In 2022 recorded the shortest day of all time. That’s why the Earth accelerated its rotation and June 29 was the shortest on record

Why did planet Earth accelerate its rotation and June 29, 2022 was the shortest on record ? The previous record was documented on July 19, 2020 , when the day measured 1.47 milliseconds shorter than normal. In 2022 , experts confirmed the registration of a new historical record:

A report released on July 27, 2022 by the Norwegian time zone monitoring website timeanddate.com claims that the Earth completed a rotation on June 29, 2022 in 1.59 milliseconds in less than 24 hours . Our planet’s rotation was measured in 1.59 milliseconds less than the normal 24-hour day of June 29 , according to the International Earth Rotation and Reference Systems Service , an organization responsible for measuring global time. A rotation of the earth, we remember, isthe time it takes for the Earth to turn once on its axis , which is approximately86,400 seconds . But why is this strange slowdown intensifying more and more often in the space of just a few years? The phenomenon would enjoy a credible scientific explanation:

In 2016, a study by astronomers at the  Royal Observatory in Greenwich  revealed that, overall, the Earth’s rotation has slowed by about 6 hours in the previous 2,740 years. According to the  research , the average of a 24-hour day stretched by about 1.78 milliseconds over the course of a century. The accelerated rotation is disconcerting to scientists in the field, as the Earth has actually begun to change its rotation since its ancient formation , which occurred about 4.5 billion years ago . In fact, a leap second has been added to the TAI 27 times since 1972. . “Chandler’s wobble is a component of the instantaneous motion of the earth’s axis of rotation, the so-called polar motion. , which changes the position of the point on the globe where the axis intersects the earth’s surface, “ explained Dr.of the Sternberg Astronomical Institute . “The normal amplitude of the oscillation is about four meters on the earth’s surface, but from 2017 to 2020 it disappeared.” Professor Matt King is the director of the Australian Center for Excellence in Antarctic Science (ACEAS) and a professor at stated that the phenomenon: School of Geography, Planning, and Spatial Sciences at the University of Tasmania .

“It’s certainly strange. Clearly something has changed , and it has changed in a way that we haven’t seen since the beginning of precise radio astronomy in the 1970s,” said Professor King at the Australian Broadcasting Corporation . ” When you start looking at the real thing. crux of the matter, you realize that the Earth is not just a solid ball that turns, “ astronomer Fred Watson added to ABC.  ” It has liquid inside, it has liquid on the outside, it has an atmosphere and all these things flutter a little. “

You probably haven’t even noticed that you missed those 1.6 milliseconds, but for some people they are important. The International Earth Rotation and Reference System Servic and has occasionally added leap seconds to keep the clocks in line with the slowing of Earth’s rotation.
