Who discovered the Unified Field Equation
Excerpt taken from "Jacobson Resonance: Inertial Electromagnetic Induction"
Only if space and matter represent one unified conformation (an absolute continuum) can a purely mechanical model explain universal causation, devoid of actions-at-a-distance. And, only therefrom may one eliminate the niggling problems associated with field theories. In our ordinary experience of daily life, we view the causal nexus of natural phenomena as a result of communication of motion through touch, push or pull, combustion by heating…etc. However, atoms are mostly space, and atoms interact across extensions of space.
During the first half of the nineteenth-century, it appeared beyond question that light could be interpreted as a vibratory process in an elastic inert medium filling universal space. It appeared necessarily consequential due to the fact that light is capable of polarization, and this medium (the ether) must possess the nature of a solid body; because transverse waves were not thought to be possible in a fluid. The phenomenon of aberration favored this notion of a quesi-rigid ether. For Maxwell, this ether had properties of a purely mechanical nature, although said properties were complicated. Yet, Maxwell could not yield a satisfactory mechanical interpretation of his laws for electromagnetic field. Physicists became accustomed to admitting electric and magnetic forces as fundamental concepts side by side with mechanics, without requiring a mechanical interpretation. For Hertz, the ether also appeared as bearer of electromagnetic fields. The duality was evident, as physicists thought the ether had a definitely assigned velocity throughout the whole of space, i.e. matter subsisted in space.
This was at variance with experiments on the propagation of light in moving fluids. Then, Lorentz took from ether its mechanical properties and took from matter its electromagnetic qualities. Lorentz succeeded in reducing electromagnetic interactions with Maxwell’s equations for free space. Immobility was the only property left to the ether by Lorentz, whereas special relativity left the ether with no mechanical properties. Yet, Einstein admitted that the special theory of relativity did not compel one to deny the existence of ether, but ascribing a state of motion to ether was not possible. Lines of force for electromagnetic field could not be tracked though time. For special relativity, electromagnetic fields appeared as ultimate irreducible realities. Yet, Einstein realized that to deny the existence of ether is to assume that empty space has no physical qualities whatsoever, and the facts of mechanics do not harmonize with such a view. Indeed, in order to look upon the rotation of a system in free space as something real, Newton objectivized space, i.e. rotation relative to an absolute space is real.
Einstein eventually realized that space-time variability (of the reciprocal relations of standards of space and time) , or, the recognition of the fact that empty space in its physical relation is neither homogeneous nor isotropic compelled description of its states by ten functions (the gravitational potential guv). This perception had finally disposed of the view that space is physically empty. Einstein then believed that condensations of the electromagnetic fields could be termed “matter,” while gravitational field (or ether) could be termed “space.” Still, matter and space were separated conceptually, but connected causally.
