Black Holes, Too! Gravitational Wave Find Had Other Surprises

For the first time in history, scientists have physical proof that pairs of black holes will sometimes circle around each other, collide and mush together to form a single, bigger black hole. This news of binary-pair detection is extremely significant for astrophysicists, but it was somewhat eclipsed by the simple fact that the Large Interferometer Gravitational Wave Observatory (LIGO) had detected gravitational waves at all.
