Dear Vladimir,
Thanks for your comments on my essay and for your remarks about my "Theory of Informatons" that is developed thouroughly in ref 6 and in ref 7. In the frame of that theory, the concept "information" has a specific meaning.
1. When we say that it is the substance of gravitational and electromagnetic fields, we mean that "information carried by informatons" makes these fields what they are: not just mathematical constructions but elements of the natural world.
2. The constituent element of that substance is called an "informaton". The theory starts from the hypothesis that any material object manifests itself in space by emitting informatons at a rate that is proportional to its rest mass: the rest mass is the only factor that determines the rate at which an object emits informatons. Informatons run through space with the speed of light.
3. The fundamental attribute of an informaton is called its "g-index". The g-index of an informaton refers to information about the position of its emitter. It is the only attribute of an informaton emitted by an electrically neutral object at rest. It is represented by a vectorial quantity {s-g} that points to the emitter and whose magnitude is the "elementary quantity of g-information". Macroscopically, the density of the flow of g-information in a point is identified as the "g-field" {E-g}.
4. Informatons emitted by an electrically charged object at rest have moreover an attribute that refers to information about the electrical status of their emitter. This attribute is called the "e-index". The e-index of an informaton refers to information about the sign of the charge, about the position and about the ratio of the quantity of charge Q to the mass m of its emitter. The e-index is represented by a vectorial quantity {s-e} that is on the line connecting the informaton with its source, the magnitude of {s-e} is proportional to Q/m. Macroscopically, the density of the flow of e-information in a point is identified as the "e-field" {E}.
5. An object at rest emits informatons whose g-index (and whose e-index) has the same direction as their velocity {c}. This is no longer the case when the emitter is moving. How greater the speed of the emitter, how greater the deviation of {s-g} (and of {s-e}) relative to {c}: this deviation is characteristic for the speed of the emitter. The additional attribute of an informaton referring to g-information about the status of motion of its emitter is called its "beta-index" ("b-index" in relation to e-information). The beta-index is represented by a vectorial quantity {s-beta} that is perpendicular to the plain ({s-e},{c}) ("corkscrew effect"), the magnitude of {s-beta} is proportional to the component of the velocity of the emitter that is perpendicular to the velocity of the informaton. The analogue attribute in relation to e-information is called the "b-index" {s-b}. Macroscopically,the density of the cloud of beta-information in a point is identified as the g-induction {B-g}, and the density of the cloud of b-information as the magnetic induction {B}.
6. The theory of informatons explains gravitational and electromagnetic forces as the reaction of a material object on the disturbance of the characteristic symmetry of its "own" cloud of g/e-information by the flux of g/e-information emitted by other objects. There is no mechanical interaction between informatons and matter: informatons are mass and energy less entities.
7. The theory of informatons explains why gravitational and electromagnetic fields are isomorphic. From its starting points it follows that its scope is limited to the spacetime of the SRT and that its results are in line with this theory.
From 5 and 6 it follows that the interaction between moving masses/charges is governed by the "right-hand rule".
I wish I had your talent to describe my ideas in a less mathematical way and with more imagination. My style is the result of my studies in the applied sciences at the University of Ghent in the period when you visited our historic city with its numerous monuments and works of art.
With the best wishes,
Antoine
