How Do You Detect a Black Hole? - LIGO and the Measurement of Gravitational Waves

Explore the groundbreaking detection of gravitational waves and black holes in this 31-minute video from the World Science Festival. Join moderator Brian Greene and LIGO Collaboration member Vicky Kalogera as they delve into the inner workings of the LIGO detector, the most precise measuring device ever built by humans. Learn about Einstein's theory of gravitational waves, the nature of LIGO, and how it detected these elusive ripples in spacetime. Discover the causes of gravitational waves, how their signals are converted into sound, and the process of calculating and simulating these cosmic phenomena. Investigate the detection of neutron star collisions and their implications for our understanding of the universe. Gain insights into how these discoveries are putting Einstein's theory of general relativity to the test, expanding our knowledge of black holes and the fabric of the cosmos.
