The Three-Body Problem

A civilization outside the human race would doubtlessly greatly attract the highly educated classes, and it was easy for them to develop many beautiful fantasies about such a civilization. The human race was a naïve species, and the attraction posed by a more advanced alien civilization was almost irresistible. To make an imperfect analogy: Human civilization was like a young, unworldly person walking alone across the desert of the universe, who has found out about the existence of a potential lover. Though the person could not see the potential lover’s face or figure, the knowledge that the other person existed somewhere in the distance created lovely fantasies about the potential lover that spread like wildfire. Gradually, as fantasies about that distant civilization grew more and more elaborate, the Redemptionists developed spiritual feelings toward Trisolaran civilization. Alpha Centauri became Mount Olympus in space, the dwelling place of the gods; and so the Trisolaran religion—which really had nothing to do with religion on Trisolaris—was born. Unlike other human religions, they worshipped something that truly existed. Also unlike other human religions, it was the Lord who was in crisis, and the duty of salvation fell on the shoulders of the believer.

The main path of spreading Trisolaran culture to society was the Three Body game. The ETO invested enormous effort to develop this massive piece of software. The initial goals were twofold: one, to proselytize the Trisolaran religion; and two, to allow the tentacles of the ETO to spread from the highly educated intelligentsia to the lower social strata, and recruit younger ETO members from the middle and lower classes.

Using a shell that drew elements from human society and history, the game explained the culture and history of Trisolaris, thus avoiding alienating beginners. Once a player had advanced to a certain level and had begun to appreciate Trisolaran civilization, the ETO would establish contact, examine the player’s sympathies, and finally recruit those who passed the tests to be members of the ETO. But Three Body didn’t attract much notice, because the game required too much background knowledge and in-depth thinking, and most young players didn’t have the patience or skill to discover the shocking truth beneath its apparently common surface. Those who were attracted by it were still mostly intellectuals.

Most of those who became Redemptionists got to know Trisolaran civilization through the Three Body game, and so Three Body could be said to be the cradle of the Redemptionists.

While the Redemptionists developed religious feelings toward Trisolaran civilization, they were also not as extreme as the Adventists in their attitude toward human civilization. Their ultimate ideal was to save the Lord. In order to allow the Lord to continue to exist, they were willing to sacrifice the human world to some degree. But most of them believed that the ideal solution would be to find a way to allow the Lord to continue to live in the Trisolaris stellar system and avoid the invasion of the Earth. Naïvely, they believed that solving the three-body problem would achieve this goal, saving both Trisolaris and the Earth. Admittedly, perhaps this thought wasn’t all that naïve. Trisolaran civilization itself had thought so through many eons. The effort to solve the three-body problem was a thread that ran through several hundreds of cycles of Trisolaran civilization. Most Redemptionists with some in-depth math and physics knowledge had attempted the three-body problem, and even after knowing that the problem was mathematically unsolvable as posed, the effort did not cease, because solving the three-body problem had become a religious ritual of their faith. Even though the Redemptionists had many first-class physicists and mathematicians, research in this area never yielded any important results. It took someone like Wei Cheng, a prodigy who had no connection to the ETO or the Trisolaran faith, to accidentally come up with a breakthrough in which the Redemptionists placed much hope.

The Adventists and the Redemptionists were always in sharp conflict. The Adventists believed that the Redemptionists were the greatest threat to the ETO. This view wasn’t without reason: It was only through some Redemptionists who had a sense of duty that the governments of the world gradually came to understand the shocking background of the ETO rebels. The two factions were of approximately equal strength within the organization, and the armed forces of both had developed to the point of starting a civil war. Ye Wenjie used her authority and reputation to try to patch over the division between the two, but the result was never ideal.
