If the flight of a proton is a photon; a sustained flight that does not obey Lenz's Law (in effect the law of conservation of energy), then there can be two other positive particle radiations corresponding to positive temperature particles and positive gravitational particles.
Both are types of photons. But, to accelerate positive particles to light speed would suggest that they are mass-less. This is consistent with the derivation for force density, where a negative force density requires that the particle has some mass, and at the same time, positive particles have no mass.
Mass, mm, as the multiplicative constant to obtain weight, wtwt, under gravity gg,
wt=mgwt=mg
is fully determined and only determined by the presence of gravity particles.
At this point we extend our definition for mass to include charge mass, meme inertia of a particle accelerated under the electric force and temperature mass, mTmT inertia of a particle accelerated under the temperature field. Mass, mm is redefined as mGmG, the gravitational mass/inertia in acceleration under gravity.
An electron then has meme but not mGmG nor mTmT. Electrons do not fall under gravity! Neither do temperature particles fall under gravity.
