Scientists have found that the earth’s rotation is slowing down, and it may be 1000 hours a day in the future

This paper takes part in the series essay competition of “great science” of Recordunkown.

The earth is the home where human beings have lived for millions of years. For this home, we know more and more about it in the long millions of years. If we want to really understand it, we have to go back to the age of science and technology.

As human beings enter the era of science and technology, with the help of science and technology out of the earth, we have a more intuitive understanding of the earth. At that time, we knew why the earth had day and night, why there were 24 hours a day, why there were 365 days a year. In fact, all this is related to the rotation and revolution of the earth.

Standing in space, we can intuitively see that the earth is rotating rapidly around the sun at the same time of rapid rotation. With the rotation and revolution of the earth, there are four seasons of the year, day and night, stable ecological environment, and the birth of the earth and human beings.

Compared with the earth’s relatively stable revolution, the earth’s rotation is greatly affected by various aspects. Through research, scientists have found that the earth’s rotation is not constant. Since the day it was born, the earth’s rotation speed has been slowing down. 543 million years ago, the earth’s daily time was only 0.37 hours, but now it is 23 hours, 56 minutes and 04 seconds.

From this we can see that it is very obvious that the speed of the earth’s rotation slows down. So what causes the earth’s rotation to slow down? In fact, to solve this mystery, we should start from the early solar system and the early birth of the earth.

The earth was born 4.6 billion years ago. In the early days of the earth’s formation, its speed was much faster than it is now. At that time, the solar system was very busy, with objects of various sizes all over the solar system, and collisions occurred every day. At that time, the earth was also hit by a large number of asteroids. Through these impacts, the speed and orbit of the earth’s rotation were constantly changing slightly.

However, asteroids are too small after all, and their impact on the earth’s rotation is limited. The impact that really had a great impact on the earth occurred in a planetary impact the size of Mars. If a planet collides with the earth head-on, the consequences will be unimaginable. It may make the earth collapse into several pieces, and there will be no present earth. So this time the planet hit the earth, it was just a side impact.

Although it was only a side impact, it was also very powerful. It directly knocked out a lot of material from the earth, which formed a planetary ring around the earth. There is a larger individual in the ring, which is the predecessor of the moon.

Because the mass of the moon is much higher than that of other debris, it gradually removes other materials from the planetary ring, and becomes larger and larger. Finally, the whole planetary ring is integrated and becomes the moon we see today. Because the mass of the moon is so great, its appearance has a huge impact on the operation of the earth.

The mass ratio of the moon to the earth is 1:81, which is a very rare phenomenon in astronomy. No known satellite can reach such a ratio with the planets it orbits. It is because the mass of the moon is too large, the gravity is also large, which has a very obvious drag effect on the rotation of the earth, thus forming a tidal lock between the earth and the moon.

This tidal lock constantly changes the earth’s rotation, so that the earth’s rotation speed slows down from the day the moon was formed, and the speed becomes more and more obvious until today. So the earth’s rotation speed will continue to slow down in the future. How slow will it be? According to the computer simulation, a general data is obtained. One day in the future, an earth day may reach 1000 hours, that is, more than 40 days in a day.

However, scientists say that although the main reasons for the slow rotation of the earth are tidal lock-in and tidal friction, other factors also exist. For example, after entering the era of science and technology, human beings began to launch various kinds of aircraft and artificial satellites into space. More and more of these man-made objects surround the earth’s orbit.

According to the principle of conservation of physical energy, the impact of these satellites on the earth’s rotation should also be one of the reasons for the slow rotation of the earth. Of course, the impact is relatively small, far less than the impact of the moon’s gravity.

Scientists are still actively studying and exploring the causes of the earth’s slow rotation. For most people, they are not concerned about the causes of the slow rotation of the earth, but about the impact of the slow rotation of the earth on the earth’s ecological environment and human beings. If one day the earth’s day becomes 1000 hours in the future, the time of day and night will be as long as more than 20 days, which is bound to have a great impact on the ecological environment and human beings.

If the speed of the earth’s rotation changes greatly, the work and rest time of human beings and animals will be disrupted, and some creatures will gradually weaken and die because they can’t adapt to the great changes. At that time, although the time of the earth’s rotation was still 360 degrees, the speed of the earth’s rotation slowed down a lot, which had a great impact on the time zone.

If one day turns into 1000 hours, it is also a big problem whether the current time zone calculation method can adapt to the survival and development of human beings. Perhaps at that time, human beings will re formulate new time zone standards to adapt to the new rotation of the earth. At the same time, the slow rotation of the earth will also affect the earth’s linear velocity, which is what we call the eccentricity.

When the centrifugal rate slows down, the sea water from low latitudes will flow to high latitudes, thus changing the ratio of sea area to land area, and finally the survival of some organisms will be affected. This change not only brings about the change of regional climate, but also changes the survival mode of marine and terrestrial organisms.

Of course, the impact of the earth’s slowing down is relatively large in the long term. However, the slowing down of the earth does not happen in a short time, but develops over a long period of time. Therefore, the time span will minimize the adverse effects. Even if the earth’s rotation speed becomes slower and slower in the future, the earth’s ecological environment will have enough time to adjust and change, and human beings will have enough time to adapt to this change.

In fact, in the billions of years since the birth of life, the earth’s ecological environment has undergone many major changes, which may have something to do with the slowing down of the earth’s rotation speed, but the earth’s ecological environment and life can adapt to this change through continuous evolution and evolution. It can be seen that the adjustment ability of the earth’s nature is very strong, and the slowing down of the earth’s rotation will not have any great impact on the ecological environment and human beings.
