...tory)观测的38个星系团中的其中6个,距离地球在140∼930万光年之内;钱卓利用这些星系团来帮助确认哈柏常数(Hubble constant)的数值。哈柏常数与宇宙的膨胀速率非常相关,可利用哈柏定律(Hubble's law):星系团远离的速度除以距离而得。

N the rate at which the expansion velocity of the universe depends on distance away. It is currently estimated to lie in the range 60–80 km s–1 megaparsec–1 哈勃常数 (Also called Hubble parameter)
The most widely accepted value for the Hubble constant right now is 72 kilometers per second per megaparsec, obtained by the Hubble Space Telescope.
目前哈勃常数最被广泛认可的值是每秒每百万秒差距72千米,这个值是由哈勃空间望远镜测出的。
H0 is the Hubble constant, or parameter that indicates the rate at which the universe is expanding; and distance is the galaxy's distance from the one with which it's being compared.
其中,速度表示星系后退的速度,H0为哈勃常数,也即宇宙膨胀速率的参数,而距离指的是星系与相比较星系之间的距离。
But nobody was ever sent to prison for espousing the wrong value for the Hubble constant. There is always room for more data to argue over.
但是,没有人因为坚持了错误的哈勃常数而被送进监狱,永远都允许建立在数据之上的讨论。
