Abstract
At any stage of cosmic evolution, from the Planck scale to the scale of the universe at present, 1) The relations, (GMt / c2)≅ Rt ≅ (c/Ht), can be integrated into quantum cosmology. 2) Considering continuous light speed expansion of the cosmic horizon, the special theory of relativity can be successfully implemented into a flat space cosmology model and cosmic inflation and cosmic acceleration models can both be relinquished. 3) Considering the ratio of gravitational self-energy density and thermal energy density to be 
(where Tpl is the Planck scale temperature and Tt is cosmic temperature at any time), quantum gravity can be implemented in low energy scale current cosmological observations. In addition, the currently believed dark matter energy density and visible matter energy density can be accurately related with the ratio of gravitational self-energy density and thermal energy density.
Keywords: Planck scale, cosmology, light speed expansion, cosmic gravitational self-energy density, cosmic thermal energy density, dark matter density, visible matter density, quantum gravity, dark energy.
