Volume is a product of x, y and z lengths. In the case of an x-moving photon, there is no length in x. Consequently the volume product vanishes.
Well, you could argue that, way, but it could cause confusion, as there is no specific volume associated with a photon in the first place.
From the 1st post:
... I suppose in this sense, photons could lack volume, but does that mean they lack dimensions? It doesn't appear this could be the case if photons have wavelengths.
The Lorentz transform shows how photons "lack" the forward, x dimension. This could only cause confusion in an idiot's brain.
