# Criticism of SRT: Proof that the Earth is not rotating around the SUN. EXPLANATION

## The source of the paradox...

...is that the problem of rotational motion must be solved with the help of GRT. The mistake made by Hafele and Keating was treating this problem using SRT which, on the other hand, required some false assumptions which led to this paradox. Eventually, Hafele and Keating proved the GRT while they were convinced that they proved the SRT.

 CORRECT SOLUTION We MUST start the solution from the space-time interval equation for rotational motion in gravitational field (rs it's Schwarzschild radius of a gravitational source). Adding a very small factor (on the yellow background in the fig. below) we obtain the final formula: WRONG SOLUTION The solution of the problem of rotational motion, commonly applied in papers concerning rotational motion of planets, satelites of GPS system etc. is based on WRONG ASSUMPTION that we can temporarly assume the motion as if it was the inertial one. Such assumption was made by Hafele and Keating and it allowed to draw the idiotic proof that Earth is not rotation around Sun - for more detail explanation see the previous page and the references mentioned there  substituting we eventually obtain: Assuming temporarly an intertial motion we obtain factor describing the time dilation as a result of inertial motion: (1-V2/c2) and introducing a gravitational field we obtain factor describing a gravitational time dilation: (1-rs/r) where rs it's Schwarzschild radius of a gravitational source and r is the radius, the objetct is rotating aroundwe obtain the following formula: For the first glance, the both formulas - the one derived on the base of GRT (the "correct" solution) and the one derived on the base of SRT (the "wrong" solution) are identical, therefore the way of derivation of the formula does not matter form point of view of computational results. THEREFORE, IS THERE ANY REASON TO TALK ABOUT IT? YES - IF WE WANT TO FIND OUT INFORMATION CONCERNING THE ORIGIN OF THE TIME DILATION PHENOMENON In the case of proper - GRT based - solution, the Velocity in the formula (on the yellow background) is corresponding to the rotational motion, It means that the source of time dilation is the change of the velociny - more detail: the change of direction of the velocity In case of wrong - SRT based - solution the velocity in the formula is corresponding to the linear motion. It means that the source of time dilation is only velocity and change of the velocity has nothing to do with the time dilation phenomenon. Starting either from porper or wrong approach we obtain the same formula, then the result of computation does not depend on the choice of method, the problem is considered with. Computational results of the time dilation phenemoenon will be almost identical as well for the wrong as the correct method. The difference will appear when we try find the real mechanism responsible for the time dilation. Applying the wrong method we are convinced that only the velocity causes the time dilation. Therefore the majority of physicists belives that the time dilation in case of motion of GPS satelites or jets in the Hafele and Keating experimemt etc. are the proof for the SRT. THE REASONING PRESENTED ABOVE AND IN THE PREVIOUS CHAPTER SAYS THAT IT IS NOT TRUE The true mechanisms responsible for time dilation phenomenon are the velocity together with the change of the velocity an the problem can be solved properly with the help of GRT. The SRT-type formula is only the aproximation of the GRT solution and it can give us the false impression that the time dilation is a result of SRT while in fact it is result of GRT (although computations made with SRT method give correct results). If the time dilation in case of the rotational motion can not be a result of SRT as it has been assumed up to now, then maybe other experiments which were assumed to be the proof of the SRT, were in fact the proof of GRT as it took place in case of rotational motion???
