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 is 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?
You can watch the video now, or wait for the Premiere tomorrow:

Fascinating. Could it be possible for things that have no mass to escape from a black hole? If something can exist without mass, how would the near-infinite gravitation of a black hole affect it?
