Sean Carroll talks about about his terrific new book, The Biggest Ideas in the Universe: Space, Time, and Motion. He also dives into the importance of equations in popular science writing, conservation, Noether’s Theorem, the mechanics of space, the nature of time, black holes, gravity, and many other topics.

After many years at Caltech, Sean is now at Johns Hopkins University - the Homewood Professor of Natural Philosophy - a joint appointment between physics and philosophy. His research focused on cosmology, field theory, and gravitation, quantum mechanics (origin of probability, emergence of space and time), and statistical mechanics (entropy and the arrow of time, complexity, emergence and causation). He is host of the popular Mindscape podcast.
