If the reason why (almost?) massless particles must move at the speed of light, is because it's the waveband frequency difference between electrons and protons riding the neutron harmonic, as a (surface) wave-packet. So how neutrinos and other "objects" are fitted into the neutron standing wave, suggests that these are indicative of the "entanglement" superconducting frequencies of "inside" black hole fields, that are integrated into the universe as Quantum Fields. (An impertinent suggestion so one has an intuition to start from) If the observational viewpoint, the frequency-focus of the Quantum Fields is not from a De Sitter space or whatever, then the nomenclature for the identification of the frequency related properties in context, has a different relationship with the observable dimensions of that context. (Some chose to comment on the authority of the proponents of the contents, instead of offering a restaged presentation of the evidence in situ) EM is an effect of the probability occurrence of 1-2-3-4D superposition QM harmonics. (Definitely not Numerology, but it was understandable, back in the day, to speculate...) Ie EM is an integral QM part property of the universe fitted into the p-brane perspective, not generally causal.
