Strange signals from space Fast Radio Bursts - Long far and ago away, a duo of dancing supermassive black holes look like spiraling in towards the other person, eventually doomed to collide inside a stupendous, almost unimaginable, cosmic smash-up. Dancing at night, the strange pair will merge a mere million years from now, liberating energy comparable 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 in the end merge, growing increasingly more massive consequently, so too do their hearts of darkness. Within the January 7, 2015 issue from the journal Nature, a team of astronomers report on a weird repeating light signal coming from a distant quasar they say is most likely caused by a duo of dancing supermassive black holes in the last act of a merger--something that is predicted from theory but which has never been seen before! A quasar is certainly a brilliant, luminous object that out-dazzles each of the stars in their host galaxy combined, and is visible from over the entire Universe!
