Gravitational Lensing: Bends in Spacetime - Livestream

One hundred years ago, Einstein predicted that light rays would bend in the space near a massive object - much as light rays refract in an optical lens. Today, we use this fact to weigh galaxies, to discover planets of other stars, and to “see” invisible black holes. How did this idea of gravitational lensing come about, and how do we use it today to probe all fields of astrophysics?
