Is time travel possible? What does it mean to say the universe is fine-tuned? Could our universe be fake? Or, if it is real, is it part of a multiverse? In an attempt to solve such mysteries, leading experts attempt to break the world down to its smallest particles and build it back up--to understand the universe by understanding the atom. In this compelling course, Dr. Robert Lawrence Kuhn, creator and host of the hit PBS series Closer to Truth, examines the riddles of the universe with thirteen luminaries in physics, cosmology, astronomy, philosophy, mathematics, and chemistry. Kuhn's interlocutors include three Nobel laureates: University of California, San Francisco physics professor David Gross, recognized for his contributions to particle physics and string theory; Massachusetts Institute of Technology physics professor Frank Wilczek, celebrated for his research in fundamental particle physics, cosmology, and the physics of materials; and Saul Perlmutter, head of the Supernova Cosmology Project at Lawrence Berkeley National Laboratory. You'll learn a great deal from Kuhn's interviewees, but you'll also join them in marveling at what remains unknown. For, as Kuhn says, "the more we comprehend, the greater the mystery."
