Leonard Susskind is Felix Block Professor of Physics at Stanford University. Along with other accomplishments, he is among the fathers of such revolutionary concepts in physics as string theory, black hole complementarity, the holographic principle, and the string-theoretic landscape. He was also the guest on episode #217, where he and Robinson discussed the fine-tuning problem and the physics of the multiverse. In this episode, Leonard and Robinson get into another topic—black holes and the information paradox. More particularly, they talk about important figures like Stephen Hawking and Gerard ’t Hooft, singularities, chaos, whether the cosmos is a hologram, the end of the universe, and more. For further details, check out Leonard’s book on the title: The Black Hole War (Back Bay Books, 2009).
