The Cosmological Principle. Viewed on sufficiently large distance scales, there are no preferred directions or preferred places in the Universe. Consequences of the Cosmological Principle. The twin pillars of Cosmology Cosmic homogeneity

The Cosmological Principle. On a large enough scale , the universe is both isotropic and homogeneous ISOTROPY: There is no preferred direction in space. (All directions are alike.)

Cosmological Assumptions. Homogeneity Isotropy Universality Cosmological Principle. Matter is distributed evenly throughout the universe on the largest scales (~ 300 Mpc). The universe looks the same no matter where you are. Again, this is on the largest scales.

Cosmology, lect. 3 Cosmological Principle & Friedmann-Lemaitre Equations. Einstein Field Equation. Cosmological Principle. A crucial aspect of any particular configuration is the geometry of spacetime: because Einstein’s General Relativity is a metric
