空间定位的相对论“观测”修正原理与方法新探

本文针对地球卫星导航定位目前约定俗成的狭义和广义两个相对论的修正方法,从狭义和广义相对论的原理本质进行了研究与探讨。在狭义相对论的等效原理和拓展原理的基础上,对广义相对论重新认识,在分析其“佯谬”的基础上,进一步深入认知广义相对论的本质和局限性,提出了广义相对论的等效原理的设想,使得杨-米尔斯场的表达成为可能。随后还提出超光速拓展原理的设想。对现在使用的狭义和广义相对论的空间定位的使用方法做出了合乎客观逻辑的解释,从而提出了将实际操作也做出相应调整的重大建议。最后对以后广袤太空空间的相对论修正的使用提醒要回归相对论的本质以及注意实际操作的合理性。

Tests of gravitational symmetries with radio pulsars

Symmetries play important roles in modern theories of physical laws. In this paper, we review several experimental tests of important symmetries associated with the gravitational interaction, including the universality of free fall for self-gravitating bodies,time-shift symmetry in the gravitational constant, local position invariance and local Lorentz invariance of gravity, and spacetime translational symmetries. Recent experimental explorations for post-Newtonian gravity are discussed, of which, those from pulsar astronomy are highlighted. All of these tests, of very different aspects of gravity theories, at very different length scales, favor to very high precision the predictions of the strong equivalence principle(SEP) and, in particular, general relativity which embodies SEP completely. As the founding principles of gravity, these symmetries are motivated to be promoted to even stricter tests in future.
