The Earth's rotation is getting faster and the days are getting shorter
June 29, 2022 was revealed to be the shortest day since the 1960s when high-precision atomic clocks began measuring the rotation of the Earth. From this, it is shown that the rotation speed of the earth is accelerating in recent years.

According to The Guardian, the short-time record for one day has been updated one after another over the past few years. In 2020, it recorded the shortest 28 days in the past 50 years, and the shortest day, July 19th, was 86,400 seconds, or 1.47 milliseconds shorter than usual in 24 hours. rice field. Furthermore, on June 29, 2022, the day was 1.59 milliseconds shorter than usual on June 29, 2022, when this record was further broken and set as a new record.
The Earth is gradually accelerating, albeit slightly, but in the long run it is rather slowing down. When rewinding time to 1.4 billion years ago, long before the era when dinosaurs were active, there were only 19 hours a day. The Earth's rotation speed is gradually slowing down due to the friction between the seawater, the seabed, and the land shore due to the ebb and flow of the tide, and it has decelerated to the current speed of about 24 hours.
According to The Guardian, it is difficult to accurately predict the speed of the earth because the speed of rotation changes slightly due to fluctuations in the core of the earth, seawater on the ground, gas in the sky, etc. . In the past, strong winds caused by El Niño events
The Guardian wrote, 'How these different processes combine to affect the length of the day is still a problem for scientists.'
