hubble distance 中文意思是什麼
hubble distance
解釋
哈勃距離-
For the measured value of the hubble constant, this distance is about 14 billion light - years
由量測到的哈伯常數值來推斷，這個距離大約是140億光年遠。 -
If we know the value of the hubble s constant, we can determine the distance of a galaxy by means of hubble s law
例如上例中的星系，如果哈勃常數是60的話，它便距離地球150百萬秒差距。 -
The hubble space telescope captured the light variation of o e of the cepheids inside the spiral galaxy m100 which is at a distance of 56 million light years away from earth
距離地球五千六百萬光年的旋渦星系m100內，哈勃太空望遠鏡拍得當中一顆造父變星的光度變化 -
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 -
In fact, hubble ' s law predicts that galaxies beyond a certain distance, known as the hubble distance, recede faster than the speed of light
事實上哈伯定律預測，在某個距離以外的星系，後退的速度會比光速快，這個距離叫做哈伯距離。 -
It was through this method that a group of american astronomers worked out in 1998 the distance of some extremely remote galaxies. if we compare the distanced of these galaxies deduced from type ia supernovae with those from hubble s law, it will provide extremely valuable information for astronomers to verify the big bang theory
一九九八年，一群美國天文學家便是透過觀測ia型超新星來推算出一些極遙遠星系的距離，再對照這些星系光譜中的紅移程度，給我們的宇宙膨脹理論提供了全新的資料。 -
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：
