“…The latter are particularly attractive, since they imply the conservation of the invariant momentum squared, which is associated with mass. Interestingly, it is found that the deviations from usual geodesics increase with decreasing mass [27,33]. However, the transition to zero mass is not continuous.…”

The motion of spinning massless particles in gravitationally curved backgrounds is revisited by considering new types of constraints. Those constraints guarantee zero mass (PµP µ = 0) and they allow for the possibility of trajectories which are not simply null geodesics. To exemplify this previously unknown possibility, the equations of motion are solved for radial motion in Schwarzschild background. It is found that the particle experiences a spin-induced energy shift, which is proportional to the Hawking temperature of the black hole background. 2

“…Despite the death and lack of solid experimental proof [1]- [4], it is generally agreed (perhaps believed) that photons have no mass. Though this notion of a zero-mass photon has been questioned over the years [5]- [9], this deeply entrenched notion has been deduced from the logical fusion of two (seemingly) immutable facts of experience so well supported by experimental evidence.…”

Are Photons Massless or Massive?

Prevailing and conventional wisdom as drawn from both Professor Albert Einstein's Special Theory of Relativity (STR) and our palatable experience, holds that photons are massless particles and that, every particle that travels at the speed of light must-accordingly, be massless. Amongst other important but now resolved problems in physics, this assumption led to the Neutrino Mass Problem-namely, "Do neutrinos have mass?" Neutrinos appear very strongly to travel at the speed of light and according to the afore-stated, they must be massless. Massless neutrinos have a problem in that one is unable to explain the phenomenon of neutrino oscillations because this requires massive neutrinos. Experiments appear to strongly suggest that indeed, neutrinos most certainly are massive particles. While this solves the problem of neutrino oscillation, it directly leads to another problem, namely that of "How can a massive particle travel at the speed of light? Is not this speed a preserve and prerogative of only massless particles?" We argue herein that in principle, it is possible for massive particles to travel at the speed of light. In presenting the present letter, our hope is that this may aid or contribute significantly in solving the said problem of "How can massive particles travel at the speed of light?"

“…Of particular interest in the present reading is the source coupled Equation (1), and not not (3) and as such, we shall not-after the present section-come back to this Equation (3). From these two tensor Equations (1) and (3), we can write down the four Maxwell's equations which we are used to, and, much readily identify with, i.e. :…”

“…Despite the inconclusive experimental evidence (see e.g., Refs. [1]- [10]), photons are largely believed to be massless and the most compelling of all evidence there-it is said-is found in their physical and natural manifestation as long ranged and long lived particles (e.g., Refs. [11]- [13]).…”

It is largely believed (or strongly assumed) that photons are massless particles and the most compelling evidence there-it is said-is found in the manifestations of photons being long ranged and long lived particles. As we have done before, albeit, with a much better and clear insight in the present than before; we argue herein that massive photons can still enjoy the special and rare privilege of travelling at the speed of light c while being long ranged, long lived and most of all, obeying the much desired gauge symmetry. This we achieve by breaking the traditional Lorenz gauge and in its place, we introduce a new Special Gauge Condition (SGC) that does the work of assuring the photon its longevity, long range-ness and that it [photon] propagates at the speed c. However, the most melancholic outcome of our investigation is that if the present scheme is what subtle Nature has chosen to endow the photon a non-zero mass so that it [photon] still obeys gauge invariance, is long ranged, long lived and travels at the sacred speed c; then, this non-zero photon mass may be very difficult, if not impossible to measure. We use the equations developed to investigate Lorentz violation in γ-ray bursts.
