But we can only place non-zero observational upper linmits on the rest mass
of the photon: It might have a Compton wavelength on the order of 1000 LY, so that c
(the speed which is unchanged by a Lorentz transformation) wouldn't be "the speed of
light". EM fields then wouldn't obey Maxwell's equations but those of Proca. This
wouldn't do the YECs any good though.
