The theory of relativity has been at the pinnacle of human scientific thought for 120 years. However, whether it should continue to lead is a question for us. Voices questioning the theory of relativity have been continuing, but since they are mostly from a mathematical or experimental point of view, they have not yielded convincing results. We have pioneered a new way of analyzing mathematical models from the perspective of reviewing the rationality of physical models, thus we have seen many problems with relativistic models from different perspectives. For theory of special relativity, we have grouped into four general concerns and 12 obvious or easy to prove problems. More important, we deducted and thoroughly proved "Limited Effect Principle of a Relativistic Systems." It tells us the theory of special relativity is a pure fantasy theory. We made rational definitions of space, time from the basic elements. This would end the confusion about the understanding of the concepts of space and time. Through these intuitive discussions, we believe that the theory of relativity gave us abundant fantasy, but not scientific theory. It should no longer lead the scientific and technological thinking of mankind.
