Formation of the initial distribution of matter inhomogeneities in the era of radiation domination

This paper considers the dependence of the Universe expansion rate in the era of radiation domination of the orbital angular momentum of photons filling the Universe. It is shown that the presence of a nonzero orbital angular momentum in photons leads to increase in the rate of expansion. As a consequence, the hypothesis is made that areas of the Universe, having photons with nonzero orbital angular momentum inside them, will cool faster. In these areas the elementary particles will form earlier, compared to the rest of the Universe. Therefore, these areas become the future centers of the primary material inhomogeneity.
