Our home galaxy has a new, super-precise mass measurement: about 890 billion times the mass of our sun. That's 3.9 tredecillion lbs. (1.8 tredecillion kilograms), a tredecillion being a 1 with 42 zeros after it, or 1,000,000, 000,000,000,000,000,000,000,000,000,000,000,000. That amounts to about 6 billion billion billion elephants, 296 quadrillion Earth masses or 135 times the mass of the supermassive black hole in the image released back in April.

说银河是1.8 x 10^42公斤, 相当于6x10^27大象,每头大象重3x10^14公斤重?还是我 哪里理解错了?

算上暗物质了吗
应该算上了,8900亿个太阳质量,太阳在全部恒星中除于90%左右的水平,而银河系全
部恒星数目,上限4000亿,下限1000亿。不算上暗物质没有8900亿

就这么点?那还是养不活广东人啊。
你看清了是六乘十亿乘十亿乘十亿,三个乘,不是三个加。这么多大象,吃到宇宙结束也吃不完
