Does Standard Cosmology Express Cosmological Principle Faithfully?

General Relativity and Quantum Cosmology 2007-05-23 v3

Abstract

In 1+1 dimensional case, Einstein equation cannot give us any information on the evolution of the universe because the Einstein tensor of the system is identically zero. We study such a 1+1 dimensional cosmology and find the metric of it according to cosmological principle and special relativity, but the results contradict the usual expression of cosmological principle of standard cosmology. So we doubt in 1+3 dimensional case, cosmological principle is expressed faithfully by standard cosmology.

physical interpretation changes, but mathematica formula keeps
