Liu Cixin Quotes

Humanity is a dewdrop on the great tree of the universe. During its brief life span, it absolutely cannot perceive the maturing of the great tree.

Of course she's not afraid. She knows that the sun will rise again tomorrow.

Those whose courses are different cannot lay plans for one another.

The whole universe is in darkness, but we remain lit. We're a tiny bird tied to a branch in the dark forest, with a spotlight trained on on us.

"A newly formed planet appeared on the large screen. its surface was till red-hot, like a piece of charcoal fresh out of the furnace. Time passed at the rate of geological eras, and the planet gradually cooled. The color and patterns on the surface slowly shifted in a hypnotic manner. A few minutes later, an orange planet appeared on the screen, indicating the end of the simulation run.

"The computations were done at the coarsest level; to do it with more precision would require over a month." Green Glasses moved the mouse and zoomed in on the surface of the planet. The view swept over a broad desert, over a cluster of strangely shaped, towering mountain peaks, over a circular depression like an impact crater.

"What are we looking at?" Yang Dong asked.

"Earth. Without life, this is what the surface of the planet would look like now."

"But . . . where are the oceans?"

"There are no oceans. No rivers either. The entire surface is dry."

"Your'e saying that without life, liquid water would not exist on Earth?"

"The reality would probably be even more shocking. Remember, this is only a coarse simulation, but at least you can see how much of an impact life had in the present state of the Earth."

"But — "

"Do you think life is nothing but a fragile, thin, soft shell clinging to the surface of this planet?"

"Isn't it?"

"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.

Mind you, what we are discussing isn’t religion, per se, but religious feeling. This isn’t the feeling someone has toward God—it’s atheistic, and not in the complicated way of Spinoza or whomever. The religious feeling of science fiction is a deep sense of awe at the great mysteries of the universe.

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.

Everything you see before you is the result of poverty. But how are things any better in the wealthy countries? They protect their own environments, but then shift the heavily polluting industries to the poorer nations.

Information technology advances in great strides. Except for those lucky enough to climb into management, everyone’s knowledge and skills grow obsolete quickly.

I created a sphere in this infinite space for myself: not too big, though possessing mass. My mental state didn’t improve, however. The sphere floated in the middle of “emptiness” — in infinite space, anywhere could be the middle. The universe had nothing that could act on it, and it could act on nothing. It hung there, never moving, never changing, like a perfect interpretation for death. I created a second sphere whose mass was equal to the first one’s. Both had perfectly reflective surfaces. They reflected each other’s images, displaying the only existence in the universe other than itself. But the situation didn’t improve much. If the spheres had no initial movement — that is, if I didn’t push them at first — they would be quickly pulled together by their own gravitational attraction. Then the two spheres would stay together and hang there without moving, a symbol for death. If they did have initial movement and didn’t collide, then they would revolve around each other under the influence of gravity. No matter what the initial conditions, the revolutions would eventually stabilize and become unchanging: the dance of death. I then introduced a third sphere, and to my astonishment, the situation changed completely. Like I said, any geometric figure turns into numbers in the depths of my mind. The sphereless, one-sphere, and two-sphere universes all showed up as a single equation or a few equations, like a few lonesome leaves in late fall. But this third sphere gave “emptiness” life. The three spheres, given initial movements, went through complex, seemingly never-repeating movements. The descriptive equations rained down in a thunderstorm without end. Just like that, I fell asleep. The three spheres continued to dance in my dream, a patternless, never-repeating dance. Yet, in the depths of my mind, the dance did possess a rhythm; it was just that its period of repetition was infinitely long. This mesmerized me. I wanted to describe the whole period, or at least a

Let’s turn the kindness we show toward the stars to members of the human race on Earth and build up the trust and understanding between the different peoples and civilizations that make up humanity. But for the universe outside the solar system, we should be ever vigilant, and be ready to attribute the worst of intentions to any Others that might exist in space. For a fragile civilization like ours, this is without a doubt the most responsible path.

The experience of high-dimensional spatial sense was a spiritual baptism. In one moment, concepts like freedom, openness, profundity, and infinity all gained brand-new meanings.

No banquet was eternal. Everything had an end. Everything.

The assembly fell into a prolonged silence. Ahead of them stretched the leaden road of time, terminating somewhere in the mists of the future, where all they could see were flickering flames and luster of blood. The brevity of a human lifespan tormented them as never before, and their hearts soared above the vault of time to join with their descendants and plunge into blood and fire in the icy cold of space, the eventual meeting place for the souls of all soldiers.

The stern of the ship faced the Solar System, where the sun was by now no more than a yellow star just a bit brighter than the rest. The peripheral spiral arm of the Milky Way lay in this direction, its stars sparse. The depth and expanse of deep space exhibited an arrogance that left no support for the mind or the eyes. “Dark. It’s so fucking dark,” the captain murmured, and then shot himself.
