Fast Radio Bursts - Long ago and far away, a duo of dancing supermassive black holes appear to be spiraling in towards one another, eventually doomed to collide inside a stupendous, almost unimaginable, cosmic smash-up. Dancing at night, the strange pair will merge merely a million years from now, liberating energy equal to 100 million supernova blasts, where massive stars perish. If not all, large galaxies in the Universe--including our own Milky Way--contain supermassive black holes with masses equivalent to millions, or even billions, of Suns, and these objects of incredible darkness and their host galaxies appear to evolve together, or "co-evolve", the dark-hearts of most. Theory predicts that as galaxies collide and ultimately merge, growing increasingly more massive because of this, so too do their hearts of darkness. Within the January 7, 2015 issue of the journal Nature, a team of astronomers report over a weird repeating light signal from a distant quasar they say is most probably caused by a duo of dancing supermassive black holes in the last act of the merger--a thing that is predicted from theory but which includes never been seen before! A quasar is an extremely brilliant, luminous object that out-dazzles all of the stars in its host galaxy combined, and is also visible from throughout the entire Universe!
