Relativity, Gravitation

The unification of the laws of physics resolutely stands out from the classical theory of relativity mainly due to the considered spatial dimension. An examination of the concepts of the theory of relativity shows that the axial direction in which light propagates is subject to the Lorentz transformation while the other two transverse coordinates are not subject to this transformation. Returning to classical mechanics makes it possible to put forward the physical homology between Newtonian mechanics and relativistic mechanics. Space–time deformation due to the presence of a massive body is a concept of the theory of general relativity, an ad hoc notion that has important consequences for the understanding of physical phenomena and prevents any possible unification of the laws of physics, including quantum mechanics. Radiation redshift corresponds to a loss of energy of the particles when they travel through an inhomogeneous gravitational field, the intensity of which decreases along its path.
