Cumrun Vafa: Puzzles to Unravel the Universe (2020)

Oct 1, 2024

Cumrun Vafa, a Harvard professor specializing in string theory, dives deep into some of the universe's biggest mysteries. He tackles whether string theory can truly be called science, distinguishes between puzzles and mysteries in physics, and shares thoughts on black hole entropy. Vafa discusses the challenges of unifying gravity and quantum mechanics, and intriguingly connects science with ethics and religion. He even reflects on what humanity should preserve for future generations in a hypothetical time capsule. Tune in for a thought-provoking journey!

Is string theory actually science?

Many argue that string theory cannot be proven and should therefore be abandoned. For them, string theory is not science at all. But are they right?

I had the pleasure of discussing this with none other than Cumrun Vafa! Cumrun is a Professor of Mathematics and Natural Philosophy in the Department of Physics at Harvard University, where he has been researching and teaching theoretical physics since 1985. His primary area of research is string theory.

In our interview, we discussed whether we should trust string theory, fine-tuning, and the message he'd put into a billion-year time capsule. We also talked about his book Puzzles to Unravel the Universe.
