Black Holes and Quantum Weirdness with Janna Levin

1 hour 19 minutes

Black holes get a bad rap. They’ve been cast as the monsters of the cosmos — gobbling up stars and stretching anything that gets too close into cosmic spaghetti. But Black Hole expert Janna Levin has spent her career decoding these mysterious objects, and she thinks they’re just misunderstood. In this episode, she dives into the strange physics of black holes: what they are, what they sound like, what happens if you fall into one, and how there’s a lighter side to every black hole. Janna shares why black holes might not be the end of everything — but the beginning of something even weirder.
