The multiverse. String theory. The God particle. The inflationary Big Bang. Dark matter and dark energy. These are some of the latest theories of physics, but do they say anything about reality? How does someone test to see if there are really trillions of additional universes beyond the boundaries of this one? Or find vibrating strings tucked away in dimensions beyond experience? On this show, Philip Mereton talks with Jim Baggott, the best-selling author of the new book, Farewell to Reality: How Modern Physics Has Betrayed the Search for Truth, about how the authorized version of physics cannot be right and how too many scientific resources are being devoted to pursuing fairy tale physics, and what this all means for the future of science.
