Lynford Lecture: LIGO and the Dawn of Gravitational Wave Astronomy
On September 14, 2015 scientists observed the collision and fusion of two black holes using the Laser Interferometer Gravitational-Wave Observatory (LIGO.) For the first time they were able to measure the gravitational waves emitted during their collision and detection and which came 100 years after Einstein developed his revolutionary general theory of relativity that predicted their existence. These discoveries have profound implications for physics and astronomy, revealing unique insights into the nature of gravity, matter, space, and time. Dr Fritschel will talk about how these detections were made and discuss how gravitational wave astronomy promises to change our understanding of the universe.
