Largest ever celestial collision reveals a new kind of black hole

A collision of two black holes occurred a staggering five billion light years away, but the vibrations were strong enough to rattle sensors here on Earth

The result is likely to spur a host of new questions about how these black holes form and what that may say about the evolution of the universe and the laws of physics. “This is a huge discovery in that it’s the first conclusive observation in any medium of intermediate mass black holes,” said Jess McIver, an assistant professor at the University of British Columbia and a member of the collaboration.

What has not been established until now is the existence of black holes of intermediate size — approximately one hundred to 1,000 times the sun’s mass — which are not associated with the centre of a galaxy but which are too large to form through the collapse of a single star.

Not only was the black hole collision the largest and most distant emitter of gravitational waves ever detected, it verifies the existence of a new class of object known as intermediate mass black holes.

In this case, two black holes, one 85 times the mass of our sun and the other 66 times the mass, merged in an instant to form one much larger black hole totaling 142 suns, researchers involved in the detection revealed on Wednesday.

Since the 1970s, there has been ample evidence for black holes of this type culminating in the first detections by LIGO, the Laser Interferometer Gravitational Wave Observatory, starting in 2015.

Scientists say most of that mass was converted directly into gravitational energy that caused the very space around the black holes to stretch and heave like a stormy sea.

The finding may also show how the supermassive black holes at the centres of galaxies got started earlier on in cosmic history. “In a way it’s kind of an evolutionary missing link,” said Dr. McIver.
