The Relativistic Dynamics of Photon Gas Two dynamic equations are established in photon gas, which is just the carrier or medium of electromagnetic waves

The carrier or medium of electromagnetic waves has been vainly searched for many years, and now it has been caught after the establishment of the dynamic equations in photon gas. The photon’s rest mass has been estimated from the cosmic background temperature in space where the photon gas is at an open state of thermal equilibrium, and the photon’s proper magnetic moment is calculated from the dynamic equations of photon gas too. As the carrier of electromagnetic waves, the photon gas is a discrete medium at very high frequency, and then the Bohr’s electron is hardly to emit energy in wave form and can be stably rounding the nuclei in discrete orbits at lower temperature.
