NASA Confirms China's Three Gorges Dam Slows Earth's Rotation

NASA scientists have confirmed that the Three Gorges Dam in China, the world's largest hydropower plant, has caused the Earth’s rotation to slow by a staggering 0.06 microseconds per day. This change is due to the dam's enormous water reservoir, impacting Earth's moment of inertia, akin to a figure skater extending their arms. While the effect on daily life is minimal, the implications on global geophysics and geopolitics are substantial, sparking scientific curiosity and environmental concerns.

China's Three Gorges Dam: Earth's Unexpected Brake

NASA reveals that China's monumental Three Gorges Dam is subtly slowing Earth's rotation, shifting its axis by about 2 centimeters and adding 0.06 microseconds to the length of a day. This intriguing effect highlights humanity's capacity to influence the very dynamics of our planet, despite the changes being too minute to impact everyday life. Through the principle of angular momentum, this dam underscores the vast implications of large-scale constructions on Earth's physical properties.
