Gravitational waves point scientists to elusive missing- black hole

The report stated "From that information, astrophysicists can calculate the distance at which a collision occurs — about 7 billion light-years away, in this case. Scientists can also calculate the sizes of the two objects that collided, in this case 85 and 66 times the mass of our sun, and of the resulting object, about 142 times the mass of the sun. (During a collision, some mass is lost as the energy of gravitational waves.)"

My observation. The 142 solar mass black hole has a 4.1936E+02 km Schwarzschild radius, and diameter 5.6065E-06 AU.
