Gravitational Waves The 2017 Nobel Prize in Physics

"Gravitational Waves:

The 2017 Nobel Prize in Physics”

by Rob Knop Ph. D, USA

Saturday 14th, 10 AM PDTThe 2017 Nobel Prize in Physics was awarded to leaders of the LIGO collaboration for the discovery of gravitational waves.  This phenomena was predicted a century ago by General Relativity, but it was always known that because they’re typically so small, they would be very hard to detect. 

Indirect evidence for them previously came from the decaying orbits of binary pulsars.  In 2015, the LIGO detectors announced the first direct detection of gravitational waves, a signal resulting from the merger of two very distant black holes. In this talk, I’ll describe the nature and history of gravitational waves, and the work that the large LIGO collaboration did to earn this Nobel prize.
