或许很多人还没有察觉到,高处除了“不胜寒”以外,还有更要命的地方。最近,美国物理学家们使用原子钟在不同高度位置检测时间是否会发生变化,结果发现了一个非常奇妙的现象:位置每升高一英尺(约33厘米),两地的时间在一年中就相差10亿分之一秒。 Perhaps many people have not yet noticed that heights are more deadly than “being overwhelmed”. Recently, the use of atomic clocks at different altitudes in the U.S. physicists to detect when the time would have changed would have revealed a very curious phenomenon: for every one foot (33 centimeters) at each location, the time between the two places was within a year A difference of one billionth of a second.
