Earth is spinning faster than usual


While the clocks in our phones indicate there are exactly 24 hours in a day, the actual time it takes for Earth to complete a single rotation can vary. And there are usual and unusual facts in this matter. Scientists discovered the Earth is spinning faster. On July 26, 2022 our planet finished its day 1.50 milliseconds shorter than usual. There are some theories about why it’s happening and what impact it may have on our lives. Even melting of ice caps moves matter around on Earth and thus can change the rate of spin. The connection between Earth’s interior and surface comes into play too. Even earthquakes and storm events can play a role. “The rotation rate of Earth is a complicated business. It has to do with exchange of angular momentum between Earth and the atmosphere and the effects of the ocean and the effect of the moon,” Judah Levine, a physicist in the time and frequency division of the National Institute of Standards and Technology declared.


“Clearly something has changed, and changed in a way we haven’t seen since the beginning of precise radio astronomy in the 1970s,” Matt King from University of Tasmania said. Precisely understanding Earth’s rotation rate is crucial for a host of applications – navigation systems such as GPS wouldn’t work without it.Some scientists have called for the introduction of a negative “leap second,” which would subtract one second from a day to keep the world on track for the atomic time system.
