Obviously, this property should be obtained in every Lorentz frame
Furthermore, it can be argued that the constancy of the speed of light c from Lorentz frame
to Lorentz frame
, which can be deduced from the resulting Lorentz transformation, is due to the presence of the PV in the photon's line of travel.
From (11) the previous paragraph shows that the cutoff wavenumber [k.sub.c*] in (8) and (9) is associated with the mode counting in (10) taking place within the invisible PV Since the number of these PV modes is not influenced by the free-space Lorentz frame
observing the QV, the [k.sub.c*] in (8) and (9) must be independent of the Lorentz frame
"In any and every local Lorentz frame
, anywhere and anytime in the universe, all the (Nongravitational) laws of physics must take on their familiar special-relativistic form.
