Who did three-body gravity meet?

Have a general understanding of her life in the novel. Before you start combing, please explain some important concepts:

1, three-body civilization: an alien civilization living in Samsung Centauri (the closest star system to the solar system), the civilization development degree is much higher than that of the earth civilization.

2. Naoko: Three-body civilization unfolded protons in two-dimensional space, and etched circuits on it, transforming it into a supercomputer "Naoko". Naoko sent to the earth can monitor everything on the earth in real time, and at the same time, the physical characteristics of microscopic particles of Naoko can hinder the basic scientific development of earth civilization.

3.Step plan: PIA (Strategic Service Office of the Planetary Defense Council) plans to send probes to the trimaran fleet, so it is named Step plan because its acceleration mode is like climbing a step.

4. Fairy tales of clouds: Clouds exposed to the three-body civilization have carefully compiled a series of fairy tales in the three-body first fleet, hiding information about the earth civilization in three of them.

1. Crisis era: 20 1X year -2208 (the chronological comparison table is taken from three body 3: Death and Eternal Life).

The first year of the crisis era: Cheng Xin joined PIA, participated in the ladder plan, and studied the feasibility scheme for this purpose.

Crisis era 3: PIA decided to send only one person's brain, and the ladder plan was fully launched and began to look for suitable candidates.

Four years in the crisis era:

Yun Tian Ming gave Cheng Xin a star (DX3906).

-Yun Tian Ming, who is terminally ill, decided to euthanize. Cheng Xin found Yun, and Yun decided to join the ladder project.

Five-year crisis era: Yun was elected as the task executor of the ladder plan.

5-7 years of crisis:

-the earth began to build space elevators.

Yun Tian Ming's brain was launched into space in an aircraft.

Cheng Xin is hibernating.

Second, the era of deterrence: 2208-2270.

Deterrence era 6 1 year:

-DX3906 star held by Cheng Xin was discovered by doctoral student Ai AA with two planets. So Cheng Xin was awakened from hibernation, and the United Nations demanded to buy back the ownership of DX3906 star from Cheng Xin. Cheng Xin transferred the right to use the two planets carried by DX3906 to the United Nations.

-Cheng Xin gave Ai AA the money to sell the planet, and Ai AA set up Star Ring Company.

-Thomas Vader, the first director of PIA, was sentenced to 30 years in prison for attempting to assassinate Cheng Xin.

-Cheng Xin decided to run for "Sword Holder".

Deterrence era 62: Cheng Xin was elected as the second "sword bearer". At the moment when the new and old swordsmen handed over, the dark forest failed to play a deterrent role.

Third, after deterrence: AD 2270-AD 2272

The first year after deterrence: Naoko announced that Australia and one-third of Mars on the earth would be the residence reservation of the earth civilization, and human beings needed to complete the immigration action within one year. Cheng Xin and Ai AA followed the first batch of immigrants to Australia.

Two years after deterrence:

-Three days before the deadline, the great migration was completed.

-Cheng Xin suffered a super strong mental shock, which led to retinal detachment, necrosis and blindness. At the same time, she also fell into mild depression.

-The three-body world knows that gravity has begun to broadcast gravitational waves and thinks that the solar system is no longer safe. The three-body civilization controlled the three-body fleet to turn away from the solar system, and the water droplets also left the earth. Earth civilization began with the evacuation of Australia.

Fourth, the broadcasting era: AD 2272- AD 2332.

The first year of broadcasting era:

-Cheng Xin set off for the motherland and began to hibernate briefly, waiting for the retina that can treat the eyes to be made.

-Evacuation complete.

Seven years in the broadcasting era:

-Cheng Xin woke up from a short hibernation, completed a retinal transplant and recovered his vision.

-Earth civilization observed the destruction of the three-body world, which once again verified the existence of the dark forest law.

-Naoko robot invited Cheng Xin and Luo Ji to have tea, and bid farewell to mankind, and told all Naoko that they would leave the earth, and informed Cheng Xinyun that Tian Ming wanted to see her.

Cheng Xin met Yun and learned about three fairy tales written by Yun for the earth civilization. Yunhe agreed to meet in DX3906 star system in the future.

-Set up the Intelligence Interpretation Committee (IDC) to begin to interpret cloud fairy tales.

Eight years in the broadcasting era:

Based on the information brought by cloud fairy tales, the earth civilization foresees three ways to deal with the attack of dark forests: bunker plan, black domain plan and light speed spacecraft plan.

Ringo-Fizro Observatory observed the traces left by the curvature-driven spacecraft (light-speed spacecraft) of the three-body civilization, which led Fleet International and the United Nations to quickly and completely ban the research on curvature-driven spacecraft.

-Cheng Xin handed the ring company to Vader, but reserved the right to decide on major events. Vader began the secret research and development of the light speed spacecraft.

-Cheng Xin and AA go into hibernation.

5. The bunker era: 2333-2400.

Bunker era 1 1 year:

-Cheng Xin woke up from hibernation and was taken to the ring road, where Vader's resistance to the federal government was stopped.

-Thomas Vader was sentenced to death for crimes against humanity, war crimes and violation of laws prohibiting curvature-driven technology.

-The research on the drive technology of ring suite rate is stagnant.

-aa woke up from his winter sleep and returned to the earth with Cheng Xin.

-Cheng Xin and Ai AA hibernate in Asia No.1 Space City again, ready to wake up after the dark forest strikes.

Bunker Age 46: Research on the Restoration of Mercury Base Based on Space Curvature Driving Technology.

Bunker era 63: Three sets of curvature engines were secretly manufactured and two tests were carried out. The first test engine 1 will return in three years, and the second test engines 2 and 3 are expected to return in ten years.

Bunker era 66: The first curvature engine returned from the first test was installed on the "star ring".

Bunker era in 67 years:

-Cheng Xin and Ai AA woke up from hibernation and came to the Earth Civilization Museum in Pluto with the "Star Ring", learning that the "Star Ring" can fly at the speed of light.

-Cheng Xin and Ai Yi take the light speed spacecraft "Star Ring" to DX3906.
