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.

Andrew Strominger received his Ph.D. in physics from the Massachusetts Institute of Technology. He is currently the Gwill E. York Professor of Physics at Harvard University. Among his awards are the Dirac Medal, the Klein Medal, the Breakthrough Prize in Fundamental Physics, and a Guggenheim Fellowship.

Einstein's general theory of relativity, plus some reasonable assumptions about the universe and what it's made of, has a remarkable implication: that as we trace cosmic evolution into the far past, w...

Every time you see an apple spontaneously break away from a tree, it falls downward. You therefore claim that there is a law of physics: apples fall downward from trees. But how can you really know? A...
