The biggest theory in the XX century is the Special Theory of Relativity (SR), consequently, the General Theory of Relativity (GR), which has even now millions of followers and was accepted as a revolutionary theory of physics by the physical community. Special Relativity based on Lorentz transformation and Minkovski geometry forms the basis for the disciplines of Cosmology (the structure and origin of the Universe on the largest scales). A key postulate of special relativity is that the vacuum speed of light is the same for all observers. But the research aims to focus on how physics describes SR, which has some flaws from the beginning, andfinally, to show its some alternative versions

Keywords : Lorentz-factor, Minkovski geometry, the same unit in space-time, the multiverse of the Special Relativity in different speed limits.
