Researchers estimate that it took the equivalent energy of 100 million supernovas exploding simultaneously to jettison the black hole. They have found a supermassive black hole being propelled out of the center of a distant galaxy believed to be due to gravitational waves. The black hole, a billion times massive than the Sun had traveled 35,000 light-years so far, NASA said. Notably, it was first predicted by Einstein gravitational waves are ripples in space that are created when two massive objects collide.
