In this paper the experimentally verified Stephan Boltzmann Law and Planks law are used to calculate the Cosmic Microwave Background or CMB radiation received on earth in all directions from the sky. This radiation from SUN, planets, asteroids, stars, interstellar dust and Galaxies is in Microwave range covering all the frequencies including the K, Ka, Q, V and W bands as measured in WMAP mission. This method explains theoretically about the origin, propagation uniformity of CMB in our universe. The reasons for this amazing theoretical uniformity are many. One of the reasons is the uniformity of stars and Galaxies in all most all directions in the sky. Another reason is the averaging done by main lobe of dish antenna for few degrees around the main direction, which is a measuring instrument sensor of WMAP satellite. In addition, the side lobe pickup of bright sources in the sky also adds to the problem, which depends on the three-dimensional gain pattern of the dish. Additional analysis is done, which results into large angle multipole-l systematic errors. It is found that NO additional Bigbang generated Microwave background radiation was there after excluding radiation from Stars and Galaxies in these WMAP CMB measurements.
