Abstract: 

Equation which is a differential equation in R(t) and t represents the basic relationship with which the cosmological models can be constructed. The parameters E and Ù vare arbitrary each of which may be positive, zero or negative independently of the other. The nature of the models is determined by the actual relationships that hold between R(t) and t which again are dependent on the choice of the values of E and Ù. All the models obtained from Eq. have, however, one feature in common: they all just represent the dynamical picture of the Universe in the classical sense. This is inherent in Eq. which does not contain c, the speed of light, as an entity. But since all our knowledge about the structure and dynamics of the Universe are obtained from light signals, the inclusion of cist relevant in any comprehensive, mathematical formulation of the World models

Key Words: Frame of References, Speed of Light, Cosmology, Contracation, Gravitational Collapse.
