Gravity had been pursuing Blue Space for half a century. It finally approached its target. Only three AU separated the hunter and the hunted. Compared to the 1.5 light-years that the two ships had traversed, this was mere inches.
“万有引力”号对“蓝色空间”号的追击已经持续了半个世纪，现在它已接近目标，距“蓝色空间”号只有三个天文单位了。与两舰飞过的15光年的漫长航程相比，现在可以说是近在咫尺。
Once Gravity left the Oort Cloud behind, the ship entered true outer space. From here, the sun appeared as just another star behind the ship. It lost its reality and became like an illusion. In every direction, all one could see was a bottomless abyss, and the only objects whose existence could be ascertained by the senses were the droplets flying in formation with Gravity. The droplets flanked the ship at a distance of about five kilometers, just visible to the naked eye. Those aboard Gravity liked to gaze at the droplets with telescopes as a source of comfort in the endless emptiness. Observing the droplets was, in a sense, just looking at themselves. The mirrorlike surface of the droplets reflected an image of Gravity. The dimensions were a bit distorted, but due to the perfect smoothness of the surface, the image was particularly clear. With sufficient magnification on their telescopes, the observers could even pick out the porthole, and themselves in it, in the reflection.
越过奥尔特星云后，“万有引力”号便进入了真正意义上的外太空。这时。太阳已经变成了一颗舰尾方向的普通星星，与其他的星星一样。失去了真实的存在感。仿佛是遥远虚空中的幻觉。所有的方向都是深不见底的深渊。唯一能被感官确定的实体存在就是与“万有引力”号编队飞行的水滴了。两个水滴分别位于飞船两侧五千米处，肉眼刚刚能够看到。“万有引力”号上的人们喜欢用望远镜透过舷窗看水滴，它毕竟是这无际虚空中的一个安慰。其实看水滴就是看自己，它像一面镜子，表面映出“万有引力”号的镜像虽然有些变形，但由于水滴表面的绝对光滑，镜像十分清晰，只要放大到足够的倍数，观察者甚至能清楚地看到飞船舷窗里的自己。
A decade ago, Gravity had passed through the Oort Cloud. This region, about one light-year from the sun at the edge of the Solar System, was the birthplace of comets. Blue Space and Gravity were the first human spaceships to cross this border. The region didn’t feel anything like a cloud, though. Once in a while, a frozen ball of dirt and ice — a tailless comet — passed tens of thousands or hundreds of thousands of kilometers away, invisible to the naked eye.
十年前，“万有引力”号穿过了奥尔特星云，这片距太阳1光年的彗星出没的冷寂空间被认为是太阳系最后的边界，“万有引力”，号和“蓝色空间”号是首次越过这个边界的人类飞船。当时丝毫没有穿越星云的感觉，偶尔有一颗冰冻的没有彗尾的彗星近距离掠过，也在几万几十万千米之外，肉眼根本看不到。
Most of the one hundred-plus officers and crew aboard Gravity didn’t experience this solitude because they had spent the majority of the past fifty years in hibernation. During routine cruising, only about five to ten crew members needed to be on duty. As the crew rotated through hibernation, each person was usually on duty for three to five years.
但“万有引力”号上一百多名官兵中的大部分人感觉不到这种寂寥，他们在冬眠中度过了这五十年中的大部分时间。飞船日常航行时的值班人员只有五至十人，在轮换值勤中，每人的值勤时间只有三至五年。
The entire pursuit was a complex game of acceleration between Gravity and Blue Space. First of all, Blue Space couldn’t just accelerate continuously, as doing so would cost it precious fuel and ultimately deprive it of mobility. Even if it managed to escape Gravity, it would be committing suicide in the endless empty desert of outer space if it exhausted its fuel. Although Gravity had more fuel onboard than Blue Space, it had constraints of its own. Since it needed to be prepared for a return voyage, its fuel reserves had to be divided into four equal parts: the acceleration away from the Solar System; the deceleration before its destination; the acceleration toward the Solar System; and the deceleration before arriving at the Earth. Thus, the portion available for acceleration during the pursuit amounted to only one-quarter of the fuel. Based on calculations of Blue Space’s previous maneuvers and intelligence gathered by the sophons, Gravity had an accurate idea of Blue Space’s fuel reserves, but the latter had no information about the former’s stores. Thus, in this game, Gravity knew all the cards held by Blue Space, while Blue Space struggled in ignorance. During pursuit, Gravity consistently maintained a speed higher than Blue Space, but neither ship approached their maximum velocities. Moreover, twenty-five years after the start of the chase, Blue Space stopped accelerating, perhaps because it had used up all the fuel it dared.
整个追击过程，就是 “万有引力”号和 “蓝色空间”号两舰间复杂的加速博弈过程。首先， “蓝色空间”号不可能进行无限制加速，那样会耗尽燃料，失去机动能力，即使摆脱追击，面对前方茫茫的太空荒漠也等于自杀。而 “万有引力”一号的加速也受到限制，它的燃料贮备虽然远多于 “蓝色空间”号，但要考虑返航，这样，在没有意外发生的情况下，燃料应分成四等份使用，分别是：向太阳系外加速，返航前的减速，返航向太阳系加速，到达地球前的减速。所以，能够用于追击加速的燃料只占总贮备量的四分之一。好在通过对之前航行记录的计算和智子情报， “万有引力”号能够精确掌握 “蓝色空间”号的燃料贮备量，而后者对前者的燃料情况则一无所知，所以在这场博弈中， “万有引力”号能看到 “蓝色空间”号手中的牌。反之则不行。在双方交替的加速中， “万有引力”号一直保持着高于 “蓝色空间”号的速度，但两舰的最终速度与它们能达到的最高速度都相差甚远。在追击开始后的第二十五年，也许是已经达到了燃料消耗的底线， “蓝色空间”号停止了加速。
A year previously, when Gravity and Blue Space were thirty AU apart, something not entirely unexpected occurred: Gravity and the two accompanying droplets entered a region of space where the sophons lost their quantum ties to home, terminating real-time communications with Earth. Gravity had to communicate with Earth through only neutrinos and radio. Transmissions from Gravity now took a year and three months to reach the Earth, and the ship had to wait an equally long time to receive a reply.
就在一年前，当 “万有引力”号与 “蓝色空间”号的距离缩短至三天文单位时，发生了一件并不是太意外的事：“万有引力”号和两个卜水滴进人智子盲区，与地球的实时通信中断了，只能采用电磁波和中微子通信，“万有引力”号发出的信息到达地球需要一年零三个月的时间，还要等待同样长的时问才能得到回复。
During the half century of the hunt, Gravity repeatedly hailed Blue Space, explaining that running was meaningless. Even if the crew of Blue Space somehow escaped the hunters from Earth, the droplets would catch up and destroy them. But if they returned to Earth, they would receive a fair trial. They had the option to greatly shorten the pursuit by surrendering. But Blue Space ignored these entreaties.
在半个世纪的航程中， “万有引力”号一直在呼叫 “蓝色空间”号，告诉他们逃跑没有意义，即使甩脱地球的追击战舰，水滴也肯定能追上并消灭他们；而回到地球，他们将得到公正的审判，命令他们立刻减速返航这如果实现将大大缩短追击时间，但”篮色空间“号一直没有理会。
Near the beginning of the Crisis Era, as Trisolaris sent sophons toward the Earth, it also launched six sophons at near-lightspeed to explore other regions of the galaxy.
危机纪元之初，在使用智子系统探测地球的同时，三体世界也向银河系的其他方向发射了接近光速的智子，首批发射了六个。
[Excerpt from A Past Outside of Time, More Indirect Evidence for the Dark Forest: Sophon-Blind Regions]
【摘自《时间之外的往事》黑暗森林的另一个间接证据——智子盲区】
All of these sophons soon entered blind regions and lost contact with home. The longest-lasting one managed to get seven light-years away. Additional sophons launched later met with the same fate. The closest blind region, only about 1.3 light-years from Earth, was the one encountered by the sophons that accompanied Gravity.
但这些智子不久均进入育区，最远的一个只飞行了7光年。后来发射的智子也遇到了同样的事情，最近的盲区是跟随“万有引力”号的智子遇到的，与地球的距离只有1.3光年。
Trisolaris remained mystified by the kind of interference the sophons received: Perhaps it was a natural phenomenon, or perhaps it was “man”-made. Scientists from both Trisolaris and Earth leaned toward the latter explanation.
对于智子遇到了什么样的干扰，三体世界一无所知，这种干扰可能是自然的，也可能是“人”为的；三体和地球科学家都倾向于后者。
Before being blinded, the sophons were able to explore only two nearby stars with planets. Neither system exhibited signs of life or civilization. But Earth and Trisolaris both came to the conclusion that their desolation was precisely why the sophons were allowed to approach.
飞向银河系的智于在进入盲区前。只来得及探测两个邻近的带有行星的恒星系。其中都没有生命和文明。但三体和地球的学者们都认为，那些星系的荒凉正是智子能够接近它们的原因。
Once the quantum entanglement between sophons was broken, it could not be restored. Any sophon entering a blind region was lost forever.
智子间的量子联结是一次性的，一旦中折不可能恢复，那些进入盲区的智子都永远迷失在了太空中。
Thus, even deep into the Deterrence Era, the universe at large remained hidden from the two worlds by a mysterious veil. The existence of these blind regions seemed to provide indirect proof for the dark forest nature of the universe: Something was preventing the cosmos from becoming transparent.
所以，直到威慑纪元后期，宇宙对两个世界仍保持着神秘的面纱智子盲区的存在很可能是黑暗森林状态的一个间接证据。这个状态不允许宇宙变得透明。
The captain of Gravity decided that he could no longer afford to wait. He ordered Gravity to accelerate further.
以上情况促使“万有引力”号的值勤舰长决定加快任务的进程，“万有引力”号再次提速。加快接近目标。
[Deterrence Era, Year 62, Gravity, in the Vicinity of the Oort Cloud]
【威慑纪元62年，奥尔特星云外，“万有引力“号】
As Gravity approached, Blue Space hailed the hunters for the first time, proposing a plan: Blue Space would load two-thirds of the crew — including the main suspects — onto pinnaces and send the pinnaces to Gravity if the remainder of the crew was allowed to continue their voyage into deep space aboard Blue Space. This way, a vanguard and seed for the human race would be preserved in space, keeping alive the hope for further exploration.
随着“万有引力”号的迅速逼近，“篮色空间”号第一次与追击舰联系，提出一个解决方案：把包括主要嫌疑犯在内的舰上三分之二的人员送上太空穿梭机，离开“蓝色空间”号，由“万有引力”号接收。剩下三分之一的人驾驶“蓝色空间”号继续飞向太空深处的目标。这样，人类在星际就保留了一个前哨和种子，保留了一个探索的机会。
Losing the sophons was not fatal to Gravity’s mission, though it did make the job much harder. Before, the sophons could enter Blue Space at will and report on everything that was going on; now Blue Space appeared to Gravity as a sealed box. Moreover, the droplets lost real-time communications with Trisolaris and had to rely on the onboard AI. This led to unpredictable results.
智子进入盲区对“万有引力”好的使命并没有致命的影响，但却使任务复杂了许多。之前，潜入“蓝色空间”号内部的智子，使“万有引力”号一直能够掌握目标标飞船内部的情况。现在“蓝色空间”号开始对“万有引力”号呈现黑箱状态。其次，水滴失去了三体世界的实时控制，其行为完全由内置的A.I。所控制，可能会发生意想不到的清况。
Gravity vehemently denied this request. The entire crew of Blue Space was suspected of murder, and all had to be tried. Space had transformed them until they were no longer members of the human race. Under no circumstances could they be allowed to “represent” humanity in space exploration.
这个要求被坚决拒绝。“万有引力”号声明：“蓝色空间”号上的所有人都有谋杀嫌疑，必须全部接受审判，他们是被太空异化的人。已经不被人类社会认为是自己的一部分，更不可能代表人类探索宇宙。
Gravity’s crew emerged from hibernation and readied the ship for combat. The vessel, once silent and deserted, was once again filled with people.
“万有引力”号全舰从冬眠中苏醒，战舰进人战斗状态，曾经冷清寂静了半个世纪的飞船再次充满了人气。
Those who had been awakened faced the prospect of both a target nearly at hand and the loss of real-time communications with Earth. This loss did not pull them spiritually closer to the crew of Blue Space. To the contrary, like a child who was separated from her parents, the crew distrusted the parentless wild children even more. Everyone wished to capture Blue Space as quickly as possible and return home. Even though both crews were in the cold vastness of space, voyaging in the same direction at approximately the same speed, the natures of their voyages were completely different. Gravity had a spiritual anchor, while Blue Space was adrift.
醒来的人们所面对的，除了近在眼前的追捕目标，还有与地球失去实时通信的事实。后者并未在精神上拉近他们与“蓝色空间”号的距离，恰恰相反，就像一个与父母暂时走失的孩子，对所遇到的根本没有父母的野孩子更加恐涣和不信任，所有人都希望尽快把“篮色空间”号绳之以法，然后返航。虽然两舰同处广漠冷寂的外太空，以相差不多的速度朝着同一方向航行，但在精神上，“万有引力”号与“蓝色空间”好进行的是两种截然不同的远航，前者是有源的，后者无源。
Blue Space apparently realized the futility of running and of resisting. If only a human spaceship pursued them, then they at least stood a chance if they fought. But the two droplets changed the strategic calculus. Before them, Blue Space was nothing but a paper target, and there was no chance of escape. When the two ships were only fifteen AU apart, Blue Space announced its surrender and began to decelerate at maximum power. The distance between the two ships shrank rapidly, and it seemed that the long hunt was at last coming to an end.
“蓝色空间”号显然终于意识到逃跑和抵抗都没有意义，如果追击者只有太阳系战舰，那还可以背水一战，但同行的两个水滴己经使双方的实力变得不成比例。在水滴面前，“蓝色空间”号只是一个纸糊的靶子，没有任何逃脱的可能。在双方相距十五个天文单位时，“蓝色空间”号向“万有引力”号投降，放弃逃跑，同时开始全功率减速，这使两舰的距离急剧缩短，漫长的追捕就要结束了。
“Commander, in my professional capacity, I wouldn’t laugh at anyone.”
“中校，对于我的专业来说，没什么是可笑的，一切都很正常。”
In the ninety-eighth hour after the crew’s emergence from hibernation, Dr. West, Gravity’s psychiatrist, received his first patient. This visit from Commander Devon surprised the doctor. According to his records, Devon had the highest stability score of anyone aboard. Devon was in charge of the military police aboard Gravity, and it would be his responsibility to disarm Blue Space and arrest the crew once it was caught. Gravity’s male crew members belonged to the last generation from Earth who still looked masculine, and Devon had the most masculine appearance among them. He was sometimes even mistaken for a Common Era man. He had often spoken out in favor of taking a hard line toward the suspects, suggesting that the death penalty ought to be revived.
在全体苏醒后第九十八小时，“万有弓}力”号上的心理医生韦斯特待了第一位咨询者。来人是戴文中校，这令韦斯特有些吃惊，在医生的记录中，他是舰上心理稳定系数最高的人。戴文是随舰的宪兵指挥官，负素“万有弓}力”号追上目标后，解除‘蓝色空间“号的武装并逮捕所有嫌疑犯“万有引力，号起航时，地球上的男人是最后一代像男人的男人，而戴文丈是他们中间最男性化的，他外形瓢悍，常被误认为是公元人。他经常发表一些强硬言论，认为对于黑暗战役一案，法律应该恢复死刑。
“Doctor, I know that you’ll keep my confidence,” Devon said carefully. His tone was in marked contrast to his usual hard-edged style. “I know that what I’m about to say will sound funny.”
“医生，我知道你会对听到的一切保守秘密，我也知道这很可笑。”戴文小心翼翼地说，一反他往日锋芒毕露的作风。
“The man and I passed by each other. He saluted me, and I glanced at him…”
“我与那人擦肩而过，他向我敬礼，我随意扫了他一眼……”
“What was wrong?”
“有什么不对吗？”
Devon didn’t answer the question. “Doctor, you know that as part of my duties, I’ve been monitoring the interior of Blue Space through the real-time images transmitted by the sophons. I know the crew of that ship better than I know the crew here. I know what Lieutenant Commander Park Ui-gun looks like.”
戴文井没有直接回答这个问题，“医生，你知道我的工作，我不停地通过智子发来的实时图像监视着‘蓝色空间’号内部，可以这么说：我对那里的所有人比对这里的人更熟悉，我当然认识仆义君，那个朝鲜人。”
“Yesterday, at approximately stellar time 436950, I left Conference Room Four and followed Passageway Seventeen back to my cabin. As I approached the Intelligence Center, a sublieutenant came toward me — or, at least, a man dressed in the uniform of a Space Force sublieutenant. At that time, except for crew members on duty, everyone should have been asleep. But I didn’t think it was so strange to meet someone in the passageway. Except…” Devon shook his head and his eyes lost focus, as though trying to recall a dream.
“昨天，星际时间大约是436950，我从四号会议舱出来，沿十七号舰廊回我的舱。就在舰廊中间，靠近情报中心那里，迎面走来一个人，是一名中尉，或者说穿着太空军中尉的军便装。这时除了值勤的，大部分人都睡了，不过在那里遇到一个人也没什么奇怪的，只是……”中校摇摇头，眼神恍惚起来，像是在回忆梦境。
“He was… he was the commander of the marines from Blue Space, Lieutenant Commander Park Ui-gun.”
“那个人是—是 “蓝色空间”号上的陆战队指挥官朴义君少校。”
Devon stopped again, and the doctor nodded for him to continue.
上校又停了下来，医生，飘点头示意他说下去。
“You mean Blue Space, our prey?” West’s tone was calm, betraying no hint of surprise.
“你是说’蓝色空问‘号吗？”韦斯特平静地问，没有表现出丝毫的奇感。
“No, there’s no one — I know everyone onboard. Also… after the salute, he passed by me without any expression. I stood there, stunned. But by the time I turned around, the passageway was empty.”
“本舰的人我也熟悉，没有这样的人。而且……他敬礼后从我身边走过，而无表情。我站在那里呆了儿秒钟，回头看，舰廊里已经空无一人了。”
“Maybe it was someone from our ship who looks like him.”
“也许只是舰上一个相貌相似的人。”
“When did you wake up from hibernation?”
“上七校，你是什么时候苏醒的？”
“Three years ago. I needed to keep an eye on the activities onboard our target. Before that, I was also among those aboard who had stayed out of hibernation the longest.”
“三年前，为了监视目标内部情况，我以前也是舰上苏醒时间最长的人。”
“Before that, you spent so much of your time watching those aboard Blue Space that I think you probably felt as though you were on Blue Space rather than Gravity.”
“那之前你一直看着目标飞船上的实时图像，我想在你的感觉中，自己更像是身处‘蓝色空间’号而不是‘万有引力’号。”
“Then you must have experienced the moment when we entered the sophons’ blind region.”
“那么你肯定经历了进人智子盲区的事件。”
“And then, the surveillance images were cut off. You couldn’t see anything over there anymore. And you were tired… Commander, it’s simple. Trust me: This is normal. I suggest you get more rest. We have plenty of people now to do the work that needs to be done.”
“然后，图像突然消失了，那里你什么都看不到了，同时你也很累了……上校，就这么简单，相信我，不必担心，很正常。建议你多休息，现在毕竟人手很充裕了。”
“Of course.”
“当然。”
“Yes, Doctor. I did often feel that way.”
“是的，医生，很多时间确实有这种感觉。”
“Doctor, I’m a survivor of the Doomsday Battle. After my ship exploded, I was curled up in a life pod the size of your desk, drifting in the vicinity of Neptune’s orbit. By the time I was rescued, I was close to death, but my mind was still sound, and I never suffered any delusions… I believe what I saw.” Devon got up and walked away. He turned around at the cabin door. “If I meet that bastard again — doesn’t matter where — I’m going to kill him.”
“医生，我是末日战役的幸存者，当时被爆炸抛出来，蜷缩在一个不比你这张桌子大多少的救生舱中，在海王星轨道上飘了一个月。获救时我都快死了，但心理仍没有出现问题，更没有幻觉……我相信我看到的。”戴文说着起身离开，走到舱门时他又转过身来，“再遇到那个杂种，不管在什么地方，我会杀了他。”
Some time after that, an accident happened in Ecological Area #3– a nutrient tube ruptured. The tube was made of carbon fiber, and as it wasn’t subject to pressure, the probability of a malfunction was very low. Ecological Engineer Ivantsov passed through the aeroponically grown plants, as dense as a rainforest, and saw that others had already shut off the valve leading to the ruptured tube and were cleaning up the yellow nutrient broth.
三号生态区发生了一起小事故，一根培养液管道破裂了，这是一根很坚固的碳纤维管，且不承压，发生破裂的可能性很小。维护工程师伊万穿过生态区热带雨林般的无土栽培植物，看到破裂的管道已经关闭液流，有几个人正在清理泄出的黄色培养液。
Ivantsov stopped dead when he saw the ruptured tube. “This… is caused by a micrometeoroid!”
见到管子上的破口时伊万愣住了，像见了鬼一般——“这……这是微陨石击破的！”
Someone laughed. Ivantsov was an experienced and prudent engineer, and that made his outburst even funnier. All the ecological areas were buried in the center of the ship. Ecological Area #3 was tens of meters away from the nearest section of the exterior hull.
有人笑出声来。伊万在工作上是个老成持重的人，正因为如此，他现在才显得更可笑。几个生态区都位于舰体中部，具体到三号区，距最近的舰体外壁也有几十米远。
As one, they looked up.
所有人都不约而同地抬头仰望破口上方。
“I worked more than a decade in external maintenance and I know what a micrometeoroid strike looks like! Look, you can see the typical signs of high-temperature ablation around the edges of the rupture.”
“我做过十多年的舱外维护，这种事闭上眼睛都不会弄错！你们看外爆型破口，边缘有明显的高温烧蚀，典型的微陨石击仓！”
The ceiling above the ruptured tube looked smooth and undamaged. Furthermore, above the ceiling, tens, maybe hundreds more bulkheads of various thicknesses separated this place from space. An impact-breach in any of these bulkheads would have triggered a high-level alert.
上方的舱壁光洁无损。事实上，在这道舱壁上方，与外面的太空还隔着几十道、也可能是上百道各种厚度的舱壁，这些舱壁中任何一道受到这样的撞击都会引发高级别报警。
Ivantsov closely examined the inside of the tube; then he asked a technician to cut off a ring of material around the rupture and magnify it. The chatter died down as everyone stared at the 1000x image. There were tiny black particles, a few microns in diameter, embedded in the wall of the tube. The particles twinkled like unfriendly eyes in the magnified image. They all knew what they were looking at. The meteoroid must have been about one hundred microns in diameter. It had shattered as it went through the tube, its broken pieces winding up embedded in the wall opposite the breach.
伊万把眼睛凑近破口。仔细察看破口对面的管道内壁，然后让一名技师用切割工具把管壁切下圆圆的一片，拿去显微放大。当放大一千倍的图像传来时，所有人都在震惊中沉默了。管壁上镶嵌着几个黑色的小颗粒，大小约几微米，放大后的图像中，颗粒的晶面闪闪发光，像是几只不怀好意的眸子盯着他们。这些宇航员当然都知道那是什么东西，这颗微陨石的直径约一百微米，击穿第一道管壁时自己也破碎了，已失去大部动能的碎片镶嵌在破口对面的管壁上。
“It’s like a ghost,” a sublieutenant named Ike muttered, and left. His choice of words was meaningful: About ten hours earlier, he had seen another, bigger ghost.
“见鬼了。”一位叫艾克的中尉咕浓一声，转身走开了。他这话别有含义，因为就在十几个小时前，他还见过一次更大的鬼。
Ike had been trying to fall asleep in his cabin when he saw a round opening appear in the wall opposite his bed. It was about a meter across, and occupied the space where a Hawaiian landscape had hung. It was true that many of the bulkheads on the ship could shift and transform so that doors could appear anywhere, but a circular opening like this was impossible. Moreover, the cabin walls of mid-level officers were made of metal and could not deform this way. A closer examination by Ike revealed that the edge of the opening was perfectly smooth and reflective, like a mirror.
那时，艾克正躺在自己舱室的床上昏昏欲睡，突然看到对面的舱壁上开了一个圆形的口子，直径有一米左右。挂在墙上的那幅夏威夷风景画与圆口重合的部分消失了。本来，飞船内部的许多舱壁是可变形的，可以在任何位置自动出现舱门，但并不会出现这种圆形的洞。况且中层军官宿舍的舱壁都是不可变形的金属壁。艾克细看，发现那个个圆洞的边缘像镜面一般光洁。
But the micrometeoroid had to have come from space. Based on the condition of the rupture, the micrometeoroid had struck the tube at a relative velocity of thirty thousand meters per second. It would have been impossible to accelerate the projectile to such speed from within the ship, much less from within the ecological area.
但这颗微陨石只可能来自太空，因为从创口的状态推断，微陨石与管道的相对速度高达每秒三万米。不可能在舰内把它加速到如此高的速度，更不可能在生态区里做到这点。
Although the hole was strange, Ike was rather pleased by it. Sublieutenant Vera lived next door.
这件事虽然诡异，但也是艾克求之不得的，因为为隔壁住着薇拉中尉。
Verenskaya was the AI system engineer aboard Gravity. Ike had been trying to get the Russian beauty to go out with him, but she hadn’t shown any interest. Ike still remembered his latest attempt two days ago.
薇拉是舰上的AI系统维护工几程师，那个俄罗斯美人是艾克狂热追求的对象。但薇拉对他似乎没什么兴趣。艾克还记得两天前的事情。
He and Verenskaya had just gotten off duty. As usual, they walked back to the officers’ quarters together, and as they reached Verenskaya’s cabin, Ike tried to invite himself in. Verenskaya blocked her door.
当时他和薇拉都刚结束值勤一起回到军官舱，艾克想到薇拉的舱室里坐坐，但她同没次一样，只是堵在门口和他说话。
Verenskaya looked askance at Ike. “Any real men on this ship would be too worried about our mission to think about getting into the pants of every woman around them.”
“这个舰上有尊严的男人都是忧郁的，没有心情串女人的门。”薇拉斜眼瞟着艾克说。
“Come on, sweetheart,” Ike said. “Let me in for a visit. It’s not very neighborly to never invite me over. They’ll think I’m not a real man.”
“我只是进去坐坐。你肴亲爱的。我们是邻居，我连你的门都没串过一次。你总得照顾一下男人的尊严。”艾克说。
“What’s there to worry? After we catch those murderers, there will be no more danger. Happy times will be here!”
“有什么可忧郁的？我们追上那帮杀人犯以后，世界上一切威胁都消失了，快乐的时代就要到来了。”
“They’re not murderers! Without deterrence, Blue Space would be humankind’s only hope. Yet we’re now hunting them down, allied with the enemies of the human race. Don’t you feel ashamed?”
“他们不是杀人犯！如果没有威慑。‘蓝色空间’号现在就是人类延续的唯一希望。可我们现在正和人类的敌人联手追击他们，你一点儿都不觉得耻辱？”
However, now Ike had a perfect excuse to enter Verenskaya’s cabin. He unbuckled his weightlessness belt and sat up in his bed, but stopped when he saw that the bottom half of the round opening made the top of the cabinet against the wall disappear as well. The edge of what remained of the cabinet was also perfectly smooth and reflective, like the edge of the opening itself. It was as if some invisible knife had cut through the cabinet and everything inside, including the stacks of folded clothes. The mirrorlike surface of the cross-section ran up against the edge of the round opening, and the whole reflective surface looked like a portion of the inside of a sphere.
现在，艾克可以从这个洞顺理成章地进人薇拉的舱室了。他解开失重束缚带，从床卜坐起来，但立刻停住。他看到圆洞的下方，床头柜的三分之一也消失了，那是位于圆洞前的部分，断面和圆洞的边缘一样，也是光洁晶亮的镜面，像被一把无形的利刀削掉了一样。被切断的不仅是床头柜，还有装在里面的东西，他看到一摞衣服被齐齐地切开，断茬也是亮晶晶的。整个断面与圆洞边缘吻合在一起，能看出是一个球面。
“Um… baby, if you feel this way… how did you…”
“哦，亲爱的，”艾克手指薇拉丰满的胸部说，“你这样的思想，是怎么……”
Ike pushed against the bed and lifted off in the weightlessness. Looking through the opening, he almost screamed in fright. This must be a nightmare!
艾克轻推床面，在失重中升起一点，透过圆洞向隔壁看去，立刻吓得魂飞天外，几乎肯定自己是在噩梦中。
“How did I get to join this mission? Is that what you want to say? Why don’t you go to the psychiatrist and the captain to report me? They’ll put me in forced hibernation and kick me out of the fleet after we return. That’s just my wish!” Verenskaya slammed the door in his face.
“是怎么参加这次航行的，对吗？你去心理军官和舰长那里告发我好了，我会马上被强制冬眠，回去后就被踢出军队，我求之不得呢！”薇拉说完，在艾克面前砰的一声关上了门。
Through the hole, he could see that a part of Verenskaya’s bed, pushed up against the cabin wall, had also disappeared. Verenskaya’s lower legs had been cut off. Although the cross section of the bed and the legs were also smooth and reflective, as though covered by a layer of mercury, he could see Verenskaya’s muscles and bones through it. But Verenskaya seemed all right. She was still in deep sleep, and her firm breasts slowly moved up and down as she breathed. Normally, Ike would have admired such a sight, but right now he only felt a supernatural fright. When he calmed down and looked closer, he saw that the cross-section of Verenskaya’s legs and bed also formed a spherical surface that matched the round opening.
洞的另一侧，薇拉紧靠舱壁的单人床少了一部分。躺在床上的薇拉的小腿和那部分床也一起消失了！床和腿的断面仍然是镜面，腿的断面虽然光洁无比，像涂上水银一般，但也能清晰地看到被齐齐切断的肌肉和骨骼。不过，薇拉剩下的部分好像安然无恙，她躺在那里睡得很香，丰满的胸部在均匀的呼吸中缓缓。放在平时。艾克一定会陶醉其中，但现在他只感到一种超自然的恐怖。他稍微定神细看，发现床和腿的断面也是与圆洞边缘吻合的球面形状。
He was looking at a bubble-shaped space about a meter in diameter, which erased everything within its path.
看起来这是一个直径一米左右的泡状空间，在泡内的东西全消失了。
Ike picked up a violin bow from the nightstand, and, with a trembling hand, poked it into the bubble. The part of the bow extended inside the bubble disappeared, but the bow hair remained taut. He pulled the bow back and saw that it was undamaged. But he was still glad that he hadn’t tried to go through the hole — who knew if he would emerge from the other side unharmed?
艾克从床头拿起一把提琴弓，颤抖着把弓向那个无形的空间泡伸去。果然，弓伸进泡内的部分消失了，但弓弦仍然紧绷着。他把弓抽回来，发现它完好无损。不过他仍然庆幸自己没有钻这个洞，谁知自己能不能完好无损地从另一侧出去？
So he set the sleep cap for an hour. When he woke up this time, the bubble and the hole in the wall were gone. The Hawaiian landscape was back on the wall and everything was as it was before the incident.
于是他又把催眠时间设定为一个小时，醒来后再看，圆洞消失了，舱璧依旧，那幅风景画完好无损地挂在那里，一切都与原来一样。
He woke up after half an hour, and the bubble was still there.
半小时后艾克准时醒来，看到圆洞依旧。
Ike forced himself to be calm and tried to think of the most rational explanation for the eerie sight. Then he made what he thought was a wise decision: He put on his sleep cap and lay back down on the bed. He buckled his weightlessness belt back on and set the sleep cap for half an hour.
艾克强迫自己镇静，想了想出现目前这种超自然现象的最可能的原因，然后做出了一个他自认为明智的决定：戴上催眠帽重新躺回床上。他扎紧束缚带后启动了催眠帽。把睡眠时间设定成半小时。
It took a while before the door opened, and a not-completely-awake Verenskaya demanded to know what he wanted.
门好半天才开，薇拉在门前睡眼蒙陇地问他怎么回事。
But Ike was worried about Verenskaya. He dashed out of his cabin and stopped in front of Verenskaya’s door. Instead of ringing the doorbell, he pounded on the door. His mind was filled with the terrifying vision of Verenskaya, close to death, lying on the bed with her legs cut off.
但艾克还是很担心薇拉。他冲出门去，来到薇拉的门前，没按门铃，使劲砸门，脑子里浮现的都是薇拉断了半截腿躺在床上奄奄一息的可怕画面。
“I came to see if you are… all right.” Ike’s gaze shifted down, and he saw that Verenskaya’s beautiful legs were perfect below the hem of her nightgown.
“我来看看，你……还好吗？”艾克说着向下看看，薇拉的睡裙中两条修长的美腿完好无损。
After returning to his cabin, Ike put his sleep cap on and set it for eight hours. As for what he had seen, the only wise thing to do was to shut up and say nothing. Due to Gravity’s special mission, the crew’s psychological state — especially that of the officers — was subject to constant monitoring. There was a special psychological monitoring corps aboard, comprising more than a dozen crew members out of the full complement of just over a hundred. Some crew members had wondered whether Gravity was a stellar ship or a psychiatric hospital. And then there was also the annoying civilian psychiatrist West, who thought of everything in terms of mental disorders and illnesses and blockages, until one could come to the conclusion that he would subject a clogged toilet to psychiatric analysis. The mental screening process onboard Gravity was extremely strict, and even slight mental disorders would result in the sufferer being forced into hibernation.
回到自己的舱室后，艾克又戴上催眠帽，这一次他把睡眠时问定为八个小时。对于刚才的事，唯一明智的选择就是让它烂在自己肚子里，由于，“万有引力”号的特殊性质，对舰上人员，特别是各级军官的心理监视十分严格，舰上部署了一支心理监视部队。在一百多名定员中，就有I十几名心理军官，以至于起航时有人质问，这是星际飞船还是梢神病院。再加上那个非军职的心理学家韦斯特，此人特别讨厌，把什么都归结为心理障碍和精神疾病，让人觉得马捅不通了他都能用心理理论加以分析。舰上的心理甄别标准十分苛刻，只要被认定有轻度心理障碍，就要强制冬眠。
“Idiot!” Verenskaya slammed the door shut.
“白痴！”薇拉把门猛地关上。
Ike was terrified of missing the upcoming historical encounter between the two ships. If that happened, when the ship returned to Earth in half a century, the girls back home would not see him as a hero.
那对艾克来说是一件很可怕的事，将导致他错过两舰会合的历史性时刻，如果那样，半个世纪后回到地球，他在未来女孩们的眼中将不再是英雄。
But Ike did feel a slight diminution in his dislike for the psych corps and Dr. West. He had always thought of them as making mountains out of molehills, but he had never imagined that people could suffer such realistic delusions.
但现在艾克对韦斯特和其他心理军官的厌恶感减轻了一些，以前总认为他们小题大做故弄玄虚，没想到人真的能有这样逼真的幻觉。
Compared to Ike’s minor delusion, Petty Officer Liu Xiaoming’s supernatural encounter would be considered quite spectacular.
与艾克的幻觉相比，刘晓明中士见到的超自然景象可以称得上壮观了。
Liu was performing a routine exterior hull inspection. This involved piloting a small pinnace at a certain distance from Gravity and examining the hull for any abnormalities, such as evidence of meteor strikes. This was an ancient, outdated practice no longer strictly necessary and rarely performed. The ship was full of sensors that monitored the hull continuously; any problems would be detected right away. Also, the operation could only be done when Gravity was coasting instead of accelerating or decelerating. As the ship approached Blue Space, frequent acceleration and deceleration was necessary for adjustments. This was one of those rare windows when the ship was coasting again, and Petty Officer Liu was ordered to take advantage of the opportunity.
当时，中士执行了一次舰外巡查任务，就是驾驶一艘小型太空艇，在距飞船一定距离处对它的外部进行常规检查，以期发现船体表面的异常，如陨石撞击等。这是一项古老而过时的操作，不是必须的，也很少进行。因为灵敏的传感监测系统可以随时发现舰体异常，同时这项操作只能在飞船匀速航行时进行，加速航段要做十分困难。最近，随着向“蓝色空间”号的靠近，“万有引力”号频繁地做加速和减速调整，现在终于停止加速，处于匀速航行状态，中士接到命令，借这一机会进行一次舰外巡查。
But Liu noticed something incredible: Gravity was shaped like a perfect cylinder, however, right now, its tail ended in an inclined plane! The ship was also much shorter than it should be — about 20 percent shorter, to be exact. A giant, invisible knife had cut off Gravity’s tail.
但中士很快发现了件令人难以置信的事：“万有引力”号是一个标准的圆柱体，而现在，它的尾部竟然是一个斜面！同时，中士发现舰体的长度短了许多，约有五分之一的样子，就像舰尾被一把无形的巨刀削掉了一段！
Liu piloted the pinnace out of the bay in the middle of the ship and smoothly glided away from Gravity until he was at a distance where he could see the whole ship. The giant hull was bathed in the light from the galaxy. Unlike when most of the crew was in hibernation, light spilled from all the portholes, making Gravity seem even more magnificent.
中士驾驶太空艇从舰体中部平滑地驶出“万有引力”号，在太空中滑行到能够看到飞船整体的距离。巨大的舰体沐浴在银河系的星光中，与冬眠航行时不同，所有的舷窗和外侧舰廊都透出灯光，在舰体表面形成一片灿烂的亮点，使‘万有引力“号看上去更加气势磅礴。
Liu shut his eyes, then opened them a few seconds later. The tail was still missing. He felt chilled to the bone. The giant ship before him was an organic whole. If the tail were suddenly gone, the power distribution systems would suffer a catastrophic failure, and the ship would shortly explode. But nothing of the sort was happening. The ship cruised along without trouble, as though suspended in space. No alerts of any kind came from his earpiece or were shown on his screens.
中士把眼睛闭上几秒钟，再次睁开后，看到的仍然在是尾部被削掉的“万有引力”号！顿时一股寒气穿透脊髓。这恐惧不仅是由于眼前景象的诡异，还有更实际的内容：这艘巨型星际飞船是一个有机整体，如果舰尾突然消失，能量循环系统将被完全破坏，随之而来的将是整舰的大爆炸。但现在什么都没有发生，飞船仍在平稳地航行中，看上去像绝对静止地悬在太空中一样。耳机中和眼前的系统屏幕上连最轻微的异常报譬都没有。
He pressed the switch for the intercom and got ready to give a report, but shut off the channel before saying anything. He recalled the words of an old spacer who had been at the Doomsday Battle: “Your intuition is unreliable in space. If you must act based on intuition, count from one to one hundred first. At least count from one to ten.”
中士打开通话开关，想要向上级报告，但旋即又把通话频道关上了。他想起一位参加过末日战役的老宇航员的话：“太空中的直觉是不可靠的，如果必须依靠直觉行事，就先从一数到一百，没有时间的话，也至少数到十。”
He closed his eyes and began to count. When he got to ten, he opened his eyes. The tail was still missing. He closed his eyes and continued to count, his breath coming faster now, but he struggled to remember his training, and forced himself to calm down. He opened his eyes when he reached thirty, and this time he saw the complete Gravity. He closed his eyes again, sighed, and waited until his heartbeat slowed down.
他闭上眼睛开始数。数到十时睁开眼，“万有引力”号的舰尾仍然不见踪影；他闭上眼睛继续数，呼吸急促起来，但仍努力回忆着经受过的训练，迫使自己冷静再冷静。数到三十时睁眼，终于看到了完整无缺的“万有引力”号。中士又闭上眼长出一口气，使自己剧烈的心跳稳定下来。
He piloted the pinnace to the stern of the ship, where he could see the three giant nozzles of the fusion drive. The engine wasn’t on, and the fusion reactor was kept at minimal power so that the nozzles only showed a faint red glow, reminding him of the clouds back on Earth at dusk.
然后操纵太空艇向舰尾驶去，绕到圆柱体的顶端，看到了聚变发动机二个巨大的喷口。发动机没有启动，聚变堆维持着最低功率运行，喷口只透出黯淡的红光，让他想起地球上的晚霞。
Petty Officer Liu was glad that he hadn’t made a report. An officer might get therapy, but an NCO like himself would be forced into hibernation. Like Ike, Liu Xiaoming didn’t want to return to Earth a useless man.
中士庆幸自己没有报告，军官还可能接受心理治疗。像他这样级别的士官则只能因精神问题而被强制冬眠，同艾克一样。刘晓明也不想作为一个废品回到地球。
Dr. West went to find Guan Yifan, a civilian scholar who worked in the observatory at the stern. Guan had a midship cabin assigned to him as living quarters, but he rarely went there. Most of the time, he remained in the observatory and asked the service robots to bring his meals. The crew referred to him as “the hermit at the stern.”
韦斯特医生到舰尾去找关一帆，他是一名随舰航行的学者，在设于舰尾的宇宙学观测站工作。中部生活区有分配给关一帆的生活舱，但他很少到那里住，而是长期待在观测站中，连吃饭都让服务机器人送去。人们称他为“舰尾隐士。”
The observatory was a tiny spherical cabin where Guan lived and worked. His appearance was disheveled, with an unshaven face and long hair, but he still looked relatively youthful. When West saw Guan, he was floating in the middle of the cabin, looking restless: sweaty forehead, anxious eyes, his hand pulling at his collar as if he was unable to catch his breath.
观测站只是一个窄小的球形舱，关一帆就在里面工作和生活。这人不修边幅，头发胡子老长，但看上去还是很年轻。韦斯特见到关一帆时，他正悬浮在球形舱正中，一副躁动不安的样子，额头汗湿。眼神紧张一只手不时拉扯一下已经大开的领口，好像喘不过气来似的。
“I already told you on the phone: I’m working and don’t have time for a visit.” Guan Yifan said. Obviously tired of the doctor’s arrival.
“我在工作，没时间接待你，我在电话里告诉过你的。”关一帆说。显然对医生的到来感到很厌烦。
“I’m not a member of the space force. As long as I’m no danger to the ship or the crew, you have no power over me.”
“我不是军人，只要没有威胁到飞船和他人的安全，你管不找我。”
“It’s precisely because your call betrayed signs of mental disorder that I came to see you.”
“正是在电话里，我发现你精神障碍的障碍的症状，所以来看看。”
“Fine. I’ll leave.” West turned around. “I just don’t believe that someone with claustrophobia can work in here without trouble.”
“不错，按规定我可以不管，我来是为你好。”韦斯特转身离去，“我不想醒一个患有幽闭恐惧症的人能在这种地方工作。”
“I’m not complaining. Gravity’s mission is bringing fugitives to justice, not scientific exploration. I’m grateful to have this space at all… Look, my claustrophobia has nothing to do with this.”
“我没抱怨，’万有引力‘·号的使命是执法而不是探索，起航匆匆忙忙的，能建立这个站就不错了……关键是，我的幽闭恐哄与这个无关。”
Guan called out for West to stop, but West ignored him. As he expected, Guan chased after him and stopped him. “How did you know that? I am indeed… claustrophobic. I feel like I’m being packed into a narrow tube, or sometimes squeezed between two iron plates until I’m flat as a sheet…”
韦斯特听到关一帆说让他等等，他没有理会继续离去，正如预料的那样，关一帆从后面追上来，拉住他说：“你是怎么知道的？我确实有你说的那个……幽闭恐惧症，我感到很幽闭，像被塞到一根细管子里，有时又觉得被两篇无限大的贴片压在中间，压扁了……”
“Not surprising. Look at where you are.” The doctor indicated the cabin — it resembled a tiny egg nestled in a nest of crisscrossing cables and pipes. “You research phenomena at the largest scale, but you stay in the smallest space. And how long have you been here? It’s been four years since your last hibernation, hasn’t it?”
“不奇怪，看看你待的地方。”医生指指观测站，它像是卡在纵横交错的管道和线缆中的一只小鸡蛋，“你的研究对象是最大的，可待的地方是最小的，再想想你在这里待了多长时间？你上次苏醒后已经四年没冬眠了吧？”
The doctor pulled Guan Yifan along, and the two drifted toward the bow of the ship. If the ship were accelerating, going from the stern of the ship to the bow would be equivalent to climbing up a one-kilometer well, but in the weightlessness of coasting, the trip was a lot easier. Plaza #1 was located at the bow of the cylindrical ship, under a semispherical, transparent dome. Standing there was like standing in space itself. Compared to the holographic projections of the star field on the walls of spherical cabins, this place induced an even stronger sense of the “desubstantiation effect.”
医生没再多说什么，拉着关一帆向舰首飘去。如果在加速状态下，从舰尾到舰首相当于从一千多米深的井里爬上来，但在目前匀速航行的失重状态下，去那里就很容易了。一号广场位于圆柱形舰体的头部，笼罩在一个半球形透明罩下，站在这里，几乎感觉不到半球罩的存在，仿佛置身于太空中。与球形舱中的星空全息影像相比，这里更能体会到外太空航行的“去物质效应”。
“Desubstantiation effect” was a concept from astronautic psychology. Humans on Earth were surrounded by objects, and the image of the world in their subconscious was thus material and substantial. But in deep space, away from the Solar System, the stars were only distant points of light and the galaxy was nothing more than a luminous mist. To the senses and the mind, the world lost its materiality, and empty space dominated. A space voyager’s subconscious image of the world thus became desubstantiated. This mental model was the baseline in astronautic psychology. Mentally, the ship became the only material entity in the universe. At sub-light speeds, the motion of the ship was undetectable, and the universe turned into one boundless, empty exhibition hall. Here, the stars were illusions, and the ship was the only object on display. This mental model brought with it a profound sense of loneliness, and it could cause the voyager to have subconscious delusions of being a “superobserver” toward the lone “object on display.” This feeling of being completely exposed could lead to passivity and anxiety.
“去物质效应”是宇航心理学中的一个概念。当人们身处地球世界时，周围被物质实体所围绕，潜意识中的世界图像是物质的和实体的；但在远离太阳系的外太空中，星星只是遥远的光点，银河系也只是一片发光的薄雾，从感官和心理上，世界己经失去了质量和实体感，空间主宰了一切，于是，航行者潜惫识中的世界图像由物质的变成了虚空的，这个心理模型是宇航心理学的甚本坐标。这时，在心理层面上，飞船成为了宇宙中唯一的一个物质实体。在亚光速下，飞船的运动是不可察觉的，宇宙变成了一间没有边际的空旷展厅，群星都像幻觉，飞船是唯一的展品。这种心理模型可能带来巨大的孤独感，并且很容易在潜愈识中产生对“展品”的超级观察者的幻想，进而又带来因完全暴露而产生的被动感和不安。
“Why don’t we take a walk on Plaza One? It will help.”
“我们到一号广场去散敞心吧，肯定对你有帮助。”
Thus, many of the negative psychological effects of deep-space flight were due to the extreme openness of the external environment. In West’s extensive professional experience, it was extremely rare to develop claustrophobia the way Guan Yifan did. Even stranger to West was the fact that Guan did not seem relieved by the vast, open sky of Plaza #1; the restlessness caused by claustrophobia seemed to abate not one whit. This tended to support Guan’s assertion that his claustrophobia had nothing to do with the narrow confines of his observatory. West grew even more interested in his case.
所以，外太空宇航中的负面心理因素大多是以外部环境的超开放性为基础的。而在这种环境下，关一帆竟然产生了幽闭恐惧，这在韦斯特丰富的专业经历中十分罕见。但眼前还有一件更奇怪的事：韦斯特明显看出，关一帆进人广场后，暴露于广阔太空并没有使他产生舒适的解脱感，他身上那种因幽闭产生的躁动不安似乎一点都没有减轻。这也许证明了他说过的话，他的幽闭恐惧可能真的与那狭窄的观测站无关，这使得韦斯特对他产生了更大的兴趣。
“Don’t you feel better?” The doctor asked.
“你没感觉好些吗？”医生问。
Guan glanced at the starry sky and then focused his gaze in the direction Gravity was heading. The doctor knew he was looking for Blue Space. The two ships were now only one hundred thousand kilometers apart, and coasting at approximately the same speed. At the scale of deep space, the two ships were practically flying in close formation. The leadership of both ships was in the process of negotiating the technical details of their docking. But Blue Space was still too far away to be seen with the naked eye. The droplets were invisible as well. Based on the agreement made with Trisolaris half a century ago, the droplets had shifted to a position about three hundred thousand kilometers from both Gravity and Blue Space. The two ships and the droplets formed a narrow isosceles triangle.
关一帆只是对星空扫了一眼，就望着“万有引力”号的航行方向，医生知道，他是想看到“蓝色空间”号。现在，两舰相距只有十万千米，速度基本相同，都停止加速处于匀速航行状态，以外太空的尺度可以说是在编队航行了。两舰指挥层正在就交接细节。进行最后的谈判。但在这个距离上，肉眼还是不能看到对方。水滴也看不到了，按照半个世纪前起航时与三体世界的协议，它们现在处于距两舰均为三十万千米的位置。三者的位置构成了一个细长的等腰二角形。
“No, not at all. I feel trapped. Here, everything is so… enclosed.”
“没有，一点没有，还是很幽闭，这里，这一切，都很幽闭。”
“Tell me more about this place in your dream.”
“说说你在梦中去的那个地方。”
Guan Yifan turned his gaze back to West. “Last night, I had a dream. I went somewhere, somewhere really open, open in a way that you can’t even imagine. After I woke up, reality felt very enclosed and narrow, and that was how I came to be claustrophobic. It’s like… if, as soon as you were born, you were locked inside a small box, you wouldn’t care because that was all you’ve known. But once you’ve been let out and they put you back in, it feels completely different.”
关一帆收回目光，看着韦斯特说：“昨天我做了一个梦，梦里到了一个地方，那是一个很宽敞的地方，宽敞到你不可能想象的程度。醒来后感觉现实很狭窄，就感到幽闭恐惧了。就好像，从一出生就一直把你关在一个小箱子里，也无所谓，可一旦把你放出来一次再关回去，就不一样了。”
“But you just told me it was a dream.”
“可你刚说过是在做梦。”
Guan shook his head, struggling to remember. “I don’t know if it was a dream; I don’t know if I was awake. Sometimes, you can think you’re waking from a dream, only to find yourself still dreaming; other times, you’re awake, but it seems like you’re dreaming.”
关一帆摇摇头，努川回忆着什么，“我不知道那是不是梦，也不知道那时是不是醒着。有时候，你会在梦中觉得醒来了，却发现仍在梦中；有时候，你本来醒肴，却好像在梦中。”
Guan gave the doctor a mysterious smile. “I will describe it to the other scientists on the ship, maybe even the scientists on Blue Space. But I won’t tell you. I don’t have anything against you, Doctor, but I can’t stand the attitude shared by everyone in your profession: If you think someone has a mental disorder, you treat everything he says as merely the delusion of a diseased mind.”
关一崛医生神秘地一笑，“我会对舰上的科学家说，甚至还想对’蓝色空间，号上的科学家说，但不会对你说。医生，我对你本人没有成见，但实在看不惯你们这个行业所共有的那副德性：只要你们一认定谁有精神障碍，那此人说的一切都是自己的病态幻觉。”
“The second situation is extremely rare. If you experienced that, then it was almost certainly a symptom of some mental disorder. Oh, sorry, now you’re unhappy with me again.”
“后一种情况很少见，如果在你身上发生了，就可以判定为精神障碍的症状。哦，我这么说又让你不满了。”
“No, no. I think we’re actually very similar. We both have our targets of observation. You observe the deranged, and I observe the universe. Like you, I also have some criteria for evaluating whether the observed objects are sound: harmony and beauty, in the mathematical sense.”
“不不。其实想想我们俩也有共同之处：我们都有自己的观察对象，你观察精神病人，我观察宇宙；和你一样，我也有一套判定观察对象是否健全的标准，这个标准就是数学意义上的和谐与美。”
“Why?”
“为什么？”
“But you’re wrong, Doctor.” Guan pointed at the glowing Milky Way, but his gaze remained on West, as though showing him some monster that had suddenly appeared out of nowhere. “Out there is a patient who may be mentally sound, but whose body suffers from paraplegia!”
“你错了，医生。”关一帆手指灿烂的银河。眼睛却盯着韦斯特，像在指给他看一个突然出现的巨大怪物，“它是一个高位截瘫的病人！”
“Of course the objects you observe are sound.”
“那你的观察对象显然是健全的。”
Guan curled up and hugged his knees. The movement caused his body to slowly rotate in place. The magnificent Milky Way revolved around him, and he saw himself as the center of the universe.
关一帆抱着双膝把自己缩成一团，这动作也同时使他在失重中慢慢旋转起来，他看到壮丽的银河系围绕着自己运行，自己成了宇宙中心。
“Because of the speed of light. The known universe is about sixteen billion light-years across, and it’s still expanding. But the speed of light is only three hundred thousand kilometers per second, a snail’s pace. This means that light can never go from one end of the universe to the other. Since nothing can move faster than the speed of light, it follows that no information and motive force can go from one end of the universe to the other. If the universe were a person, his neural signals couldn’t cover his entire body; his brain would not know of the existence of his limbs, and his limbs would not know of the existence of the brain. Isn’t that paraplegia? The image in my mind is even worse: The universe is but a corpse puffing up.”
“因为光速，已知宇宙的尺度是一百六十亿光年。还在膨胀中，可光速却只有每秒三十万千米，慢得要命。这意味着，光永远不可能从宇宙的一端传到另一端，由于没有东西能超过光速，那宇宙一端的信息和作用力也永远不能传到另一端。如果宇宙是一个人，就意味着他没有一个神经信号能够传遍全身，他的大脑不知道四肢的存在，四肢不知道大脑的存在，同时每个肢体也不知道其他肢体的存在，这不是截瘫病人是什么？其实我有一个比这更糟的印象，宇宙只不过是一具膨胀中的死尸1。”
“What do you mean?”
“什么？”
“Other than the speed of light, three hundred thousand kilometers per second, there’s another three-based symptom.”
“除了每秒三十万千米的光速，还有另一个‘三’的症状。”。
“Interesting, Dr. Guan, very interesting!”
“有意思，关博士，很有意思！”
“I think string theory provides an explanation.”
“弦论好像对此有所解释。”
“The three dimensions. In string theory, excepting time, the universe has ten dimensions. But only three are accessible at the macroscopic scale, and those three form our world. All the others are folded up in the quantum realm.”
“三维，在弦理论中，不算时间维，宇宙有十个维度，可只有三个维度释放到宏观，形成我们的世界。其余的都卷曲在微观中。”
“Some think that it is only when two strings encounter each other and some qualities are canceled out that the dimensions are unfolded into the macroscopic, and dimensions above three will never have such chances for encountering each other… I don’t think much of this explanation. It is not mathematically beautiful. Like I said, this is the universe’s three and three hundred thousand syndrome.”
“有人认为是两类弦相遇并相互抵消了什么东西才把维度释放到宏观，而在三维以上的维度就没有这种相遇的机会了……这解释很牵强，总之在数学上不是美的。与前面所说的，可以统称为宇宙三与三十万的综合症。
Guan laughed uproariously and put his arm around the doctor’s shoulders. “Great question! I don’t think anyone has thought this far. I’m sure there’s a root cause, and it might be the most horrifying truth that science is capable of revealing. But… Doctor, who do you think I am? I’m nothing more than a tiny observer curled up in the tail of a spaceship, and only an assistant researcher at that.” He released West’s shoulders, and, facing the galaxy, let out a long sigh. “I’ve been in hibernation the longest of anyone aboard. When we left Earth, I was only twenty-six, and even now I’m only thirty-one. But in my eyes, the universe has already transformed from a source of beauty and faith into a bloating corpse. I feel old. The stars no longer hold any attraction for me. I want to go home.”
关一帆哈哈大笑着搂住了医生的肩膀，“伟大的问题！不瞒你说，还真没人想这么远！我相信是有病因的，那可能是科学所能揭露的真相中最恐怖的一个。但……医生，你以为我是谁啊，我不过是龟缩在一艘飞船尾巴上的小小观测者，起航时只是个年纪轻轻的助理研究员。”他放开医生，对着银河长叹一声，“我是舰上冬眠时间最长的人，起航的时候我才二十六岁，现在也只有三十一，但宇宙在我眼里，已经由所有美和信仰的寄托物变成了一具膨胀的尸体……我感觉已经老了，群星不再吸引我，我只想回家。“
“What do you propose as the cause?”
“那么病因呢？”
As if in response to their conversation, the battle alert klaxons blared, sounding like the entire sky full of stars was screaming. Warning information scrolled on floating windows that appeared above the plaza. The overlapping windows sprang up one after another and quickly covered the Milky Way like colorful clouds.
像是回答他们的话，战斗警报忽然凄厉地鸣响，仿佛整个星空都在尖叫。大幅的警报信息窗口也在广场上空弹出，那些窗口层层叠叠地涌现，像彩色的乌云般很快覆盖了银河。
“Droplet attack!” West said to the confused Guan Yifan. “They’re both accelerating. One is headed for Blue Space, the other for us!”
“水滴攻击！”韦斯特对一脸茫然的关一帆说，。它们都在急剧加速，一个对准“蓝色空间”号，一个对准我们。“
Unlike Guan Yifan, West had been awake for much of the voyage. He always believed that to maintain the mental health of others, he needed to keep his own emotions under control. But something seemed to buffet his heart now, and as he reviewed his own half century of travels, his eyes moistened. “My friend, I’m old, too.”
与关一帆不同，韦斯特医生的苏醒时间很长。他一直认为，要保持别人的心理稳定，自己首先要成为有能力控制情绪的人，但现在，有什么东西冲击了他的心灵，他第一次带着感情回望半个世纪的漫长航程，双眼有些湿润了，“朋友，我也老了。”
Guan looked around, instinctively searching for something to grab on to in case the ship accelerated. But there was nothing around. In the end, he held on to the doctor.
关一帆四下看看，本能地想抓住什么东西以防飞船突然加速。但四周空无一物，最后只能抓住医生。
West held his hands. “There won’t be enough time for any evasive maneuvers. We have only a few seconds left.”
韦斯特握住他的手说：“战舰不会机动飞行的，来不及了，我们只十几秒钟了。”
They both thought of the same thing, but Guan spoke it aloud first. “Looks like neither of us needs to worry about our patients anymore.”
他们都想到同一句话，关一帆先说出来：“看来，我们都不用为自己的病人操心了。”
After a brief panic, both felt an unexpected sense of relief. They were glad that death would arrive so quickly that there wasn’t even time to be terrified. Perhaps their discussion about the universe was the best preparation for death.
短暂的惊慌后，两个人都有一种奇异的庆幸感，庆幸死亡来得如此突然，以至于根本没有时间恐惧。也许，刚才对宇宙的讨论十多死亡最好的准备。
