Summary

A fan favorite episode, now with new black hole discoveries! We answer our first listener question, how do black holes work? We talk to Dr. Karl Gebhardt, who has helped discover over half of the black holes that astronomers have ever found. Light cannot escape from a black hole, which means that they are impossible to see. We find out the secret to finding black holes, and how what happens inside might explain mysteries of gravity. Astronomy adventures are ahead in this episode! Music in this episode is by Secret Agent 23 Skidoo from his newest album, Infinity Plus One.
