In fact, Li Yu still has a lot of questions about Luo and Muka civilization, but the main ones have been answered, and the other small questions can be found by looking at the information by looking back, otherwise it is okay to let Xiao Wei answer slowly. Pen % fun % Pavilion www.biquge.info

The most important thing now is to figure out where Space is in the universe right now.

In order to determine the position of the universe, the calculation of the stars is never a simple matter, at least before Li Yu has developed a new positioning method, it is necessary to determine the position by calculating the star map.

"The calculations are out!" Xiao Wei and Mo Ya glanced at each other and were very happy.

A huge image of the starry sky was projected by Xiao Wei, and the location of the space number was specially marked, but on this map, the solar system could not be seen, and even the Milky Way was invisible.

"We're at least 30 million light-years away from the Milky Way, and if we hadn't stopped observing the universe with deep-sky telescopes, we wouldn't even know where we were." Xiao Wei is very happy.

The local group of galaxies is only a small dot on the star map, which indicates that the space number is far away from the Milky Way. The solar system is part of the Milky Way, the Milky Way is part of the local group of galaxies, and the local group of galaxies is only part of the local supercluster.

The Supercluster is about 200 million light-years away, and the Milky Way is located at the edge of the Supercluster. These are part of the knowledge of scientists on Earth about the universe. Earth scientists divide the sky into three regions, and the concept of this region is different from the concept of the main civilization in the universe.

In the previous concept, the supercluster is already extremely extensive, but the supercluster will still be clustered together by a single center of mass. Geoscientists believe that the supercluster is the next level of the total galaxy, and this conclusion is due to technical and theoretical limitations.

In fact, superclusters of galaxies can also have convergent phenomena due to the gravitational pull of a center of mass, but this phenomenon is not obvious on a cosmic scale.

The so-called celestial region of the celestial region of the celestial region is the aggregation of superclusters, and the upper level of the celestial region is the total galaxy.

The Milky Way is located at the edge of the two celestial regions, and the location of the space number is basically out of the celestial region of the Quinn civilization.

"We're not safer here!" Li Yu didn't feel glad, if the Quinns' rule over the realm was in a state of herding, the surveillance on this side of the frontier would be stronger, and it would be better to stay in the galaxy here.

Xiao Wei understood what Li Yu meant, and the others present also understood that it seemed that the space number needed to open the high-dimensional window again.

However, the window that opens again leads there, and the risk is uncontrollable.

"The Quinns' monitoring of the territory is not all-encompassing, and the information provided by Luo shows that the boundaries of the four celestial district-level civilizations are not actually adjacent, and there are many star clusters in between. By sailing along these clusters, you can avoid surveillance. ”

"The important thing is that the frontier monitoring of the Celestial Civilizations is mainly aimed at the Celestial Civilizations, and it is basically an attitude of ignoring the general civilizations."

"This is not because of the carelessness of the Celestial Zonal-level civilization, but because, if it is not a Celestial-Zonal-level civilization, it is basically impossible to cross the galaxy range of the frontier. Sailing across the open zone is not easy to hide. ”

Lin Wanbai was very happy: "In other words, as long as we are careful, we can sail freely?" ”

"There's nothing wrong with that, basically."

Fang Qianmo became interested, "Xiao Wei, how does the Heaven Zone-level civilization divide the navigation technology of the spaceship?" What is the level of high-dimensional space technology we use now? ”

"In fact, high-dimensional space technology is not the mainstream technology for celestial-level civilization navigation. In the technological classification of the celestial civilization, high-dimensional space technology is nothing more than patrol-level technology, which is mainly used on small spacecraft for ordinary patrols. ”

"High-dimensional space technology, faster than the speed of light, this is the standard technology of the patrol level. Due to its particularity, high-dimensional space technology is not suitable for ultra-long-distance navigation. ”

When Xiao Wei said this, he stopped and looked at Li Yu, and Li Yu understood after a little thought: "The problem of losing the coordinates, right?" ”

"That's right, there is no connection between the distance in high-dimensional space and the distance in three-dimensional space, which has advantages and disadvantages. After the Muka people came to a research conclusion, they did not make great efforts to develop high-dimensional space technology, and that conclusion is that the coordinates of three-dimensional space mapped in high-dimensional space are not fixed, and every time they open high-dimensional space, they will change. ”

"There must be a limit to this change, otherwise the high-dimensional space technology would not still be in use!" Lin Wanbai is very sure of this.

"Gu Xiu's technical information, my database has, it's too complicated to talk about in detail, if you are interested, read it yourself. I'll just briefly say that it has to do with very large mass points. ”

The defects of the high-dimensional space technology that Xiao Wei mentioned had never been encountered by Li Yu before, mainly because his range of activities has always been very small, unlike the Tianqu-level civilization, where people's range of activities starts at 100 million light years.

"I didn't think about it, I always thought that high-dimensional space technology was the best technology for traveling across river systems!" Xiao Wei's words made Fang Qianmo also surprised.

Lin Wanbai's brain suddenly opened: "It turns out that high-dimensional space technology is an excellent escape technique!" ”

Everyone was stunned for a moment, and then reacted, isn't it, high-dimensional space technology is really an excellent technique for escape, and if the 17th also knew high-dimensional space technology, he would have escaped a long time ago.

"That's not right! With this technique, Luo didn't avoid the pursuit of the Quinns a long time ago! Fang Qianmo reacted to something.

"It's not that Luo doesn't want to use it, it's that he can't escape. Related to spatial coordinate mapping, the distance that high-dimensional space technology can leave at one time cannot exceed 50 million light years. ”

"The randomness of high-dimensional space technology is only within this range. After exceeding this range, the energy required to open the window is too terrifying, and the energy used by the Heaven Zone-level civilization is not enough to support the need. ”

Li Yu suddenly realized: "This is the reason why this technology cannot be applied to advanced spaceships!" ”

"That's right!"

A flash of inspiration flashed in Lin Wanbai's mind: "Is it possible that the energy consumption of high-dimensional space technology in this range is less than that of space jumping?" So the space jumping technology is not equipped on the spacecraft of this class? ”

"There are reasons for this, and another reason is that since it is a patrol, it is not suitable to jump in space, and it is easy to miss a lot of places."

Xiao Wei's words everyone understood as soon as they thought about it, the space jump engine that Li Yu had researched had reached 1,500 light years, not to mention that it was much inferior to the Heaven Region-level civilization, even compared to the cross-river system-level civilization. Jumping tens of thousands of light-years at a time, this is not a patrol but a rapid march.

Therefore, it is most appropriate to use faster-than-light speed with high-dimensional space technology.

Of course, these technologies are not the only ones in this universe, there are many strange space technologies, after all, the civilizations in the universe are as numerous as the sea of stars, but these technologies have not developed into mainstream technologies.

Xiao Wei continued: "The upper level is the addition of space jumping technology, and with this technology, the range of activity of the spacecraft is greatly enhanced. Different civilizations have different technical parameters for space leaps. The technical parameters of the Celestial Zone-level civilizations are all similar, and the other civilizations are uneven. ”

"Of course, there are different ways to jump in space. The technology of the Celestial Civilizations is the top, because their research on energy is more in-depth, so they can support higher-level technologies. ”

"The most advanced technology involves time, and the one used should be called space-time jumping, but I think Li Yu's spatial teleportation is very similar to their space-time jump."

"That's the general situation of astronautical technology in the universe."

Li Yu: They were eye-opening, and of course they were even more proud that the space teleportation technology of the laboratory was faintly more advanced than the technology of the Heaven Zone-level civilization.

Li Yu himself even thinks that if it weren't for the fact that the supporting technology had not been developed, then the current space teleportation technology in the laboratory would have been able to replace the current technology long ago, and it would be random to leave the galaxy this time, and if you don't want to go there, you can go there.

You must know that a long time ago, Li Yu teleported in a space, and if he didn't use mana, he would go ten thousand light years, and if he used mana, Li Yu hadn't tried it yet.

However, I believe that it is far away.
