The Discovery of Gravitational Waves
On September 14th, 2015, LIGO (the Laser Interferometer Gravitational-Wave Observatory) detected the echo of colliding black holes in a galaxy far, far, away. Prof. Daniel Holz summarizes Einstein’s theory of gravity and its prediction of gravitational waves. He then presents the fascinating methods used to detect gravitational waves, and tell us the compelling and gripping story of their recent discussion. He concludes us by telling us what we have learned about black holes and the universe, and what this discovery means for the future of astronomy.
