Here you go, science-folk. This is a very insightful analysis of the physics of mosh pits. Included is a very interesting numerical model generated with repulsion, propulsion, and flocking forces acting on individual particles. The results suggest that the kinematics present in a mosh pit are similar to those of gas particles. Apparently the “random motions over a sufficient time reproduce the statistics of classical gasses via the Central Limit Theorem.”
So, if you ever want to feel like a gas particle in a closed container, go to a heavy metal concert.
