A cosmological model was developed using a quantum equation of state of hidden photon gas, as well as cosmic time. One of the primary objectives of this model is to see if determining the observed rotation speed of galactic matter is possible, without using dark matter DM (halo) as a parameter. To do so, a numerical application of the evolution of variables in accordance with cosmic time and a new state equation was developed to determine precise, realistic values for a number of cosmological parameters, such as energy of the universe U, cosmological constant ?, curvature of space k, energy density, age of the universe etc. The current version of the model partially explains several of the observed phenomena that raise questions since CMB and JWST (VETG, Hubble tension, SMBH).
