Cool: how economic "energy" and gravitational energy are similar, and negative
energy leads to collapse!
This may seem odd, but recall Seth wrote the book "Programming the Universe",
how the universe is a calculation, so to speak, thus its not too great a
stretch to see the connection.
Abstract: Because gravitational energy is negative, self-gravitating
systems are susceptible to runaway instabilities such as gravitational
collapse. Financial systems also possess a kind of negative "energy" in the
form of debt. This talk presents a simple statistical mechanical model of how
energy/money distributes itself through a set of coupled systems that allow
negative energy or debt. The model identifies a phase transition from positive
to negative specific heat: when gravitational or financial systems pas through
this phase transition, they become unstable. I identify the mathematical
conditions that give rise both to bankruptcy and to black holes.
