136 - Andrew Strominger: String Theory, Black Holes, and Extra Dimensions

Andrew Strominger is Gwill E. York Professor of Physics and Director of the Center for the Fundamental Laws of Nature at Harvard University, where he works on some of the deepest questions in physics, including black holes and the unification of quantum field theory and general relativity in the form of string theory. In this episode, Robinson and Andy discuss the basics of string theory, including its unifying role in physics, its application to outstanding and once-intractable problems of black holes, and the conceptual difficulties of thinking about higher-dimensional spaces.
