Macro-Scale Circles and Cycles

The circle, the sphere and the cycle are everywhere in life, everywhere on earth, everywhere in the universe. The pictures below show enormous circle forms. Together they show the power of the circle form in the universe. At this astronomical scale, gravity is the force that creates these forms.

Human-Scale Circles and Cycles
