Randy and Jim explore loop quantum gravity. Loop quantum gravity is a theory of space-time that emphasizes the random, pre-metric connections between points of a reasonably small size (the surface areas are on the order of the square of the Planck length) and the uncertainties therein.

Notes:

1. The papers we read for this program:

- Ashtekar, A., "Introduction to Loop Quantum Gravity." (Lecture). [arXiv]
- Rovelli, C., "Space and Time in Loop Quantum Gravity."
*Philosophy Beyond Spacetime and Beyond Spacetime: Foundations of Quantum Gravity*(2018). [arXiv]

2. Related Episodes of Physics Frontiers:

- Physics Frontiers 30: The Consistent Histories Interpretation of Quantum Mechanics
- Physics Frontiers 35: The String Theory Landscape
- Physics Frontiers 42: Entropic Gravity

4. Carlo Rovelli has a very readable, and so far not too technical, introductory book on Loop Quantum Gravity, cleverly entitled Covariant Loop Quantum Gravity: an elementary introduction to quantum gravity and spinfoam theory. I think this is a pdf, if you want him to continue to live his monkish lifestyle.
