Though physicists can describe the universe's expansion in a few lines, the basic properties of life on Earth are far harder to quantify.
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。
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.
科学家们通过研究那些超新星去测量宇宙膨胀随时间的变化。
They were using these supernovae to measure how the universe's expansion is changing with time.
如果说暗物质真的存在,那将最终导致宇宙膨胀速度的加快。
