Abstract:
The small angular anisotropy of the microwave background may be caused by the gravitational scintillation due to the stochastic density perturbation in the course of propagation after the recombination epock. The observed anisotropy limit would suggest that the total density perturbation with seze of ∼10 Mpc is still in a linear regime.
