Abstract: In this paper, we have presented two anisotropic cosmological models, of which the former being T-model is homogeneous and the latter being non T-model is inhomogeneous. We have constructed formula for all the physical and kinematical quantities and established relations among them. Equations of state are constructed. Both these solutions can be applied to all the epochs of the universe for which ξ ϵ [0,1)-{1/2}, where the quantity ξ is a MacCallum parameter and describes the anisotropy of the 4-dimensional space-time. It is explicitly shown that the T-model presented here is more general solution in the sense that it includes the one given by McVitte and Wilt-shire.

Abstract: By highlighting the 12 major shortcomings of modern big bang cosmology and reinterpreting the cosmic redshift as a galactic atomic emission phenomenon, the authors made an attempt to develop a possible model of Black hole cosmology in a constructive way. Its validity can be well confirmed from a combined study of cosmological and microscopic physical phenomena. It can be suggested that, there exists one variable physical quantity in the presently believed atomic and nuclear physical constants and “rate of change” in its magnitude can be considered as a “standard measure” of the present “cosmic rate of expansion”. The characteristic nuclear charge radius, inverse of the Fine structure ratio, the characteristic reduced Planck’s constant seem to increase with cosmic time and there will be no change in the magnitude of Planck's constant. At any cosmic time, ’Hubble length’ can be considered as the gravitational or electromagnetic interaction range. With this idea, independent of the reduced Planck’s constant, inverse of the Fine structure ratio can be fitted in a cosmological approach. At any cosmic time, the product of ‘critical density’ and ‘Hubble volume’ gives a characteristic cosmic mass and it can be called as the ‘Hubble mass’. Schwarzschild radius of the ‘Hubble mass’ again matches with the ‘Hubble length’. Most of the cosmologists believe that this is merely a coincidence. Here the authors emphasize the fact that this coincidence is having deep connection with cosmic geometry and the cosmological and microscopic physical phenomena. In this model, forever rotating at light speed, high temperature and high angular velocity small sized primordial cosmic black hole of mass gradually transforms into a low temperature and low angular velocity large sized massive primordial cosmic black hole.
