  12. We found that the luminosities of type i supernovae are about the same. therefore, we can compute the distance to a galaxy by measuring the apparent brightness of a type i supernova in that galaxy, if we can find one

    科學家發現原來所有這種超新星爆發的光度都是差不多的,所以我們只要找到這種超新星,便可以由它的視亮度推算出它和地球的距離,從而得知它所處身星系的距離。
  13. The farther away the supernovae are, the longer their light has been traveling and the further back in time the explosion occurred

    超新星越遠,它們的光旅行的距離越長,爆炸發生的時間就越古老。
  14. The two of us proposed that observations of more high - redshift supernovae could provide definitive proof and pin down the transition from slowdown to speedup

    我們曾經提出,只要觀測更多高紅移的超新星,就能提供更明確的證據,並精確量測出宇宙由減速過渡到加速的整個過程。
