The So-Called Speed of Light Is Not the Speed of Light - A No-Go on Speed-Talk for the Null Case

This paper states a narrow interpretive no-go concerning the phrase “speed of light.” The constant ccc remains fully intact as the invariant constant appearing in relativity, electromagnetism, and quantum field theory. The paper denies only the literal ontological reading of ccc as a speed owned by a photon-object. The argument is that speed-talk requires a subject, a frame, a time parameter, and a rate of position-change assigned in that frame. In the photon case, the relevant ontology fails: the photon has null proper time, no rest frame, and no licensed intermediate spacetime history. A frame-assigned value ccc remains operationally valid, but it does not become a kinematic property owned by a photon traveler. The paper therefore concludes that the so-called speed of light is not the speed of light in the literal ontological sense. It is operational shorthand for the invariant constant ccc, not a photon-owned speed. The proposal is interpretive only and introduces no new equations, observables, or empirical predictions.
