如果基本常数（例如精细结构常数 α）与时空相关，那么原子光谱和时钟频率也是时空相关的。正如 Marianna S. Safronova 在文章编号 1800364 中所讨论的，原子钟的非凡改进使得能够以非常高的精度测试基本常数的稳定性。未来的核 229 Th 时钟可能比原子钟对 α 的变化具有更大的灵敏度。
If the fundamental constants, such as the fine-structure constant α, are space-time dependent so are atomic spectra and the clock frequencies. As discussed in article number 1800364 by Marianna S. Safronova, the extraordinary improvement of atomic clocks has enabled testing the constancy of the fundamental constants at a very high level of precision. A future nuclear 229 Th clock may have much larger sensitivity to the variation of α than atomic clocks.
