Ten years is such a short little blip on cosmic timescales, but 10 years is all it's taken for the brightness of this supermassive black hole
to dim by an order of magnitude.
If such black hole
mergers occur in nature, next-generation gravitational wave observatories like the Evolved Laser Interferometer Space Antenna might provide proof of their existence.
The observation result shows that there is a unique chemical composition characterized by enhancement of hydrogen cyanide (HCN) around the black hole
, which would be caused by high temperature heating of the environment surrounding the black hole
According to the Schwarzschild solution of the Einstein general theory of relativity , the radius of a black hole
with mass [M.
But it wasn't the kind of black hole
created when a star explodes and dies; it was hundreds of thousands of times as powerful - a super-massive black hole
, as they are known.
The pulse has been created by gas being sucked by gravity on to the black hole
