The idea that the universe is made of tiny vibrating strings was once the science theory du jour. String theory promised to unite the disparate theories describing particles and gravity, and many people, not just scientists, were optimistic that a theory of everything might be within our grasp. But here we are, many years later, and string theory doesn’t seem to have delivered on its initial promise. What happened? We consider the science around string theory in this episode of Skeptic Check.

Guest:

Brian Greene – Physicist and mathematician at Columbia University, and author of The Elegant Universe: Superstrings, Hidden Dimensions, and the Quest for the Ultimate Theory.
