大约就在爱因斯坦为自己的理论添上一个常数的时候，在亚利桑那州的洛厄尔天文台，天文学家维斯托•斯莱弗在记录远方恒星的光谱图上的读数，发现恒星好像在离我们远去。斯莱弗发现，这些恒星明确显示出一种多普勒频移效应的迹象。因为离我们远去的光是向光谱的红端移动的，而朝我们射来的光是向蓝端移动的~~~

As the sound source passes, the sound waves spread out and lengthen, causing the pitch to drop abruptly
说来也巧，大约就在爱因斯坦为自己的理论添上一个常数的时候，在亚利桑那州的洛厄尔天文台，有一位天文学家在记录远方恒星的光谱图上的读数，发现恒星好像在离我们远去。该天文学家有个来自星系的动听名字：维斯托•斯莱弗（他其实是印第安纳州人）。原来，宇宙不是静止的。斯莱弗发现，这些恒星明确显示出一种多普勒频移的迹象--跟赛车场上飞驰而过的汽车发出的那种连贯而又特有的"嚓--嗖"的声音属于同一机制。这种现象也适用于光；就不停远去的星系而言，它被称之为红移（因为离我们远去的光是向光谱的红端移动的，而朝我们射来的光是向蓝端移动的）。
