By proceeding in this way, did Einstein not miss a final opportunity to go directly towards the ultimate physics which unifies everything, especially his two theories?
In our preprint*, we present the side c' as a value according to Pytaghor's theorem for right triangles. However, our preprint* gives another equation for c', for exactly the same value given by Pytaghor's theorem for right triangles. This makes the unification of physics completely possible.
Preprint*: Time dilation as an intrinsic property of light explaining the constancy of the speed of light regardless of the reference frame of measurement.
