Planet Earth records the shortest day ever


29/07 19:06

The globe has completed a full rotation around itself, which should take 24 hours, in a period of less than 1.59 milliseconds, due to the increasing speed with which the Earth rotates around itself in recent times. According to “Sputnik”, the Earth recorded the first shortest day ever measured since the 1960s, in 2020, when it revolved around itself by about 1.47 milliseconds in less than 24 hours. The Earth continued to accelerate during the year 2021, but without records, prior to recording this year’s records initially referred to, however, the Earth’s cycle appears to be slowing down in the long term, as it is still a few thousandths of a second takes to complete each century, according to Monte Carlo report. The reason behind this phenomenon is not clear to scientists, but they believe that it may be due to changes in the inner or outer layers of the planet or in the oceans, or perhaps to tidal factors or climate changes. But what does that mean? If the Earth continues its acceleration, it could lead to the adoption of what is known as the “negative leap second”, with the aim of keeping the rate at which the Earth orbits the sun in accordance with the measurement of atomic -hours. But this “leap second”, a potentially negative or positive adjustment of one second to the UTC time scale depending on the Earth’s rotation, could cause problems for IT systems, and major technology companies have already warned that the move is “risky and do more harm than good.” “. What will happen is that the day will be one second lower before the time is reset to 00:00:00. This can lead to software failure or data corruption due to timestamps related to data storage. It is worth noting that the Coordinated Universal Time, which is the basic time standard by which the world regulates clocks and time, has been updated by a leap second 27 times so far, the last of which was in 2016. Also due to the instability of the Earth’s rotation speed, scientists have the atomic clock invented in 1950, of For accurate tracking of time, but due to the irregularity of the Earth’s rotation, either in terms of acceleration or deceleration, and in light of the constant timing of the atomic clock, it became clear that there ‘ There is a difference between the atomic clock and astronomical time, which is calculated according to the Earth’s rotation. osion and astronomical time, scientists devised the Coordinated Universal Time “UTC” to help reduce the difference between Earth time and the atomic clock. timing of the Earth’s rotation and the atomic clock in agreement with each other.
