Why is the Earth spinning faster than usual?
Amid all the hustle and bustle of modern life, time may seem to “fly” more often, but it turns out that it really is, following the Earth recorded its shortest day since recording began in June, and raises 1.59 milliseconds of the usual 24-hour rotation on June 29 the possibility A negative leap second has occurred to maintain clock alignment, the first time in history that world clocks have been accelerated. Scientists claim that climate change, seismic activity and ocean circulation might be responsible, as might be the lunar pull and the so-called “Chandler and Bobble”; It is a phenomenon defined as the oscillating motion that occurs when the Earth rotates on its axis.
Climate change:
Global warming is also considered to be having an effect by melting ice and snow at a faster pace, and research has suggested that as glaciers melt, as a result of higher atmospheric temperatures from the combustion of fossil fuels, the redistribution of mass causes the Earth to spin and spin faster on its axis, and this leads to a loss of Hundreds of billions of tons of ice annually enter the oceans, causing the north and south poles to move eastward since the mid-1990s. The location of the poles moved 13 feet (4 meters). The Earth’s rotation axis, an imaginary line that passes through the north and south poles, always moves due to processes that scientists do not fully understand, but the way in which water is distributed on the Earth’s surface is one of the factors that lead to the shift of the axis and thus the poles, and one example of this is the decrease in mass The Greenland glacier has warmed throughout the 20th century, and in fact regarding 7,500 gigatons of Greenland ice melted into the ocean during this time period, making it one of the most important contributors to mass transfer to the oceans, causing sea levels to rise.
seismic activity:
Earthquakes and other seismic activities can have an effect on the speed of our planet’s rotation, and this is also because they can move mass toward the center of the Earth, like a spinning person pulling their arms inward, thus shifting their weight once more. For example, the 2004 earthquake that unleashed a tsunami in the Indian Ocean shifted enough rock to shorten the length of the day by regarding three microseconds: major earthquakes in Chile in 2010 and Japan in 2011 increased the Earth’s rotation and thus shortened the length of the day.
ocean circulation:
The rotation of the ocean and pressure on the sea floor is also pulling the Earth’s axis, and in November 2009 events in the Southern Ocean made the Earth spin a little faster, shortening half of the days of the month by 0.1 milliseconds each. On the continent, the Antarctic Current surrounding the poles is the cause. Experts at NASA’s Jet Propulsion Laboratory (JPL) in Calif By 0.1 milliseconds, before the length of the day returned to normal on November 20 of that year in line with the current.
Mystery in the Earth’s core:
Some experts believe that the explanation lies within the Earth itself, with the possibility of something happening in the core and mantle of the planet, and the speed of our planet’s rotation around its axis has varied throughout history, and 1.4 billion years ago, the day would pass in less than 19 hours, compared to 24 hours now, so, in On average, the Earth’s days are getting longer, not shorter, by regarding 74,000 parts of a second each year, but the planet is currently spinning faster than it was half a century ago, and sometimes the rotation speed varies slightly, which affects the global time adjuster, the atomic clock, which requires Adding leap seconds, or in the latter case, a negative leap second likely to occur, and a total of 27 leap seconds have been needed to maintain atomic time accuracy since the 1970s, most recently on New Year’s Eve 2016 when clocks paused for a second to allow Earth To catch up, but since 2020, this phenomenon has been reversed, the previous fastest day, on July 19 of that year, was 1.47 milliseconds shorter than 24 hours, and humans cannot detect the change, but it may affect satellites and navigation systems, and it consists every day On Earth from 86,400 seconds, but rotation is mine Q is regular, which means that over the course of a year, every day contains a fraction of a second more or less, and the atomic clock is very accurate.
Finally: The Messenger of God was right in his hadith that time has turned.
