Inspired by the author 's Riemann hypothesis, this paper attempts to solve the contradiction between general relativity and quantum mechanics in physics. Under the guidance of Euler identity, two important ideas of collision and vibration are introduced. It is concluded that quantum mechanics cannot describe gravity because gravity cannot constitute this dimension of substance. The document deeply discusses the relationship between substance dimension and energy, including the stability and change of dimension, the relationship between energy and substance, and the relationship between time and dimension. It mainly introduces how different dimensions of substance interact, the generation and transformation of energy, and the influence of dimensional changes on substance. This paper discusses several theories that are expected to become GTU, points out their advantages and disadvantages respectively, and explores some non-physical humanistic philosophical problems. The reason is that there is an essential difference between the earth and other substances.Finally, the article clarifies the current problems in human society. Excessive materialism causes human beings to be at a special node ( 1 + 1 = 2 ), and finding a way to become a multi-dimensional structure again ( 1 + 1 + 1 = 3 ).
