These two summer days will be shorter than the others, the land impacted by an amazing phenomenon

On these two dates approaching, the duration of the day will be shorter. In addition, Scientists try to explain why. For example,

Rather, we are used to hearing that in summer the days are longer because the sun sets later. However, On June 21, the date of the summer solstice, was the longest day of the year. However, we should expect to know shorter days in the coming weeks. Similarly, The explanation is in the rotation of the earth. For example, A day corresponds to a complete rotation of the earth on itself, ie 24 hours or 86,400 seconds. Nevertheless, This duration can however be influenced these two summer days will new by different these two summer days will elements.

It is the position of the moon which seems, this time, influencing the rotation of the earth. To these two summer dates. it will be in its position furthest from the Ecuador. modifying its gravitational impact on the earth and then accelerating its rotation. The dates concerned are Tuesdays July 22 and August 5.

Rest assured, you will not realize this discrepancy. It will be an advancement of 1.38 millisecond on the first date and 1.51 millisecond during the second, measured thanks to very precise atomic clocks. Not even time to blink, since this action lasts about 100 milliseconds. For this difference to be noticeable, it would have to exceed 900 milliseconds in one day. However, it could play slightly on GPS navigation, computer networks or financial systems these two summer days will new where each millisecond can count.

However, this is not the first time these two summer days will that such an event has occurred. In 2024, the shortest day was faster by 1.66 millisecond. This acceleration is. in fact. noted since 2020, according to the statements of the international service of the rotation of the earth and the reference systems (ISRS) and would therefore not only be due to the placement of the Moon. “No one expected this. Most scientists believe that this is an internal phenomenon of the earth because the oceanic. atmospheric models do not explain this considerable acceleration. ” said Leonid Zotov, specialist in land rotation at the Moscow State University with Timeanddate.

This variation is closely monitored, but according to the expert, the earth will eventually decelerate. Other events can suddenly influence the speed of rotation of the earth. such as some important earthquakes or the these two summer days will new melting of ice. One solution exists in the face of this acceleration: the second interlayer. It allows you these two summer days will to align universal time on the real rotation of the earth. The next one could be added in 2029 if this scheme persists.
