Explore the cutting-edge world of gravitational wave detection in this 1 hour 34 minute panel discussion from the World Science Festival. Join moderator Marcia Bartusiak and renowned scientists Kip Thorne, Laura Danly, and Rainer Weiss as they delve into the groundbreaking LIGO (Laser Interferometer Gravitational-wave Observatory) project. Discover how this revolutionary technology aims to capture cosmic whispers of distant celestial events, potentially opening a new window for observing the universe through gravity rather than light. Trace the journey from Einstein's 1916 General Theory of Relativity to the present-day efforts to detect gravitational waves. Learn about the history of gravity, the universal rate of acceleration, and what prompted Einstein to challenge Newton's ideas. Explore fascinating topics such as black hole collisions, binary pulsars, and the concept of measuring the universe's strain. Gain insights into the LIGO detectors, their functionality, and the potential surprises awaiting discovery in this new field of astronomy.
