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 associated with Idea #20, "Entropy and Information." We fill in some of the properties of entropy, then connect it to more speculative ideas about cosmology, spacetime, and Boltzmann Brains.
