The intersystem travel experiment was about to begin. The specially invited leading figures from Kuiper's space cities who gathered in the spherical hall of the observatory could not conceal their inner excitement. They floated on a small spherical shelf in the center of the hall, watching the circle with their eyes open.

The ding shows a violently rotating two-system shell contact vortex and more than a dozen unmanned flying balls (actually not a dozen) floating among floating stars not far to the south of the vortex.

Most of them float among the floating stars, so they cannot be seen).

These unmanned flying balls are equipped with tachyon transmission systems. In this way, after the unmanned flying balls enter the floating stars in the shell layer of the outer galaxy, even if they are swept away with the movement of the outer galaxy shell, they will pass through the flying balls.

With the detection system on the planet, the Kuipers can still see the situation around and inside the flying ball. They can enter the outer space from the earth through the tachyon transmission system. In this way, humans will truly leave the solar system and enter.

Inner space of extraterrestrial galaxies.

This is naturally impossible in the era without the tachyon transmission system. Because if the flying ball carries people into the outer space of the outer galaxy, then as soon as it enters, it will follow the relative motion of the shell of the outer galaxy.

Being swept away, contact is lost. With the tachyon teleportation system, the problem of losing contact is solved. People on this side use the tachyon teleportation system in the flying ball to enter and exit the outer galaxy anytime and anywhere.

Inside the flying ball in space.

Qiu Siyuan and others also watched the Kuiper intersystem crossing experiment live through the display screen in their flying ball near the observatory.

"Is this where the shells of two galaxies come into contact?" Lu Tong pointed to the frightening contact vortex: "It's too scary."

"Yes, it may be 10,000 times stronger than the strong typhoons, tornadoes and vortices in rivers and seas we see on the ground." Chen Yuntian exclaimed.

On the huge display screen, the inter-system contacts follow the relative movement of the shells of the two galaxies, rolling up the floating stars in each other's shells, spinning constantly like a whirlwind. Floating stars or floating stars are often popped out from them.

The fragments enter the space between the two galaxies, that is, the inner space of the Milky Way, and instantly turn into galactic asteroids (only small dust in the large-scale universe) and leave the two galaxies.

"It's too scary." Lu Tong asked Sun Xiaogang: "How big is this vortex?"

"I'm not sure. This picture was taken from a larger floating star between the solar system shells where the vortex between the two systems is far away from the contact point. Such a large vortex is estimated to be hundreds of millions of kilometers long, right?"

"So big?" Lu Tong was stunned.

"The diameter of the solar system may be as long as two light years. How can the contact point of such a large system shell be as small as the vortex on the earth?" Sun Xiaogang disagreed.

"To use a flying ball to cross the contact point between two stars that is hundreds of millions of kilometers long, you need to fly at an astonishing speed. This may be difficult to achieve with a low-speed spacecraft." Chen Yuntian has been in contact with Sun Xiaogang for many days and has learned

There is a lot of space knowledge, so it is beyond the scope of what ordinary people in the Tang Dynasty know, and it is almost the same as the level of human beings in the previous round of earth civilization where Sun Xiaogang lived. Because officials in the Tang Dynasty all entered the officialdom through the imperial examination, although there was no way

Compared with today's college graduates, their brains are still quite flexible.

"Yes, because of this, the Kuipers used the two contacts to travel to the floating stars in the shell layer of another galaxy." Sun Xiaogang said.

"Yes," Qiu Siyuan smiled and gave Sun Xiaogang a thumbs up, agreeing: "I talked about these things with Branch Director Anderson yesterday, and he specially asked his outer space exploration expert Professor Brod Wallen to talk to you through a video call Let’s meet and answer the questions you want to know.”

"Okay." Sun Xiaogang said happily.

"When you click the "Famous Experts Discussing the Sky" button on the monitor, a screen of Professor Brod Wallen will appear. He will explain the questions you raised about the shell model of galaxies."

After listening to Qiu Siyuan's words, the people in each flying ball pressed the selection button on the display screen. Professor Brod Wallen immediately appeared on the display screen, although he was still a big-headed one with no expression. Although he is a dwarf, his voice still makes people in the flying ball feel quite friendly.

"Friends," Professor Brod Wallen said, although his face was expressionless, but because he was wearing the emotional and colorful Tang language converter specially developed by the Kuipers, his voice was full of intimacy: "What do you have to say? If you have any questions, you can ask me."

"I would like to ask," Sun Xiaogang raised his hand first and stood up and said: "The vortex at the contact point between the two shells is hundreds of millions of kilometers away, but you instead use a low-speed flying ball that travels between floating stars. What is the reason?"

"This is mainly because the distance between the two shells next to the contact vortex is too large, hundreds of millions of kilometers. No matter how fast the spacecraft is, it is impossible to pass through such a wide space in the Milky Way. It is easy to lose control during the crossing process. It is deflected by the gravity of the galactic center, and finally leaves the solar system and flies into the galactic space under the gravitational pull of the galactic center. Therefore, when we cross the galaxy, the problem is not about flying balls or flying saucers, or pointed cylinders. It is how to choose the vortex. Gravity rushes into the shell floating stars of another galaxy." Professor Brod Wallen said.

"But we know that when a vortex sweeps away people or objects, it often draws the people or objects toward the center. In other words, the people or objects are drawn into the vortex instead of rotating along the outside of the vortex." Chen Yuntian Ruo said. Said thoughtfully.

"This is exactly the problem we have been studying for many years. In fact, as early as 600 million years ago, the Kuipers had reached the outer shell of the solar system, and they had repeatedly tried to break out of the outer shell of the solar system and enter the inner space of extrasolar galaxies. .But it has never been successful." Brod Wallen nodded and said.

"So, such an experiment was done a long time ago?"

"Yes. But they all ended in failure." Professor Brod Wallen looked at the monitor in front of him with deep emotion: "We have a lot of audio and video materials in this area."

"Why is it so difficult to travel through the solar system?" Zhu Guangcai asked.

"Mainly, the solar system and the Proxima System are actually just like your Earth, except that you live inside them. Its surface is still a celestial body. However, this celestial body is floating in space within the Milky Way. That is to say , you are standing on the surface of the earth, and you are living on the surface of the solar system. The surface of the earth and the surface of the solar system are actually the same concept. In other words, they are both spherical surfaces. To be precise, you are like the surface of the solar shell. It’s a small round object swimming in an egg white-like environment, with humans living on its surface.”

"Then there should be a huge amount of space between the galaxies, so there can't be any points of contact."

"No, galaxies, their extended lines (invisible shells) are close to each other, just like fish eggs. Their distribution states are various, some are dense and close to each other. It's just that when humans observe, they feel

That's it. People on earth only regard the sun or planet as the surface of a celestial body, but regard the matter in its system as space matter, and because they cannot see it, they regard the shell of the system as space. This is actually an illusion."

"You mean, humans can't see the shell of a galaxy and treat it as space, right?"

"Yes. In fact, just like your common bird eggs, in addition to the egg shell, it has egg yolk and egg white inside. Even the inside of your earth is divided into a core and a mantle. The same goes for the solar system. The sun is actually the solar system.

It's just a shell. It's not easy for humans to break out of the solar system's shell, because they need to pass through a 'hard shell' made of floating stars tens of thousands of kilometers thick."

"why?"

"Didn't you see it? The shell contact, the large shell contact, as seen from the earth, is the same as a spiral galaxy. Do you understand?"

"I still don't quite understand." Sun Xiaogang shook his head.

"This is not difficult to understand. After all, it is difficult to see its true face without getting close to it. What people on earth see with telescopes is also far from reality. For example, many people on earth believe that there are many stars outside the solar system that are very similar to the earth.

Planets, thinking that when humans face destruction due to the sun or the earth, they can go there to live. But they rarely consider that the light of these stars outside the solar system is not the same type of light as the sun, and is not suitable for human habitation at all. Just because these stars

The light is transmitted through large-scale space, and its properties have changed."

"According to your point of view, the light emitted by each celestial body also has different types. In this way, after they enter the space in the solar system, they will be like people, climbing what mountains and singing what songs? In other words, they look similar to sunlight.

." Chen Yuntian smiled.

"The inter-system travel test has begun!" At this moment, Lu Tong pointed at the monitor and shouted.

Everyone's attention immediately focused on a large number of flying balls flying out from the floating stars on the south side of the vortex at the contact point between the two shells and flying toward the near vortex. They were quickly swept away by the vortex and disappeared without a trace.

"What kind of experiment is this?" Sun Xiaogang was stunned: "Did they throw so many flying balls into a large vortex with a diameter of hundreds of millions of kilometers and break them?"

"No, these specially made hard flying balls are equipped with tachyon transmission systems and sound and image propagation systems. Some of them are swept in by the vortex, and some are carried by the vortex to the floating stars in the opposite galaxy, and even more

What's more, some are swept back by the vortex back to the floating stars between the membranes of the solar system."

"Oh," Chen Yuntian suddenly realized: "What you mean is that you used a large number of hard flying balls to conduct experiments. As long as some of them are swept into the floating stars in the opposite system by the vortex, it will be considered a success. Because,

There is a tachyon teleportation system on it. As long as the flying ball is successfully rolled into the shell of the outer galaxy, humans can freely enter the inner space of the outer galaxy through the tachyon teleportation system."
