Is it increasing the number of photons or increasing the energy of each photon? Stochastic inﬂationary theory [3, 4, 5, 6] was developed primarily in order to capture the ef- fects of small scale stress-energy ﬂuctuations (large momenta) onto large scale ﬂuctuations, which On the other hand, a photon fluid is just an electromagnetic field with the well- known definition for its stress- energy- momentum tensor. Photons don't carry charge so the SET of an electric field/magnetic field is not relevant to the photons ( EM radiation) case. ν Gravitation, J.A.
