Earth is rotating slow due to China

[indian_foxhound]

I don't think my clock is going to adjust for that!!!

BTW, does this have an effect on the clock/time coordination b/w space station and other space bodies and the Earth stations?

As per the explanation by @narcon might be...
Wat you think @narcon @1ndy

Yes, your sister is pregnant just because I looked at her.

Idiots!

Its zero point zero six microseconds, so everything is safe. But not sure about this, because i need supercomputer for such calculations: ATOMIC CLOCK.

Colours and bubbles, next time some one will say earth is squeezing because China importing Oil & Gas more than any.

China is not to be blamed here! Big skyscrapers in NY and Dubai, dense forests, Tide in ocean also increase Second moment of Area (Inertia)

And 0.06 micro seconds is 0.00000006 seconds. It means after every 60,000,000 (60 million) seconds earth will take 1 second more then it used to before to travel same distance?

There are 31,536,000 seconds in one year. So this would mean after almost 2 YEARS, earth will take 1 second longer to rotate! That's negligible! Even world's most expensive watches (Rolex and so on) which can tell time precisely till 10,000,000 seconds is not going to tell the difference!

Stop blaming everything on China! If anything you should be glad that China is doing its' bit for environment and "Green energy"!!

I thought it was a joke after reading the title of this post.
Next time they will blame china why man has balls.

Yes, the Earth will slow down a bit due to the dam - probably enough to warrant adding a leap second in the next few years.

The moment-of-inertia increase is probably the easiest geophysical change to calculate, one can do it with pen-and-paper. The polar motion and precession effects are more difficult to calculate. Unknown is the effect all that water will have on China's continental plates, though I suppose that an increase in nearby geothermal, earthquake, and volcanic activity may occur in the next few years.

0.06 micro second = 0.00000006 second.

if every rotation slows 0.00000006 second,
1 year = 365 days or 365 rotations


assume everyone lives for 100 years

100 years = 36525 rotations
36525 x 0.00000006 = 0.0021915 second

total time in 100 years, it runs 0.0021915 second slower


CONGRATULATION TO EVERY ONE,


because of the Chinese dam,
you live apparently 0.0021915 second longer.

How can something built from earth material over it's surface (earth) slow down it's rotation? How about those giant mountains and skyscrapers?

 

[theone-neo]

now earth cant even take weight of three chinese dams

us got one more reason to attack china lol

 

[Marshmallow]

is dis a joke or wat?

Three gorges dam is one single dam idiot not three separate dams! Learn to use you brain.

The Myth: The filling of the reservoir behind Three Gorges Dam in China changed the rotation of the Earth.

The Evidence: Three Gorges Dam, China crosses the Yangtze River in Hubei province, China. It the world’s largest hydroelectric power station by total capacity, which will be 22,500 MW when completed. When the water level is maximum at 175 meters (574 ft) over sea level (91 meters (299 ft) above river level), the reservoir created by the dam is about 660 kilometers (410 mi) in length and 1.12 kilometers (0.70 mi) in width on average. The total surface area of the reservoir is 1045 km2, and it will will flood a total area of 632 km2 of land. The reservoir will contain about 39.3 cu km (9.43 cubic miles) of water. That water will weigh more than 39 trillion kilograms (42 billion tons).

A shift in a mass of that size would affect the rotation of the Earth due to a phenomena known as the moment of inertia, which is the inertia of a rigid rotating body with respect to its rotation. The moment of inertia of an object about a given axis describes how difficult it is to change its angular motion about that axis. The longer the distance of a mass to its axis of rotation, the slower it will spin. You may not know it, but you see examples of this in everyday life. For example, a figure skater attempting to spin faster will draw her arms tight to her bodies, and thereby reduce her moment of inertia. Similarly, a diver attempting to somersault faster will bring his body into a tucked position.

Raising 39 trillion kilograms of water 175 meters above sea level will increase the Earth's moment of inertia and thus slow its rotation. However, the effect would extremely small. NASA scientists calculated that shift of such as mass would increase the length of day by only 0.06 microseconds and make the Earth only very slightly more round in the middle and flat on the top. It would shift the pole position by about two centimeters (0.8 inch). Note that a shift in any object's mass on the Earth relative to its axis of rotation will change its moment of inertia, although most shifts are too small to be measured (but they can be calculated).

The Verdict: True.

i cant believe dams are causin da earth to run slow

There gorges dam is one single dam idiot not three separate dams! Learn to use you brain.

k i dnt see it properly noob...dnt cry now
