From this date, a day on Earth will last 25 hours.

We were always taught this at school there are 24 hours in a daythat is, the time it takes for planet Earth to rotate around itself. More precisely, now it lasts one day 23 hours 56 minutes and 4 secondsalthough they may vary depending on seasonality. This rotational motion of the Earth has changed over the 4.543 billion years since its existence. This causes the length of days to change and is actually still happening right now, moving away from the 24-hour format we currently know. In this sense, a group of scientists published a study showing that due to these differences, it is expected that Earth will eventually have 25-hour days

The Earth rotates around its axis passing through the North and South Poles (rotational motion) and around the Sun (translational motion). Thus, thanks to this rotational movement, there are day and night, and thanks to movement, the seasons of spring, summer, autumn and winter exist.

But why is the movement and rotation of the Earth slowing down? First, Days on Earth are lengthening very slowly due to the gravitational interaction of the Earth, Moon and Sun.. This phenomenon is known as slowing down of the Earth’s rotation. The Moon’s gravity causes tides on Earth, and friction between ocean tides and the seafloor slows the Earth’s rotation. As a result, Days are getting longer by about 1.7 milliseconds every century.

Why will there be 25-hour days on Earth?

When the Earth formed approximately 4.5 billion years ago, a day lasted about 6 hours. During the formation of our satellite the Moon, the rotation of the Earth slowed down due to gravitational forces (Law of Gravity).

Astrophysicist Norman Murrayin his paper entitled “Why a Day Lasts 24 Hours: The History of Earth’s Atmospheric Heat Tide, Its Composition, and Average Temperature (Earth’s Mean Temperature”), published in the journal Sciences Advances, explains the evolution of days. . If between 2600 and 2000 million years ago the length of a day on Earth was only 19.5 hours and it is lengthening, it means that over the years the day will last 25 hours.

It won’t be tomorrow or next year. As we have already said, every century a day on Earth lengthens by 1.7 milliseconds. This process is so gradual that on the scale of human life it is invisible to humans.

ABOUT When the Earth is 25 hours old, it is estimated that approximately 200 million years will have passedassuming that there are no other significant changes in the dynamics of the Earth-Moon system. Therefore, this change will not affect current and many future generations.
