Can the Universe Remember? Exploring Gravitational Memory

PBS Space Time explores the outer reaches of space, the craziness of astrophysics, the possibilities of sci-fi, and anything else you can think of beyond Planet Earth. Host Matt O'Dowd breaks down both the basic and incredibly complex sides of space and time.

Can the Universe Remember? Exploring Gravitational Memory

Season 10 Episode 26 | 11m 43s
