50 means the universe is aged between 13 and 16 . 5 billion years old 50表示宇宙年介乎130到165亿年之间。
The universe is 13 . 7 billion years old with only a 1 percent margin of error 宇宙年是137亿岁,误差只有百分之一。
Was later revised to 70 10 in 1999 , which means the universe is aged between 9 and 12 billion years 是7010 ,相对于宇宙年90亿至120亿年。
What is the age of our universe and how does it compare to the average life span of a human being 原子核中子质子宇宙年有多大?和人类的年岁相比又相差多少?
80 17 through observation of the spiral galaxy m100 and thereby deducted that the universe was aged between 8 and 11 billions years old 8017 ,折算宇宙年大约在80亿至110亿年左右。
100 , then it indicates the age is between 6 . 5 and 8 . 5 billion years old . the actual age is determined by the density of matter in the universe 100 ,即表示宇宙年介乎65到85亿年之间,而实际数字则取决于宇宙的物质密度。
Is not only a parameter for measuring expansion of the universe , it can also be used to determine the age and the size of the universe , amount of dark matters , numbers of hadrons and abundance of light elements in the universe and even the structure of the early universe , and so forth 的一个参数,而且还可以用来计算宇宙年宇宙大小宇宙中黑暗物质的数量重子数目轻元素丰度甚至早期宇宙形成的结构等等。
