Two black holes locked in cosmic dance near galaxy’s center are doomed to crash

Two huge black holes are locked together by gravity as they inevitably spiral towards a collision, researchers have found in a new study.

Researchers in a new study have spotted two supermassive black holes that whip around each other every two Earth years, on average, with respective masses each of hundreds of millions of times that of our sun. They found that the pair are also relatively close, being only about 2,000 Earth-sun distances apart (or about 50 times the distance between the sun and Pluto.)
