  11. Astronomers estimate the speed at which a galaxy is moving away by measuring the galaxy ' s redshift

  12. Continuing the above example, the galaxy is moving at a speed of about 9000km s away from us, given the speed of light is 3x10

    把數值代入，便可以得出以上例子的星系退行速度為每秒九千公里。
  13. American astronomer edwin hubble in 1929 discovered that the recession rate of galaxies was directly proportional to their distance. this is what we call the hubble s law which defines that v h

  16. If the redshift is much less than 1, we can calculate the receding velocity by the following formula

    若紅移z比1少得多則我們便可用以下公式找出星系的退行速度v ：
  17. We know how fast the galaxies are receding from us. so, if we run the movie of the universe backward, we can calculate how long it takes for the galaxies to get back together. from this, the age of the universe is about 15 billion years 1. 5 x 10

    利用大爆炸理論亦可以估算宇宙的年，由於我們知道星系的退行速度，只要我們來一個倒鏡，計算所有星系回到原點所需的時間，便可得出宇宙的年，結果是大約有150億年1 . 5x10
  18. M s. if the motions of the galaxies were random, then we would expect that about half of them will recede from us while half of them will be approaching us. however, hubble found that not only most of them are receding from us, but also the receding velocity is directly proportional to the distance away from us

    假若星系運動的方向是隨機的，那麼應該有一半的星系正在遠離我們，另一半則接近我們，但結果實在出人意表，哈勃發現不單絕大部分星系正在遠離我們，而且它們的退行速度和與地球的距離成正比，這個關系可以下式表示：
  19. There are two major errors. the first one is the error occurred in measuring v. although astronomers can locate v of individual galaxy accurately through the spectrum and the doppler s effect, owing to the gravitational pull exerted from neighbouring galaxies and clusters of galaxies, v is not wholly determined by the expansion of the universe

    有兩個主要的誤差：第一個是測量退行速度的誤差，雖然天文學家利用光譜及多普勒效應，已經很準確地找到個別星系的退行速度，但由於與鄰近星系及星系團的引力作用，這個退行速度便不完全是因宇宙膨
