论文摘要
试图统一四种基本相互作用和重力理论的理论可以预测自然基本常数的时间和/或空间变化。这些理论的不同版本可以预测这些变化的不同行为。因此，实验和观察界限是检查此类建议的有效性的重要工具。在本文中，我们回顾了对基本常数可能从天文观测和地球物理实验的可能变化的限制，旨在测试不同时间尺度上自然基础常数的恒定量。我们还专注于可以从白色矮人获得的限制，这些限制可以限制具有重力潜力的常数的变化。
Theories that attempt to unify the four fundamental interactions and alternative theories of gravity predict time and/or spatial variation of the fundamental constants of nature. Different versions of these theories predict different behaviours for these variations. In consequence, experimental and observational bounds are an important tool to check the validity of such proposals. In this paper, we review constraints on the possible variation of the fundamental constants from astronomical observations and geophysical experiments designed to test the constancy of the fundamental constants of nature over different timescales. We also focus on the limits that can be obtained from white dwarfs, which can constrain the variation of the constants with the gravitational potential.
