The Birth of Gravitational Wave Astronomy
When black holes collide they make waves in the fabric of space and time. At least that is what Albert Einstein predicted a hundred years ago. This talk describes the dramatic discovery of gravitational waves when, on September 14, 2015, the Laser Interferometer Gravitational Wave Obserrvatory (LIGO) in North America detected them. The signal was so clear that we can tell it came from the merger of two black holes that took place about a billion years ago. Gravitational waves were observed again on Boxing Day 2015 from another collision of black holes. The direct detection of gravitational waves is already considered one of the triumphs of science of the century and marks the dawn of a new era in astronomy. Gravitational wave detection is giving a new way to unveil some of the Universe's most well-kept secrets.
