Our previous publications lead to the fact that the ether elasticity theory in which the ether is shown to be an elastic medium governed by a Navier-Stokes-Durand equation (NSDE), unifies physics theories. The great lines of this unification are the following. Electromagnetism, is the case where the ether is submitted to only densities C of couples of forces associated to the electric charges that creates the field of the displacements of the points of the ether from which one deduces the Maxwell equations and the electromagnetic forces. Electromagnetism is generalized to the case where is also associated to (particles of mass m and electric charge e) submitted to incident fields, by the fact that the Lagrange-Einstein function of a such a yields not only the motion equation, but also, defined by, which is the phase of a wave associated to. This is a solution of a generalized NSDE. A specific sum of waves forms a globule that moves like the and contains all its parameters; reciprocally, a wave is a sum of globules, i.e., of.
