Quantum theory of mass
The mass consists of a multiple of the elementary mass, that would set up a quantum theory of the mass. The elemental composition is simple: elementary quantum of action h * t (p) divided by c. According to Wikipedia in this calculation comes to m(p) = 2.17644 · 10 ^ -8 kg. This is the mass of a quantum or a photon, which is really moved with the highest real speed. But that may actually not be, then every place has a minimum density of what would be in areas of black holes according to the world formula. So what's wrong is h or elementary length and elementary time. Do I have to come good to continue working, but we're now at CERN in masses, which are well below the Planck mass, although this should be by definition the smallest, so the question of elementary mass is not solved yet.
The mass proportionalities
The photon, which travels at the speed of light, has the elementary mass. This is because the travel speed v and mass are inversely proportional. A black hole is rotating at the speed of light, it has the highest, namely the infinite mass, but can not move forward because all the velocity potential is used up for the rotation. A photon is rotating, however minimally, because it uses almost all of the potential speed for paste.
v (rotating) ~ m

v (forward) !~ m
