Main Article Content
With reference to primordial black holes, an attempt has been made to develop a practical model of cosmology. Main features of this integrated model are: Eternal role of Planck scale, light speed expansion and rotation of a primordial cosmic black hole, slow thermal cooling, internal acceleration and anisotropy. At any stage of cosmic expansion, there exists a tight correlation between cosmic angular velocity and cosmic temperature. At present cosmic radius seems to be 140.56 times higher than the Hubble radius, angular velocity seems to be 140.56 times smaller than the Hubble parameter and cosmic age seems to be 140.56 times the Hubble age. An attempt is made to estimate galactic dark mass using MOND relation and cosmic angular velocity. Current cosmic graviton wave length seems to be around 4.9 mm. This model is free from ‘big bang’, ‘inflation’, ‘dark energy’, ‘flatness’ and ‘red shift’ issues.
