Theoretical Physicist Andrew Strominger explains what exactly black holes are and how they could tell us about the beginning of the cosmos.

In this episode, Andrew discusses the questions behind black holes, the strange physics at their event horizon, what they reveal about the nature of space and time, and how he, Stephen Hawking, and Malcolm Perry helped develop the theory that "soft hairs" may store information on black holes' surface. From leading minds like Einstein, Hawking, and Strominger, our understanding of these celestial bodies is constantly evolving, and we still have so much to learn. This one is going to be cool!
