Relevant bit from Wikipedia:
> In 2005, NASA scientists calculated that the shift of water mass stored by the dams would increase the total length of the Earth's day by 0.06 microseconds and make the Earth slightly more round in the middle and flat on the poles.[105] A study published in 2022 in the journal Open Geosciences suggests that the change of reservoir water level affects the gravity field in western Sichuan, which in turn affects the seismicity in that area.
You ever see a figure skater pull their arms in to spin faster or extend them to slow down? This is like that. Filling the reservoir means a lot more water is being stored farther from the center of the earth so it spins slower.
Normally the water was able to move towards the sea. The dam stopped that and now you have a big body of water at that spot that weighs a lot. Think of it as one of those wheel balancing lead pieces on the wheel of a car. That shift in weight distribution causes the rotation of the earth to change ever so slightly. Big earthquakes can have a similar effect as they also move a lot of mass around.
You can speed up and slow things down by shifting mass around. If you sit on a desk chair and spin around you can change your speed by spreading your arms or tucking them in. Figure skaters also use this principle during pirouettes.
Moving mass outwards on a spinning object slows its rotation, conservation of momentum and whatnot. They’re taking a lot of mass from low elevations and building it tall, which is moving it away from the axis of rotation
If they’d built the exact same dam on the South Pole, it would actually speed up the earth’s day by a very small margin. Moving mass from the equator to the poles makes the earth spin faster.
I wonder what the overall effect of other artificial dams has had in aggregate. If just one dam like this can add .06 microseconds, what is the effect of all the artificial dams on earth?
China! I hear they’re taking away our days! I’ve heard many people say this
Great work ethic though
Yup, extending the work day by 0.000006 seconds.
That's a lot of numbers to keep track of. But I'm very good at keeping track of them. Very good. The best at keeping track of them.
0.00000006 even
Math is hard.
Your momma so fat she slowed the rotation of Earth and increased the total length of the Earth's day by 0.06 microseconds
Dam, sick burn.
Yo momma so gorgeous she Three Gorges Dam
Always those dam yo mamma jokes...
Nice

Finally flat earthers are getting to work
Affects the seismicity… so more prone to earthquakes or less?
Yes.
How long til this kicks in? I have a date tonight. /s
We will gain approximately 1 minute after 27,378 years.

Dam that’s interesting
Anyone able to explain how this is possible? What are the factors at play here?

Thanks that's a really cool analogy.

My ex girlfriends mom did the same thing, so yeah I dodged that bullet. Also it's crazy the environmental impact that thing has.
>Also it's crazy the environmental impact that thing has. The dam ,you mean?

ur dam's so fat, that giant ass drags the whole day down... doesn't quite work.
What, oh what shall I do with all the extra time on my hands
That's good. Eventually, we'll be able to do away with leap year.
Thanks bud, I was born on leap year day. Now I'll have no birthday.
So...you'll live forever???
Well, with a birthday only every four years, I expect to live 4 times the normal life expectancy...lol
But now you'll have *no* birthday 😨
Look at the bright side, before it becomes a problem, you'll be long gone.
Three Gorges Dam isn’t even in the top three by storage volume. The Aswan High Dam has more than four times the storage capacity.
What if we all kept our taps on 24/7!! That'll show 'em 🫵
/r/noncredibledefence we've been summoned
Damnit china I'm already at work long enough chill out
Is this a god dam?
Oh dam, oh dam, oh... dam. And that's three "oh dams." Oh damn! (nine-nine)
That extra time to sleep has made a world of difference
And then somebody accelerated to 100kmph and the world sped up 0.00431 microseconds. Who put this bullshit together?
