Scientists spot flash of light from colliding black holes. But how?
Scientists spot flash of light from colliding black holes. But how? Scientists think they identified two black holes merging that produced a burst of light. Black holes aren’t supposed to make flashes of light. It’s right there in the name: black holes. Even when they slam into each, the massive objects are supposed to be…
