Formation of Condensations in an Expanding World Model
The problem of forming inhomogeneities in an expanding world model is investigated. The world model used has been obtained  as a unique solution of the unperturbed field equations of the generalized field theory . This model is free from particle horizons, and has the parameters (k=−l, Ωo =0.75, qo =0) The geometric structure used to construct this model is an absolute parallelism space .
The solution of the perturbed equations shows how condensations are formed in the model. The behaviour of matter in the model depends on its distance from the centre of perturbation. It is shown that at a certain distance S = Se from the centre, matter is stationary. If S > Se matter recedes away from the centre, while if S <Se matter falls towards the centre of perturbation. This may throw some light on the way of forming galaxies and clusters of galaxies in the Universe.
