TED: What the discovery of gravitational waves means | Allan Adams

The video discusses the collision of two black holes, which generated gravitational waves detected by LIGO. It highlights the journey of LIGO's development, the challenges in detecting gravitational waves, and the significance of these discoveries. LIGO acts as an auditory tool, allowing us to 'hear' the universe. The video emphasizes the potential of gravitational wave astronomy to explore unseen cosmic phenomena and encourages dreaming big for future observatories.
