@dailymail: NASA has confirmed that China’s Three Gorges Dam has slowed Earth’s rotation, increasing the length of a day by 0.06 microseconds. Dr. Benjamin Fong Chao of NASA’s Goddard Space Flight Center says the shift is due to the enormous volume of water—about 10 trillion gallons—stored in the dam’s reservoir, located 175 meters above sea level. By redistributing this mass, the dam has subtly altered Earth’s moment of inertia, similar to how a spinning figure skater slows down when extending their arms. While the effect is incredibly small—adding just over three extra days across the age of the universe—it’s a striking example of how human engineering can influence the planet’s rotation. #news #china #nasa #space
