According to hubble s law , they are also very far from us 再根据哈勃定律推算,它们的距离是非常遥远的。
Hubble s law 哈勃定律
With hubble s law being put forward , the idea of the expansion of the universe is gradually established 就是哈勃常数。随著哈勃定律的提出,宇宙膨
The mass between us and virgo tends to decelerate the recession of our galaxy , as expected according to hubble ' s law by about ten percent 我们和室女座之间质量趋于减慢我们银河后退,如预期的依照大约百分之十的哈勃定律那样。
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 美国天文学家哈勃于1929年发现星系退行速度与其距离存在著正比的关系,即所谓哈勃定律:退行速度v h
