Physicists around the world confirmed they had detected unambiguous signals of gravitational waves emanating from the collision of two massive black holes 1.3 billion light years away in deep space. “The observation of GW150914 marks three milestones for physics: the direct detection of gravitational waves, the first observation of a binary black hole, and the most convincing evidence to-date that nature's black holes are the objects predicted by Einstein's theory,” said Professor Alberto Vecchio of the University of Birmingham’s School of Physics and Astronomy. They had directly witnessed gravitational waves for the first time, and precisely 100 years after Einstein’s general theory had predicted them. Both of Ligo’s two observatories in Washington and Louisiana detected the same gravitational waves almost simultaneously – meaning the find has a statistically significant level of “sigma 5” — virtually ruling out a chance effect.
