Gravitational waves from colliding black holes detected again

Two black holes whirled violently towards each other, under the pull of the immense gravity between them, combining into a mass around sixty times that of our own sun.

They collided with such force they created a disturbance in spacetime itself. In September of 2015, the disturbance made itself known on Earth as an infinitesimal shiver in two 2.5-mile-wide L-shaped tubes. In December, the day after Christmas, the tubes shivered again.

"Its wonderful," David Shoemaker, Director of the Massachusetts Institute of Technology's LIGO lab, told Popular Science. "Its so different from the first one ... but its importance is no less."
