The scientists observed many supernovae at different distances to determine how fast they are speeding away from us. (They measured the objects’ red-shift, or how much their light had been changed due to the Doppler Effect, which is the compression or expansion of waves that occurs when an object is moving toward or away from you. An analogy is the siren of an ambulance that changes pitch as it moves toward you, then passes you and heads the other way — its waves are first compressed, then stretched.) These measurements gave astronomers a picture of how fast the universe was expanding at different points in its history.

Answer 1

科学家们观测到的超新星在不同距离来确定多快离我们远去。(他们测量对象的红移,或有多少他们的光被改变了由于多普勒效应,即压缩或膨胀波的发生在一个对象正朝着或远离你。类比是救护车的警笛声,改变音高,走向你,然后通过你和其他的方式——它的波第一次压缩,然后伸展。)这些测量了天文学家的照片,宇宙扩张速度在不同的历史。
