The conclusion is that if we smooth the distribution on the largest scales lar ger than several hundred Mpc scales it approaches a homogeneous distribution in accord with th e assumptions that underlie the FRW model However as we go to smaller scale Szydagis. 02.02.2015. 1. /10.

By Jordan . Ilori. . DARK MATTER. Dark matter is a type of matter hypothesized in astronomy and cosmology to account for a large part of the mass that appears to be missing from the universe. Dark matter cannot be seen directly with telescopes; evidently it neither emits nor absorbs light or other electromagnetic radiation at any significant level. Instead, the existence and properties of dark matter are inferred from its gravitational effects on visible matter, radiation, and the large-scale structure of the universe. According to the Planck mission team, and based on the standard model of cosmology, the total mass–energy of the known universe contains 4.9% ordinary matter, 26.8% dark matter and 68.3% dark energy. Thus, dark matter is estimated to constitute 84.5% of the total matter in the universe and 26.8% of the total content of the universe.. Where. are . we. ?. Cosmology. . CMB. P.Natoli. 2009. Planck.
