According to the world view of Three-body, in the distant high-dimensional universe, life and civilization may be born before the earth. They were destroyed one by one and grew up one by one. So on the whole, although the living conditions of the three-body world are extremely bad, it is not temporary, but intermittent, and the three-body world as a whole is the cradle suitable for the birth and survival of life. Three-body civilization was born in an era older than human beings, so it is normal if their civilization is higher than human beings, and vice versa.
The urgency of knowledge acquisition of three-body civilization is much higher than that of human beings: the disaster of destroying heaven and earth has brought fatal impact to three-body civilization, and it has also made three-body civilization realize the urgency of knowledge acquisition from another angle. Just as the earth produces four seasons between red and yellow, it forces human beings to adapt to the environment, and successive disasters strive to adapt to the three-body civilization and improve themselves. As the head of the three-body said, compared with the three-body, people are flowers cultivated in the greenhouse.
Three-body civilization tried to predict three suns in various ways from primitive society in order to fight against disasters from the universe. From primitive spells to religious worship, mathematics, modern technology and so on. The history of three-body civilization can be said to be a history of struggle with heaven and earth without a moment's truce. On the other hand, because the earth has not suffered such a big disaster, human beings have become relaxed and the development of science and technology has been slow. It was not until the16th century that they got rid of the influence of religion and science sprouted.
The purpose of acquiring knowledge by three-body civilization is simpler, the research field is more direct, and the knowledge approach is more efficient: in order to face devastating disasters frequently, the purpose of acquiring knowledge by three-body civilization is simpler than that of acquiring human knowledge, in order to solve the crisis of its own survival; The research field is more direct, and other unnecessary interference is less. At the same time, there are frequent disasters in the three-body world. Although the three-body civilization paid a lot of painful prices, it also discovered many secrets of nature unconsciously, and verified the correctness of knowledge in time. If we can prove the idea and technology wrong, we will be abandoned immediately.
