A monster merger between two black holes sent ripples through time and space, and may prove Einstein right about a gravitational phenomenon called precession.

Scientists have, for the first time, picked up the ripples in space-time caused by the collision of a neutron star and a black hole.
Two instances of this violent cosmic event have been detected using the Advanced LIGO and Virgo gravitational wave detectors, details of which have been published today in Astrophysical Journal Letters.
Though previous gravitational wave detections have spotted black holes colliding, and neutron stars merging, this is the first time that scientists have detected a collision from one of each.
Dr Vivien Raymond, from Cardiff University’s Gravity Exploration Institute, said: “After the detections of black holes merging together, and neutron stars merging together, we finally have the final piece of the puzzle: black holes swallowing neutron stars whole. This observation really completes our picture of the densest objects in the universe and their diet.”
