We are all vagrants, wandering in the world with loneliness and fear.

Stephen Hawking, a famous physicist, once predicted that the earth would be destroyed in two hundred years.

He predicted the destruction of the earth in two ways:

First, he was destroyed by alien invasion.

second, it was destroyed by the sun.

Hawking thinks that the latter is more likely, so he has always advocated finding livable planets outside the earth to ensure that human beings can be prepared before disasters.

As early as 215, scientists discovered that the sun would go into hibernation in 23, the earth would go into the Little Ice Age, and after the sun went into hibernation, human beings would be extinct.

Many scientists believe that interstellar migration is the only way out for human beings, and many sci-fi movies and stories also use this as a reference to set up plots and plots with wide brain holes.

However, Liu Cixin's science fiction The Wandering Earth is completely different from this kind of interstellar migration. It tells a story: Astrophysicists predict that the solar helium flash will occur in 2 years according to an accurate mathematical model, and the solar helium flash will lead to the destruction of the earth. Therefore, human beings plan to immigrate to proxima centauri Centauri.

due to the limited technology-the spacecraft that human beings can make with the current technology can't stand the wind and waves of time compared with the earth's ecosystem, so human beings finally gave up the idea of making a spaceship and decided to turn the earth itself into a spaceship and escape from the solar system by driving it.

This interstellar migration didn't move to any planet, but fled and wandered with the earth, so the novel was named The Wandering Earth.

The Wandering Earth is a short story written by Liu Cixin, the "first man of contemporary science fiction in China" in 2. At that time, he was a computer engineer in Niangziguan Power Plant in Yangquan City, Shanxi Province. He was fond of science fiction and often used his spare time to write novels.

It is said that this The Wandering Earth only took more than a week before and after, and Liu Cixin won the special prize of China Science Fiction Galaxy Award for it.

after a lapse of five years, he wrote the classic novel Three-body, which won the Hugo Award, the highest award in the world science fiction circle.

In The Wandering Earth, we can vaguely see the embryonic form or shadow of the novel Three-body, and some science fiction critics even think that The Wandering Earth is more wonderful than Three-body.

The Wandering Earth, a sci-fi film of the same name based on the novel, was released in China on February 5th this year. It is the first large-scale sci-fi film in China. As of 12: 29 on the 17th, the movie The Wandering Earth accumulated 3.651 billion yuan at the box office, surpassing Operation Red Sea (3.648 billion yuan) and became the runner-up in the movie box office in mainland China.

If you don't have time to read the whole Three-body, please be sure to read this short story The Wandering Earth.

The novel takes place in such a background: more than three centuries ago, astrophysicists established a complete and accurate mathematical model of the sun. The calculation results of this model by a supercomputer show that the sun will produce a violent explosion called helium flash, which will take place in a short time. After that, the sun will become a huge but dim red giant, which means that the earth will vaporize in the helium flash explosion, and all this will happen within 4 years.

in order to avoid the helium flash from the sun, human beings decided to turn the earth itself into a spaceship by installing an earth engine to change the orbit and speed of the earth, and by driving the earth to escape from the solar system, they immigrated to the nearest proxima centauri.

The novel divides human flight into five steps:

The first step is to stop the rotation of the earth with the earth engine, so that the engine nozzle is fixed in the opposite direction of the earth's operation;

step 2, start the earth engine at full power to accelerate the earth to escape speed and fly out of the solar system;

Step 3, continue to accelerate in outer space and fly to proxima centauri;

step four, make the earth rotate again in the middle, turn the direction of the engine and start to slow down;

Step 5, the Earth will be put into proxima centauri orbit and become a satellite of this star.

people call these five steps: braking age, escape age, wandering age I (acceleration), wandering age II (deceleration) and new sun age.

The whole immigration process will last for 2,5 years, with a hundred generations.

As the protagonist, "I" was born in the braking era, so I witnessed the immigration process from the braking era to the wandering era for half a century.

The sun, a symbol of human spirit that has long symbolized hopes and dreams, has now become synonymous with fear. People are afraid of the sun.

Death is no longer black, but discerning. "It is the color of lightning. When the last lightning comes, the world will turn into steam in an instant."

After the earth's orbit changes and accelerates, the escape era comes. Every time the earth reaches perihelion, people's fears increase sharply, and there are rumors in society. People are worried that helium flash will be vaporized in an instant before it can escape from the solar system. When the earth rises to the apohelion, people's fears gradually subside.

School education began to focus on science and engineering, and the education of art and philosophy was reduced to a minimum, and religions on the earth disappeared overnight.

when the threat of death and the desire to escape overwhelm everything, everything becomes irrelevant except the state of the sun and the position of the earth. Things that we don't usually care about often become valuable, while things that are regarded as treasures become insignificant.

Hope is a treasure

Every time the earth falls to the perihelion, there will be rumors everywhere. My mother also doubts whether it is really too late to escape from the solar system, helium flash will happen and the earth will be destroyed. At this time, my father, who is a soldier, said very firmly:

"Listen, dear, we must have hope, not because hope really exists, but because we want to be noble people. In the pre-sun era, to be a noble person must have money, power and talent, but today as long as we have hope, hope is the gold and gem of this era, no matter how long we live, we must have it! Tell this to the child tomorrow. "

In the real world, a person only needs money, power or talent to walk freely in this world, which is also the standard to measure a person's success in our real world. However, in an era full of despair, these things are not so important.

Hope has become so important that if you want to live in despair, you must have hope for the world and the future, even if hope doesn't really exist.

ethical standards have changed

when the earth rises to the apohelion, once my family went to the seaside for a trip, my father suddenly told me and my mother that he fell in love with my primary school teacher and wanted to leave them and find her.

When my mother learned about it, she didn't respond. In the face of her father's infidelity, she just said, "Then you go."

My father went on to say that he would get tired of her after a while, and he would come back when the time came. My mother said, "Sure, if you want." Then, her attention was attracted by the stars on the horizon, as if nothing had happened.

when the underground city suffered a magma explosion, the government announced to evacuate the underground city according to Article 5 of the Emergency Law. The fifth article of the emergency law is to queue up for evacuation according to age, and the youngest is the first to evacuate.

Ethics in Liu's novels can be flexibly adjusted according to situations and conditions, which is reflected in both The Wandering Earth's novel and Three-body novel.

As Liu said, we think that ethics is a fixed thing at present, which is actually a misunderstanding. It will certainly change with the development of technology and civilization and adapt to the new environment.

Loneliness is no different from death

In the novel, when the earth reaches the apohelion for 12 times, in order to alleviate people's nervousness, the coalition government resumed the Olympic Games that had been interrupted for two centuries, and "I" participated in the motor sledding rally. The race started from Shanghai, crossed the frozen Pacific ice and reached the destination of new york.

When the competition started, I gradually distanced myself from my companions. When my companions disappeared out of the horizon one by one, the author described my feelings like this:

"I am the only one in the universe composed of infinite starry sky and infinite ice sheets! Avalanche loneliness overwhelmed me, and I wanted to cry. I hurried on desperately, and the ranking was irrelevant, just to get rid of this terrible loneliness as soon as possible before it killed me ... "

I would rather not be ranked than be abandoned alone in an empty ice field.

we are afraid of loneliness as we are afraid of death.

I would rather gather in the crowd, warm each other and comfort each other, so as to gain hope and strength than fight alone.

death is terrible, but we are more afraid of wandering at the end of the world alone.

The novel creates a magnificent and wonderful spaceship on the earth, and the details are full of rich and superb imagination. The final reversal is quite ironic, showing the essence of human nature to the fullest.

In this era, no one is a wanderer who wanders around the world with loneliness and fear.

We leave our hometown and wander around, looking for hope, dreams, a new world and a new home. However, there is always an "earth" in every wanderer's heart, which is the attachment and memory of "home". We walk, wander and wander with it, and this has never changed.

Although the doomsday scene described in the novel will not happen in the real world, the insecurity of reality and the uncertainty of the unknown are the feelings that each of us once had.

Fear of failure, anxiety for survival, avalanche loneliness, illusory sense of security, and constant wandering between hope and despair are our lives, but from Liu Cixin's novels, we can still read hope.

fortunately, we are still alive.
