WebJul 2, 2010 · Assuming that the relativistic universe is homogeneous and isotropic, we can unambiguously determine its model and physical properties, which correspond with the … The cosmological principle implies that at a sufficiently large scale, the universe is homogeneous. Based on N-body simulations in a ΛCDM universe, Yadav and his colleagues showed that the spatial distribution of galaxies is statistically homogeneous if averaged over scales of 260 / h Mpc or more. [18] See more In modern physical cosmology, the cosmological principle is the notion that the spatial distribution of matter in the universe is homogeneous and isotropic when viewed on a large enough scale, since the forces are … See more Since the 1990s, observations have shown that, if one assumes the cosmological principle, then around 68% of the mass–energy … See more Karl Popper criticized the cosmological principle on the grounds that it makes "our lack of knowledge a principle of knowing something". He summarized his position as: See more Astronomer William Keel explains: The cosmological principle is usually stated formally as 'Viewed on a sufficiently large scale, the properties of the universe are the same for all … See more The cosmological principle is first clearly asserted in the Philosophiæ Naturalis Principia Mathematica (1687) of Isaac Newton. … See more Although the universe is inhomogeneous at smaller scales, according to the ΛCDM model it ought to be isotropic and statistically … See more As stated above, it is true that the cosmic microwave background provides a snapshot of an isotropic and homogeneous universe. Nevertheless, what is often not advertised is that there is a dipole anisotropy in the cosmic microwave background See more

Fred Hoyle, Thomas Gold and Hermann Bondi developed this model in 1948. This accepts the expansion of the universe and the theory of relativity, but the suggestion of constant matter creation keeps the universe in a steady state. chiss planet
