Machine Learning vs Einstein Relativity – Looking at mu = 1/(sqrt(1-v**2/c**2)) reformat this into a pythagorean I guess that you get a causality hook when v changes with time and c changes ?temporarily due to a index of refraction. This causality will affect the velocity model?
So time the disturbance of c with the refraction and v with the acceleration and there is a chance of a |velocity effect|. Thats my guess. A shortpath to higher velocities. // Per
