$$ The Coup-GR has reverted back to the PRE-Einstein definition.
$$ Where Einstein says, E=m*c^2; Coup-GR says, SAME m NOT=E/c^2.
$$ "Mass" is NOT ALSO "inertia" AND "momentum", as Coup-GR says.
$$ [And, the historical definition of "mass" is SI "kilograms"].
Re: SI Giorgi MKSA SYSTEM "kilogram", the STANDARD MODEL "mass".
Re: Coup-GR mass is NOT=E/c^2, if E=m*c^2 ..since Einstein died.
Re: QED is numerology ..that is without GUESS iSS as a STANDARD.
Re: PHOTON MASS -- A FACT. MASSLESS PARTiCLES -- NOT FACT. END.

Generally speaking, it's the theory that tells you what mass, or
anything else in the theory, is. So, one cannot ever provide any such
"proof." One theory's mass can be another theory's energy. One theory's
distance can be another theory's converted time.
All you can ask of a theory is if its operational definitions of its
variables are mutually consistent and consistent with measurement.
