Abstract

A non-conventional approach is developed and used to find the primordial angular gradient, anisotropy, of the temperature of the Cosmic Microwave Background Radiation (CMBR), as well as the density fluctuations in an adiabatic expanding universe. The obtained results is a consequence of considering the magnitude of the angular gradient of the temperature of the CMBR as a constant function with respect to the proper time of the spatially perturbed FRW expanding universe.
