Gravitational Waves: Detection and Implications

This lecture covers the history, detection, and implications of gravitational waves. Starting from the first prediction by Einstein in 1916 to the first detection in 2016 by the LIGO experiment, the instructor explains the origins, detections, and future prospects of gravitational waves. The lecture delves into the technical aspects of gravitational wave astronomy, including the typical size of large-scale structures revealed by galaxies, the growth of density fluctuations, and the correlation function. It also explores the historical milestones in the field, such as the detection of binary pulsars and the implications of gravitational wave astronomy on our understanding of the universe.
