地球人测量恒星距离是以哈勃望远镜测量的恒星的亮度分析得出的结果，但是目前科学界普遍的认为宇宙有暗物质并且有巨大的暗能量，如果说光是正数暗物质像是负数其正负相加是一个什么数我们不知道!
earth's measurements of star distances are the result of an analysis of the brightness of stars measured by the hubble telescope， but there is now widespread scientific belief that the universe has dark matter and vast dark energy.if light is a positive number and dark matter is a negative number， we don't know what the positive and negative sum is!m.
