About this episode
John has launched a new podcast project with Katie Mack! Crash Course Pods: The Universe is a new limited series podcast where Dr. Katie Mack, a theoretical astrophysicist, walks John Green through the history of the entire universe - including the parts that haven’t been written yet. Join John and Katie as they discuss the Big Bang, cosmic dawn, black holes, and, eventually, the end of our universe. It’s available now on at https://youtube.com/CrashCourse and wherever podcasts are available. If you're in need of dubious advice, email us at hankandjohn@gmail.com.
