222 | Andrew Strominger on Quantum Gravity and the Real World

Quantum gravity research is inspired by experiment — all of the experimental data that supports quantum mechanics, and supports general relativity — but it's only inspiration, not detailed guidance. So it's easy to "do research on quantum gravity" and get lost in a world of toy models and mathematical abstraction. Today's guest, Andrew Strominger, is a leading researcher in string theory and quantum gravity, and one who has always kept his eyes on the prize: connecting to the real world. We talk about the development of string theory, the puzzle of a positive cosmological constant, and how black holes and string theory can teach us about each other.
