Density fluctuations in the universe after the recombination period

Letters to the Editor

Abstract

It is shown that the cosmic matter gas after the recombination period can be regarded in a very good approximation as a general relativistic Boltzmann gas in the very vicinity of equilibrium. As a consequence, spatial temperature fluctuations (ΔT/T)≊10−5 imply immense density fluctuations up to (Δp/p)≊105.
