Technology's opening live broadcast to build rockets

"There is nothing here. The detector shows that there should be just ordinary rocks inside the high platform." Su Peng searched carefully several times, but still found nothing.

"Did someone take it away?" a team member asked doubtfully.

"It's possible, after all, it's an alien civilization." Yao Feng touched his chin and thought.

"The high-dimensional information is here." The technology simulator said to Du Xingyu, "I am also a high-dimensional creation of human civilization in parallel time and space. I have a certain ability to perceive information from high dimensions."

"So, it's not that it's missing, but that as three-dimensional creatures, we can't see it at all?" Du Xingyu's heart moved.

The universe is multi-dimensional. To put it simply, zero latitude can be imagined as a point with no length, width and height.

One dimension is a line without height or width.

Two dimensions are planes with no height.

Three dimensions are spaces with length, width, and height. The fourth dimension is a world with an additional "time axis" on the three dimensions... and there are five dimensions, six dimensions, etc. above.

Human beings are only three-dimensional creatures. Without a high-dimensional perspective, they naturally cannot see high-dimensional information and creation.

For example, there is a two-dimensional creature, which is a paper man living in a comic. There are only line segments in his perspective and he cannot see "us" in the three-dimensional world.

In the same way, human beings, as three-dimensional creatures, cannot see high-dimensional creations that are clearly placed on high platforms. Because although it is placed there, it is in the high-dimensional space of that coordinate, not the three-dimensional space that humans see.

"That's more or less what it means." The technology simulator said.

"Do you have any idea?" Du Xingyu had no idea about this. A high-dimensional creation is placed there, but as three-dimensional creatures, they cannot see or touch it.

"No." The technology simulator was very straightforward.

"The bottles in the mural look like Klein bottles." At this time, Xu Lianqiu was still studying the mural.

The Klein bottle is a geometric object proposed by the mathematician Klein.

That is, there is a hole in the bottom of a bottle, the neck of the bottle is extended, and twisted into the inside of the bottle, and then connected to the hole at the bottom. There is no distinction between the inside and the outside of such a bottle. It is not a sphere, but a point traveling along its surface in any direction will not encounter an end point.

The neck and body curves of the Klein bottle appear to intersect, and appear to be broken in some places, but they do not intersect with themselves - in short, they only appear in a three-dimensional perspective. This is a contradictory feeling, but if you look at it from a four-dimensional perspective, the image of the Klein bottle is actually a continuous curve.

"Oh, it's true!" Others also discovered this.

Xu Lianqiu followed the location on the mural and came to a certain place on the high platform. She stretched out one hand and said: "The meaning of the mural may be that at this location, the owner of the spaceship placed all its things in a certain space. Within. We just couldn’t find the space.”

Everyone is thinking about the team members who are qualified to come to Mars for scientific research. Each one of them is a leader on earth. They have active minds and can think of many possibilities with a little bit of information.

The scene fell into a brief silence, until Xu Lianqiu's exclamation woke everyone up.

"My hand is missing?" Her jade-like palm disappeared out of thin air!

"What's going on?" Everyone was stunned. How could a person's palm disappear out of thin air? And from their perspective, Xu Lianqiu's hand seemed to be suddenly invisible, and the light no longer refracted back to people. of retina.

"I can feel my palm!" Xu Lianqiu remained motionless, her expression very strange: "I feel it's still there, but I can't see it."

Du Xingyu said quickly: "Maybe your palm has entered a certain space, take it back and try!"

Everyone has questions in their head about the unknown.

"Oh my god, my world view has been completely overturned today!" Su Peng said with emotion.

"I'll try!" Xu Lianqiu tried to retract her palm, and everyone saw that her palm reappeared.

"Do you feel anything?" Du Xingyu asked.

Xu Lianqiu moved her palms and said, "Nothing unusual."

"No, there is an extra pattern on the palm of my hand?" Her almond-shaped eyes widened, and she looked at her palm in surprise. There was a pattern of a "Klein bottle" on it, which was the bottle in the mural.

"What the hell is going on? My brain is not enough!" Jiao Mengyun grabbed his hair.

Not to mention her, Du Xingyu was also confused at this time. He knows nothing about the methods of high-dimensional civilization.

Xu Lianqiu rubbed it carefully, but the pattern was not ink and could not be rubbed off at all. Looking carefully, it was not something similar to a tattoo or a tattoo, because it was evenly distributed on Xu Lianqiu's palm and would not be stretched by the skin. Change by stretching or locking. In other words, the pattern exists in a two-dimensional plane in her palm!

"I can detect that the information of high-latitude civilization is left in the palm of her hand. It seems that in that space, this creation has changed its form and become two-dimensional. It is very strange." The technology simulator explained to Du Xingyu, "I I don’t know what it is.”

"It seems that before I come into contact with Latitude Technology, I'm afraid I won't be able to understand this thing." Du Xingyu sighed helplessly.

"What is this?" Everyone was still studying the thing in Xu Lianqiu's hand.

Others continued to explore the place where Xu Lianqiu's hand disappeared, but this time no strange phenomena appeared.

Du Xingyu became serious and said: "There is no doubt that this is caused by some kind of technology that we cannot understand. It may be information left by advanced civilization. No one is allowed to leak anything that happened here today!"

"This is a ban issued by me as the supreme commander of the alliance. Do you understand?"

Seeing how cautious he was, everyone immediately said seriously: "Understood!"

This ruins has been sealed off, and some people will continue to explore it, but the most important information has been taken away by Xu Lianqiu.

Back at the Mars base, Du Xingyu had her tested in all aspects, but almost nothing was detected.

There was only one strange thing. The cell test results showed that Xu Lianqiu's cell activity had increased. In other words, her life status had become very active, and some of the hidden diseases in her body had disappeared.

This state also amazed medical experts and left them puzzled.

But Du Xingyu was not too surprised by this. Because Xu Lianqiu's current physical condition is very similar to his.

After he obtained the technology simulator, his body also unknowingly underwent some kind of change, so his thinking speed, ability, and health were much better than ordinary people.

If this continues, he can easily live to be over a hundred years old, but currently he cannot break the limit of human lifespan.

"Her state is different from yours." The technological simulator said, "Maybe she can break through the limit of human lifespan."

"I'm getting more and more confused. What is the information of that high-dimensional civilization?" Du Xingyu couldn't find the answer. So far, the pattern has not had any impact on Xu Lianqiu in other aspects.

"These problems are not something you can understand now." said the technology simulator. "Maybe you should worry more about yourself. There are still many things you have to do."

"Yes." Du Xingyu brought his thoughts back. The Death Star was still flying towards the earth. He didn't have much time to find the answer, so he could only put the matter aside for the time being.

Before leaving, in the cafe of the Mars base.

A man and a woman are sitting opposite each other, and the man is reading "palm reading" to the woman.

Du Xingyu held Xu Lianqiu's green fingers and stared intently at the Klein bottle pattern in her palm.

"Congratulations, you will become the new top ten unsolved mysteries of the world!" Du Xingyu joked.

"Then I'd rather not do it, I still have to be studied every day." Xu Lianqiu complained, "Now I'm almost a national treasure in the base, and people ask about my sleep, diet, and even my dreams every day."

"Isn't this a good thing? Everyone cares about you." Du Xingyu smiled.

"It's a pity that someone is missing." Xu Lianqiu held her chin and looked at him quietly.

"The situation is compelling!" Du Xingyu smiled bitterly.

"Do you still remember the scene when we first came to Mars? We encountered a sudden dust storm when we first arrived. It has been almost ten years." Xu Lianqiu said with emotion, "How many decades can life last?"

Du Xingyu also felt a little surprised. It turned out that almost ten years had passed since the two of them hugged each other to escape the dust storm!

His friends had already gotten married and had children, but he had always ignored time. There are not many friends left who can still be with each other.

When he looked at Xu Lianqiu again, Du Xingyu suddenly felt filled with emotion. They had been working non-stop for ten years, but even if they hadn't seen each other for a long time, they would still feel familiar and friendly when they met.

There may not be the twists and turns of a love story in a drama, but the feeling of being connected is more important than anything else.

He stood up and said to Xu Lianqiu: "Three years, if human beings can cope with the crisis in three years, we will be together."

"Ah?" Xu Lianqiu didn't expect that he would suddenly say these words, and was stunned for a moment. Then an unconcealable joy surged from the bottom of her heart, and even her neck and ears were dyed a little crimson.

"Yeah!" She waited for this sentence for so long that she didn't feel pretentious at all, so she quickly agreed to avoid Du Xingyu regretting it.

"Commander Du, the Silver Wing is arriving soon!" Someone interrupted their rare intimate moment.

"Okay, I'll be right away." Du Xingyu turned to look at Xu Lianqiu and said, "If you have any news, tell me as soon as possible."

"I gotta go!"

"I'll wait for you." Xu Lianqiu bit her teeth and stared blankly at his leaving figure.

…

The love between children is definitely not Du Xingyu's expertise. Soon, he returned to Earth and threw himself into work again.

In the military factory on the moon, construction of the "space meteor hammer" has begun.

Physics experts, materials experts and military weapons experts from all over the world are making suggestions for asteroid impactors.

The moon's gravity is relatively small, and the asteroid impactor that is successfully built will be easier to enter and use in space.

From the ground, a large amount of metal is transported into space every day through the ladder to serve as the head of the meteor hammer.

One year later, the first asteroid impactor, Space Meteor 1, was manufactured at the lunar military factory.

Its maximum cross-sectional diameter is one hundred meters long, and its mass is one million tons!

If this kind of mass were on the earth, it would be really difficult to send it into space using thrusters.

But the moon's gravity is smaller and there's no air resistance, so pushing is much easier.
