If gravity particles are particles that give us weight,
we are in serious trouble with our definition of mass based on gravity (circular momentum in a magnetic field is different). These particle are in pairs, one type acting opposite to the other. One impart gravity potential, makes an object lighter; the other impart opposite potential energy (negative), makes the object heavier.
If such particles can be introduced and remove from a body, like colored photons, temperature particles and charge particles, objects can be made lighter or heavier by introducing such gravity particles, which might be misinterpreted as changes in mass. In particular, isotopes; when a particle carrying negative gravitational potential is ejected from the nucleus, the nucleus is seen to have gain in mass, although it is its gravitational potential that increased. When a particle carrying positive gravitational potential is ejected from the nucleus, the nucleus is seen to have loss mass, although it is its gravitational potential that decreased. The ejected particles when stopped as the result of collisions, release their component energy as heat (energy oscillating in \(t_T\) or charge potential (energy oscillating in \(t_c\)). This could be radioactivity that Madame Curie first discovered. The changes in mass as radioactive isotopes decay can be re-interpreted as residing particles being ejected from the nucleus.
The gravity particle carrying positive gravitational potential energy can be injected around a nucleus to make them more massive. The nucleus is now a heavy isotope. When such gravity particles are subsequently ejected, the nucleus's mass decreases, and the packet of energy released can be detected upon collisions as heat or charge potential. And so, a body can be made radioactive by injecting positive gravity particles.
It is possible that the negative gravitational particles provides the gravitational attraction at the nucleus that binds the nucleus together. When one such particle is ejected, the nucleus breaks apart, in particular an alpha particle can break away from the nucleus. Positive gravity particles orbit around the negative gravity particles at the nucleus. When positive gravity particles are ejected, the nucleus is seen to have loss apparent mass, likely in the form of a neutron decay to a proton. When negative gravity particles are ejected, the nucleus is seen to have gain apparent mass, likely in the form of a proton decay to a neutron. In both cases energy are expelled, irregardless of the apparent opposite change in mass (gain mass vs loss mass).
Without experimental proof, we should also inject a pinch of salt. But still, Higgs Boson, my left foot, gravity particles more likely.
Gravity particles provide for the attraction force that forms the nucleus and account for charge, energy and mass changes in radioactive decays. In fact the emission and absorption of gravity particles are the cause of radioactivity.
