History of interstellar migration of human scientists

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

He predicted the destruction of the earth in two ways:

First, it was destroyed by alien invasion.

Second, destroyed by the sun.

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

As early as 20 15, scientists discovered that in 2030, the sun would go into "dormancy", the earth would go into "Little Ice Age", and after the sun went into dormancy, human beings would become extinct.

Many scientists believe that interstellar migration is the only way out for human beings, and many science fiction films and stories also use it as a reference to set up plots and plots with big brain holes.

However, Liu's science fiction novel The Wandering Earth is completely different from this kind of interstellar migration. It tells a story: according to an accurate mathematical model, astrophysicists predict that solar helium flash will occur in 20 years, which will lead to the destruction of the earth. Therefore, human beings plan to immigrate to proxima centauri Centauri.

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

Interstellar immigrants did not migrate to any planet, but fled with the earth and wandered with the earth, so the novel was named Wandering Earth.

The Wandering Earth is a short story published in 2000 by Liu, the "first man of contemporary science fiction in China". At that time, he was a computer engineer at Niangziguan Power Plant in Yangquan City, Shanxi Province. He likes science fiction and often writes novels in his spare time.

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

After a lapse of five years, he created the classic novel "Three-body" and won the Hugo Award, the highest prize 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 even some science fiction critics think that The Wandering Earth is more wonderful than Three-body.

The Wandering Earth, a sci-fi film of the same name based on this novel, was released in China on February 5th this year. It is the first large-scale sci-fi movie in China. By the end of 17, 12: 29, the cumulative box office in The Wandering Earth reached 365 1 100 million yuan, surpassing Operation Red Sea (3.648 billion yuan) and becoming the runner-up in the mainland movie box office.

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 this background: more than three centuries ago, astrophysicists established a complete and accurate mathematical model of the sun. The calculation results of this model by supercomputer show that the sun will produce a violent explosion called helium flash, which will happen in a short time. After that, the sun will become a huge but dim red giant, which means that the earth will evaporate in the helium flash explosion, and all this will happen within 400 years. It's been 380 years now.

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

The novel divides human escape into five steps:

Step 1, stop the earth's rotation with the earth engine and fix the engine nozzle in the opposite direction of the earth's operation;

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

The third step is to continue to accelerate in outer space and fly to proxima centauri;

Step 4, let the earth rotate again in the middle, turn the direction of the engine and start to slow down;

Fifth, the Earth will be anchored in proxima centauri orbit and become a satellite of this star.

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

The whole immigration process will last for 2500 years, 100 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, has long symbolized hopes and dreams, and now it has become synonymous with fear. People are afraid of the sun.

Death is no longer dark, but knows right from wrong. "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 change accelerated, the era of escape came. Whenever the earth reaches perihelion, people's fears are high and rumors are everywhere in society. People are worried that helium flash will evaporate in an instant before it can escape from the solar system. When the earth rises to the apohelion, people's fears gradually fade away.

School education began to focus on science and engineering, education in art and philosophy was minimized, 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. What we don't usually care about often becomes valuable, while what is regarded as a treasure becomes insignificant.

Hope is a fortune.

Whenever the earth falls to perihelion, there will be rumors, and my mother is also wondering if it is really too late to escape from the solar system. Helium flash will happen and the earth will be destroyed. At this time, as a soldier's father, he said very firmly:

"Listen, my 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, you must be rich, powerful and talented. 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 children tomorrow. "

In the real world, a person only needs to be rich, powerful or talented to walk unimpeded in this world. This 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.

Ethics and moral standards have changed.

When the earth rose to the distant sun point, once, our family went to the seaside to travel, and my father suddenly told me and my mother that he fell in love with my primary school teacher and wanted to leave me to find her.

Mother didn't react when she learned about it. In the face of her father's infidelity, she only said, "Then go."

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

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

The ethics in Liu's novels can be adapted to the times, which is reflected in The Wandering Earth and Three-body.

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

There is no difference between loneliness and death.

In the novel, when the earth reached apohelion 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" took part in the motor sled rally. The race started from Shanghai, crossed the frozen Pacific ice and reached the destination of new york.

At the beginning of the game, "I" gradually distanced myself from my companions. When my companions disappeared from the horizon one by one, the author described my feelings like this:

"In the infinite starry sky and infinite ice sheet, I am the only one! The avalanche of loneliness overwhelmed me, and I wanted to cry. I was desperately on my way, and the ranking didn't matter, 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 on an uninhabited ice sheet.

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

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

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

The novel created a magnificent and wonderful spaceship on the earth, and the details were full of rich and superb imagination. The final reversal is quite ironic, showing the essence of human nature incisively and vividly.

In this era, who is not a wanderer wandering in this world with loneliness and fear.

We leave our hometown and wander around, looking for hope, dreams, new worlds and new homes. However, in every wanderer's heart, there is always a "soil", which is the attachment and memory of "home". We walk with it, wander, wander, and never change.

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

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

Fortunately, we are still alive.
