In most cosmological models, matter is considered to be distributed with homogeneity and isotropy .The density of matter is the same every where. But in the real universe matter is concentrated within galaxies and cluster of galaxies. In the present work we explore the possibility of the formation of condensation in some cosmological models built using different field theories. In particular, the self-consistent model [1] formulated in the context of the Generalized Field Theory [2], the standard model built in the General Theory of Relativity, and Saez and de Juan model [3] constructed in the background of Moller Tetrad Theory of gravitation [4], are used in this study. A comparison between the results obtained in each case is given. [1] Wanas, M.I. (1989) Astrophys. Space Sci. 154, 165. [2] Mikhail, F.I. and Wanas, M.I.(1977) Proc. Roy. Soc. London A356, 471.
