- The LIGO and Virgo Gravity Wave Observatory confirmed that the largest double black hole fusion which was detected in 2019.
- The signal has been named GW190521 and likely represented the instant that the two black holes merged.
- The masses of the two black holes were 66 and 85 times that of the Sun.
- And they eventually merged into a black hole with a mass of 142 times that of the Sun.
- The black hole with 85 solar masses falls in an “intermediate-mass” range (first-ever to be observed)
- It defies the traditional knowledge of how black holes are formed.
- A solar mass is the mass of the sun or more precisely.
- It is 1.989 x 1030 kilograms, which is equivalent to about 333,000 Earths.
- Black holes 100-100,000 times the mass of the sun are called intermediate mass black holes.
