LIGO Detects Gravitational Waves for Third Time

Northwestern Now reported on June 1, 2017 that “One, two and now three historic waves have come from deep space.”

The press release reads: “The Laser Interferometer Gravitational-wave Observatory (LIGO) made the detection Jan. 4, 2017, demonstrating that a new window in astronomy has been firmly opened. Gravitational waves pass through Earth and can be “heard” by the extremely sensitive LIGO detectors. As was the case with the first two detections, the waves were generated when two black holes merged to form a larger black hole.

The long-awaited triumph in September 2015 of the first-ever direct observation of gravitational waves completed Einstein’s vision of a universe in which space and time are interwoven and dynamic.”
