n.〈天〉(天體)紅移;紅向移動
The foreground galaxy lies at a redshift of 0.39. 前臺銀河在于在紅移為0.
The quasar lies at a redshift of 1.41. 類星體是在紅移1.
Spacetime must be somehow granular to tame the dubious infinite redshift. 時空必須要有某種顆粒性來馴服曖昧的無限紅移。
Misunderstandings about the relation between redshift and velocity abound. 關(guān)于紅移與速度之間的關(guān)系,也有不少誤解。
Redshift is a measure of how fast a celestial object is moving relative to us. 紅移可以用來計算一個天體相對我們運動的速度。
