本来想说NASA不至于这么闲吧，搜了一下原来是台湾学者提出来的，那就不奇怪了。
Back in 2005, NASA scientist Dr Benjamin Fong Chao calculated that when that amount of mass is concentrated into one spot it is enough to affect the Earth’s rotation. That claim has recently been doing the rounds again on social media, but how much of an effect does the dam really have and why?
Well, Chao calculated that, when full, the dam could increase the length of the day by 0.06 microseconds. That’s 60 billionths of a second.
Chao also calculated that the dam can move the poles of the Earth by around two centimetres.
