nearly 31 times and 19 times than that of the sun. Along with the gravitational waves, the alignment of spins of the black holes was also recorded by the scientists. They also observed that the merging black holes don’t tend to align along the same direction. This is very well in accordance with the theory that black holes are formed independently in a star cluster which then concentrate to the centre and merge. The detection is also supported very well by Einstein’s The General Theory of Relativity as the gravitational waves detected didn’t disperse while travelling through space.

India has majorly contributed to many studies and a LIGO lab will be set up in India by 2024, the first two being in the United States.
