Abstract
The consequence of a perturbation in the expanding universe is investigated. It is found that the density gradient decreases with time, while the ratio between the perturbed density and the background density diverges more and more from unity. These results are essentially in agreement with observation and explain why even in "point source" cosmologic models, condensations of extremely high densities are not to be expected at present.
