We report an extended summary of the results presented in the (open access) article in Ref. [1]. The thermal states at the temperature of the cosmic microwave background (CMB) are analyzed and it is shown that the vacuum expectation value of the energy momentum tensor density of photon fields reproduces the energy density and pressure of the CMB. The computations are done in the framework of the Thermo Field Dynamics (TFD). Neutrinos and thermal states at the temperature of the neutrino cosmic background (CNB) are also considered. Consistency with the estimated lower bound of the sum of the active neutrino masses is verified. The fractal self-similar structure of the thermal radiation is also discussed and related to the coherent structure of the thermal vacuum.
