$$ BEFORE the GR-coup (after Einstein died ~1954-55?), that was TRUE.
$$ SiNCE the GR-coup THAT isN'T TRUE ..Since THEN the m isN'T= E/c^2.
$$ ALSO the following equation has no ANGULAR momentum or LaGrangian,

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).

$$ [Pa*Vol. = n*k*T]
$$ [Pascal*Vol. = n*k*Temp.]
$$ [Pressure*Volume = n*k*degreeKelvin,] ..
$$ [..note the EARth's AMBiENT photon gas PARTiTiON function k].
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].

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

And you're full of the stuff that produces gas.
