Why a blog in topic with gravity nature ? Because Marius and I think that it is the mother of all the unanswered questions in cosmology.
In the blog we present a “non conventional” gravitational theory based on classic mechanical principles, on the model of that one theorized by Georges Louis Le Sage
in the half of XVIII century. Particularly, as we’ll see in the next articles, turns out basic the concept of gravity as a compressing force. The goal is to substitute the "unnatural" concepts of "remote action" or space time curvature with a less "metaphysical" model.
In the theory gravitational waves, thought by General Relativity as space time perturbations, are pressing waves of electromagnetic nature in an euclideus three dimensional space. The appearing of reciprocal attraction between two masses in reality turns out to be a simple effect of mutual shield from the waves given by the masses with consequent “decompression” of the surfaces and relative tidal effects.
Earth and Moon, for example, are both subject to a gravitational flow directed towards their internal. The flow is made up by perturbation created by their masses in a space set up by sinusoidal transversal and symmetrical waves that generate, by interference, stationary ones. The first waves, no more balanced, spreads from external to internal of the masses. The flow is proportional to the matter density. Consequently to the "shielding effect" Moon tends to be pushed towards Earth and vice versa. The orbital motion re balances the system.
Interferometers try to detect here on the Earth the waves generated by far highly perturbed systems as those ones of supermassive celestial bodies. Really the same waves would be present also in weakly perturbed systems as the Earth - Moon one. The reason for which these systems are not taken in consideration is that the gravitational “signal” would be too much weak. Moreover anomalies of trajectories of extrasolar space probes Pioneer suggest that effective intensity and range of action of gravitational waves are, probably, bigger than the theoretical ones. Then, if really gravitational waves would be pressing waves, at their passing everything (interferometers including), would be affected by an elastic deformation with the result that, from the “before” to the “after” of the passage, for the instrument wouldn't be any difference. This is the reason for which, for this kind of waves, could be much useful an high sensitive seismograph mounted on gimbals and placed in orbit (for example on SSI), so as not detect the Earth's microseismic events.
