“[A] team of European researchers decided to model an event that should be relatively uncommon: the two black holes didn’t start out in a mutual orbit but happened to pass close enough to gravitationally latch onto each other. … The models that produced a chirp that best matched the GW190521 signal saw a single pass that drew the black holes closer, followed by a single rapid curve into the collision.”
