Part 21 (1/2)

”Don't tell anyone else. This must never happen again. Never!” Yang looked behind him to be sure there was no one at the door.

Ye nodded again.

”What's the point? The echo wave must be extremely weak, far outside the sensitivity of a conventional radio.”

”No. If my guess is right, we should get an extremely strong echo. It will be more powerful than ... I can hardly imagine. As long as the transmission power exceeds a certain threshold, the sun can amplify the signal a hundred millionfold.”

Yang looked at Ye strangely. Ye said nothing. They both waited in silence. Yang could clearly hear Ye's breath and heartbeat. He hadn't paid much attention to what she had said, but the feelings he had buried in his heart for many years resurfaced. He could only restrain himself, waiting.

Twenty minutes later, Yang picked up the phone, called the communications office, and asked a few simple questions.

He put the phone down. ”They received nothing.”

Ye let out a long-held breath and eventually nodded.

”That American astronomer responded, though.” Yang took out a thick envelope covered with customs stamps and handed it to Ye. She tore the envelope open and scanned Harry Peterson's letter. The letter said that he had not imagined that there would be colleagues in China studying planetary electromagnetism, and that he wished to collaborate and exchange more information in the future. He had also sent two stacks of paper: the complete record of the waveforms of the radio outbursts from Jupiter. They were clearly photocopied from the long signal recording tape, and would have to be pieced together.

Ye took the dozens of sheets of photocopier paper and started lining them up in two columns on the floor. Halfway through the effort she gave up any hope. She was very familiar with the waveforms of the interference from the two solar outages. They didn't match these two.

Ye slowly picked up the photocopies from the floor. Yang crouched down to help her. When he handed the stack of paper to this woman he loved with all his heart, he saw her smile. The smile was so sad that his heart trembled.

”What's wrong?” he asked, not realizing that he had never spoken to her so softly.

”Nothing. I'm just waking up from a dream.” Ye smiled again. She took the stack of photocopies and the envelope and left the office. She went back to her room, picked up her lunch box, and went to the cafeteria. Only mantou buns and pickles were left, and the cafeteria workers told her impatiently that they were closing. So she had no choice but to carry her lunch box outside and walk next to the lip of the cliff, where she sat down on the gra.s.s to chew the cold mantou.

The sun had already set. The Greater Khingan Mountains were gray and indistinct, just like Ye's life. In this gray life, a dream appeared especially colorful and bright. But one always awoke from a dream, just like the sun-which, though it would rise again, brought no fresh hope. In that moment Ye saw the rest of her life suffused with an endless grayness. With tears in her eyes, she smiled again, and continued to chew the cold mantou.

Ye didn't know that at that moment, the first cry that could be heard in s.p.a.ce from civilization on Earth was already spreading out from the sun to the universe at the speed of light. A star-powered radio wave, like a majestic tide, had already crossed the orbit of Jupiter.

Right then, at the frequency of 12,000 MHz, the sun was the brightest star in the entire Milky Way.

23.

Red Coast VI The next eight years were among the most peaceful of Ye Wenjie's life. The horror experienced during the Cultural Revolution gradually subsided, and she was finally able to relax a little. The Red Coast Project completed its testing and breaking-in phases, settling down into routine operation. Fewer and fewer technical problems remained, and both work and life became regular.

In peace, what had been suppressed by anxiety and fear began to reawaken. Ye found that the real pain had just begun. Nightmarish memories, like embers coming back to life, burned more and more fiercely, searing her heart. For most people, perhaps time would have gradually healed these wounds. After all, during the Cultural Revolution, many people suffered fates similar to hers, and compared to many of them, Ye was relatively fortunate. But Ye had the mental habits of a scientist, and she refused to forget. Rather, she looked with a rational gaze on the madness and hatred that had harmed her.

Ye's rational consideration of humanity's evil side began the day she read Silent Spring. As she grew closer to Yang Weining, he was able to get her many cla.s.sics of foreign-language philosophy and history under the guise of gathering technical research materials. The b.l.o.o.d.y history of humanity shocked her, and the extraordinary insights of the philosophers also led her to understand the most fundamental and secret aspects of human nature.

Indeed, even on top of Radar Peak, a place the world almost forgot, the madness and irrationality of the human race were constantly on display. Ye saw that the forest below the peak continued to fall to the deranged logging by her former comrades. Patches of bare earth grew daily, as though those parts of the Greater Khingan Mountains had had their skin torn off. When those patches grew into regions and then into a connected whole, the few surviving trees seemed rather abnormal. To complete the slash-and-burn plan, fires were lit on the bare fields, and Radar Peak became the refuge for birds escaping the fiery inferno. As the fires raged, the sorrowful cries of birds with singed feathers at the base never ceased.

The insanity of the human race had reached its historical zenith. The Cold War was at its height. Nuclear missiles capable of destroying the Earth ten times over could be launched at a moment's notice, spread out among the countless missile silos dotting two continents and hidden within ghostlike nuclear-powered ballistic missile submarines patrolling deep under the sea. A single Lafayette- or Yankee-cla.s.s submarine held enough warheads to destroy hundreds of cities and kill hundreds of millions, but most people continued their lives as if nothing was wrong.

As an astrophysicist, Ye was strongly against nuclear weapons. She knew this was a power that should belong only to the stars. She knew also that the universe had even more terrible forces: black holes, antimatter, and more. Compared to those forces, a thermonuclear bomb was nothing but a tiny candle. If humans obtained mastery over one of those other forces, the world might be vaporized in a moment. In the face of madness, rationality was powerless.

Four years after entering Red Coast Base, Ye and Yang married. Yang truly loved her. For love, he gave up his future.

The fiercest stage of the Cultural Revolution was over, and the political climate had grown somewhat milder. Yang wasn't persecuted, exactly, for his marriage. However, because he married a woman who had been deemed to be a counter-revolutionary, he was viewed as politically immature and lost his position as chief engineer. The only reason that he and his wife were allowed to stay on the base as ordinary technicians was because the base could not do without their technical skills.

Ye accepted Yang's proposal mainly out of grat.i.tude. If he hadn't brought her into this safe haven in her most perilous moment, she would probably no longer be alive. Yang was a talented man, cultured and with good taste. She didn't find him unpleasant, but her heart was like ashes from which the flame of love could no longer be lit.

As she pondered human nature, Ye was faced with an ultimate loss of purpose and sank into another spiritual crisis. She had once been an idealist who needed to give all her talent to a great goal, but now she realized that all that she had done was meaningless, and the future could not have any meaningful pursuits, either. As this mental state persisted, she gradually felt more and more alienated from the world. She didn't belong. The sense of wandering in the spiritual wilderness tormented her. After she made a home with Yang, her soul became homeless.

One night, Ye was working the night s.h.i.+ft. This was the loneliest time. In the deep silence of midnight, the universe revealed itself to its listeners as a vast desolation. What Ye disliked most was seeing the waves that slowly crawled across the display, a visual record of the meaningless noise Red Coast picked up from s.p.a.ce. Ye felt this interminable wave was an abstract view of the universe: one end connected to the endless past, the other to the endless future, and in the middle only the ups and downs of random chance-without life, without pattern, the peaks and valleys at different heights like uneven grains of sand, the whole curve like a one-dimensional desert made of all the grains of sand lined up in a row, lonely, desolate, so long that it was intolerable. You could follow it and go forward or backward as long as you liked, but you'd never find the end.

On this day, however, Ye saw something odd when she glanced at the waveform display. Even experts had a hard time telling with the naked eye whether a waveform carried information. But Ye was so familiar with the noise of the universe that she could tell that the wave that now moved in front of her eyes had something extra. The thin curve, rising and falling, seemed to possess a soul. She was certain that the radio signal before her had been modulated by intelligence.

She rushed to another terminal and checked the computer's rating of the signal's recognizability: AAAAA. Before this, no radio signal received by Red Coast ever garnered a recognizability rating above C. An A rating meant the likelihood that the transmission contained intelligent information was greater than 90 percent. A rating of AAAAA was a special, extreme case: It meant the received transmission used the exact same coding language as Red Coast's own outbound transmission.

Ye turned on the Red Coast deciphering system. The software attempted to decipher any signal whose recognizability rating was above B. During the entire time that the Red Coast Project had been running, it had never been invoked even once in real use. Based on test data, deciphering a transmission suspected of being a message might require a few days or even a few months of computing time, and the result would be failure more than half the time. But this time, as soon as the file containing the original transmission was submitted, the display showed that the deciphering was complete.

Ye opened the resulting doc.u.ment, and, for the first time, a human read a message from another world.

The content was not what anyone had imagined. It was a warning repeated three times.

Do not answer!

Do not answer!!

Do not answer!!!

Still caught up by the dizzying excitement and confusion, Ye deciphered a second message.

This world has received your message.

I am a pacifist in this world. It is the luck of your civilization that I am the first to receive your message. I am warning you: Do not answer! Do not answer!! Do not answer!!!

There are tens of millions of stars in your direction. As long as you do not answer, this world will not be able to ascertain the source of your transmission.

But if you do answer, the source will be located right away. Your planet will be invaded. Your world will be conquered!

Do not answer! Do not answer!! Do not answer!!!

As she read the flas.h.i.+ng green text on the display, Ye was no longer capable of thinking clearly. Her mind, inhibited by shock and excitement, could only understand this: No more than nine years had pa.s.sed since the time she had sent the message to the sun. Then the source of this transmission must be around four light-years away. It could only have come from the closest extra-solar stellar system: Alpha Centauri.34 The universe was not desolate. The universe was not empty. The universe was full of life! Humankind had cast their gaze to the end of the universe, but they had no idea that intelligent life already existed around the stars closest to them!

Ye stared at the waveform display: The signal continued to stream from the universe into the Red Coast antenna. She opened up another interface and began real-time deciphering. The messages began to show up immediately on the screen.

During the next four hours, Ye learned of the existence of Trisolaris, learned of the civilization that had been reborn again and again, and learned of their plan to migrate to the stars.

At four in the morning, the transmission from Alpha Centauri ended. The deciphering system continued to run uselessly and emitted an unceasing string of failure codes. The Red Coast monitoring system was once again only hearing the noise of the universe.
