Chinese mega-dam changed Earth's rotation: sensational statement by NASA scientist
This is reported by TUT.AZ with reference to telegraf.news.
China's grandiose engineering project - the Three Gorges Dam - has not only transformed the country's energy landscape but has literally affected our planet's movement. Dr. Benjamin Fong Chao, a leading NASA geophysicist, discovered that the colossal volume of 40 cubic kilometers of water, raised to a height of 175 meters, redistributed Earth's mass enough to slow down its rotation. As a result, the day became longer by 0.06 microseconds, and the Earth's axis shifted by approximately 2 centimeters.
"When you move mass - you change the planet's rotation. The effect is minimal, but measurable," explains Chao, drawing a clear analogy with a figure skater who slows down rotation by spreading their arms out to the sides.
The Three Gorges Dam, towering over the Yangtze River in Hubei Province, was fully commissioned in 2012. Its impressive dimensions - 2,335 meters in length and 185 meters in height - make it a true marvel of engineering thought.
However, scientists note that human activity is only a small part of the factors affecting our planet's rotation. Earth has been naturally slowing down since its birth 4.5 billion years ago. The main "brake" is the Moon, which through its gravitational influence is gradually moving away and slowing Earth's rotation.
Research paints an amazing picture of the past: about 1.4 billion years ago, Earth's day lasted only 18 hours, and over the past 70 million years, it has increased by a whole half hour. Modern calculations show that the length of the day is increasing by 1.8 milliseconds every century.
This gradual slowdown may have played a decisive role in the development of life on Earth. According to microbiologist Gregory Dick from the University of Michigan, the increase in daylight created ideal conditions for photosynthesizing bacteria, which saturated the atmosphere with oxygen and paved the way for the evolution of more complex life forms.
