The researchers found that in the northern sky, the fine-structure constant gets smaller with increasing distance, or as astronomers look farther back in time.
研究人员发现在北方天穹，精细结构常数在越远的地方就越小，或者说天文学家所看到的过去越久远。
Slightly belying its name, the fine-structure constant is actually a compound of several other physical constants, whose values can found in any physics textbook.
精细结构常数实际上是其他几个能在任何物理学教科书中找到数值的物理常数合成，同它的名称稍微有些名不副实。
This frequency depends on the fine-structure constant.
该频率取决于精细结构常数。
For more than 20 years, some researchers have found what they think is evidence that the fine-structure constant varies over time.
20多年以来，一些研究学者一直致力于寻找精细结构常数是变化着的的证据。
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。
Astrophysicists have been studying the fine-structure constant? Known as the alpha constant? For years, searching for hints that it might change.
天体物理学家多年来一直都在研究精细结构常数——称为alpha常数——寻找它可能发生变化的蛛丝马迹。
And the fine-structure constant will have shown itself to be more mysterious than even Feynman conceived.
此外，精细结构常数将表现得比费曼想象的更奇幻得多。
Astrophysicists have been studying the fine-structure constant - known as the alpha constant - for years, searching for hints that it might change.
天体物理学家多年来一直都在研究精细结构常数——称为alpha常数——寻找它可能发生变化的蛛丝马迹。
Over billions of light years and looking back billions of years in time, we now know that the fine-structure constant hasn't changed any more than about .001 percent.
在那几十亿光年以外的地方，回头看数十亿年时间，我们现在知道，这个精细结构常数并没有任何超过1/100000。
Instead, this' magic number 'known as the fine-structure constant —' alpha 'for short — appears to vary throughout the universe.
并且，被称作“魔幻数字”的微细构造常数(缩写为‘alpha’)似乎在整个宇宙中不停的变化着。
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。
The number he was referring to, which goes by the symbol alpha and the rather more long-winded name of the fine-structure constant, is magic indeed.
他所指的数字依据字母阿尔法和一个更加冗长的精细结构常数，该数的确神奇。
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。
