Beyond Einstein - Gravitational Echoes: Light Waves and Black Holes

Explore the fascinating world of gravitational echoes in this 36-minute video from the World Science Festival's "Beyond Einstein" series. Delve into the exotic physics governing black holes as renowned researchers Erin Kara and Shep Doeleman join Brian Greene to discuss how light waves can echo off these cosmic phenomena. Learn about Karl Schwarzschild's contributions during World War I, the intricacies of non-rotating black holes, and the groundbreaking techniques used to capture images of these elusive objects. Discover the concept of light echoes, experience the sonification of black hole echoes, and understand the workings of the Event Horizon Telescope. Gain insights into how light travels around a black hole and challenge your understanding of Einstein's theories. This thought-provoking discussion covers a range of topics from confirmed scientific findings to highly speculative ideas, advancing our comprehension of fundamental physical laws and pushing the boundaries of our understanding of gravity in extreme conditions.
