In the same context a vector field Eg, that is not associated with anything substantial, has been introduced as the entity that mediates in the gravitational interactions. In this article, we will show that Egis the mathematical quantity that—at the macroscopic level—fully characterizes the medium that makes the interaction between particles at rest possible. We identify that medium as “the gravitational field”. To define the nature of the gravitational field, we will start from the hypothesis that a material object manifests itself in space by the emission—at a rate proportional to its rest mass—of mass and energy less granular entities that—relative to an inertial reference frame—are rushing away with the speed of light and that are carriers of information referring to the position of their emitter (“g-information”). Because they transport nothing else than information, we call these entities “informatons”. We will show that the expanding cloud of g-information created by the continuous emission of informatons by a mass particle at rest can be fully characterized by the vector field Eg, which implies that that cloud can be identified as the gravitational field of the particle. We will also show that the gravitational interaction between mass particles can be explained as the response of a particle to the disturbance of the symmetry of its “proper” gravitational field by the field that, in its direct vicinity, is created and maintained by other mass particles.展开更多

It has been showed that, on the macroscopic level, that medium—the “gravitational field”—manifests itself as the vector field Eg. In this article we will deduce from the postulate of the emission of informatons, that the informatons emitted by a moving mass particle carry not only information about the position (g-information) but also about the velocity (“β-information”) of their emitter. It follows that the gravitational field of a moving mass particle is a dual entity always having a field- and an induction-component (Egand Bg) simultaneously created by their common sources: time-variable masses and mass flows and that the gravitational interaction is the effect of the fact that an object in a gravitational field always tends to become “blind” for that field by accelerating according to a Lorentz-like law.展开更多
