Liu Cixin Quotes

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.

In this forest, hell is other people. An eternal threat that any life that exposes its own existence will be swiftly wiped out. This is the picture of cosmic civilization. It’s the explanation for the Fermi Paradox.

Of course, I’ve only brought up two examples. Other universal laws of physics have been used as weapons as well, though we don’t know all of them. It’s very possible that every law of physics has been weaponized. It’s possible that in some parts of the universe, even … Forget it, I don’t even believe that.” “What were you going to say?” “The foundation of mathematics.” Cheng Xin tried to imagine it, but it was simply impossible. “That’s … madness.” Then she asked, “Will the universe turn into a war ruin? Or, maybe it’s more accurate to ask: Will the laws of physics turn into war ruins?” “Maybe they already are.… The physicists and cosmologists of the new world are focused on trying to recover the original appearance of the universe before the wars more than ten billion years ago. They’ve already constructed a fairly clear theoretical model describing the pre-war universe. That was a really lovely time, when the universe itself was a Garden of Eden. Of course, the beauty could only be described mathematically. We can’t picture it: Our brains don’t have enough dimensions.” Cheng Xin thought back to the conversation with the Ring again. Did you build this four-dimensional fragment? You told me that you came from the sea. Did you build the sea? “You are saying that the universe of the Edenic Age was four-dimensional, and that the speed of light was much higher?” “No, not at all. The universe of the Edenic Age was ten-dimensional. The speed of light back then wasn’t only much higher — rather, it was close to infinity. Light back then was capable of action at a distance, and could go from one end of the cosmos to the other within a Planck time.… If you had been to four-dimensional space, you would have some vague hint of how beautiful that ten-dimensional Garden must have been.” “You’re saying — ” “I’m not saying anything.” Yifan seemed to have awakened from a dream. “We’ve only seen small hints; everything else is just guessing. You should treat it as a guess, just a dar

Everything was deathly quiet. The eyes were the most terrifying: the eyes of dinosaurus; the eyes of trilobites and ants; the eyes of birds and butterflies; the eyes of bacteria... The humans alone possessed one hundred billion pairs of eyes, equal to the number of stars in the Milky Way, Among them were the eyes of ordinary men and women, and the eyes of Da Vinci, Shakespeare, and Einstein.

The universal laws of physics are the most terrifying weapons, and also the most effective defenses.

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.

Even Coca-Cola probably tasted medicinal the first time you tried it. Anything addictive is like that.

This was the theory of “contact as symbol” proposed by sociologist Bill Mathers of RAND Corporation in his book, The 100,000-Light-Year Iron Curtain: SETI Sociology. Mathers believed that contact with an alien civilization is only a symbol or a switch. Regardless of the content of the encounter, the results would be the same.

Every day on this planet some species that doesn't draw the attention of humans goes extinct.

Mom, I'm going to be a firefly.

Perhaps the outside world really was something akin to a quantum state, and did not exist unless he observed it.

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.

Afterwards, the princeps asked the science consul, “Did we destroy a civilization in the microcosmos in this experiment?” “It was at least an intelligent body. Also, Princeps, we destroyed the entire microcosmos. That miniature universe is immense in higher dimensions, and it probably contained more than one intelligence or civilization that never had a chance to express themselves in macro space. Of course, in higher dimensional space at such micro scales, the form that intelligence or civilization may take is beyond our imagination. They’re something else entirely. And such destruction has probably occurred many times before.” “Oh?” “In the long history of scientific progress, how many protons have been smashed apart in accelerators by physicists? How many neutrons and electrons? Probably no fewer than a hundred million. Every collision was probably the end of the civilizations and intelligences in a microcosmos.

The past was like a handful of sand you thought you were squeezing tightly, but which had already run out through the cracks between your fingers. Memory was a river that had run dry long ago, leaving only scattered gravel in a lifeless riverbed.

Pan-Species Communism. It’s an ideology I invented. Or maybe you can call it a faith. Its core belief is that all species on Earth are created equal.
