The space is loaded with mystery and new ones get added to it with new discoveries. One such reservation was made a few days back that one more unevenly sized black hole pair was found by the gravitational force on 12th April, 2020. The tides in spacetime mixed up by two distant, merging black holes indicate that one of the pair was much larger than the other. It’s the first definitively mismatched black hole pair spotted by the LIGO and Virgo collaborations, which search for the gravitational waves radiated in the cosmic clashes of black holes. The collision was seen about 2.5 billion light-years from Earth.
For all previous such black hole consolidations, the two members were of identical sizes. But this time and for the first time, the bigger black hole had a mass about 30 times that of the sun, and the smaller was about eight times the mass of the sun which are not identical at all by size as announced by the researchers of the LIGO and Virgo collaborations on April 18 at a meeting of the American Physical Society, which was held virtually due to the COVID-19 pandemic.
Before this, scientists did not know if such uneven partnerships existed, or how rare they might be. “This one event represents a big step forward in our understanding,” astrophysicist Maya Fishbach of the University of Chicago said in a talk at the meeting.
