The way the Nobel Committee tells it, the story of this year’s physics prize begins like a certain 1970s space opera. “Once upon a time, a long time ago, in a galaxy far, far away, two massive black holes engaged in a deadly dance,” said physicist and Nobel committee member Olga Botner at today's prize announcement. The pair spiraled toward each other, colliding to form an even bigger black hole with a mass 62 times that of Earth's sun.
