Astronomers may have detected the most massive collision of two black holes ever discovered, a chaotic merger that occurred some 7 billion years ago, the signs of which have only just reached us. The cataclysmic event offered researchers a front-row seat to the birth of one of the Universe’s most elusive objects.
The distant show included two major players: one black hole roughly 66 times the mass of our Sun, and another black hole roughly 85 times the mass of our Sun. The two came close together, rapidly spinning around one another several times per second before eventually crashing together in a violent burst of energy that sent shockwaves throughout the Universe. The result of their merger? One single black hole roughly 142 times the...
