The atomic wall reveals that the rotation of the earth varies in speed – and we are entering very fast days.
When you say, “Oh, it’s gone one day faster,” there may be times when you are more right than you think. The speed of the Earth’s equatorial plane is 1,674.4 kilometers per hour, or 465.10 meters per second. A rotation of 86,400 seconds gives 24 hours, but sometimes the rotational speed increases, which shortens the day. It writes Time and date.
Many factors are thought to cause the planet’s rotation speed to change, not only occurring in the partially melted core, but also operating the oceans and our atmosphere. With accurate atomic clocks, it was possible to reveal just how big and regular these variations are.
It turns out that in 2020 the pace will be extraordinarily high. July 5, 2005 was a major landmark in the near future. It was 1.0516 milliseconds less than the 86,400 seconds set that day, the lowest day since 1973. But the strike in 2020 was less than 28 speed records, completing the best day on July 19 at 1.4602 milliseconds.
Researchers predict that 2021 will be even faster and shorter. They predict that the average day will be 0.05 milliseconds per 86,400 seconds – and the time lost throughout the year should be 19 milliseconds.
If true, 2021 will be the lowest year in decades. Not a single day of the year reaches 86,400 seconds in 1937.
