大約就在愛因斯坦為自己的理論添上一個常數(shù)的時候，在亞利桑那州的洛厄爾天文臺，天文學家維斯托?斯萊弗在記錄遠方恒星的光譜圖上的讀數(shù)，發(fā)現(xiàn)恒星好像在離我們遠去。斯萊弗發(fā)現(xiàn)，這些恒星明確顯示出一種多普勒頻移效應的跡象。因為離我們遠去的光是向光譜的紅端移動的，而朝我們射來的光是向藍端移動的~~~

文中需聽寫單詞或詞組用[-No-]表示，句子用[---No---]表示。請邊聽寫邊理解文意，這樣可以提高聽力準確度，并為訓練聽譯打下基礎哦~~~

just as you would expect of anything that is being pushed from behind toward an immobile object.

As the sound source passes, the sound waves spread out and lengthen, causing the pitch to drop abruptly
說來也巧，大約就在愛因斯坦為自己的理論添上一個常數(shù)的時候，在亞利桑那州的洛厄爾天文臺，有一位天文學家在記錄遠方恒星的光譜圖上的讀數(shù)，發(fā)現(xiàn)恒星好像在離我們遠去。該天文學家有個來自星系的動聽名字：維斯托?斯萊弗（他其實是印第安納州人）。原來，宇宙不是靜止的。斯萊弗發(fā)現(xiàn)，這些恒星明確顯示出一種多普勒頻移的跡象--跟賽車場上飛馳而過的汽車發(fā)出的那種連貫而又特有的"嚓--嗖"的聲音屬于同一機制。這種現(xiàn)象也適用于光；就不停遠去的星系而言，它被稱之為紅移（因為離我們遠去的光是向光譜的紅端移動的，而朝我們射來的光是向藍端移動的）。
