Byzantium was a thousand-year rut behind the wheels of Ancient Rome, and though it enjoyed splendor for a time, it finally evaporated like a water stain under the bright sun. Once, ancient Romans had whistled in their grand, magnificent baths, thinking that their empire, like the granite that made up the walls of the pools in which they floated, would last forever. No banquet was eternal. Everything had an end. Everything.
comment, but you’re wrong about the environment on Earth. The Earth gave birth to life, but life also changed the Earth. The current environment on our planet is the result of interactions between the two.” He grabbed the mouse and started clicking. “Let’s do a simulation.”
“Do you think life is nothing but a fragile, thin, soft shell clinging to the surface of this planet?”
“Only if you neglect the power of time. If a colony of ants continue to move clods the size of grains of rice, they could remove all of Mount Tai in a billion years. As long as you give it enough time, life is stronger than metal and stone, more powerful than typhoons and volcanoes.”
Of course, the star he saw and the star she would see were only an image from 286 years ago. The faint beam of light had to cross three centuries to meet their retinas. Another 286 years would have to pass before the light from the star at this moment would reach the Earth. By then, Cheng Xin would long have turned to dust.
The troubles brought about by hibernation, on the other hand, were practical, and affected the entire human race. Once the technology was successfully commercialized, those who could afford it would use it to skip to paradise, while the rest of humanity would have to stay behind in the comparatively depressing present to construct that paradise for them.
Cheng Xin, on the other hand, wanted him to suffer in eternity. Tianming was terrified of space. Like everyone who studied spaceflight for a living, he understood space’s sinister nature better than the general public. Hell was not on Earth, but in heaven.
When humanity finally learned that the universe was a dark forest in which everyone hunted everyone else, the child who had once cried out for contact by the bright campfire put out the fire and shivered in the darkness. Even a spark terrified him.
Similarly, when humans truly enter space and are freed from the Earth, they cease to be human. So, to all of you I say this: When you think about heading into outer space without looking back, please reconsider. The cost you must pay is far greater than you could imagine.
But, in our age, conscience and duty are not ideals: an excess of either is seen as a mental illness called social-pressure personality disorder. You should seek treatment.”
Trisolarans produced sophisticated, high-quality art. Scholars called this phenomenon cultural reflection. Human civilization now possessed a mirror in the universe, through which humanity gained a new understanding of itself through a novel perspective.
The power of religions also recovered, and people gathered into different faiths and churches. Thus, theocracy, a zombie even more ancient than totalitarianism, reanimated itself.
Death is the only lighthouse that is always lit. No matter where you sail, ultimately, you must turn toward it. Everything fades in the world, but Death endures.”
The child that was human civilization had opened the door to her home and glanced outside. The endless night terrified her so much that she shuddered against the expansive and profound darkness, and shut the door firmly.
There was a saying: If there really were a Creator, the only thing He welded shut in all Creation was the speed of light.
She looked at the golden bandoliers hanging over the chests of every soldier: These were the chains of the god of Death. A single bandolier possessed enough power to destroy the entire Bunker World.
Recall the great law of reversible discovery: If you could see a low-entropy world, then that low-entropy world could also see you—it was only a matter of time. Thus, waiting for others to complete cleansing was dangerous.
She avoided life by staying outside of time, and she watched as others aged, seemingly in an instant. Her heart was filled with regret and guilt. She decided that no matter what happened from now on, this was her last hibernation.
Weakness and ignorance are not barriers to survival, but arrogance is.
There really didn’t seem to be any point in insisting. Even if Luo Ji got on Halo, it would only delay the inevitable by another hour. He didn’t need that bit of time.
But the immensity of the planets did not give them any sense of substantiality. Rather, they looked like whirlpools in space-time. In the universe, every part of space flowed, churned, trembled between madness and horror like fiery flames that emitted only frost. The Sun and the planets and all substance and existence seemed to be only hallucinations produced by the turbulence of space-time.
Luo Ji nodded. Cheng Xin thought the way he looked at her was no longer kind, but rather resembled the fires of the Last Judgment. His gaze seemed to say, Child, look at what you’ve done. Cheng Xin now understood that of the three paths of survival presented to humanity—the Bunker Project, the Black Domain Plan, and lightspeed ships—only lightspeed ships were the right choice.
“I can see that. The moment I entered lightspeed, I felt myself change. I realized that I could, in my lifetime, leap across space-time and reach the edge of the cosmos and the end of the universe. Things that used to seem only philosophical suddenly became concrete and practical.”
“Yes. Things like the fate and goal of the universe used to be only ethereal concerns of philosophers, but now every ordinary person must consider them.”
Their goal is to leap across time using relativity until they reach the heat death of the universe. By their calculations, ten years within their frame of reference would equal fifty billion years in ours.
“I wonder what their life here was like?” Cheng Xin asked, tears glistening in her eyes. “Anything was possible,” said Yifan. “Did they have children?” “Anything was possible. They could have even founded a civilization here.” Cheng Xin knew that was indeed possible. But even if that civilization had lasted ten million years, the eight million-plus years that had come after would have erased all traces of it. Time really was the cruelest force of all.
In the eternal night of the Orion Arm of the Milky Way Galaxy, two civilizations had swept through like two shooting stars, and the universe had remembered their light.
The ultimate fate of all intelligent beings has always been to become as grand as their thoughts.
