London: Scientists say that with the speed of the earth rotating, it is not yet possible to say that every day is 24 hours old. The land rotation has accelerated in the last 50 years. According to a report in the British media Daily Mail, it is not necessary to complete 24 hours a day from 2020. The same year, on July 19, was the shortest time since the 1960s.
Don't mistake it for a significant decrease when you hear that it's less. The same day was less than 24 hours, 1.4602 milliseconds. In some earlier estimates, the earth also has a history of completing the day with more than 24 hours.
The International Earth's And Reference Systems Service (IERS) decided in December 2020 that it would not add any additional leap seconds to accurately the world's official time, although it is not clear whether the new discovery was considered. Leap seconds are set to keep time as accurate as the year of a leap.
According to a 2015 study, global warming could accelerate the earth's rotation. According to an article published by Science Advances, melting glaciers or glaciers and reaching the sea as water can speed up the earth's rotation.
The scientific explanation is that the average half-second sec in 24 hours is less than the new one. The new discovery has also initiated new discussions on setting time in the scientific world. The fastest 28 days since the 1960s occurred in 2020. One of the discussions was whether to keep a second off time so that it could get more compatible with the rotation of the earth.
