A Presently Overlooked Explanation for the Constant Speed of Light, Relativistic Effects and Magnetic Force

This study discusses a new, unusual but simple explanation for the constant speed of light, some relativistic effects and magnetic force. The starting point of the discussion is a single, plausible postulate which links the principle of relativity with a constant speed of light for all inertial observers without space and time assumptions. The postulate makes it possible to further explain the effect of time dilation, relativistic Doppler effect and Lorentz force. This study also shows that the concept leads almost, but not exactly to the special theory of relativity. It is surprising that this approach has not been discussed to date. Because of its high interpretive power, the conclusion is that the hypothesis remains completely unexplored.
