It is said that the theory of relativity and quantum theory are independent of each other. Their relationship is like water and oil. Now, it is very important for modern physics to synthesize them. In Physics and mathematics, Super String theory is studied, but instead of it, the tendimensional world appears. Our world is a three-dimensional world. What is the ten-dimensional world? It is more difficult than the string which is of Plank length. In the ten dimensional world, physics is (...) facing darkness and nothingness which man can not explain with the traditional physical words.The solution depends upon philosophy. I tried to synthesize themand succeeded.The following is an outline of my synthesis. 1. Utility and relativity of mathematical truth Mathematical truth is not absolute but relative. In the universe ( outside the solar system ), there is no perfect line. Because, by the gravitation of large astronomical bodies, space and lines are curved. Mathematical figure and numeration depend upon the promise of mankind. These are not absolute. Physics, which is grounded upon mathematics in certainty, is also relative. It expresses not the whole of the universe but a part of the universe. 2. Community and difference between the theory of relativity and quantum theory Community is the negation of absoluteness of physical attributes. Difference is the assessment for mathematics. The theory of relativity relies on mathematics but quantumtheory does not always rely on it. According to circumstances, Niels Bohr and quantum physicists abandoned a frame of reference. 3. The origin of the theory of relativity 4. The origin of quantum theory In short, the theory of relativity and quantum theory are not perfect, they only irradiate a part of the universe. Man can reach the whole of the universe only by the philosophical intuition of nothingness and infinite (the principle of nothingness and love). (shrink)
