This is the third time that gravitational waves have been detected by the twin Laser Interferometer Gravitational-Wave Observatory (LIGO) detectors, further opening the door to a whole new way to observe our universe. The new work is published in Physical Review Letters.

„From this discovery, we can learn more about how stars actually explode,“ said the University of Toronto’s lead researcher on the project, Harald Pfeiffer, who is an associate professor from the Canadian Institute for Theoretical Astrophysics. He’s part of the LIGO collaboration, which includes about 1,000 scientists worldwide. „It is further confirmation that there’s a large number of colliding black holes in the universe,“ he told me over the phone.
