The shortest day in history may come, scientific warning
In a surprising discovery, scientists warn that the earth is now spinning faster than usual, according to the Daily Mail UK.
This situation is likely to cause the shortest day in history in just a few weeks.
A astrophysics from the University of London, Graham Jones, revealed that the rotation of the earth now shows the acceleration of contingents.
This is expected to cause a reduction in 1.30, 1.38 or 1.51 milliseconds in one of the three dates this summer, July 9, July 22 or August 5.
Although this change looks very small, researchers warn that it can affect important technological systems such as GPS, satellites and global measurements.
What happened on earth?
Since 2020, scientists have detected that the earth rotates a little faster than usual.
Before that, the earth was truly suffering from natural delay due to the gravitational pull of the moon, the factors that form the 24 -hour cycle that we practice today.
Usually, one full round of the earth takes the exact period of 86,400 at (24 hours).
However, the rotation of the earth is not always consistent, it can change a few milliseconds due to various natural factors.
Among them such as earthquakes, ocean currents, glasier disbursement, liquid metal movements in the earth’s terrace and large weather phenomena such as El Niño.
The shortest day ever recorded
The phenomenon of the rotation of the earth is not something new, but has been observed in recent years.
On July 5, 2024, the Earth recorded the fastest day in modern history, when one day was 1.66 milliseconds shorter than the 24 -hour standard period.
This is not the first time something like that has happened. Since 2020, researchers have recorded several similar incidents that show trends in increasing the speed of the earth.
This includes July 19, 2020 and July 9, 2021, each with a reduction in 1.47 milliseconds, respectively, on June 30, 2022, each, with a reduction in 1.59 milliseconds.
In 2023 seeing a little delinquency, but in 2024, the Earth accelerated and recorded a few days in a row, making it the most consistent year with rapid rotation in the history of modern measurements.
Why did that happen?
According to the Daily Mail UK, the true cause of this acceleration is still a mystery.
“No one expects this … and the cause is still unknown,” said scientist from Moscow State University, Leonid Zotov.
Researchers now focus on various elements that may be contributors. Among them are:
- Changes in liquid earth core and bent metal
- Ocean currents that eliminate the mass of this planet
- High height winds like Jet stream
- The balance of the physical form of the earth
Impact on the Modern World
Add Daily Mail UK, small changes in one millisecond can have a major impact on modern technology, including:
- GPS system accuracy
- Communication networks like cellphones
- International financial system that depends on microdetic time
At present, the world uses Universal Coordination Time (UTC) to coordinate time. Under normal circumstances, we added second jump To ensure time according to the movement of the earth.
However, if the earth continues to rotate faster, scientists may need to reduce one second, known as second jump Negative, something that has never been valid in human history.
What will happen?
Experts say that, in the long run, the earth will return slowly as usual.
But for now, this planet continues to show an increase in speed that can be explained by the atmosphere and existing marine models.
“Slowly, the earth will slow down,” said Zotov. But for now, scientists are still actively learning and waiting for their answers while the earth continues to accelerate, even with only a few milliseconds.
