Ten thousand I am across the heavens

Lan Nuo narrated the history of human beings during this period. From the beginning when human beings faced famine and Trisolarans, a large number of capitulationists appeared, and even a large number of leading parties appeared, to the later wall-facing project , Later, food synthesis technology and controllable nuclear fusion eased the crisis within human beings.

Longevity technology allows people to see the Doomsday War, and they can't help but start to really contribute their own strength to the Doomsday War in order to continue to live forever.

Later, the Trisolarans released nano-weapons, which were cracked by various human technologies one by one. Because of the assassination of Lan Nuo, they were deceived by human undercover agents to obtain a large amount of Trisolarans' technology, which greatly accelerated the process of human technology explosion. It only took a dozen In just a few years, a spaceship that could theoretically realize interstellar voyages was created.

He also jumped out of the strategic thinking of defending in the solar system, chose to take the initiative to attack, and used the accelerator to trap Sophon, and turned against the guest.We have won two years of precious time for the rapid development of science and technology.

Investigate the Trisolarans, cast a wide net in all directions, look for possible physical rules and special areas, and use these special features to defeat the Trisolarans.

Various strategies have been used so far. It can be seen that when human beings face Trisolarans, they are just bugs that are worthless for people to look at at first. Later, Trisolarans desperately want to kill a certain individual of human beings, and Now, the trisolarans have tried their best to deal with human beings, but human beings are stepping towards victory step by step.

Different from directly using deterrence to turn the world around, this kind of down-to-earth, step-by-step progress, and the experience of opening a road out of a desperate situation are extremely precious to a civilization. If I have to say, without Lan Nuo, human beings would Really can't do it?
Not necessarily!Even if accelerators cannot be used to efficiently capture sophons, it is still possible to build long-distance spacecraft carrying accelerators, each of which can take at least one sophon out of the solar system.If you really want to win a few years for the rapid development of science and technology, you may not be able to do it. After you have a certain understanding of the microcosm, it is not impossible to rely on human strength to capture sophons.

All of this is done by human beings themselves, and it may be slower, but if the whole civilization is determined to continue the struggle, even without Lan Nuo, it will only take longer to get to this step. some time.

The cemetery fell into a long silence. Although every civilization has more or less epic and shocking journeys in the process of development, such ones are definitely rare, and he couldn't help but give birth to a few It is the pride to continue to fight with this world.

In the past, they also passionately believed that they could keep the four-dimensional world, and they also sweated and worked hard for this, trying to completely curb the fall of the dimension at their level.But in the end it failed and was trapped in the only puddle.

"Okay, the transformation is almost complete. The technical details in it involve a lot of four-dimensional technology. I can talk to you later, but the four-dimensional space in this world is getting less and less, and these technologies will basically not be used in the future.

"No problem, I can announce a part to you, which has been verified by us. The two worlds have basically the same physical laws, including classical physics. I can even tell you for free that in most worlds that we can travel through In the world, the laws of mathematics and classical physics are common. Classical physics may be changed to a certain extent in some worlds, but so far I have not seen a world where the laws of mathematics are different from ours.

Graveyard seems to have finally regained the initiative in the conversation: "You will ask this question, which shows that your understanding of four-dimensional space is not deep enough.

But as the cemetery said, this technology is not too difficult. Using the materials left in the cemetery, they successfully assembled a space cutting device.

"I have to admit that you are a very tenacious civilization. Even without my appearance, I think you can rely on your own abilities to win this war. It seems that my technology is difficult to sell at a high price, but even There is no imminent survival crisis, and you must be quite eager for technology that can enhance your ability to interfere with the physical world!
Even if you can't exchange too many physical rules of other worlds, at least you can exchange which physical rules of this world are still applicable in other worlds! "

Just like the space cutting you mentioned earlier, this technology can only be realized in the four-dimensional space. I have not been to the three-dimensional world in person, so I don’t know how the three-dimensional world is cut, but cutting the four-dimensional space, for you, It is more meaningful, and it can be regarded as making the best use of our puddle that is about to dry up!
The so-called space cutting is actually to divide a piece of time and space from the universe, and then package the elementary particles to curl up in the microcosmic middle and high dimensions, just like the four-dimensional space, which can be easily packaged into the five-dimensional microcosmic particles , thus sealing up this piece of time and space, bringing out his original position.

However, the cemetery doesn't think his image is strange at all: "This is a very common form of four-dimensional creatures, and the same is true for your three-dimensional world.

The higher the dimension, the freer the space. Your observation of the microscopic world is only based on the three-dimensional world, and you will naturally come to the conclusion that time and space are extremely stable, and this conclusion is not wrong. In three-dimensional space, it is more difficult to cut space There are many, and it is not even sure whether my civilization can do this after being reduced to a lower level, and this is actually the pre-technology for opening up a private universe.

After getting along with each other for this period of time, Lan Nuo finally established a relatively complete geometric model of the four-dimensional creature of the cemetery. From the perspective of Lan Nuo as a human being, the image of the cemetery is like a tentacle monster, and it also has a shape similar to that of a human being. The torso has the same center as the brain, but the number of limbs is far more than that of humans. If it is tiled in the three-dimensional world, there are 250 or six.

Scientists have paid a lot for the continuation of civilization. It is precisely because of their existence that our civilization can retain certain four-dimensional technology even if it reduces the dimension.

In fact, when civilization collectively reduces dimensionality, some scientists use this method to preserve their own four-dimensional brains. However, due to technical limitations, the space that can be packed into an elementary particle is usually not large, even so The microcosmic particles can be brought into the three-dimensional world, and living in such a narrow four-dimensional space is like living in a cage, and it is the kind that must never leave, because leaving is death.

While transforming the space-time cutting machine, the cemetery explained to Lan Nuo the biological structure of their four-dimensional life, which is also one of the knowledge Lan Nuo urgently needs to learn.

And my current body structure is also one of the most reasonable layouts in the four-dimensional space. For us, 250 six limbs and 510 two limbs are very reasonable layouts, and they are also common to all major civilizations in the universe. Adopted life form.

This device cuts the space, and it can probably cut out a sphere with a radius of five meters in your unit. To be precise, it should not be called a sphere. Your language does not describe the equal distance to a point in the four-dimensional space. The words of the set of points, let me call him a string ball!When I mention the fourth coordinate axis in the future, I will also call it the chord, that is, the length, width and height chord.

Of course, because we have one more coordinate axis, the space is more free than the three-dimensional world, so the forms of life that will appear are more abundant than your three-dimensional world, and it is not like you, most intelligent creatures The number of limbs is so monotonous as four or six or eight. "

In the four-dimensional space, what kind of body structure is reasonable and can better deal with various situations.

Learning the mathematical model of the four-dimensional space is only the first step for him to ascend the dimension. He still needs to know what the cells in the four-dimensional space look like, and what kind of structure can replicate itself in the four-dimensional space, as the basic components of his body. exist.

The blood that surged in their hearts was just thinking about it. Now they only have a few refugees from all over the world, trapped in this pool that may dry up completely in a hundred years. There is no way to bring back what was once the ocean.

You can bring this string ball into three-dimensional space, and you can store objects in three-dimensional space in this ball, and this thing is equivalent to a portable space.

Because this is the most reasonable layout in the three-dimensional world, this is a mathematical law, as if creatures that can be sensitive to light are often symmetrical on both sides, and creatures that cannot be sensitive to light are often symmetrical to the center.

Let's collect some four-dimensional matter while our puddles haven't completely dried up!I will teach you how to process them and make them into devices that can cut time and space. With your current understanding of the microcosm, you should be able to pack the cut time and space into microcosmic particles. "

It is said that when technology develops to a certain height, it looks like magic.As the promoter of technology, Lan Nuo is the person who understands all the internal principles.It's been a long time since I've experienced this feeling of watching magic, and today I recalled this feeling of watching black technology again.

The cemetery also took a step back. The current situation is that Lan Nuo can ask for whatever price he wants. Who told him that he is not a civilization now, but just a civilized individual.

Lan Nuo nodded: "This is indeed a very meaningful technology for us, but with all due respect, is the technology that involves dividing time and space really what we can do now? Although we have limited understanding of the microcosm, the space-time The degree of stability is probably much greater than everything we can manufacture, so how can it be cut?"

This process is basically carried out by the cemetery itself, because the mass of four-dimensional matter is too large for three-dimensional people, and their propellers need countless superpositions to be able to push four-dimensional matter.

The four-dimensional space will dry up so quickly. On a certain level, it is also because the threshold of this technology in the four-dimensional space is too low. Too many civilizations have established private universes, causing the material in the universe to drain rapidly, so that the current universe It is almost impossible to avoid the ending of zero.

Even he couldn't understand the technology described in the cemetery immediately, and it took a lot of energy to figure out some of the principles.

You probably haven't seen a Trisolaran, have you?But I guess, they should also have four or six limbs, have organs that can use tools like your hands, and food also passes through their own bodies through a pipe, and then they are injected with entropy and then excreted from the other end of the pipe .

I have already shown some of my sincerity, and now it is your turn. As a creature living in the four-dimensional world, you should know some advanced technologies that are extremely difficult for us to understand. " Lan Nuo intuitively believes that the current exchange will yield huge gains.

The scientific expedition fleet was expected to assemble this equipment by themselves, but it would have to wait until the Year of the Monkey. In contrast, the cemetery's own assembly of this equipment is as simple as an ordinary repairman repairing a car.

Your controllable high-energy particles must be manufactured with the help of four-dimensional space!Then I think space cutting technology is very necessary for you. After all, the puddle we are in will eventually dry up. At that time, you will not be able to produce controllable high-energy particles. Even if you can obtain the technology of Trisolaran, It is impossible to reach the current scale after the production of sophons.

And if you can cut a part of the space here before the last puddle dries up, then you can continue to maintain the ability to produce controllable high-energy particles for a period of time after the puddle dries up. The interference ability of the material world will not decline, and technological breakthroughs can be completed calmly, getting rid of the dependence on the four-dimensional space. "

"Whether our technology is difficult to understand, I have no way of judging, after all, my current thinking mode is still a four-dimensional creature, but for your situation, there are several relatively simple technologies that can have immediate results.

I saw that you tried to use the controllable high-energy particles produced by yourself to build a ring-shaped flow of high-energy particles above your head to carry out nuclear fusion in the three-dimensional world.

This kind of fusion ring is too dangerous to place outside, and it will be affected by inertia. When you speed up or make a sharp turn, it may not be able to keep up with you and become an easy target to be destroyed. It can be placed inside the string ball, so that you can use the energy of nuclear fusion without worrying about your energy center being attacked. "

Lan Nuo felt the string ball that had been implanted inside the controllable high-energy particles, and his expression couldn't help but become weird. Why is this feeling of an extra space inside the body so familiar?Could this thing be Qihai or Dantian or something?
