The Three-Body Problem (39 page)

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.

As the ETO movement continued to develop, a third faction appeared: the Survivors. After confirming the existence of the alien invasion fleet, surviving that war became a most natural human desire. Of course, that war wouldn’t occur for another 450 years, and had nothing to do with those living today, but many people hoped that if humans
did
lose, at least their descendants who were alive in four and a half centuries could live on. Serving the Trisolaran invaders would clearly help with this goal. Compared to the other two factions, the Survivors tended to come from the lower social classes, and most were from the East, and especially from China. Their numbers were still small, but they were growing rapidly. As Trisolaran culture continued to spread, they would become a force that could not be ignored in the future.

The ETO members’ alienation developed variously from the faults of human civilization itself, the yearning and adoration for a more advanced civilization, and the strong desire for one’s descendants to survive that final war. These three powerful motives propelled the ETO movement to develop rapidly.

By then, the extraterrestrial civilization was still in the depths of space, more than four light-years away, separated from the human world by a long journey of four and a half centuries. The only thing they had sent to the Earth was a radio transmission.

Bill Mathers’s “contact as symbol” theory thus received chillingly perfect confirmation.

Two Protons

INTERROGATOR:
We will now begin today’s investigation. We hope you’ll cooperate again as you did last time.

YE WENJIE:
You already know everything I know. In fact, by now there are many things that I’d like to learn from you.

INTERROGATOR:
I don’t think you’ve told us everything. First, we want to know this: Among the messages that Trisolaris sent to Earth, what were the contents of those portions that the Adventists intercepted and withheld?

YE:
I can’t tell you. They have a tight organization. I only know that they did withhold some messages.

INTERROGATOR:
Change of subject. After the Adventists monopolized communications with Trisolaris, did you build a third Red Coast Base?

YE:
I did have such a plan. But we only built a receiver, and then construction stopped. The equipment and the base were all dismantled.

INTERROGATOR:
Why?

YE:
Because there were no more messages coming from Alpha Centauri. There was nothing on any frequency. I think you’ve already confirmed this.

INTERROGATOR:
Yes. In other words—at least as of four years ago—Trisolaris decided to terminate all communications with Earth. This makes the messages intercepted by the Adventists even more important.

YE:
True. But there’s really nothing more I can tell you about them.

INTERROGATOR:
(pausing a few seconds)
Then let’s find some topic where you can tell me more. Mike Evans lied to you, is that right?

YE:
You could put it that way. He never revealed to me the thoughts buried deep in his heart, and only expressed his sense of duty toward the other species on this planet. I never realized that this sense of duty had caused his hatred of human civilization to develop to such extremes that he could make the destruction of the human race his ultimate ideal.

INTERROGATOR:
Let’s look at the current composition of the ETO. The Adventists would like to destroy the human race by means of an alien power; the Redemptionists worship the alien civilization as a god; the Survivors wish to betray other humans to buy their own survival. None of these is in line with your original ideal of using the alien civilization as a way to reform humanity.

YE:
I started the fire, but I couldn’t control how it burnt.

INTERROGATOR:
You had a plan to eliminate the Adventists from within the ETO, and you even began to implement this plan. But
Judgment Day
is the core base and command center for the Adventists, and Mike Evans and other Adventist leaders usually reside there. Why didn’t you attack the ship first? Most of the armed forces of the Redemptionists are loyal to you, and you should have enough firepower to sink it or capture it.

YE:
It’s because of the messages from the Lord that they intercepted. All those messages are stored in the Second Red Coast Base, on some computer on
Judgment Day
. If we attacked that ship, the Adventists could erase all the messages when they realized that loss was imminent. Those messages are too important for us to risk losing them. For Redemptionists, losing those messages would be as if Christians lost the Bible or Muslims lost the Koran. I think you are faced with the same problem. The Adventists are holding the Lord’s messages hostage, and that is why
Judgment Day
has remained unmolested so far.

INTERROGATOR:
Do you have any advice for us?

YE:
No.

INTERROGATOR:
You also call Trisolaris your “Lord.” Does this mean that you’ve also developed religious feelings for Trisolaris like the Redemptionists? Are you already a follower of the Trisolaran faith?

YE:
Not at all. It’s just a habit.… I do not wish to discuss it further.

INTERROGATOR:
Let’s get back to those intercepted messages. Maybe you don’t know the exact contents, but surely you must have heard rumors of some of the details?

YE:
Probably only baseless rumors.

INTERROGATOR:
Such as?

YE:
…

INTERROGATOR:
Did Trisolaris transfer certain technologies to the Adventists, technologies more advanced than current human technology?

YE:
Not likely. Because such technology would risk falling into your hands.

INTERROGATOR:
One last question, and also the most important: Until now, has Trisolaris sent only radio waves to the Earth?

YE:
Almost true.

INTERROGATOR:
Almost?

YE:
The current Trisolaran civilization is capable of space travel at one-tenth the speed of light. This technology leap occurred a few decades ago in Earth years. Before that point, their maximum speed had hovered around one-thousandth the speed of light. The tiny probes that they sent to the Earth have not even completed one-hundredth of the journey between there and here.

INTERROGATOR:
Then I have a question. If the Trisolaran Fleet that had been launched is capable of flight at one-tenth the speed of light, it should take only forty years to reach the solar system. So why do you say that it would take more than four hundred years?

YE:
Here’s the thing. The Trisolaran Interstellar Fleet is composed of incredibly massive spaceships. Accelerating them is a slow process. One-tenth the speed of light is only their maximum speed, but they cannot cruise at this speed for long before decelerating as they approach the Earth. Also, the source of propulsion for the Trisolaran ships is matter-antimatter annihilation. In front of each ship is a large magnetic field shaped like a funnel to collect antimatter particles from space. This collection process is slow, and only after a long wait can it gather enough antimatter to allow the ship to accelerate for a brief period. Thus, the fleet’s acceleration occurs in spurts, interspersed by long periods of coasting to collect fuel. This is why the time it takes the Trisolaran Fleet to reach the solar system is ten times longer than the flight time of a small probe.

INTERROGATOR:
Then what did you mean by “almost” just now?

YE:
We’re talking about the speed of space flight within a certain context. Outside this context, even backward human beings are capable of accelerating certain objects to close to the speed of light.

INTERROGATOR:
(a pause)
By “context,” do you mean at the macro scale? At a micro scale, humans can already use high-energy particle accelerators to speed up subatomic particles to near the speed of light. These particles are the “objects” you meant, correct?

YE:
You’re very clever.

INTERROGATOR:
(points to his earpiece)
I have the world’s foremost scientists behind me.

YE:
Yes, I meant subatomic particles. Six years ago, in the distant Trisolaran stellar system, Trisolaris accelerated two hydrogen nuclei to near the speed of light and shot them toward the solar system. These two hydrogen nuclei, or protons, arrived at the solar system two years ago, then reached the Earth.

INTERROGATOR:
Two protons? They only sent two protons? That’s almost nothing.

YE:
(laughs)
You also said “almost.” That’s the limit of Trisolaran power. They can only accelerate something as small as a proton to near the speed of light. So over a distance of four light-years, they can only send two protons.

INTERROGATOR:
At the macroscopic level, two protons are nothing. Even a single cilium on a bacterium would include several billion protons. What’s the point?

YE:
They’re a lock.

INTERROGATOR:
A lock? What are they locking?

YE:
They are sealing off the progress of human science. Because of the existence of these two protons, humanity will not be able to make any important scientific developments during the four and a half centuries until the arrival of the Trisolaran Fleet. Evans once said that the day of arrival of the two protons was also the day that human science died.

INTERROGATOR:
That’s … too fantastic. How can that be?

YE:
I don’t know. I really don’t know. In the eyes of Trisolaran civilization, we’re probably not even primitive savages. We might be mere bugs.

It was near midnight by the time Wang Miao and Ding Yi walked out of the Battle Command Center. They had been invited to listen to Ye’s interrogation due to Wang’s involvement in the case and Ding Yi’s connection to Ye’s daughter.

“Do you believe what Ye Wenjie said?” Wang asked.

“Do you?”

“Many things that have happened recently are incredible. But for two protons to block all progress of human science? That seems…”

“Let’s focus on one thing first. The Trisolarans were able to shoot two protons at the Earth from four light-years away and they both reached the target! That accuracy is incredible! There are numerous obstacles between there and here: interstellar dust, for example. And both the solar system and the Earth are moving. It would require more precision than shooting a mosquito here from Pluto. The shooter is beyond imagination.”
