A Century-Long Endeavor Concluding a Billion-Year Voyage on Stormy Gravitational Waves
Earlier this year the LIGO collaboration announced the first direct detection of gravitational waves (GWs). Predicting gravitational waves exactly century ago, Einstein doubted they would ever be detected.
The GWs of two massive black hole violent coalescence over a billion years ago made their way to the upgraded ultra sensitive LIGO detector right after its recent commission. Not only Einstein's general relativity celebrates its most significant triumph, but the emerging new type of astronomy allows an authentic gravitational wave look at black holes as well as the very early universe, right after the Big Bang.
