Host: Chris Mooney

Our guest this week is Sean Carroll—theoretical physicist at CalTech, and skilled science communicator.

I've known Sean and his work for almost a decade, and I've invited him on to talk about his latest book: The Particle at the End of the Universe: How the Higgs Boson Leads Us to the Edge of a New World.

Sean Carroll is a physicist at the California Institute of Technology. His research focuses on theoretical physics and cosmology, especially the origin and constituents of the universe. He has contributed to models of interactions between dark matter, dark energy, and ordinary matter; alternative theories of gravity; and violations of fundamental symmetries. Carroll is also the author of From Eternity to Here: The Quest for the Ultimate Theory of Time. He has appeared on TV shows such as The Colbert Report and Through the Wormhole with Morgan Freeman, and frequently serves as a science consultant for film and television. He blogs at Preposterous Universe.
