astronomyA Total of Ten Black Hole Collisions and a Neutron Star Collision Have Been Detected

No Comments
The LIGO and Virgo gravitational wave observatories report four more gravitation wave detections. The total number of gravitational waves we have every detected is now 11. Ten were caused by black hole collisions and one was by neutron stars colliding. …
