Obviously, this property should be obtained in every
Lorentz frame of reference.
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.
