Liu Cixin Quotes

One night, Ye was working the night shift. 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 space. 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.

The biggest barrier to reanimating a flash-frozen body is preventing cell damage from ice crystals during the process. It's like what happens to frozen tofu: When you defrost it, it turns into a sponge. Oh, I guess most of you haven't head frozen tofu.' The expert, who was Chinese, smiled at the confused Western faces around him.

Right then, at the frequency of 12000 MHz, the sun was the brightest star in the entire Milky Way.

Unlike other human religions, they worshipped something that truly existed. Also unlike other human religions, it was the Lord who was in crisis, and the duty of salvation fell on the shoulders of the believer.

Science fiction is a literature that belongs to all humankind.

Fundamentally, Tianming was not suited to live in society, nor out of it. He lacked the ability to thrive in society, but also the resources to ignore it. All he could do was hang on to the edge, suffering. He had no idea where he was headed in life.

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.

Why not? Of the four possible sites, this has the best electromagnetic environment.” “What about the human environment? Comrades, don’t just focus on the technical side. Look at how poor this place is. The poorer a village, the craftier the people. Do you understand? If the observatory were located here, there would be trouble between the scientists and the locals. I can imagine the peasants thinking of the astronomy complex as a juicy piece of meat that they can take bites from.” This site was indeed not approved, and the reason was just what the task force leader had said.

The Archean Eon was followed by the Proterozoic Eon, each billions of years; then the Paleozoic: the Cambrian’s seventy million years, the Ordovician’s sixty million years, the Silurian’s forty million years, the Devonian’s fifty million years, the Carboniferous’s sixty-five million years, and the Permian’s fifty-five million years; then the Mesozoic: the Triassic’s thirty-five million years, the Jurassic’s fifty-eight million years, and the Cretaceous’s seventy million years; then the Cenozoic: the Tertiary’s 64.5 million years and the Quaternary’s 2.5 million years. Then humanity appeared. Compared to the eons before, mankind’s history was but the blink of an eye. Dynasties and eras exploded like fireworks; the bone club tossed into the air by an ape turned into a spaceship. Finally, this 3.5-billion-year-long road full of trials and tribulations stopped in front of a tiny human individual, a single person out of the one hundred billion people who had ever lived on the Earth, holding a red switch.

If even an extremely simple arrangement like the three-body system is unpredictable chaos, how can we have any faith in discovering the laws of the complicated universe?

But more commonly, the technique is used to construct the equivalents of pits and city walls. Some reduced-lightspeed belts are large enough to traverse an entire arm of a galaxy. In places where the stars are dense, many reduced-lightspeed black holes can be connected together into chains that stretch for tens of millions of light-years. That’s a Great Wall at the scale of the universe. Even the most powerful fleets, once trapped, would not be able to escape. Those barriers are very difficult to cross.

Real shrewdness means not letting any shrewdness show. It’s not like in the movies. The truly astute don’t sit in the shadows all day striking a pose. They don’t show off that they’re using their brains. They look all carefree and innocent. Some of them are tacky and mawkish, others careless and unserious. What’s critical is not to let others think you’re a person of interest. Let them look down on you or dismiss you and they won’t feel you’re an obstacle. You’re just a broom in the corner. The pinnacle of this is to make them not notice you at all, as if you don’t exist until the moment right before they die at your hands.

There’s a strange contradiction revealed by the naïveté and kindness demonstrated by humanity when faced with the universe: On Earth, humankind can step onto another continent, and without a thought, destroy the kindred civilizations found there through warfare and disease. But when they gaze up at the stars, they turn sentimental and believe that if extraterrestrial intelligences exist, they must be civilizations bound by universal, noble, moral constraints, as if cherishing and loving different forms of life are parts of a self-evident universal code of conduct.

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.” “Interesting, Dr. Guan, very interesting!” “Other than the speed of light, three hundred thousand kilometers per second, there’s another three-based symptom.” “What do you mean?” “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.
