论物理时空的建构特征

On the Construction Characteristics of Physical Space-Time

摘要: 牛顿时空描述宏观低速物体的运动规律，狭义相对论时空描述宏观高速物体的运动规律，有引力存在的时空是弯曲时空。它们都是物理时空。目前，微观量子世界没有引入新的物理时空，微观量子现象分别描述在牛顿、狭义相对论或者广义相对论时空中。但是量子力学与狭义相对论，尤其是广义相对论之间存在许多不协调，至今难以解决。遵循卡鲁扎-克莱因路线，人们试图用弦论、圈论来统一量子力学与相对论，尤其是广义相对论，目前看来并不理想，数学形式太复杂，而物理内涵不清晰。遵循同样的路线，我们认为，如果承认物理时空具有建构特征，要消除主观认知对量子现象的影响，用双4维时空描述微观量子现象就比较理想，且量子力学与相对论之间存在的许多矛盾，也可以得到合理解决。场的统一似乎也有新思路。

Abstract: Newtonian space-time describes the law of motion of macroscopic low-speed objects, special rela-tivity space-time describes the law of motion of macroscopic high-speed objects, and the space-time with gravity is curved space-time. They’re both physical space-time. At present, the microscopic quantum world does not introduce new physical space-time. The microscopic quantum phenomena are described in the space-time of Newton, special relativity or general relativity respectively. However, there are many inconsistencies between quantum mechanics and special relativity, especially general relativity. People try to use string theory and circle theory to unify quantum mechanics and relativity, especially general relativity, which is not ideal at present. The mathematical form is too complicated and the physical connotation is not clear. Following the same line, we believe that if we recognize the construction characteristics of physical spacetime and eliminate the influence of subjective cognition on quantum phenomena, it is ideal to describe microscopic quantum phenomena with dual 4-dimensional spacetime, and many contradictions between quantum mechanics and relativity can be reasonably solved. The unification of the field also seems to have new ideas.
