At nine o'clock in the evening, Zhang Zhi looked out the window, and he and Qu Xiaoyan debated during the day. It was still affecting his thoughts.

Zhang Zhi looked at the bright moon in the sky. The moon, it's so special.

We know that Earth is unique in the known universe. But few people care that it has a satellite that is also unique in the universe.

Zhang Zhi looked at the moon in the sky, and against the backdrop of many stars, it looked so different. Thanks to the elimination of haze, the moon can be clearly seen at night in Yanjing.

Every time Zhang Zhi sees the moon, he has a chilling feeling, which is the unknown and magical thing that human beings have. An instinctive reaction.

This feeling comes from seeing the size of the moon. It is almost the same size as we see the Sun from the Earth.

People have been accustomed to this phenomenon for thousands of years. Ask a few more times why? It will give results that are different from common sense.

Modern measurements show that the diameter of the Earth is 12,756 kilometers, and the diameter of the Moon is 3,476 kilometers, which is 27% of the diameter of the Earth.

The diameter of the Moon is 1/395 of the diameter of the Sun, and the ratio of the distance between the Moon and the Earth to the Sun is also 1/395, that is, the two ratios are the same.

So, the size of the Moon and the Sun that we see on Earth is the same.

Speaking of solar and lunar eclipses, the Moon can completely block the Sun at certain times.

At present, there are no coincidental distances in galaxies that can be explored by humans, and there is no phenomenon similar to solar and lunar eclipses.

One rotation of the Moon is exactly the same as the time of one revolution, so we can only see one side of the Moon on Earth forever, but not the other side of the Moon.

The Moon has no magnetic field, it lacks iron on it, and it has no atmosphere. It would have no means to resist the solar wind, and there would certainly be no life on the moon.

The elemental composition of the Moon is different from that of the stars of the solar system. It is certain that the Moon came from the distant universe in the solar system.

According to the gravitational explanation, if the Moon wanders from the universe to the solar system. As soon as it enters the solar system, it is first attracted by the gravitational pull of Jupiter, which is huge.

It will never run to the edge of the earth. For the Moon to be close to the Earth without colliding head-on with the Earth, and to orbit the Earth, according to the current scientific theory, it is an impossible event to happen.

But in reality, the moon is in orbit on the earth, which is an incredible thing.

We think that coincidences are everywhere in the universe, and that the Moon is captured by the Earth's gravity at the right time and at the right angle.

In this way, the Moon, like other moons, should have an elliptical orbit. But the orbit of the Moon is also very strange, it is different from other celestial bodies.

The orbit of the Moon turned out to be round, and it was close to a perfect circle. Strictly speaking, the orbit of the Moon is also elliptical, but on the scale of the universe, this slight difference can be considered to be perfectly circular.

In the known universe, the moons of all planets, its orbit is elliptical. With the exception of the Moon, the Earth's satellite.

Zhang Zhi thought that there was another kind of satellite whose orbit was also perfectly round. That's Sputnik. Thinking of this, he only felt a feeling of cold wind blowing on his face, and his whole body was excited.

Now only one country declares itself to go to the moon. That's the United States and its Apollo program.

Zhang Zhi used to collect every report on the Apollo program released by the United States out of curiosity.

Zhang Zhi still remembers an experiment that he remembers.

At 4:15 a.m. Central Standard Time on November 20, 1969, Apollo 12 conducted an impact experiment on the surface of the moon and caused a moonquake.

The moonquake lasted more than 55 minutes, and the shaking gradually increased from small to large, and then gradually weakened in amplitude.

The tremors were described by the scientists who studied it as that, like ringing a church bell, the shock wave only traveled from the epicenter to the periphery of the moon's surface, but not to the interior of the moon, as if it were a tremor on a completely hollow metal sphere.

This experiment contributes to the fact that the Moon is much less dense than planets of the same size.

NASA said in the report "Apollo 16 and the Lunar Surface" that a study of the moonquake caused by Apollo 12 found that there is a hard layer about 64 kilometers thick inside the lunar crust.

The only explanation is that down from the surface of the moon, there is a very hard layer of material. And this hard material structure should be a shell made of special metal.

Zhang Zhi understands that this is the statement of the United States, and all the evidence is disclosed by the US government agencies. At that time, it was still a time when the United States and the Soviet Union were competing for hegemony.

This cannot be ruled out as part of the Star Wars program used by the United States to lure the Soviet Union into being fooled.

The United States has a criminal record, and if it cannot prove it on its own, it must remain skeptical of the United States' claims.

Zhang Zhi also knew that there were too many strange places on the moon. All kinds of peculiar performances make people wonder whether it is a product of science and technology.

It is a pity that there is no information on the moon in the science and technology library. They're in the history library.

The secrets of the moon are still to be explored by their generation.

No matter how much the United States says, it will not tell all its secrets, and it will certainly engage in true and false information to confuse others.

Xingyu Technology now also has some capital, especially the successful development of intelligent life.

With Star Blue's central command, she can let robots take the place of humans and explore the moon.

Without a human life-sustaining protection system, the difficulty of landing on the moon has dropped exponentially.

It's time for Xingyu Technology to gather scientific research talents and research the technology to explore the starry sky.

Zhang Zhi predicts that in the coming decades, in the fierce competition environment of the earth, the world's major powers will have nuclear weapons to maintain the strategic balance.

This is an era of space exploration, and whether or not it can be developed in space in the future is the best way to judge a country's heritage.

In particular, the battle for the strategic point of the moon. If directed energy weapons such as laser weapons and particle weapons are deployed on the moon, it will hit the earth in a very short time. Or a 24-hour global strike.

Any country will compete for this opportunity, and this is the age of the stars and the sea, which is even more magnificent than the Age of Discovery.

Zhang Zhi was born in this era, and this is his unshirkable responsibility. Of course, you have to do it.

Zhang Zhi heard the sound of the door opening, he turned around and saw that it was Li Lingqiu coming back.

Li Lingqiu saw Zhang Zhi standing by the window, and she asked with concern, "Have you eaten?" ”

Zhang Zhi said with a smile: "I know you haven't eaten, I'll cook a meal for you." Wait for you to come back and eat together. ”

Li Lingqiu said in surprise: "You can cook, whether it is braised pork rib noodles or Laotan sauerkraut noodles." ”

Zhang Zhi asked the robot to serve the meal, and he said happily: "This is my newly learned egg custard." ”

Li Lingqiu sat down and tasted it, and said with satisfaction: "If boiled eggs are counted as one dish, you have mastered two dishes now." ”

Zhang Zhi asked Li Lingqiu: "Lingqiu, you have made significant progress by coming back so late. ”

Li Lingqiu said happily: "All the problems have been solved, and the rest is to optimize slowly." ”

After Zhang Zhi and Li Lingqiu finished washing, they went to rest.
