For the first time, scientists have observed ripples in the fabric of space-time called gravitational waves, arriving at the Earth after a violent collision of two black holes 1.3 billion years ago. This confirms a major prediction of Albert Einstein’s 1915 general theory of relativity and opens an unprecedented new window into the cosmos.

Watch an interview with Cleveland Museum of Natural History Executive Director & CEO Dr. Evalyn Gates, an astrophysicist herself, to learn more about this exciting announcement.
