Abstract:
    In this course of presentation, we will consider the rotational perturbation of the Robertson-Walker universe will be examined in order to substantiate the possibility of the existence of Massive scalar field. We will study, the exact solutions for metric rotation Ω( r,t ) and the matter rotation w ( r,t ) under different conditions, and also study their nature and role from different angles.
Keywords:
    Massive Scalar, Non Rotational Universe, Rotational Universe
