Space-Time as a field of Mass

Although the mass and the electric charge are strictly associated at atomic level, and the fields they generate have the same structure, motion has a different effect on them: while a moving electric charge remains unchanged, but generates a magnetic field, mass changes its value, but does not generate any additional field. This difference should not be substantial, but only formal. (...)

By analysing the omnidirectional propagation of a beam of light, however, we obtain a set of equations which show that motion modifies the space-time by generating a spatial component normal to the motion itself. These equations force us to abandon the traditional concept of space-time as a “container”, however defined, of physical reality and suggests a totally new conception: that of considering the space-time as a field of the mass, coincident with the gravitational field.
