The Field Structure of Vacuum, Maxwell Equations and Relativity Theory   Aspects. Part 1
  The nature of space-time and surrounding matter objects was and persists to be a one of the most intriguing and challenging problems facing the mankind and natural scientists especially. As we know one of the most brilliant inventions in physics of XIX-th century was combining of electricity and magnetism within the Faraday-Maxwell electromagnetism theory. This theory explained the main physical laws of light propagation in space-time and posed new questions concerning the nature of vacuum. Nonetheless, almost all attempts aiming to unveil the real state of art of the vacuum problem appeared to be unsuccessful in spite of new ideas suggested by Mach, Lorentz, Poincare, Einstein and some others physicists. Moreover, the non-usual way of treating the space-time devised by Einstein, in reality, favored to eclipsing both its nature and the related physical vacuum origin problems \cite{Fe,Ga,Ma,TW,Ba,BP}, reducing them to some physically unmotivated formal mathematical principles and recipes, combined in the well known special relativity theory (SRT). The SRT appeared to be adapted to the only inertial reference systems and faced with hard problems of the electromagnetic Lorentz forces explanation and relationships between inertial and gravity forces. The latter was artificially "dissolved" by means of the well known "equivalence" principle owing to which the "inertial" mass of a material object was postulated to coincide with its "gravity" mass.   In work we try to unveil some nontrivial aspects of the real space-time and vacuum origin problems to derive from the natural field theory principles all of the well known Maxwell electromagnetism and relativity theories results, to show their relative or only visible coincidence with real physical phenomena and to feature new perspectives facing the modern fundamental physics.
