Therefore, the very principle of mass becomes useless in terms of general relativity.

It never goes to a "different medium".

Mass is not as easy concept as it may seem. Photons don't have rest mass. What makes You think that they do? They do, however, have mass, but we can't call it rest mass, that would be incorrect. Evidently, photons interact with celestial bodies through gravitation. Therefore, they have...

One calculate the kinetic and the potential energies of the particles, knowing their speed it should be simple, then measure the energies of g1 and g2. The difference between the two is the rest mass (of the two particles) E(rest masses)=E(g1)+E(g2)-E(kinetic energies)-E(potential energies)...

When an e-p pair turns into two photons, their rest mass (energy at rest) is given to the photons, as well as the rest of their energy, that is "stored" in the form of kinetic, and potential energy. This comes from the law of energy conservation: E(rest masses)+E(kinetic energies)+E(potential...

I don't know, maybe someone else does.

We know about the ratios you mentioned because we measured them, not because a theory predicts them. "The Higgs", as you call it, is a theoretical effort to explain the mechanisms standing behind the phenomena of particles having mass. In other words, we have a phenomenological description...
