In the year 206 of the Crisis Era, a year after the peace talks, the Earth Communist League expressed great concern about the three-body problem, and at the same time, due to Li Yi's research on curvature, he discovered the possibility of a curvature spacecraft reaching the speed of light.

Originally, he was ready to study the curvature of the light-speed spaceship, but Li Yi told that the curvature would leave traces in space, and it was very likely to attract those enemies who had reached the realm of light-speed spacecraft, so mankind suspended the research and development of the light-speed spacecraft, and instead studied the use of space curvature and the development of the curvature engine, but would not conduct large-scale experiments, and would only start building after getting a rough data model in the laboratory.

Although there may be some problems with the light-speed spacecraft developed in this way, there is no way to do it, and large-scale experiments are extremely dangerous.

However, in the later research and development process, there was a breakthrough in the application of curvature. It is hypothesized that a black field will be created on the path of a spacecraft with curvature, and the speed of light in the black field will be reduced, so it is possible to use this property to slow down a spacecraft that accelerates to the speed of light through orbit.

Later, after research on this problem, it was found that it was theoretically feasible, but due to the lack of research on space, it was necessary to eliminate the acceleration caused by violent deceleration. The good news is that this technique is not difficult, and in previous studies of curvature spacecraft, they have mastered such a technique.

Thus, for humans, the second way of traveling at the speed of light was discovered: using an orbital accelerator to accelerate the spacecraft to extremely close to the speed of light, and after traveling at the speed of light, a black field with a limited range of boundaries was unfolded at the destination. The speed of light in this black domain is specially set, no more than 100 meters per second, the size depends on the situation, and the thickness is generally no more than two warships.

In this way, the light-speed ship can be stopped in a very short time, saving the time that was previously used to slow down. I have to say that if the existence of Zhizi brings the three-body problem and the earth closer in communication, the development of this technology is a disguised shortening of the distance from the perspective of reality.

The previous spacecraft of the First Fleet of the Trimaran departed from the Trimaran and it took more than 400 years to reach the earth, and later passed through the orbital accelerator to save a lot of acceleration time, but because of the problem of deceleration, it still could not save time, and this journey took about 200 years.

And now, after optimizing the acceleration and deceleration phases, the journey between the Earth and the Trisomy takes less than five years! Perfectly acceptable.

At another three-body meeting, the technology was taken out and ready for construction, and the person in charge of the project showed a model at the meeting, but because the technology for the control of large black domains is not yet mature, the technology is not mature enough.

Although the theoretical prospects are promising, this technology has not yet been tested on a large scale due to the danger of the black domain and the uncontrollable nature of the black domain.

In modern society, various disciplines are interrelated, no good materials can not make good instruments, no good instruments, no precise experiments, these are all linked and closely related.

Coupled with the fact that most of today's human energy is devoted to the study of curvature lightspeed ships, which can be used without the aid of external equipment, there is little interest in this way of navigating with the help of foreign objects for the time being. It's just that the study of the black domain is also part of the curvature study, and there is a limited classification of the black domain research.

The researcher who came up with this method is called Gao Way, and he is a somewhat withdrawn person, but I have to say that he is indeed a genius.

In the end, after the project was fruitless, Gao Way had no choice but to lead his team (in fact, there were only two people: one of his beautiful girls who had a crush on him) to join the Black Domain Department of the Curvature Spaceship Research Institute to conduct research on the Black Domain.

The research includes the study of a specific light-speed black domain, with the aim of controlling the speed of light in the black domain that is formed. The study of the suppression of the black domain range, i.e. how to control the black domain from expanding, and the fixation of the black domain position. The study of the size of the black domain aims to create a black domain of the desired size of humans......

Humanity is trying to control one of the most universal and powerful weapons in the universe – the speed of light. Of course, this is only one part of the Tenth Decade Plan, and the other parts include: the directional collapse of quantum states, the study of autonomic sapients, i.e., the study of self-replicating sapients, the study of curvature, the theoretical conception of the pocket universe, the grand unified field theory, the simple and effective way to destroy galaxies, the use of the inner orbit of the solar system for light particle strikes, the study of artificial intelligence in quantum computers, and the study of the free transformation of energy and matter......

Some of them are mostly complete, and some are still theoretical. However, all of these show that the scientific level of mankind is constantly advancing to the top level of the universe.

Since Gao Way's research is not mature at present, but people believe in the idea proposed by Gao Way, so the Trisolaran is mainly studying this technology. They are also working on curvature spacecraft, but like humans, they will not conduct large-scale experiments in outer space, which will only bring disaster to the three-body problem. Therefore, after studying the theoretically usable curvature spacecraft, they focused all on the study of the controllable black domain. It is hoped that this technology will be able to be used to bring to the solar system in the future.

"Comrade 13792, I have to tell you bad news." On this day, the office of the supreme chief of the Trisolaran Star was suddenly broken into by an uninvited guest.

"What's the matter, my comrade scientific archon?" The successor of 1379, the leader who leads the Trisolarans on their way in this era, asks the scientific archon who suddenly broke in.

The Archon of Science flickered as he handed the document he was holding in his right hand to 13792, and even earthlings could see his anxious state: "The Astronomical Observatory has sent a forecast that the trajectory of our Sun No. 3 seems to have been affected by something, and after calculation, this fragile balance will be upset. Comrade 13792, we're leaving......"

No. 13792 had already quickly scanned the papers, and although his will was as hard as iron, he still asked the archon, "Has it been confirmed?" ”

"It has been confirmed, everyone has calculated more than ten times, and the final result is that there is a great possibility that the Trisolar Star will be destroyed in this 'game' of the Suns." The archon took a breath and continued to flicker: "Even if the Trisolaran grasps the fifty percent chance and is not destroyed by the sun, life will be completely gone. ”
