"Now we have an explanation," Flambaum said. "If fundamental constants vary in space, we just appear in the area of the universe where constants are good for us."
“现在我们有了一种解释，”Flambaum说，“如果精细结构常数随空间变化，我们就只是恰好存在在宇宙中这些常数适宜我们的地区罢了。”

概括介绍目前电学计量的基本状况和能力，说明电学计量的主题领域范围、与基本常数的关系。
Unfortunately we are unable to test any of these theories as we cannot experience (and measure) the fundamental constants in alternate universes (if they exist), so this is a speculative study.
不幸的是因为我们无法体验(并测量)其它宇宙(如果存在的话)中的基本常量，因此我们无法验证这些理论，所以说这是一个推测性的研究。
Fundamental constants such as the strength of the electromagnetic force - the so-called fine-structure constant, or alpha - get their name from the fact that they are supposedly the same everywhere.
宇宙基本常数，比如电磁力强度之类的精细结构常数，符号位“alpha ”，它们因为被假定为不变量而得名。
