Spatial variation in fine-structure constant

Quasar absorption lines provide a precise test of whether the fine-structure constant, {alpha}, is the same in different places and through cosmological time. We present a new...类星体吸收线（Quasar absorption lines）可用于高精度检验精细结构常数（fine-structure constant，α）在不同空间位置与宇宙学时间进程中是否保持恒定。我们提出了一项全新的……
