A double whammy of gravitational waves sparks a burst of black hole speculation
Artwork shows the merger of two black holes, which gives off a burst of gravitational waves. (SXS Graphic) Two detections of gravitational waves, separated by a mere 21 minutes, set off a flurry of excitement among astronomers today. Was it a binary black-hole merger? A double observation of a single black-hole merger, created by gravitational…
