These are the notes and excerpts I recorded while reading "The Complete Trilogy of The Three-Body Problem" on WeChat Reading.


17 The Three-Body Problem#

I am inherently indifferent to women, even less interested than the monks around me, but she is special; her most un-feminine femininity attracted me.

34 Sophon#

When these two protons are separated from the nucleus, no matter how far apart they are, this rule still holds; changing the spin direction of one proton will immediately cause the other to change its spin direction correspondingly.

35 Bugs#

All the atoms in this universe will eventually unfold into lower dimensions over a long period of time; the ultimate fate of our universe is to become a macrocosm composed of low-dimensional atoms, which can also be seen as a process of entropy increase.

Postscript#

The city is a forest; every man is a hunter, and every woman is a trap.

Year 3 of the Crisis Era The Three-Body Fleet is 4.21 Light-Years from the Solar System (1)#

If your cunning is deep enough, then you cannot show any cunning.

Most people's objects of love only exist in their imagination. They do not love the real her (him), but only the imagined her (him); the real her (him) is merely a template for the dream lover they create. They will eventually discover the difference between the dream lover and the template; if they adapt to this difference, they will come together; if they cannot adapt, they will part ways. It's that simple. The difference between you and most people is: you do not need a template.

I am becoming death, the destroyer of worlds.

This is a quote from Oppenheimer when he saw the first nuclear bomb explode, seemingly referencing the Indian epic "Bhagavad Gita."

Year 8 of the Crisis Era The Three-Body Fleet is 4.20 Light-Years from the Solar System#

Wallfacer Luo Ji, I am your wallbreaker.

Year 205 of the Crisis Era The Three-Body Fleet is 2.10 Light-Years from the Solar System (1)#

Give civilization to time, not time to civilization.

That famous saying from the revolution is actually a paraphrase of Pascal: Give life to time, not time to life.

Men always remember love because of romance only[illustration].

"Oh... no, I generally do not disturb the girls I love; I believe in Goethe's saying: I love you, what does it have to do with you?"

Over two centuries ago, Arthur C. Clarke described a black monolith left by an alien super civilization on the Moon in his science fiction novel "2001: A Space Odyssey." The observer measured the three edges of the monolith with a regular ruler, and their length ratio was 1:3:9. Later, no matter how precisely it was measured, exhausting the highest precision of measurement technology on Earth, the ratio of the three edges of the monolith remained precisely 1:3:9, with no error. Clarke wrote: That civilization arrogantly displayed its power in this way.

To destroy you, what does it have to do with you?

The universe is a dark forest; every civilization is a gun-wielding hunter, stealthily moving through the woods, gently pushing aside the branches in their way, striving to make no sound with their footsteps, even their breathing is cautious... They must be careful because there are hunters lurking in the forest just like them. If they discover other life, regardless of whether it is a hunter, an angel, or a devil, regardless of whether it is a delicate baby or a stumbling old man, regardless of whether it is a fairy-like girl or a god-like boy, the only thing they can do is to shoot and eliminate it. In this forest, others are hell, an eternal threat; any life that exposes its existence will soon be eliminated. This is the picture of cosmic civilization; this is the explanation for the Fermi paradox.

Year 208 of the Crisis Era The Three-Body Fleet is 2.07 Light-Years from the Solar System#

If I have done something wrong, please forgive me.

Year 61 of the Deterrence Era The Swordbearer#

As time passed, Luo Ji's image transformed from a savior into an incomprehensible monster and a tyrant who destroys the world.

Year 1 After Deterrence Australia#

All tribes have disappeared, and all spears have been broken. Here, we once drank dew and ate flowers, while you scattered a field of gravel.

Year 7 of the Broadcasting Era Yun Tianming's Fairy Tale#

The soap dissolves in water, reducing the surface tension of the water behind the small boat, but the surface tension of the water in front remains unchanged, so the small boat is pulled forward by the surface tension of the water in front[illustration].

Death is the only lighthouse that is always lit; no matter where you sail, you must eventually turn towards the direction it points. Everything will pass away; only death is eternal.

People call low-speed black holes "black domains" because, compared to regular-speed black holes, the Schwarzschild radius of low-speed black holes is very large, and the interior is not a spacetime singularity but a vast area.

Year 11 of the Shelter Era The Shelter World#

The sun has set; mountains, trees, stones, rivers, all great buildings are buried in shadows; humans amusingly light their little lamps: rejoicing in what they see; hoping to find what they seek.

Year 67 of the Shelter Era Orion Arm of the Milky Way#

I saw my love; I flew to her side; I presented her with a gift, a small piece of solidified time, with beautiful stripes on it, soft like the mud of a shallow sea...

The entropy of the universe is rising, order is decreasing, like the boundless black wings of a balancing roc pressing down on everything that exists. But low-entropy bodies are different; the entropy of low-entropy bodies is still decreasing, and order is still increasing, like the phosphorescence rising on a dark sea; this is meaning, the highest level of meaning, higher than the meaning of pleasure. To maintain this meaning, low-entropy bodies must exist and continue.

The time has beautiful stripes, soft like the mud of a shallow sea; she covered herself with time and then pulled me to fly towards the edge of existence; this is a spiritual flight; the stars in our eyes look like ghost stars, and we in the eyes of the stars also look like ghosts...

Year 66 of the Shelter Era The Outer Solar System#

If the mountain does not go to Muhammad, Muhammad can go to the mountain.

Wahahaha... there is no banquet that has not been disturbed, no virgin that has not been touched, wahahaha...

I say do not be arrogant; weakness and ignorance are not obstacles to survival; arrogance is. Think of the water droplet!

Year 67 of the Shelter Era Pluto#

The voice comes from the end of the ramp, where an old man stands; in the dim light, his long white hair and beard float in low gravity, as if glowing. "Are you Luo Ji?" AA asked loudly.

Civilization is like a five-thousand-year mad dash, with constant progress driving faster progress, countless miracles giving birth to greater miracles, and humanity seemingly possessing god-like power... But in the end, it is discovered that true power lies in time; leaving footprints is harder than creating worlds. At the end of this civilization, they can only do what ancient infants once did.

Year 67 of the Shelter Era Two-Dimensional Solar System#

Four centuries ago, at the peak of the Red Coast Base, Ye Wenjie saw such a sunset in the last moments of her life. At that time, her heart was beating laboriously, like a string about to break. Black mist began to appear before her eyes; the setting sun sinking into the sea of clouds in the western sky seemed to melt, the blood of the sun spreading in the sea of clouds and space, reflecting a vast expanse of magnificent crimson. She said this was humanity's sunset.

Luo Ji raised his cane to bid farewell to them, then turned and walked towards the monolith. In low gravity, he floated like walking on snow, occasionally tapping the ground with his cane to slow down. Cheng Xin and AA watched him until the aging figure of this wallfacer, swordbearer, and humanity's last gravekeeper disappeared into the door of the monolith.

About 17 Billion Years After Time Our Stars#

We have lived a happy life; we send you a small one to hide from the collapse to new.

Beyond Time Our Universe#

Cheng Xin began to write her memoirs, recording the history she knew; she called it "The Past Beyond Time."
