Two supermassive black holes are heading for a cosmic mega-collision

quasar

If you’re weary, feelin’ small, remember that somewhere out there, two supermassive black holes are heading for a cosmic mega-collision. Earlier this year, astronomers at Caltech identified a cosmic event that is occurring 3.5 billion light years from Earth: two supermassive black holes spiraling helplessly towards each other. Recent work by researchers at Columbia University adds further evidence that indeed the black holes are on a collision course. The consequences are not yet completely clear, but this meeting will certainly be cataclysmic for nearby stars and planets.
