David Reitze, Executive Director of the LIGO Laboratory at Caltech in the United States, gave this lecture in December 2016.He presents the revolutionary discovery of gravitational waves through the LIGO project and how this observation has opened a new window for exploring the universe. The talk details the physical principles behind detection, the technological advances required, and the experimental challenges overcome to measure such tiny disturbances in space-time. It also showcases groundbreaking results that confirm predictions from general relativity and explains how the mergers of black holes and neutron stars act as cosmic beacons, allowing astronomers to study previously invisible events from a new perspective.

This lecture is part of the astrophysics series ‘The Science of the Cosmos, the Science in the Cosmos’, tackles the fundamental questions in contemporary astrophysics. The fifth edition explores issues such as cosmic rays and anti-matter, the evolution of galaxies and the role played by black holes, the exploration of the Solar System, and the detection of gravitational waves.
