Gravitational Waves Discovered for the First Time!

The video explores the groundbreaking detection of gravitational waves, a concept first proposed by Einstein over a century ago. It explains how LIGO, the Laser Interferometer Gravitational Wave Observatory, was instrumental in detecting these waves from a black hole collision in 2015. The video delves into the workings of LIGO, highlighting its sensitivity and the challenges faced in isolating true signals. The detection of gravitational waves opens a new window into the universe, allowing us to study extreme cosmic events and advancing technology in fields like cryogenics and optics. The video emphasizes the importance of curiosity-driven science and the broader implications of understanding the universe.
