Episode notes

In anti-decider space, if you fix a moment of time and start moving off in space, eventually you'll come back right to where you are. In space, it has a boundary in time at the infinite future. If we try to invoke the holographic principle that the holographic plate lives at the boundary, the boundary has no time. It's not over till the fail 86. We don't know what the final thing is going to look like. But I think the basic problem that people have wrestled with,. the problem you say is a very vexing one, but it's not the only vexing one. How do we put all these things? It's just

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.
