Immigration cooling-off period

According to NASA, although it seems that the moon has almost stopped moving now, there has been a lot of movement on the moon in recent decades. On May 14, scientists measured an earthquake of magnitude 5 on the moon through instruments. This is not the first time for the moon. After man successfully landed on the moon, American astronauts installed five seismometers on the moon. According to the data, we know that during the eight years from 1969 to 1977, the number of earthquakes on the moon reached 28.

In order to find out the cause of the lunar earthquake, scientists have been focusing on the study of the geological structure of the moon for decades. Recently, in the analysis of more than 12000 images of the moon, scientists unexpectedly came to the conclusion that it seems that the moon has been shrinking in recent hundreds of millions of years, and this guess was later confirmed. Scientists say that in these hundreds of millions of years, the moon has lost about 150 feet, and the vibration of the moon is also caused by the contraction of the moon.

Scientists say that many cracks have appeared in the moon's shell, which is caused by the continuous contraction of the moon. Hundreds of millions of years ago, the moon was not as cold as it is now. On the contrary, the moon, like the earth, also reflects a lot of heat inside. However, with the exhaustion of energy inside the moon, the inside of the moon gradually cools down, and its shell will shrink based on the internal changes, just like grapes will shrink when they lose water. But unlike the surface of grapes, the moon will break like an egg shell because of the serious loss of water in the crust, so we can often see many reverse faults on the moon, that is, the surface of the moon we see? Fold? Part.

This news is another news that worries many people after the news that the moon is moving away from the moon. Many people think that in the future, we will not be able to see the moon from the sky. Scientists say that we don't have to worry about this at all. This is just an inevitable process of the evolution of the earth's life cycle. Not only the moon, but also other planets, such as mercury. What do we see on its surface? Fold? It is bigger than the moon, which means that mercury contracts faster than the moon.

In addition, some people worry that the shrinking of the moon will have a bad influence on the earth's climate. After all, not only the earth is locked on the moon, but also the moon touches the earth in the tidal locking. Scientists also said that even if the radius of the moon is shrinking, its total mass is basically unchanged, so we don't have to worry that the shrinking of the moon will have a bad influence on the earth, or even that the moon will disappear.

However, we should guard against the earthquake caused by the contraction of the moon in advance. After all, at the current speed of human science and technology development, it is an inevitable trend to immigrate to the moon in the future. Moreover, the establishment of a base on the moon in the early stage of human beings is doomed to deal with the environment on the moon. If prevention is not carried out in advance, there will be no small obstacles for human beings to establish bases on the moon in the future, and even casualties may occur.
