The Biggest Ideas in the Universe is a series of videos where I talk informally about some of the fundamental concepts that help us understand our natural world. Exceedingly casual, not overly polished, and meant for absolutely everybody.
This is the Q&A video for Idea #16, "Gravity." We cover some of the inspiration for general relativity (the Principles of Equivalence and Mach), and do quite a bit more on black holes, including the information-loss puzzle.
