I'm afraid, you infer too much from a mathematical formalism that is only good for calculations.

  No. I infer this from the experimental results that say that[1] there is no preferred inertial reference frame, the speed of light is the same constant in all of them, and to change from a the coordinate system from a inercial reference frame to another inertial reference frame that is moving with a constant velocity you must use the Lorentz transformations that mix the spatial and temporal coordinates, and this transformation and other similar results in Special Relativity are verified experimentally [1]. [1] In a small scale and where gravity is small enough to ignore General Relativity. But General Relativity doesn't solve the mixing problem, it make it worst.
