Chang'e-4 discovered a huge "dark spot" on the back of the moon, which is made of material that does not belong to the moon!

Judging from the images transmitted back to the earth by Chang'e 4, the landforms on the back of the moon are more "ferocious" than those on the front.

It turns out that the back of the moon is covered with "scars" caused by impacts and collisions, that is, craters. These craters on the back of the moon vary in size, but are very densely distributed. This has brought considerable difficulties to the landing of Chang'e-4. In addition to a large number of craters, there are many mountains, canyons, and cliffs on the far side of the moon.

What is surprising is that in the images returned by Chang'e-4, scientists also discovered that there are huge "dark spots" on the back of the moon, but the material making up the dark spots does not belong to the moon.

Hawking ’s warning

In addition to uncovering the mystery of the landforms on the far side of the moon, Chang’e 4 also revealed the lunar “garbage” before human eyes.

This is because many countries have tried to detect the back of the moon before, but they all ended in failure, so those detectors were dormant on the surface of the moon, and became a pile of scrap metal.

In addition, due to cost and technology limitations, some ineffective space exploration facilities could not be recycled to the earth and had to be left in space. Some of them were left on the moon. thus became the back of the moon. iconic "landscape".

Such a discovery naturally disgusts some people, and some scientists accuse Hawking of warnings.

The great physicist Hawking has repeatedly warned mankind not to conduct space exploration prematurely, let alone send signals to the unknown universe easily.

In Hawking's view, it is obviously very unrealistic to say that there is only life on earth in the vast universe. However, humans have never discovered the existence of extraterrestrial life . This shows that the level of alien civilization has already Far beyond human civilization.

In order to compete for the limited resources of the universe, competition among civilizations is inevitable. If aliens are not so friendly, then they will "fight" humans for resources. There is no doubt that based on the current level of human civilization, this fight is obviously a unilateral crushing of alien civilization.

Therefore, judging from the current level of human civilization, Hawking does not agree with premature exploration of the universe and aliens for the sake of the safety of humans and the earth.

The discovery of Chang'e 4 further supports Hawking's point of view. The moon is the closest planet to the earth, but even so, it took humans many years to take into account the complete appearance of the moon, let alone understand the details in depth.

Later, in the lunar soil brought back to the earth by Chang'e 5 , scientists discovered some metal that had never been seen on the earth. It is still necessary to know how this material was formed and its specific uses. This will only be known through further exploration of the moon.

From this point of view, under the current technological conditions, humans cannot understand the moon clearly enough, and facing the vast universe will only become more blurry.

Therefore, some scientists represented by Hawking believe that when civilization is not yet developed, premature and excessive exploration of the universe will bring danger to mankind.

In the vast universe, the earth is so small and human beings are so immature. It has to be said that based on the current level of human science and technology and civilization, exploring space is still a long-term undertaking and will face unknown risks in the process.

So far, humans have not found traces of the existence of extraterrestrial civilizations. This may be frustrating, but in a sense it is also a good thing, because it also shows that humans are still safe and there will be no aliens. People are coming to invade the earth.

Therefore, we must seize the opportunity to develop ourselves and continue to develop human civilization. In this way, even if aliens are discovered in the future, humans will not be easily manipulated.
