"One of my favorite aphorisms of Kant was said by my father when I was very young," Zhou Hui said.

"I still remember the look on his face when he taught me the constellations in the night sky and said those words to me, so reverent, so unquestionable."

"There are only two things in this world that can deeply shock our hearts, one is the brilliant starry sky above our heads, and the other is the lofty moral law in our hearts," Wang Yinan said.

"Except for this sentence, there is nothing more suitable for this starry sky."

Zhou Hui didn't have any surprised expression when Wang Yinan could guess this maxim, "Forget about the moral law, after returning to China, I will see too many people's faces, in this era, no one will talk to you about morality, it can only be a shackle that binds you." And you see, this starry sky for years, decades, or even hundreds of thousands of years, looks at us like this, silently, indifferently, and people can't help but be in awe."

"In fact, the starry sky now is completely different from hundreds of thousands of years ago", this is how the science and engineering man likes the scenery.

Zhou Hui glanced at Wang Yinan, in the cold moonlight in winter, this glance seemed to have a thousand styles, Wang Yinan suddenly felt that his mouth was dry, and he tried hard to change the topic,

"By the way, is your father an astronomer," Wang Yinan asked curiously.

"Not really", Zhou Hui's eyes showed a look of nostalgia, "He used to work at NASA (National Aeronautics and Space Agency) and had the opportunity to learn about some of the data obtained by the Apollo moon landing program."

"In this way, I remember that Apollo 8 has already achieved a manned flight around the moon, not to mention that Apollo 11 has achieved a human landing on the moon, and of course, the most famous Apollo 13, I can't understand why they didn't skip the damn 13."

"To be precise, my father is a seismologist, and his field of research is very unpopular, which is the earthquake of extraterrestrial planets, that is to say, earthquakes on Mars, the moon and other stars are his research objects."

"That must be interesting," Mr. Wang said.

"The technology of the sixties was actually relatively backward, and only the special factor of the Cold War catalyzed the implementation of the moon landing program, and if normal science and technology were developed, mankind would not necessarily be able to land on the moon in another fifty years."

"So in the flight of the Apollo series of spacecraft around the moon, the resolution of the camera is very limited, and the capacity of the storage device is not enough, in fact, NASA did not obtain very high-resolution images of the moon, let alone images of the far side of the moon, so the image data is actually not the biggest gain of the Apollo program."

"What the outside world doesn't know is that during the Apollo moon landing, there were many seismic detection instruments," Zhou said.

"Ah, I don't think there's been a report on this."

"Yes, this is some special-purpose instrument, there are no public reports, and the Apollo spacecraft has conducted several explosion tests on the moon."

This time, Wang Yinan was completely shocked, "Ah, actually Mi Guo has done this kind of thing, and it is too exaggerated to put a bomb on the moon."

"Well, in order to study the geological structure of the moon, several explosive devices were actually buried and a lot of data on seismic waves was collected when the TV footage was not broadcasting."

"My father had the opportunity to come into contact with these seismic wave data later, and using new computer technology later, from Apollo 11 to finally 15, he found some very interesting things from the collected seismic wave data," Zhou Hui said.

"What is it?" Wang Yinan asked,

"The propagation of seismic waves suggests that there is a high probability that on the far side of the Moon, there are certain artificial structures",

"No", Wang Yinan was really dizzy, "Isn't it a remnant of a certain moon landing",

"Definitely not, humans have never landed on the far side of the moon",

"Damn, does the mysterious Area 51 really exist, but what about later?" , Wang Yinan asked,

"Then the author became a eunuch... , Zhou Hui, of course he didn't say that, "Later, Mao Xiong gave up the competition with the United States, and the Apollo program had no competitors, and Congress refused to allocate funds",

"In addition, there was a major accident in Apollo 13, and the three astronauts almost did not come back, so after arriving at Apollo 15, all subsequent plans were canceled."

"My father didn't have more detailed data to analyze, and then he retired and returned to China, and until his death, he still remembered those seismic wave data." Zhou Hui said,

"I still remember that when he was dying, he was still holding my hand, and kept saying, I really want to go and see what the far side of the moon is", as he spoke, Zhou Hui's tears fell again.

Wang Yinan looked up at the bright moon in front of him, in the cold winter night, it seemed that the whole world was shrouded in silver light, could it be that there was really a Chang'e running to the moon on the moon? And Wu Gang and Jade Rabbit who cut wood? What kind of secrets are hidden on the other side of the moon, which has not been seen by people for thousands of years?

"I went back to find someone from the Science and Technology Commission, it seems that the Chang'e project is in charge of them, and the latest lunar vehicle of the entire Blue Star is theirs, and they should have high-definition photos of the far side of the moon, maybe they can find something," Wang Yinan said.

"But it stands to reason that you should be engaged in a science and engineering-related career, how did you enter the showbiz all of a sudden, this span is a bit big", Wang Yinan asked.

"My mother was the earliest film actress in China, and then for some reason she went to the United States and met my father."

"I should have inherited my mother's genes, and I like to perform or something", Zhou Hui seems to be reluctant to mention her mother.

"Later, when my father returned to China, I went to the Imperial Capital Film Academy, and I slowly became like this."

"Whenever things don't go my way, I always like to look at the starry sky above my head, and in front of a masterpiece like the Creator, it seems that all the grievances and unsatisfactory things don't matter."

Unsatisfactory, Wang Yinan sensitively captured the word in Zhou Hui's words, "What's wrong, today's premiere should be a very happy thing."

"Hehe, are you optimistic about our movie", Zhou Hui asked,

"Truth or falsehood",

"Nonsense, falsehoods, compliments, I still need you to say."

"Okay, this film is just a piece of X, no story, no special effects, you say remake, and there is no faithfulness to the original work, you say innovation, and you don't know what to do at all, no thoughts", Wang Yinan said unceremoniously.

"Yes, I also know that in recent years, I have made this kind of film, which is meaningless", Zhou Hui said,

"But how can we have any autonomy as an actor, there are only a few good films every year, and the director has his own familiar actors, Director Lou is a director who has a good relationship with me, you have also seen it, now he has been completely captured by capital, and the bosses who contribute to the capital are all according to their own preferences, and there is a haunt and a haunt. The screenwriter has no soul of his own, and what he finally shoots is such a shitty hodgepodge."

Zhou Hui turned around, leaned in front of the eyepiece of the Schmidt telescope, and carefully looked at the moon in the lens.

Wang Yinan thought to himself, well, it seems that space exploration is going to be added to Gödel's development plan. But this thing is super money-burning, I think back then, the huge hairy bear was dragged down by the United States. Of course, that's because space technology surpasses the scientific and technological base of the sixties too much, so it costs too much, and now it seems that Musk's SpaceX has created a new low-cost space path, and it will be necessary to study it well in retrospect.

Space engine is the foundation of space exploration, the current mainstream is liquid hydrogen liquid oxygen engine, as well as liquid oxygen kerosene engine, Maozi's RD80 is currently the best performance and reliability of the liquid oxygen kerosene engine, Musk's initiative is to make the rocket engine can be soft landing recovery, thereby greatly reducing the cost, but liquid oxygen is not necessary in the atmosphere, Wang Yinan secretly wondered, can you make some fuss in this regard.

"Let's go", and finally looked at the moon in the lens, Zhou Hui said, "It's almost time."

Wang Yinan turned off the equatorial mount, loaded the binoculars, carried the big bag, and returned to the parking lot with Zhou Hui. "The telescope was given to you", sitting in the car, Wang Yinan said,

Zhou Hui thought for a while, "It's too troublesome, you have to use it with your mobile phone, install an App or something, and if something goes wrong, you have to debug it",

"When I want to see the stars in the future, I'll just look for you."

Wang Yinan almost didn't smack his mouth, why am I so stupid, if Zhou Hui really accepts the binoculars, what reason will she find to ask herself to look at the stars in the future, it is really stupider than a pig.

Today is the weekend, even if it is late at night, there are still so many cars in the imperial capital, hurry up and hurry, and the two finally came to Dongda Hutong at eleven o'clock.

Although it is a premiere of a movie destined to hit the street, the fate of our book is the same, the difference is that there are many big and small stars in the movie, and there are still many fans, and the publisher has also prepared a red carpet ceremony.

It stands to reason that Zhou Hui should be called the actor who has no sense of existence, yes, Li Yi walked the red carpet together, but obviously she had other plans, Wang Yinan drove to the front of the red carpet and knew that it was going to be bad, Zhou Hui didn't tell him that there was this link before.

The off-road vehicle stopped, and the staff on the side of the red carpet pulled the car door, but Zhou Hui didn't come out for a long time, Wang Yinan finally understood that Zhou Hui naturally sat in the co-pilot's seat before going to see the stars.

No way, sister's set, you have to jump with tears in your eyes, Wang Yinan got out of the car and threw the key to the staff, fortunately, this guy has also seen it in Prague, but he doesn't have to worry about not finding the car. Walking to the door of the rear car, Wang Yinan bent down and stretched out his arm, and saw Zhou Hui leaning out, holding Wang Yinan's arm, and jumping out of the car.

The two walked along the red carpet towards the cinema together, and the brainless fans shouted "Zhou Hui, Zhou Hui", "Zhou Hui, I love you" on the side, of course, more fans are wondering, who is this buddy next to Zhou Hui, why haven't you seen it, it doesn't seem to be that Li Yi or something.

Feeling the puzzled eyes of the fans, and a few cannibalistic glances from the crew, Wang Yinan asked in a low voice, "On purpose,

"Well, I should pay you to watch the stars, I should always pay something",

"Is it okay for me to accompany you to see the stars",

'People are girls, my dad said that men should let girls' go",

"Then you also want me to die to understand, who has the most powerful firepower in those murderous eyes, and I will walk around him when I turn around",

"Li Yi, you know it, you definitely don't have to be afraid of that cream boy", "The one on the side who looks black and thin is the son of an investor, you'd better hide",

"Damn, you hurt me, it is said that this film was filmed by investors to please you, isn't that the reason for this kid",

"So it's the happiest to talk to smart people", Zhou Hui hugged Wang Yinan's arm tightly and walked towards those murderous glances,

Wang Yinan's heart has 10,000 divine beasts rushing by...

Just look at the stars, not really.
