The hierarchy of bodies in space

Bodies of the same size suspended uniformly in space constitute a system in a state of uniform volumetric tension because of mass-to-mass forces of attraction.

This new paper  shows that such a system “snaps” hierarchically, and evolves faster to a state of reduced tension when the bodies coalesce hierarchically, into few large and many small bodies suspended in the same space.

Hierarchy, not uniformity, is the design that emerges, and it is in accord with the constructal law.
