"Professor Smith, I have a question for you."

"Oh? What's the problem? Liu?"

"You said that since there is a universe that is very similar to ours, then if there is China on the earth in this universe, and there is also a me who looks exactly like me and has the same ancestors, then which me is the real me? "

"Well... if this issue must be discussed, it probably involves the true self and the true self. Theoretically speaking, there is no concept of true self in the multiverse, only the true self, that is, you are You, because your experiences are all unique. , just like if you come to his universe and meet someone who is like you, it means that he will not go to your universe at the same time. This experience is unique to you."

"What if our experiences were exactly the same before we met? Then can I think that the me who experienced the adventure in the universe is the real me, and the me in this universe is just a fake? But this doesn't make sense. Huh? And if we extend it further, for example, I have an older brother and a younger brother, if I also have such a bunch of brothers in this universe, and their experiences before I arrived here are the same as my brothers on earth, even the DNA They are all the same, so are they also considered my biological brothers?"

"Um...Liu, why are you asking me these things? Maybe you can try asking Ning."

"But aren't you a philosopher? Professor Smith, I think these are questions that philosophers should think about, right? Academician Ning studies mathematics and physics, which seems not to be related to these?"

…

These days, Smith feels like he's falling apart. Ning Wei spends most of his time in the control room of the control tower studying the astrophysics of the universe. In his words, it must be compared with the starry sky coordinates of the Yuan Universe. Since I don’t know how long I can stay here, these are valuable information.

Well, Smith couldn't argue with that statement. He thought so too. The only regret was that he didn't do much research on cosmology.

So these days, he could only deal with Liu Wei's boring questions.

Fortunately, March is here, so there is no communication barrier between the two. But it was precisely because of March that Smith felt extremely headache. Because in his opinion, Liu Wei, who is like a curious baby, is obviously not a good candidate for studying philosophy, and this guy is more suitable for arguing.

But in your spare time, it feels good to make a cup of coffee and look at the scenery on the observation deck.

Even though the scenery outside is actually quite monotonous, this is the universe after all. As long as you look at some scenery with a different mindset, you won't get tired of it.

Occasionally, Liu Wei would come over with a cup of tea and quietly watch the scenery with him, but more often than not, the two of them would still get into arguments that seemed messy to Smith.

Fortunately, after living like this for two months, we finally saw the light of day.

…

"Look, that's the moon." Ning Wei walked out of the control tower, pointed to the planet in the distance and said something. Then he probably felt that he didn't make it clear, so he immediately added: "It should be said to be the moon of this world!"

"The moon?" Smith looked in the direction Ning Wei was pointing, and then realized that he couldn't see clearly, just a vague spherical body there.

"What about Earth?"

"At present, our route is that the moon is in a straight line with the earth. We can see the earth in two days." Ning Wei said excitedly: "But the main thing is not to let you see the moon. You see, this is the Kuafu spacecraft passing by in March. Photos restored by the telescope released."

As he spoke, Ning Wei casually called up the holographic image just sorted out in March's database, and the next moment rows of buildings on the moon appeared in front of them.

"Wait, this is the back side of the moon? Can it be photographed so clearly?" Smith asked subconsciously.

"The original photo is blurry. This is the photo after remodeling and supplementing in March." Ning Wei explained.

"Then what are these rows of buildings?" Smith asked in surprise.

"It looks like a mine." Liu Wei, who has more life experience, gave his opinion.

"Well, I have the same opinion as March. There is already a relatively mature mining system on the moon here. It should not only be a mine, but also a refining factory." Ning Wei nodded and said.

"Mining on the moon?" Smith exclaimed.

"Yes, according to our analysis of the lunar soil, the moon has more than a hundred mineral deposits. For example, iron, titanium, aluminum, silicon, etc., and most importantly, the moon has helium 3, which is a rare mineral deposit on the earth. But according to our estimates, there are at least 9 million tons on the moon, and if used to generate electricity, it can be used by the earth for tens of thousands of years." Ning Wei followed Smith's words and answered.

"Helium 3? Nuclear fusion? Are you saying that the earth's civilization here has mastered nuclear fusion technology?" Smith asked in surprise.

"Who knows? Even if we don't master nuclear fusion, it's okay to do the mining and purification work first. I changed the route a little, and I should be able to see the earth in another twelve to eighteen hours. I Go get some sleep first and you continue."

After saying that, Ning Wei turned around and walked towards the lounge, leaving the two of them looking at each other on the observation deck.

After a long time, Smith suddenly said to Liu Wei: "I have a feeling that your Academician Ning seems to know something, but he did not share it with us."

Liu Wei listened to the words translated in the simultaneous interpretation headphones, thought for a while, and gave a very pertinent opinion: "If you feel this way, I think you should start to review yourself. Professor Smith, after all, Academician Ning Wei has always been A scientist who loves to share with others.”

After saying that, Liu Wei also walked to the lounge.

You will soon be able to see the Earth in another universe, which is quite exciting to say the least.

…

When sailing in the universe, the most anti-human thing is probably that there is no distinction between day and night. In this case, the human biological clock can easily become disordered. In fact, March has been working very hard to find ways to maintain the biological clocks of the three people on the spaceship. For example, the lights on the ship will show different brightness at different times. But apparently controlled artificial light isn't as useful as natural light.

At least for three people.

But generally when Ningwei takes the initiative to remind everyone that they should take a rest, both Liu Wei and Smith are still very considerate.

After all, everyone wants to see what the Earth in another universe looks like for the first time.

Although it is impossible to see it so clearly with the naked eye, the telescope on Kuafu combined with the AI ​​automatic modeling function in March is still very interesting.

After the three of them slept like this, not long after, more holograms were displayed in front of the three of them.

But this time the hologram gave Smith and Liu Wei more doubts.

"This is……"

"It was speculated in March that this is a garbage dump around the earth. These are space junk. Damaged satellites, space telescopes, space stations, spacecraft wreckage and a space port built in synchronous orbit have all become space junk. In the future, It will probably be affected by the earth's gravity and fall to the surface of the planet every year. But there is a high probability that there is no way to control the landing place of this garbage." Ning Wei explained, pointing to the ring-shaped waste in the picture.

"Space port?" Smith felt that his brain was not enough.

In fact, Ning Wei also introduced the space port plan to him on his own earth, but that was a plan thirty years later, and the space port was planned to be built to the edge of the solar system, but the earth here actually put the space port Built on its own synchronized track.

"Yes, the preliminary judgment is that it is mainly used for space delivery. For example, the minerals on the moon should be unloaded at this large port, transferred from here, or sent directly to the earth, or to other places. Maybe they are already on Mars or Are cities built on other planets in the solar system?" Ning Wei explained in a speculative tone.

Regarding the construction of a space port in geosynchronous orbit, Ning Wei actually has his own speculations. Most likely, the speed of development is still different.

The technology here is developed step by step. There is a high probability that when the planetary exploration mode within the solar system is realized, anti-gravity materials have not yet been developed on a large scale. In this case, the huge space transport ship cannot land directly on the earth, so to use the resources of other planets, a space port is naturally needed.

But what makes Ning Wei particularly puzzled is that the civilization on this earth has developed to this extent, why can't it avoid war?

"No, I can understand what the space port is for. After all, there are man-made mining areas on the moon. But why are there only wreckage left?" Smith asked confused.

"What else could it be because of? Apart from war, I can't think of any other reason." Liu Wei replied calmly from the side.

"War? Are aliens attacking the earth, or are the people inside attacking themselves?" Smith said, shaking his head.

"If it was an alien attack, there is no reason that the moon's mineral base was just abandoned, with no traces of the war. So it should be an internal war." Liu Wei gave his answer.

Ning Wei looked at Liu Wei, then at Smith, shook his head, and sighed: "Look, Professor Smith, I have told you that it is good to continue studying mathematics, but you insist on studying philosophy. As a result, Now your logical analysis ability is not as good as our Brother Liu, you are... nothing."

"I..." Smith wanted to say something, but suddenly realized that this seemed to be the case, and there was no way to argue. In fact, he really wanted to explain that he was really frightened by these scenes, so he ignored many clues, but when he thought that Liu Wei was the same as him, and everyone received the same information at the same time, this explanation seemed pale, so he simply didn't do it. excuse.

It was just the embarrassment that made him want to say something: "Why is there a war? It has developed to this point, why not live well?"

Ning Wei smiled and said: "This can really be discussed philosophically. I think we can start with the dictatorship of the majority over the minority."

"Um?"

Ning Wei said casually: "For example, when the world economy enters a downturn, people in developed countries suddenly find that life is more difficult than before. Just like you, who originally had a family fortune of more than 30 million, if the world develops according to your expectations If it goes on, as long as you don't lose money, it will be enough for you to spend your whole life. But something unexpected happened, and your more than 30 million yuan was suddenly worth only 300,000 yuan or less, making it impossible for you to maintain your relatively comfortable life. What will you do? manage?"

Smith pondered for a moment. They are all smart people. He immediately understood what Ning Wei wanted to say.

"I probably understand what you mean. But what I want to tell you is that my personal wealth was actually about 50 million ten years ago. In the past ten years, it has shrunk by more than 20 million. And this is without counting the shrinkage of inflation. .”

"Haha, Smith, you are a rich man who does not have high requirements for life, so this shrinkage has no impact on your life at all. But think about it, if the original middle class millionaire shrunk to this extent It has seriously affected their lives, but many people have no way to solve it, but they still have no worries, what will happen?" Ning Wei said with a smile.

Smith was silent for a long time and said, "You are too arbitrary, Ning."

"It's not that I'm too arbitrary, but you should read more about history. Professor Smith." Ning Wei shook his head and said.

"Ahem, I say you two should stop talking about these disappointing topics. There are only three of us on this ship and it's pointless to argue about this. Maybe we should discuss when we can arrive? And should we talk to that person? The connection between intelligent life on this planet?" Liu Wei acted as a peacemaker.

Of course, it may be that after Liu Wei calmly thought about it, he decided that this was the most important issue to consider at the moment.

"It only takes about half a month to reach the Earth-Moon system. And now that we are here, how can we not contact you? My idea is that Kuafu will arrive in the lunar orbit first, and then we will take the Feilong and go to the lunar base to see if there is any There are no clues that can be connected to the intelligent life here. If we can't find any clues, we can take a spaceship and get closer to the earth to see the situation." Ning Wei said cautiously.

There is no way, you really need to be careful about this.

The information given in the biological computer is still too little. Ning Wei didn't know what the situation was like on the earth right now, so he had to be careful. The main reason is that there is too little information about various weapons on the planet in the system. Ning Wei does not know whether the weapon systems on the planet will pose a threat to the Kuafu.

After all, this is a planet that has even built a space port, and according to the analysis of space debris, it would take a global effort to build a successful space port on their earth. However, there are three of them in the synchronous orbit of this planet. There are so many, and through analysis of the location of the wreckage, they may belong to three different countries. One can imagine how far this civilization had developed before the war broke out.

So you can never be too careful.

"This is the only way. By the way, Professor Smith, have you received training in putting on and taking off a space suit and walking on the moon?" Liu Wei looked at Smith and asked.

"Um...Ning, have you ever trained?"

"Of course, before Kuafu launched into space, I made a year of preparations, which also included these." Ning Wei spread his hands.

"Okay, Professor Smith, don't worry. In the next few days, we will go to the lower level to let Yue Yue simulate the gravity environment of the moon. I will train you to walk on the moon, how about it?"

"Liu, I suddenly realized that you are a gentleman."
