Scientists confused, Earth spins faster than usual

Scientists were astonished to learn that the Earth was spinning faster than usual, making the days shorter than usual.

New measurements from the UK’s National Physical Laboratory show that the Earth is spinning faster than it was half a century ago.

On June 29, Earth’s full rotation took 1.59 milliseconds in less than 24 hours, the shortest day ever.

Scientists warn that if rotational speeds continue to increase, we may need to remove a second from our atomic clocks.

“If Earth’s rapid rotation continues, this first negative jump could be the start of a second,” astrophysicist Graham Jones reports via TimeandDate.com. New York PostTuesday (2/8/2022).

This would be necessary to keep civil time in line with solar time, which is based on the movement of the Sun in the sky.

A negative leap second means that our clock is over one second, which can potentially cause problems for IT systems.

META researchers say the second leap will have a huge impact on the technology and will become a “major source of pain” for hardware infrastructure.

“The effect of a negative leap second has never been extensively tested; it can have ill effects on software that relies on timers or schedulers,” wrote a blog on the subject by researchers Oleg Oblukhov and Ahmed Bygovi. Post claims.

Scientists Leonid Zotov, Christian Bijord and Nikolay Sidorenkov claim that the irregular rotation is the result of something called the Chandler wobble, which is the irregular movement of the Earth’s geographic poles across the surface of the globe.

“The typical amplitude of the Chandler wobble is about 3 meters to 4 meters on the Earth’s surface,” said Jotov. time and dateBut from 2017 to 2020 it disappeared.

Some experts believe that the melting and re-freezing of ice sheets on the world’s highest mountains may be contributing to the erratic motion.
