Vacuum frame theory

In this connection it should finally be mentioned that Comay [63] and Hunter [64] have discussed the field concept by Evans and Vigier on the basis of conventional electromagnetic theory where the 4-current of Eq. (22) vanishes in the vacuum. Their analysis leads to the obvious conclusion that the field vanishes in such a case. This does, however, not rule out the existence of B(3) when there is a nonzero 4-current of the type (26) introduced by de Broglie, Vigier and Evans. Thus, without a Proca-type equation (22), no steady-state magnetic spin field can exist in a rest frame K. ... 

Let us picture the vacuum as a fluid filling the preferred frame 2. As usual in electromagnetic theory, any material substance is described by three parameters [62, Chap. I] 3... 

The special theory of relativity builds on the idea that the laws of physics should be the same in all frames of reference that move relative to each other on straight trajectories with constant velocity, i.e., in unaccelerated motion. The second building block of the theory is the postulate that the velocity of light in the vacuum c is a fundamental constant and thus the same in all such inertial frames. The quantities defined in one inertial system are readily calculated in a different frame of reference by making use of a special prescription that states how time and space coordinates should change such that this postulate is satisfied the Lorentz transformation.
