Tachyons And Modern Physics

ABSTRACT We have carried out an exhaustive analysis of the scope of Relativity showing that it is possible to couple it with Quantum Theory but not with Classical Mechanics In order to do that we have introduced the concept of electromagnetic and virtual mass to all particles subjected to Quantum Field Theory radically different from the real or inertial mass included in Newtonian Dynamics which turns out the adequate status to understand quantum phenomena without resorting to explanations difficult to admit. In that line we have considered the particles so-called Tachyon for which we made a reformulation of the relativistic equation avoiding the space-like or negative interval non-causal thus it has been demonstrated its identification with antiparticles on account of the peculiar behavior of energy and momentum regarding the particles and photons.
