Dancing in the dark, the strange pair will merge merely a million years from now, liberating energy equal to 100 million supernova blasts, in which 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. In the January 7, 2015 issue from the journal Nature, a team of astronomers report over a weird repeating light signal coming from a distant quasar which they say is probably the result of 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 all of the stars in the host galaxy combined, and it is visible from across the entire Universe!
