On 29th July 2022, the Earth broke its record for the shortest day. It complete rotating on its axis 1.50 milliseconds, little over one thousandth of a second earlier than 24 hours.
This means is not the only time it has quick its pace.
The planet complete a full spin on 29th June 2022, in a time that was 1.59 milliseconds shorter than its standard 24 hour period.
The Earth has rotating faster, report Independent.
Year 2020 saw Earth create the month that has ever measure since 1960s.
The shortest day of all time that year was 19th July 2020.
It was 1.47 milliseconds under 24 hours.
In 2021, Earth continue to spin at a increase rate, it did not break records.
When you look at over much longer periods then it appears that Earth’s spin is slowing.
Every century, the planet takes a couple of milliseconds longer to complete one rotation, the publication reports.
But the causes of this are uncertain, scientists speculate that it could be because of processes in the inner or outer layers of the core, oceans, tides, or even climate change.
Some researchers also suggest that the increase pace of rotation and short days could be relate to the Chandler wobble, a small deviation in the Earth’s axis of rotation.
Scientists Leonid Zotov, Christian Bizouard, and Nikolay Sidorenkov who are schedule to present at the Asia Oceania Geosciences Society next week, Said :
“This is similar to the quiver one sees when a spinning top starts gaining momentum or slows down,”.
If the Earth continues to rotate at an increasing rate it could lead to the introduction of the negative leap second to keep the rate that the Earth orbits the Sun consistent with the measurement from atomic clocks, as per reports.
But, the negative leap second could potentially create issues for IT systems. In a recently-publish blog that said the leap second “mainly benefits scientists and astronomers”, Meta stated that it is a “risky practice that does more harm than good”.
This is because the clock progresses from 23:59:59 to 23:59:60 before resetting to 00:00:00.
A time jump like this can crash programmes or corrupts data due to the timestamps on the data storage.
Meta also said that should a negative leap second occur, the clock will change from 23:59:58 to 00:00:00 and this could have a “devastating effect on the software relying on timers or schedulers.”
