Jim and Randy discuss a cosmological theory that purports to find an explanation for the arrow of time in gravitational theory based on the shape and distribution of matter and how it evolves.



1. The paper we read for this program: Identification of a Gravitational Arrow of Time by Barbour, Kowslowski, and Mercati.

2. Mentioned in this episode: The Physical Basis for the Arrow of Time by H. Dieter Zeh.

3. Mentioned in this episode: Gravity From the Ground Up, B. Shutz.

4. [Update] It came to me in the shower: the word I was looking for is "eschatological."

5. Our subreddit.
