Gamma-Ray Burst Detected Near Gravitational Wave Source

On Sept. 14, 2015, our planet experienced a very slight spacetime ripple that was detected by the Laser Interferometer Gravitational Wave Observatory (LIGO). On analyzing the signal, physicists realized these gravitational waves were caused by a black hole merger, some 1.3 billion light-years away. This first gravitational wave event was dubbed “GW150914.” Continue reading Gamma-Ray Burst Detected Near Gravitational Wave Source

Hawking: Gravitational Waves Could Revolutionize Astronomy

In the wake of last week’s historic announcement of the discovery of gravitational waves by the Laser Interferometer Gravitational-Wave Observatory (LIGO), British physicist and black hole theorist Stephen Hawking was quick to congratulate the US-led collaboration, sharing his excitement for the historic news.
