Episode 662: How Do We Know Black Holes Exist? With Dr Paul Sutter

I’d say half the astronomy-related videos on YouTube are all about black holes. Clearly, they’re a fascinating topic, but they’re also a mystery. How do you observe something that can absorb all the radiation and matter falling onto them, and nothing can ever escape? How do we know they’re really there, and what are the best observations we can make?

Today I’m joined by Dr. Paul Sutter, a cosmologist, and astrophysicist to talk about how we know black holes are really there and not just a figment of an astrophysicist’s imagination?
