recession of galaxies 中文意思是什麼
recession of galaxies
解釋
星系退行-
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
美國天文學家哈勃於1929年發現星系退行速度與其距離存在著正比的關系，即所謂哈勃定律：退行速度v h -
That history is encoded in the relation between the distances and recession velocities of galaxies
而這段歷史就潛藏在星系的距離和其遠離速率的關系當中。 -
From hubble s law, we know that measurement of recession rate of celestial objects mostly clusters of galaxies and distances are the pre - requisites for the search of h
，先要測量出天體主要是星系團的退行速度和距離。哈勃本人在1929年給出第一個數值： h
