Cosmological Principle

(physics and the overall view of things is the same everywhere)

The Cosmological Principle is that the same laws of physics apply throughout the universe, and that if you consider a large enough scale (much larger than Galaxy Clusters (CL)), the universe is similar, the differences being random. E.g., throughout, you find galaxies and galaxy clusters, just different ones.

Technically this means the distribution of matter is homogeneous and Isotropic when viewed on a large enough scale.
