After finishing the process of allowing the Kuipers to resurrect the deceased using the tissue specimens they brought, Qiu Siyuan discussed the next itinerary with everyone.

"I want to go sightseeing in the Oort Cloud." Lu Tong first expressed his wish. Because like the Kuiper Belt, it is an annular belt surrounding the sun. However, compared to the Kuiper Belt, the Oort Cloud is very far away.

You must understand that the distance of the Kuiper Belt from the sun is about 30-50 astronomical units, which is equivalent to more than seven billion kilometers.

The Oort cloud is about 50,000-150,000 astronomical units from the sun. It is equivalent to 9.46 trillion kilometers (nearly 1 light-year). Therefore, the natural environment there is worse than the Kuiper Belt. It is an extremely cold and dark place.

In the heavens, the gravitational pull of the sun is also very weak.

However, the Oort cloud may not be the boundary of the sun. Because the boundary of the sun is the contraction point of the junction of two different celestial bodies, it cannot be as fluffy as a nebula. The Oort cloud is thicker and should be

A layer of space that is not very dense and is made of materials such as ice cubes and snow masses.

In nature, many celestial bodies and living things have hard shells. Although some do not have hard shells, they still have certain boundaries. For example, the inside of the earth and the inside of eggshells have similar structures. This should be a natural hint.

"Let's go sightseeing in the outer shell of the solar system." Cui Jianfeng said: "I heard Sun Xiaogang say that there are a large number of Kuiper Space Exploration Bureau personnel doing construction in that area?"

"What kind of place is there? What kind of projects are the Kuipers doing there?" Chen Yuntian asked curiously. Because he and Sun Xiaogang often quarreled, they learned a lot about nature.

"They are carrying out the operation of penetrating the solar system's crust between the layers of the solar system's crust," Sun Xiaogang said.

"Why should we go there for sightseeing?" Lu Tong asked curiously.

"They used to use flying balls to go there. Due to the high density of floating stars in that area, it is generally not suitable to use flying saucers like interstellar navigation. Now they use the tachyon transmission system."

"Flying ball?" Chen Yuntian looked at Sun Xiaogang in confusion: "Isn't the flying ball the same saucer-shaped house we sat in when we went to the moon?"

"According to your Tang Dynasty understanding, a flying ball is a round house like a watermelon." Sun Xiaogang gestured with his hands.

"Then why don't they use butterfly houses?"

"The main reason is that the distance between floating stars in that area is not very large, so it is not suitable for high-speed spacecraft navigation in a wide space like inner space." Sun Xiaogang said.

"Now that we have switched to the tachyon transmission system, do we still need to use flying balls?"

"This kind of project is inseparable from flying balls, because the tachyon transmission system is first installed with flying balls, and then people can be sent to the tachyon transmission box there."

"Oh." Chen Yuntian smiled: "Then we will transfer from the tachyon transmission box here to the tachyon transmission box there, and then go to see their construction site. Right?"

"We can only go sightseeing in the flying ball equipped with the tachyon transmission system specially prepared for us. It is impossible to have face-to-face contact with them." Sun Xiaogang explained.

"why?"

"The main reason is that the Kuipers are different from us. They are people who live in an environment of weightlessness and biological diversity. They cannot come into contact with us who live in a gravity field and biologically diverse environment, otherwise they may be infected by us.

The microorganisms in them are infected and die. They are also different from the flying balls we use. Their flying balls do not have artificial gravity fields, but our spaceships are equipped with artificial gravity fields. In this way, as soon as they enter our flying balls

Once inside, their body tissues will be damaged and they will feel uncomfortable or even die. Similarly, if we enter their flying ball, it will be just like if we enter space without protection, we will die quickly.

"

"But the short gray-brown man who copied me that day, wasn't he a Kuiper? Then he and I stayed in the same house, why was he okay?" Han Fengying thought of the hateful-looking man she saw that day, and she must have thought about it.

They were the Kuipers that Sun Xiaogang mentioned just now, so he asked in confusion.

"Those are the people sent by the Kuipers specifically to serve us. Their tissues and organs are the same as ours, and they are only suitable for living in a biologically diverse and gravity environment."

"So that's it." Cui Jianfeng suddenly realized and said with some disappointment: "So, we can't go to too many places, we can only go to a few flying balls in the solar system shell layer that they specially prepared for us. This way

It’s also called sightseeing.”

"Actually, even if we don't go anywhere, we can watch videos there from here. However, it's better to visit there." Sun Xiaogang said.

"Why?" Lu Tong asked.

"Because, when we go there, we can roam in the solar system's shell under the guidance of a tour guide, and see a large number of floating stars in the solar system's shell from the monitor through the sky eye outside the flying ball. We can also go to the construction site,

Watch the Kuipers 'drill' into the solar system's crust."

"Why do they want to 'drill' the 'shell membrane' of the solar system?" Zhu Guangcai asked.

"I want to pass through the shell of the solar system and the shell of the outer galaxy, and enter the inner space of the outer galaxy." Sun Xiaogang said.

"Is it really so difficult to leave the solar system?" Zhu Guangcai asked curiously.

"Yes." Sun Xiaogang seemed to think of the last round of Earth's prehistoric civilization 700 million years ago, and said with infinite emotion: "Back then, space scholars from our Asian tribes often launched deep space probes, and they all thought that their deep space probes were

Once the space probe passes through the Kuiper Belt, will it leave the solar system and enter an outer galaxy?"

"Deep space probe?" Zhu Guangcai asked, "What is it?"

"It is launched by a rocket and has a small detector on its head. It is a signal conversion probe that takes pictures of the scenery in deep space and sends it back to the monitor of our last round of Earth space scientists."

"What happened after the launch? Did it fly out of the solar system?" Lu Tong asked.

"Didn't you see that the Kuipers still haven't rushed out after 600 million years?" Sun Xiaogang laughed: "Human beings from the last round of earth civilization (prehistoric civilization) failed to successfully break out of the solar system until the end of humankind in prehistoric civilization.

"

"Then why did the Kuipers spend 600 million years and still not break out of the solar system?" Zhu Guangcai asked puzzledly: "With such a high level of technology, can't they even escape from the solar system?"

"This is mainly because they used mechanical and optoelectronic equipment to use flying balls to penetrate the solar system's shell and enter the inner space of the outer galaxy. They have been working hard for many years, but they still failed to achieve their goal, just because they stayed in the optoelectronic information field.

In the era, space travel across the solar system was not practical because the contact point between the shells of the two galaxies was not fixed but moved relative to each other. In this way, once the flying ball entered the shell of the outer galaxy, it would be swept away by the shell of the outer galaxy and lose contact.

Therefore, mechanical and optoelectronic equipment cannot achieve the goal of flying out of the solar system. It is completely unrealistic for humans based on photoelectric information to want to leave the solar system."

"So what's going on now?"

"I heard from the Kuipers that since the discovery and application of tachyon teleportation technology, they have successfully used the tachyon teleportation system to penetrate deep into the solar system's shell, and now they see hope of success."

"Then they haven't broken out of the solar system's shell yet?"

"Yes."

"Then where did the deep space probes you launched 700 million years ago fly to?" Zhu Guangcai seemed to be very concerned about the fate of the deep space probes launched by humans in the last round of earth civilization.

"Who knows? Anyway, after they were launched, they talked a lot about the detectors that had flown away from the sun and flown very far away, and were discovered and taken back for study by humans from extraterrestrial civilizations."

"The results of it?"

“After the Kuipers awakened us humans from the last round of earth civilization 700 million years ago, I also heard some Kuipers who have been engaged in exploration work in outer space for a long time say that they often picked up objects dropped from certain floating stars during construction.

They often pick up these things and bring them back to Kuiper Space City for their children to play with as toys?” (Haven’t the Kuipers entered the era of asexual reproduction and directly cloned people? Remember,

The time when the Kuipers began to come into contact with the outer shell of the solar system was 700 million years ago. At that time, they did not directly replicate humans, but used cloning and other technologies to reproduce themselves from small to large!)

"You seem to have said just now that you are the last round of earth civilization in an environment of gravity and biological diversity. The Kuipers cannot meet you directly. As for the deep space probe they launched, they picked it up and made it available to their own family.

Children play with them as toys. Aren’t they afraid of being infected by the diverse organisms on the detector?”

"I don't know about this. However, I think that these deep space probes flew through the large-scale universe of more than ten trillion kilometers (nearly one light-year), and then fell into the extremely cold floating stars in the solar system's shell.

On top of it, the various microorganisms on it may have disappeared long ago and no longer pose any threat to them."

"What you said makes sense, and it makes me want to go sightseeing in the solar system shell layer even more." Chen Yuntian smiled, so innocently and brightly that he looked very much like the official uniform of a fourth-grade official in the Tang Dynasty.

It was disproportionate, which also made Sun Xiaogang feel funny.

"I have contacted the Kuiper Space Exploration Agency." At this moment, Qiu Siyuan walked in quickly and said happily: "They have agreed to let us go to the solar system shell layer to visit the ongoing intersystem contact crossing.

experiment."

"What?" This time it was Sun Xiaogang's turn to ask Qiu Siyuan in confusion: "What is the inter-system contact point crossing experiment?"

"That is, the contact point between the shell of the solar system and the shell of Proxima Centauri (system) goes from the space in the solar system to the space in Proxima Centauri (system). It is referred to as the sun-contact point."

"I'm a little confused." Sun Xiaogang looked at Qiu Siyuan in confusion: "According to the Kuipers, the solar system's shell is composed of a dense layer of floating stars tens of thousands of kilometers thick. But when we look at it from the earth, we can see

The starlight outside the solar system, wouldn’t such dense floating stars block the starlight outside the solar system?”

"That's it." Qiu Siyuan smiled: "I also curiously asked Kuiper space scientists similar questions. They said that this may be a question that you people on earth will not be able to figure out until the end of the world."

"what do you mean?"
