Einstein's used Voigt's relativity equations from 1887 in his 1905 Special Relativity paper, but Einstein tried to derive them without an electro-magnetic, waving medium. This leads to a self-contradiction in Einstein's SR paper (described below). In Section 1 of his paper, he defines a NON-Relativistic math equation using a LIGHT SIGNAL at the speed of light (c). In Section 2, he uses this LIGHT SIGNAL math formula to show that the moving frame observers would NOT see equal forward and reflected LIGHT SIGNAL timing, which means "clocks NOT synced." BUT, in beginning of Section 3, he uses this same Non-Relativistic LIGHT SIGNAL math to show that clocks CAN be synced in the moving frame! Why? How? What changed? 🤷‍♂️ BOTH the stationary and moving reference frames can measure the LIGHT SIGNAL at speed "c" via NON-Relativistic math by syncing the clocks! Later in Section 3, Einstein contradicts this by claiming the Relativistic math is needed to have light measured in the moving frame with the velocity of c: Einstein re-used Voigt's equations in his 1905 Special Relativity paper and never cited Voigt's Doppler Principle paper from 1887. Einstein's LIGHT SIGNAL math was used as an ATTEMPT to derive Voigt's equations, but fails due to the contradiction of getting two opposite answers for the moving frame using same math equation. How is that possible? 🤷‍♂️👇 Einstein simply changed the LIGHT SIGNAL emitter to the moving frame, where there is no distance change between the LIGHT SIGNAL emitter and the reflecting point, as seen below in the Section 3 math. Voigt's relativistic transforms recognize the speed of light as a CONSTANT wave speed in the light medium, but Einstein tried to do away with this aspect of Voigt's equations by creating the "speed of light in empty space" concept. In doing so, Einstein's derivation attempt is self-conflicting, since relativity is based on an object's movement relative to the light emitting source (Doppler Effect of the wave medium).
