A diffraction pattern in a medium, and depending on that medium. That is, the effect is the result of an interaction. > > >> Or better yet: >> "We know the gravitational effect between two material bodies, but what is the gravitational effect of one material body?" > > Curves the metric. > > But without any other body in the universe there's nobody there to measure it.

In both cases it's just semantic games with an undefined term. In the question regarding the tree, the phrase "make a sound" was never defined and so the issue appears debatable. In your example, the word "effect" was never defined, and so the question appears debatable. The question is debatable. Although only semantically, if you like. If you define sound as "something audible" then it only occurs when someone hears it, by definition. But if you define "sound" as something that has the possibility of being audible, then there's sound even when nobody hears it, again by definition. And this is the right way to define it, IMO, because if not, you're left in the dark regarding the real nature of things. The specific phenomena of sound manifests when somebody hears it, but while nobody is hearing it, there's something there that, when someone heards it, manifests itself as sound. But I was pointing to another direction: trying to show that the specific form of things we perceive or phenomena that occurs in the world, are the result of an interaction. In the same venue, gravity only makes sense as a result of the interaction of two or more massive bodies. In a sense, gravity phenomenologically IS the result of that interaction, that is, gravity is different when there's an interaction, to when there's none, and that difference depends also on the interacting bodies, in the same way as a diffraction pattern depends on the medium, and an interference pattern depends on the specific encounter of two beams. So, to the point. Here are my reflections: Gravity is a form of interference pattern between two or more bodies. Gravity is a standing wave formed by the superposition of two (or more) waves, and from this superposition the effects of gravity arise. This way of seeing gravity has some advantages to the classical one(point forces) and to the relativistic one (curved metric): - gravity has now a mediator(a gravitational wave). - gravity is a specific property of matter(a 3D pulsation, equivalent to a 4D rotation). - gravity is dynamical, i.e. can be defined as a flux, which has a local intensity. - gravity acts on all levels, but that action depends on the interaction of two or more things. So, this model of gravitation can explain why the electron does not collapse into the nucleus, and why the Moon does not collapse on the Earth. It can also explain how momentum is mediated("transferred") between celestial bodies. - finally, this model of gravity has also a repulsive aspect, not only an attractive one. When the bodies are equilibrated, the standing wave formed prevents both the escape of the small body from the influence of the bigger one(i.e. an attractive "force"), AND its collapse into the bigger one(i.e. a "repulsive" force). Collapse is the result of the bodies being out of equilibrium, that is, mass differences being too big to be "resolved" or equilibrated at any point (except cero) at that distance. In equilibrium, the bodies are "locked in" into a resonating standing wave. This explain the different electronic orbits as being no more than different instances where wave equilibrium is produced between the waves of electrons and protons. Finally: what's the specific form of these gravitational waves? As we've seen in the past, a 4D rotation is "proyected into" 3D space as a pulsation. And the propagation of a pulsation into 3D space is a longitudinal wave. So gravity as a mediator is a longitudinal wave, of a specific frequency and intensity, which is assimilable to a scalar field, but it is not (not only, at least) a scalar field. The interaction of different longitudinal waves of this kind, produces the effects of gravity we all know, and many other effects, some of which are known to a certain extent, and some of which are ignored to another, much greater, extent. I'm attempting now a mathematical formulation of all this, although the issue is clearly beyond my actual knowledge. And also beyond my time schedules :-) A specific understanding of inertia, and particularly, its specific interaction or relation with gravity, is also still lacking, or better said, it's not completely visualized or modelled at the moment. Best regards, commenst are welcomed as usual. If you think or feel you can come up with a mathematical formalism contact me in private for more details or questions. Mauro
