Titled Collective Motion of Moshers at Heavy Metal Concerts, the study analyzes both the disorganized mosh pit (where participants run into each other from all directions) and the relatively organized circle pit (think swirling toilet bowl) or the wal.

The scientists from Cornell's Laboratory of Atomic and Solid State Physics and Department of Physics poured over internet video and studied the participants as "self-propelled agents that experience dissipative collisions." The researchers turned the video into statistical data.

They asked why does a mosh pit that appears to be out of balance actually show characteristics of an otherwise predictable system?
