Atoms have a stochastic opportunity to biggen or to smallen. To every biggening, there is always an opposed smallening. An object that biggens tends to stay biggened, and an object that smallens tends to stay smallened. When atoms aggregate to one entity, they disperse and flee in another. This consequential action can occur in two entities irrespective of their relative location. If an animal species collectively biggened, a heavily populated city could smallen.
