Since OPERA is a very carefully designed experiment thus the sobering importance of its result, coupled with decades of some successful tests of special relativity theory (SRT) requires certain adjustment in our usual manner of thinking, and seriously prompts us to consider alternatives which should be consistent with both. To this end, we propose an alternative model as an explanation to the observed neutrino superluminality based on the universality of the well-known rest mass energy formula, and the idea that, at superluminal level, the velocity of a particle with real mass may be simultaneously dependent on its energy ratio and the kinematical attainability parameter. By raising this idea to the status of a hypothesis, we show that not only the OPERA result is very realistic but also is perfectly consistent with supernova SN1987a measurement. Consequently, SRT is not violated by the existence of superluminal particles since it is conceptually, physically and exclusively valid at subluminal level for relativistic velocities. As a direct consequence, the Minkowski space-time and Lorentz transformations are coherently extended to superluminal velocities.
