The reason why Civilization No. 192 was described as being destroyed 400 years later was because it was discovered after the destruction of human civilization. In the novel, Civilization No. 192 had a high level of technology and a complex social structure, but due to its internal contradictions and conflicts, it eventually led to the destruction of the civilization. Therefore, the destruction of Civilization 192 happened after we discovered and studied it, not after the civilization was destroyed. Before the civilization was destroyed, part of the 192nd civilization was already destroyed, so we could only observe the process of its destruction after the civilization was destroyed.
The reason why the Three-Body Civilization was destroyed was because there was a universal law called the Dark Forest Law in the Three-Body Galaxy. This law states that civilizations in the universe will avoid contact with other civilizations as much as possible because they know that once they come into contact, they may be attacked and destroyed by other civilizations. The reason why the Three-body Civilization was called the " Three-body Civilization " was because its civilization structure was very complicated. There were three different species that depended on each other and competed with each other. This complicated civilization structure made it difficult for the Tri-body Civilization to maintain its stability and development. Therefore, it fell into a long-term war and conflict, which eventually led to the destruction of civilization. In addition, the Three-Body Civilization also faced threats from other factors such as natural disasters, climate change, energy shortage, and so on. All these factors led to the decline and destruction of the Tri-body Civilization.
In Liu Cixin's science fiction novel," The Three-Body Problem ", the Three-Body Civilization was destroyed by the Earth Civilization. In the later part of the story, a life-and-death battle was launched between the Earth civilization and the Three-Body Civilization. In the end, the Earth civilization used advanced technological weapons to destroy the Three-Body Civilization, making it impossible for the Three-Body Civilization to continue to exist.
The civilization of Three-Body No. 192 was invaded and destroyed by the Three-Body People, so the subsequent civilizations could not know if the Three-Body Problem was solvable. The previous civilizations might have had problems similar to the three-body problem. These problems might have been very complicated and required knowledge and technology from many fields to solve. When a civilization developed to a certain extent, it might begin to explore other universes and learn from other civilizations through communication. In the process, they might discover similar problems in some civilizations and try to find solutions. If a civilization found a solution, it might share the results with other civilizations so that other civilizations could solve similar problems.
Not necessarily. The civilization that destroyed the Three Bodies and the civilization that destroyed Earth belonged to different types. The Three-Body Civilization was an extraterrestrial civilization. Its attack methods and methods were very cruel and dangerous, causing the civilization of the Three-Body Galaxy to go extinct. Earth's civilization, on the other hand, was the human civilization on Earth. Although it was also attacked by alien civilizations, different civilizations had different ways of survival and adaptability, allowing Earth's civilization to survive. Therefore, the civilization that destroyed the Three Bodies was not the same civilization that destroyed Earth.
When the humans of the Three-Body Civilization were destroyed by the two-way foil, it was the end of the third stage of the Three-Body Civilization. The Three-Body Civilization was a highly developed alien civilization with a high level of technology and a complex social structure in the Three-Body Galaxy. At the same time, it also had some very unique characteristics, such as the ideology and thinking process of the Three-Body People, as well as the civilization hierarchy of the Three-Body People. Humans were one of the first civilizations that the Trisolani came into contact with. When humans were destroyed by the two-way foil, it was the end of the Trisolani civilization's third stage. In this civilization, humans had developed very advanced technology and established a relatively complex social structure. However, there were also some very unique problems and challenges, such as human understanding and understanding of the universe, as well as human morality and values.
In " Three-Body ", the " Three-Body " civilization was considered dangerous because they had highly developed technology and extraordinary abilities in space navigation. The Three-Body Civilization had advanced technology. They could detect the Earth through gravitational waves and use powerful spaceships for space exploration. This ability allowed the Three-Body Civilization to easily discover other civilizations and possibly attack them. The Three-Body Civilization had extraordinary cosmic navigation capabilities. They could travel through the dark forests of the universe and search for other civilizations on their long journey. This ability could allow the Three-Body Civilization to pose a threat to other civilizations and attack them. In summary, the advanced technology and extraordinary cosmic navigation ability of the " Three-Body " civilization made it a dangerous civilization.
In Liu Cixin's science fiction novel," The Three-Body Problem ", the original goal of the Three-Body Problem was to destroy human civilization. However, as their understanding of human civilization deepened, they began to realize the value of human civilization and tried to impart scientific and technological knowledge to the people on Earth. During this process, the Trisolar-humans discovered that the humans on Earth lacked some necessary scientific and technological knowledge, such as the laws of the Trisolar-civilization's Trisolar-motion, the laws of the Dark Forest, and so on. These knowledge were crucial to maintaining the survival and development of the Trisolar-civilization. Therefore, the Three-Body people decided to impart this scientific and technological knowledge to the people on Earth so that they could better adapt to the environment of the Three-Body civilization. In addition, the Three-Body People also believed that the Earthlings had the potential to explore the universe. Therefore, they hoped that by imparting scientific and technological knowledge to the Earthlings, the Earthlings could become a bridge for the Three-Body Civilization to communicate with other civilizations in the future and further promote the exploration and development of the universe.
In Liu Cixin's science fiction novel," The Three-Body Problem," Ye Wenjie believed that the Three-Body Civilization was superior to human civilization because it had some unique characteristics that made it stronger than human civilization in some aspects. Ye Wenjie believed that the mathematical foundation of the Three-Body Civilization was very developed. The Three-Body People used a mathematical system called the Dark Forest Method, which could accurately predict the future and make decisions quickly in unknown situations. In contrast, the mathematical foundation of human civilization was relatively weak. The mathematical system used by humans was mainly based on basic concepts such as Ethereal geometry and linear algebra. These concepts were not applicable to the Three-Body Civilization. Ye Wenjie also believed that the technological level of the Three-Body Civilization was very advanced. The Three-Body People could create powerful weapons and equipment and could carry out efficient space exploration and war. In contrast, the technological level of human civilization was relatively limited. Humans could only produce some simple weapons and equipment and lacked efficient space exploration and war capabilities. In summary, Ye Wenjie believed that the Three-Body Civilization was higher than human civilization because it had a strong mathematical foundation and scientific and technological level. These characteristics made the Three-Body Civilization stronger than human civilization in some aspects.
In " Three-Body II: Dark Forest ", the reason why the Three-Body Civilization attacked Earth was because Earth had become a " market " for the Three-Body Civilization. The civilizations on every planet in the Three-Body Galaxy would try their best to obtain sufficient resources and energy to maintain their survival and development. Therefore, the various planets in the Three-Body Civilization had established an inter-dependent relationship. This relationship was called the " Dark Forest Law." The Earth civilization was also aware of this and tried to express their existence and intentions by sending signals to the Three-Body Civilization. However, because the Trisola Civilization had already detected all civilizations in the universe, they knew about the existence of Earth and considered Earth civilization a potential threat. Therefore, Earth's civilization was seen as a " market " by the Three-Body Civilization and became a " prey " for the Three-Body Civilization. The Three-Body Civilization believed that if they did not destroy Earth's civilization as soon as possible, Earth's civilization might send more signals to other planets, causing other civilizations to discover the existence of Earth's civilization, which would lead to a greater threat to the Three-Body Civilization. Therefore, in order to protect their own survival and development, the Three-Body Civilization decided to attack Earth.
The reason why the Three-Body World was immediately destroyed was because it was detected by the existence of Earth civilization and was discovered by Earth civilization. The Three-Body World and Earth were in different locations in the universe, so the Earth civilization could not understand the Three-Body World through conventional communication and technological means. The Three-Body World could not tolerate the existence of Earth. As the civilization level of the Three-Body World was much higher than that of Earth, it had the ability to directly destroy Earth's civilization. The Earth civilization's reaction speed and technological ability were relatively slow, so the Earth civilization survived the destruction of the three-body world. However, due to the relatively low level of technology on Earth, it was unable to adapt to the environment of the Three-Body World, so it was eventually destroyed by the Three-Body World.
