Steve and Corey talk with theoretical physicist Raman Sundrum. They discuss the last 30 years in fundamental physics, and look toward the next. Raman argues that Physics is a marketplace of ideas. While many theories did not stand the test of time, they represented avenues that needed to be explored. Corey expresses skepticism about the possibility of answering questions such as why the laws of physics have the form they do. Raman and Steve argue that attempts to answer such questions have led to great advances. Topics: models and experiments, Naturalness, the anthropic principle, dark matter and energy, and imagination.
