Such a model, however, could violate a widely held tenant of cosmology known as the Copernican principle.
This theory states that the universe is homogenous—when viewed on a very large scale, different parts of the universe look essentially the same.
The Copernican principle is a built-in assumption of the current favored solutions to Einstein's equations, called the Friedmann-Robertson-Walker space-times.
Hmmm... This sounds dubious. I like the homogeneity assumption. Occam's Razor, and all that jazz.
