Gravitation, Relativistic Quantum Mechanics

The gravitation potential is considered as a four potential like the electromagnetic one.

Gravitation is derived from four rest mass current density with new field equations.

Starting from a model and linear wave equation for a massless and spinless particle, the gravon, a model for the free photon and its spin is developed. It interacts with the Dirac electron in the common way only through the respective spins. From that a model for a massless neutrino is developed which exhibits as such the parity violation and the neutrino flavours. With the neutrino flavours neutrino oscillations are derived.
