论文摘要
类星体光谱的最新更新结果表明，高结构常数空间变化的3.9 $σ$。从理论上讲，重要的是要检查量子理论的基本常数是否会随空间和时间而变化。在本文中，我们探讨了高结构常数的空间变化可能与爱因斯坦的总体相对论兼容的可能性。也就是说，宇宙中的空间依赖性细胞结构常数可以起源于不同的局部框架中光速的不同值，因为我们知道在重力或非惯性运动的当下光线必须弯曲。此外，为了了解有关FLRW时空的各向异性坐标的更多信息，我们还研究了光度距离距离红移关系。发现在高红移状态下存在偶极子结构，而在低红移状态下，没有这样的偶极子。
Recent updated results of quasar spectra suggested a 3.9$σ$ significance of spatial variation of the fine-structure constant. Theoretically, it is important to examine whether the fine-structure constant, as a fundamental constant in quantum theory, is possible varying with space and time. In this paper, we explore the possibility that spatial variation of the fine-structure constant could be compatible with Einstein's general relativity. Namely, the spatially dependent fine-structure constant in the Universe could be originated in different values of the speed of light in separate local frames that are far away from us, since we have known that light rays must be bending in the present of gravity or non-inertial motions. In addition, to learn more about the anisotropic coordinate of FLRW space-time, we also study luminosity distance-redshift relation. It is found that there is a dipole structure in high redshift regime, while in low redshift regime, there is not such dipole.
