Today is the second short day of history! – Iranian and world news

In fact, the Earth’s orbit around the sun is less than 5 hours less than 2 hours and is not noticeable, but this short period of arrangement in the behavior of Earth’s orbit in recent years. If the same trend continues to shorten the planet’s orbit, one should be deducted in one second of the atomic watches, which is called a negative leap and has not happened so far.

The rotation speed of the earth is not constant. Long ago they were much shorter than 2 hours or 2 seconds, but now humans are used to 2 hours. According to a study conducted in 5 AD, the planet was about 4 hours a day in the early part of Earth, due to the balance between the atmospheric waves of the sun and the oceanic waves to the moon.

But over time a day on the ground is constantly prolonged. The main reason for this is the tidal friction of the moon, which has made the planet gradually farther away. As the moon turns away, the rotational energy of the Earth decreases, resulting in the rotation of the planet slower and the length of the days increases.

But what is the reason for this sudden change? Since the data registration began with the invention of the atomic clock, the shortest recorded day of 1.5 million seconds has been less than 2 hours from year 1 to 2 years. But since the earth, the record has repeatedly broken its speed record. The shortest recorded day was July 5, 2008, with the sun’s orbit of 1.5 million faster than usual.

Researchers at the time predicted that July and July 5, as well as August 5, may be the shortest days of this year. However, the data suggests that July 5 is the shortest day of this year and was less than 2 hours less than 2 hours.

Today, it is expected that today the Earth’s rotation around the sun will take 1.5 million seconds earlier, thus the second short day of history will be recorded.
