**Abstract:**

Many physicists believe in Einstein’s theory because they have never read his papers. In his most “famous” paper [1] Einstein postulated that the speed of light is constant in all coordinate systems. This postulate is obviously absolute nonsense, because a coordinate system is a mathematical construction without physical meaning. A coordinate system exists only in the thoughts and has no restriction with regard to its speed.

No, that is not a wrong interpretation. The velocity relative to the rod is to be determined. The velocity of light relative to the system at rest is given. The light path relative to the system at rest has changed, but not relative to the moving system (rod). Your interpretation is absurd.

In the article, first page I read:

"In the system which is thought of as being moved, the speed of light along x-axis

(“moving” rigid rod) is c-v and c+v according to Einstein."

This is a wrong interpretation of Einstein.

For the "stationary" observer (for him the rod moves at speed v), the travel time of the light beam

can be found with t1=(L+v.t1)/c to the end of the rod and t2=(L-v.t2)/c for the trip back.

So t1=L/(c-v) and t2=L/(c+v). (L is the length of the rod). Note that light speed is c all the time !
