In a heuristic approach, with reference to ‘conservation of energy’, ‘light speed expansion’, ‘light speed rotation’, ‘Kerr-Schwarzschild radius’, ‘constancy of centripetal force’, ‘Planck scale’ and ‘quantum gravity’, we introduce a heuristic ‘toy model of cosmology’. The authors would like to stress the fact that, ‘with light speed expansion and light speed rotation’ qualitatively ‘Hubble parameter’ and ‘angular velocity’ both can be shown to be secondary physical constants and their individual roles can be shown to be similar. With four unified, simplified and workable assumptions, a number of useful cosmological formulae can be generated and the current Hubble parameter and current microwave back ground temperature can be fitted accurately. With the proposed assumptions: 1) The intended purpose of ‘lambda’ term can be understood and in future it can be relinquished. 2) Cosmic acceleration and dark energy concepts can be relinquished at fundamental level. 3) Cosmic flatness can be well understood. 4) Comic ‘horizon problem’ can be eliminated at fundamental level. In future, either from ‘academic interest’ point of view or from ‘serious research’ point of view, this toy model can be recommended for in depth analysis at fundamental level.
