On June 29, 2022, Earth recorded its shortest day since atomic clocks began measuring its rate of rotation. This comes from a report on the website. time and date outside. According to this, the earth rotated 1.59 milliseconds less than 24 hours. One millisecond is equal to 0.001 seconds. The last speed record on land was recorded in 2020.
According to the report, the Earth’s rotation is slowing down over long periods of time. For every century in the atomic clock era, the Earth took a few milliseconds longer to rotate on its axis. However, within these periods, the Earth’s rotation rate fluctuates.
Do the poles of the earth wobble?
Why does the earth spin faster? Scientists speculate that the reduction in day length is related to processes in the inner or outer layers of the earth, the oceans, the tides, or even the heated related. That is not safe. In addition, forecasts of more than a year in advance regarding the length of the day are hardly possible today.
According to TimeandDate, geoscientists plan to come up with a theory to explain the current shortening of day length this week. Therefore, the fact that the Earth rotates faster could be related to the so-called Chandler wobble. The Chandler wobble is a small random movement of the Earth’s geographic poles across the Earth’s surface, they say.
What will happen if the rapid rotation of the earth stops? Possibly the first negative leap second should be entered. That would mean clocks based on atomic clocks would have to skip a second. That, in turn, could lead to IT problems, the report says. According to scientist Leonid Zotov, the chances of an even faster rotation are 30:70.
