The Earth is spinning faster than it was 50 years ago

The scientists were baffled after discovering that the Earth is spinning faster than normal what makes the days longer shorts usual. New measurements made by the National Physics Laboratory of the United Kingdom show that the Land is spinning faster than it does half century.

Land

The June 29, the complete rotation of the Earth took 1.59 milliseconds in less than 24 hours, the shortest day never registered. Scientists have warned that if Rotation speed continues to rise, we may need to remove a second of our atomic clocks. “If the rapid rotation of the Earth continues, it could lead to the introduction of the negative first jump second», reported the astrophysicist Graham Jones via TimeandDate.com.

“This would be necessary to keep Civil Time, which is based on the super-steady beating of atomic clocks, at the same rate as the sun time, which is based on the movement of the sun across the sky. A negative leap second would mean that our watches they skip a second, which could create problems for IT systems»Jones says.

The meta researchers They said that one second less would have colossal effects on the technology and it would become a “major source of pain” for hardware infrastructures. “The impact of a negative leap second has never been proven to big scale; could have a devastating effect in software that depends on timers or schedulers»stated an entry published by the researchers Oleg Obleukhov and Ahmad Byagowi.

Chandler Wobble Movement

The scientists Leonid Zotov, Christian Bizouard and Nikolay Sidorenkov state that the irregular rotations are the result of something called ChandlerWobble, an irregular movement of the geographic poles of the Earth along the surface of the balloon.

“The normal amplitude of the wobble of Chandler is about 3 to 4 meters in the surface from the earth”Zotov told Time&Date, “but from 2017 to 2020 He disappeared”. Some experts They believe that melting and refreeze of the polar ice caps on the world’s tallest mountains could be contributing to the irregular speed.

“Earth has recorded its shortest day ever since scientists began using atomic clocks to measure their Rotation speed. On June 29, 2022, the Land it completed a turn in 1.59 milliseconds in less than 24 hours. This is the last of a series of speed records to Earth from 2020″, reported Time&Date.

Zotov claims that there is a “70% chance” that him planet have already reached the minimum duration a day, which means we’ll probably never have to use a negative leap second. However, Zotov admitted that there is no way to know for sure with the Current technology.
