We test the cosmological principle by fitting a dipolar modulation of distance modulus and searching for an evolution of this modulation with respect to cosmological redshift. The Anthropic Cosmological Principle is an extension of the The Copernican Cosmological Principle and is that not only on a large scale, the universe is both homogeneous and isotropic (in 3-D space) but also that by our very being here, we are viewing "our universe" at a "priveledged" location in spacetime Rationale/Implications The Solution of the Problem of Gravitation on the Basis of the General Principle of Relativity Part III: Considerations on the Universe as a Whole 30.
