Abstract
The stochastic component in density inhomogeneities of cosmic matter can cause the intensity scintillation of sources at cosmological distance. This scintillation effect is one of the origins of small angular anisotropy in the microwave background. That is, the density inhomogeneities in the epoch after the recombination would also contribute to the formation of background anisotropy. Therefore, an upper limit for the density inhomogeneities of cosmic matter can be obtained by the observation of small angular anistropy of background radiation. The result is that, if the universe is closed, a strong inhomogeneity has never been evolved in the distribution of total density (including visible and invisible matter), namely, even at the present the total density distribution might still be rather homogeneous.
