[00:00:00]For a century, the cosmos was a silent movie until September 2015 when colliding black holes finally gave the universe a voice. This violent merger, happening over a billion light-years away, sent ripples in space-time racing toward Earth. The LIGO observatories caught this microscopic distortion, confirming a monumental prediction from Albert Einstein and his theory of general relativity. Before this breakthrough, humanity could only study the stars using captured light. Now, we explore the cosmos by actually listening to gravitational waves. The most destructive forces in existence are no longer just distant flashes, but echoing songs waiting to be heard.
