The invisible ripples traveling across the universe at the speed of light
In short: In 2015, humanity detected a cosmic event never seen before: the collision of two massive black holes. This video explores the nature of the vibrations they sent through space.
Amber L. Stuver explains the phenomenon of gravitational waves, which are ripples in the fabric of space. The video details the September 2015 detection by the LIGO detector, where two black holes—each approximately 30 times the mass of our Sun—collided after orbiting one another for millions of years. The event released a vibration that traveled across the universe at the speed of light, providing a new way to witness cosmic destruction.
