China’s Three Gorges Dam Is Slowing Down Earth’s Rotation – NASA Confirms

Did you know a man-made structure in China is altering the way our planet spins? According to a fascinating discovery by NASA, the Three Gorges Dam, the world’s largest hydroelectric power station, has actually slowed down Earth’s rotation — by 0.06 microseconds per day!

By holding back a staggering 40 billion cubic meters of water, the dam shifted Earth’s mass enough to subtly impact the planet’s rotation and axial tilt. While this change is incredibly small, it’s a mind-blowing demonstration of how human engineering can affect global-scale systems — even the physics of our own planet.

Located on the Yangtze River, the dam was primarily built for flood control and power generation, but it has also stirred scientific debate. This gravitational redistribution affects not just the spin, but potentially the Earth’s moment of inertia, similar to how figure skaters slow their spin by extending their arms.

NASA scientists used complex geophysical models to calculate the impact of the dam, showcasing how much influence massive infrastructure projects can have on Earth’s geodynamics. Though the impact isn’t dangerous, it’s a stark reminder of our footprint on the planet — even in unexpected ways.

Could future megastructures make even bigger changes? Are we unknowingly shaping the planet beyond climate change? Drop your thoughts in the comments and don’t forget to like and subscribe for more mind-blowing science revelations!
