Texts like this can often be seen in China, where there is no shortage of "emperor's ministers" who praise Einstein and the theory of relativity. What are the facts? The theory of relativity is useless and cannot even calculate the simplest planetary orbits. If I ask you, does GPS need to use the theory of relativity? You will tell me firmly that this is necessary. But is it really necessary? Engineers and Honest GPT will tell you that GPS has never needed the theory of relativity in engineering. There is so much praise for the theory of relativity that as a science relativity is ridiculous and as a cult it is successful.
