Summary:
- NASA has confirmed that the construction of a massive dam in China has shifted the Earth's axis by a small but measurable amount.
- This shift in the Earth's axis has resulted in slightly shorter days, with each day now being about 0.2 milliseconds shorter than before the dam was built.
- The change in the Earth's axis is a testament to the incredible power of human engineering and the impact we can have on our planet, even at a global scale.
