SETI - Long far and ago away, a duo of dancing supermassive black holes seem to be spiraling in towards one another, eventually doomed to collide in a stupendous, almost unimaginable, cosmic smash-up. Dancing at night, the strange pair will merge only a million years from now, liberating energy equal to 100 million supernova blasts, where massive stars perish. The dark-hearts of most, 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". Theory predicts that as galaxies collide and in the end merge, growing a lot more massive because of this, so too do their hearts of darkness. In the January 7, 2015 issue of the journal Nature, a team of astronomers report on a weird repeating light signal coming from a distant quasar that they say is most probably caused by a duo of dancing supermassive black holes during the last act of any merger--something which is predicted from theory but that has never been seen before! A quasar is definitely a brilliant, luminous object that out-dazzles each of the stars in their host galaxy combined, and is visible from over the entire Universe!
