The Booda cosmic isotropy duality hypothesis states: 1. Construct a spherical shell in spacetime. Mass-energy without and mass-energy within move overall to preserve their dual isotropic projection upon the shell, including position and apparent spin. 2. This hypothesis involves all entities in spacetime from vacuum quanta to the background radiation. 3. The shell may be representative to that of an observer or object, and eventually generalized to any 2-D manifold. Is the hypothesis provable?
