The fine structure constant, and other fundamental constants, are absolutely central to our current theory of physics.
微细构造常数和其他基本常数都无疑是我们现在研究的核心。
Constant flexing of the structure concentrates stress, which leads to microscopic cracks.
这些构造部位的频繁伸缩使应力集中，导致微裂纹的产生。
The only feasible explanation was that a constant of physics called the fine structure constant, or alpha, had a different value near the time the light started its journey.
唯一可能且合理的解释是：一个被称之为“精细结构常数”或α的物理常数，在临近启程的那段时间产生了一个不同的值。
