$$ BEFORE the GR-coup (after Einstein died ~1954-55?), that was TRUE.
$$ SiNCE the GR-coup THAT isN'T TRUE ..Since THEN the m isN'T= E/c^2.

Hamiltonian ENTHALPY E = eM + L + eV
                = REST mass + LaGrangian, L + Volt*Amp*sec, eV
                    = m*c^2 + h*fL + nA*hbar*fA
                    = m*c^2 + pL*c + pA*fA
Where..
pL = LiNEAR momentum  ; pA = ANGULAR momentum.
fL = LiNEAR frequency ; fA = ANGULAR frequency.
eK = LaGrangian+eV = E-eM = E-eF-L = KiNETiC energy.
eV = E-eM-L = eG-eM = eF+eK-eM = eK-L, ..OR= -(m1*v1^2/2).

Note, k in nkT is Boltzmann's, Pauli's & Bose/Einstein's PARTiTiON k.
[i.e. THAT's "Bose" ..as in BOSON or boson, as in PHOTON GAS, duh.!!]
i.e. THAT equation is NOT LiMiTED for any established EARth ALTiTUDE.

You're so ANTi-Brian sometimes, Bilge. MORE ANTi-Brian; BiGGER loser.

$$ There're lots of k's ..you COULD have been a little more specific.

$$                 Space is full of photon gas.
 Photons can be said to have a LONGiTUDiNAL polarization in the SAME
 sense YOUR "not reachable" POiNCARE element is not accepted science.
 Technically, a photon can only be seen by looking directly UPstream.
 [i.e. So, clearly, in that sense, the photon is LiNEARLY polarized].

$$ Hope this helps,                                         ```Brian.

Re: is there a "theoretical" mass for a photon ???
