Summary (closing paragraph):
The leading characteristic of the non-Einsteinian structural theory of relativity lies precisely in the fact that both the medium where natural events take place and the events themselves have a definite "intrinsicality" of their own. Only through the reciprocal relation between medium and testable events can the latter assume their characteristic determination, which is expressible by means of a mathematical equation. The constancy of the velocity of light is also determined through the constant relation between light and the medium where it propagates. In general relativity, only Riemann?s space is suited to represent the continuous non-homogeneous reality, while the Lorentz-transformations can only describe ? in an abstract an altogether elementary form ? the variability of the spatial-temporal measurements of a natural event, such as they represent themselves to a moving observer, but without any special meaning. Only a non-Einsteinian structural theory of relativity can reach reality in its deep tensorial essence, accounting for such relativistic calculations as are necessary to modern variable mass mechanics, and definitely ruling out, at the same time, all those scientific and philosophic inferences which have been ambiguously drawn from Einstein?s artificial problem of special relativity.
