I don’t think it is. If there are photons bouncing around in a material it contributes to its mass. Thought it’s an interesting question, does a singular photon traveling through space warp spacetime?
Also photons being defined as massless is the reason they can travel at the speed of light.
We already have racers dying regularly in Isle of Man TT. Blood sports never died, they evolved. Why not sprinkle some steroids over it.
