"Wandering Earth 2" is finalized! If I don't worry about spoilers, I'll talk about the plot in advance.

If there is only one in The Wandering Earth, it's really not enough to watch. Although the first one is wonderful enough, it only shows a glimpse of the original novel.

Summary of this issue:

1. Half a cat really can't help it, so it is necessary to supplement the world outlook setting that didn't say "complete" in the first part.

2. I really can't help it. I have to predict the story of Wandering Earth 2 in advance.

1. Why did the Earth leave the solar system to wander

This important background is also mentioned in Wandering Earth 1. Our sun is sick and terminally ill.

But the movie seems to be worried that the audience can't digest the scientific truth in the original, so it explains this background knowledge in the most understandable language-the sun is aging rapidly and expanding continuously. After one hundred years, the sun will expand to engulf the whole earth, and after three hundred years, the solar system will no longer exist.

then, if we use more scientific language, how should we explain it?

the theoretical life span of the sun is about 1 billion years, and at present the sun is about 4.57 billion years old.

from the chemical composition, about three-quarters of the mass of the sun is hydrogen, and the rest is almost helium, including oxygen, carbon, neon, iron and other heavy elements, with the mass less than 2%. Every day, the sun uses nuclear fusion to burn hydrogen atoms to produce helium, releasing light and heat into space.

However, as the burning area gradually moves outward, the middle becomes a helium nucleus. When the volume of the helium nucleus increases, the temperature and density of the inner center will increase. At this time, the helium nucleus is suddenly ignited, which is more intense than burning the hydrogen nucleus: the energy generated in four minutes is equivalent to the energy generated by the sun in two million years today. This process is called helium flash.

There is no mention of the concept of "helium flash" in the movie, but it is a well-known nightmare in the novel. It can be said that the whole novel revolves around people's fear of helium flash.

Originally, this process was several billion years away from us, but the wandering earth secretly modified the parameters.

As a result, the speed of converting hydrogen into helium in the sun suddenly increases, and the evolution of the sun will shift out of the main sequence, and the fusion of helium will spread throughout the sun in a short time, resulting in "helium flash".

After that, the sun will become a huge but dim red giant. It will expand so much that the earth will run inside the sun! In fact, in the helium flash explosion before this, our planet has been vaporized.

That's how teachers in schools teach primary school students.

In this way, human beings can no longer survive in the solar system, and the only way to survive is to emigrate to the outer space stars.

According to the current technological strength of human beings, the only feasible target for all human immigrants is proxima centauri Centauri, which is the nearest star. But even recently, it was 4.3 light-years away, and it took more than four years to fly.

2. Earth School vs Spacecraft School

All mankind has reached a consensus on whether or not to emigrate from the stars, but there are serious differences on the way of emigration.

So there are the Earth School and the Spacecraft School.

It's true that Centauri has the nearest star, but Centauri has no planets, only three stars.

The nearest star with planets is 85 light years away. According to the level of human science and technology in the novel, the fastest spaceship that can be built can only reach .5% of the speed of light, which means it will take 17, years to get there.

It is impossible for an ordinary spaceship to have an ecosystem for such a long time. A human spaceship will be swallowed up by the universe like a boat without a harbor.

so there is the "earth school".

the earth faction advocates installing a planetary engine on the earth, pushing it out of the solar system and taking it to the distant Centauri.

But some people think that there is not much time left for mankind. Humans will be swallowed up by the sun before they can push the earth out of the solar system. You know, it's not easy to get the earth out of the revolution of the sun. It's not as simple as resisting the centrifugal force of the hula hoop.

The height of the planetary engine should reach 11, meters, and the highest mountain on earth, Mount Everest, is only 8,848 meters. The main diameter of the engine is 2-3 kilometers, and the base diameter is 5-6 kilometers. Such a behemoth is called "God's blowtorch", each of which generates 15 billion tons of thrust on the earth.

And this kind of "blowtorch" needs 12, to move the earth. Even if it is pushed, it will only slowly start to accelerate, and it will take a hundred years to get out of the danger zone of solar eruption.

Relatively speaking, it is definitely much easier to build a spaceship, and the human beings in the novel already have the ability to build a spaceship as big as Shanghai or new york.

so there is the "spaceship school".

In any age, there will be partisan struggles. The era of wandering the earth belongs to the Earth School and the Spacecraft School.

in the end, the ruling party belongs to the earth faction.

Man set out with the earth.

PS: In fact, although there is no clear distinction between "Earth School" and "Spaceship School" in the film, the betrayal of human beings by the International Space Station and its transformation into Noah's Ark can actually be understood as the clue of Spaceship School.

3. A complete plan for human beings to save themselves-Wandering Earth Plan

There are five steps for human beings to escape to save themselves:

In the first stage of braking, the planet engine is used to stop the rotation of the earth and make the engine nozzle aim at the opposite direction of the earth's operation;

In the second escape era, the planetary engine was started at full power, which accelerated the earth to escape speed and flew out of the solar system;

In the third stage of vagrancy I (acceleration), it continued to accelerate in outer space and flew to proxima centauri;

The fourth stage, Wandering Age II (deceleration), makes the earth rotate again in the middle, turns the direction of the engine and starts to decelerate;

in the fifth stage of the new solar age, the earth entered proxima centauri orbit and became the planet of this star.

The whole immigration process will last for 2,5 years, with 1 generations. These 1 generations will experience countless terrible disasters from the unknown universe.

This is the world outlook and values of "Wandering Earth", and our present era is called the pre-sun era by them. A colorful, incomparably beautiful and desirable era.

4. Completely different "feelings"

There is another biggest difference between our time and theirs. Unfortunately, this is not reflected in the film.

Therefore, people in the novel, even if they are married, can leave their spouses for a while and live with other members of the opposite sex just like a business trip, and their spouses will not feel any discomfort at all.

Half a cat thinks this is a very cool setting, but it may not be suitable in the movie, because without emotional factors, the drama of the movie will be greatly reduced. So it was not used in the movie, and I think it is understandable.

Since Wandering Earth started in July, the cast has only revealed that there are Jason Wu, Andy Lau, ZhangFeng yi and Wan Qian in the cast. In addition, there is little relevant information flowing out, and the tone is very tight. Of course, it is also possible that there is no music capital at all, just a concept. After all, it is hard to shoot Liu's works and find more breakthroughs on the original basis.

As for Wandering Earth 2, producer Gong Geer said a few words: It is still born out of Liu Cixin's novel The Wandering Earth of the same name. It tells the story of mankind looking for a new home in outer space. Compared with the previous film, the two key points of the film are continuity and innovation.

There is a very close relationship between the two films. Wandering Earth 2 will expand the world view of the last part, and strive to provide more imagination and freshness for the audience. In addition to Wandering Earth 2, there is also a certain plan for the development of IP in The Wandering Earth. "Whether the plan can really be realized depends on the quality of the film and the audience's acceptance."

Gong Geer seems to have said something, but he seems to have said nothing.

When we go to the official introduction of Wandering Earth 2, we can only find a few figures:

The sun is about to be destroyed, and mankind has built a huge propeller on the surface of the earth to find a new home. However, the road to the universe is full of dangers. In order to save the earth, young people wandering in earth times once again come forward and start a life-and-death battle against time ...

At first glance, this storyline just adds a "once again" on the basis of the first one.

In the original novel, the wandering journey of the earth in 25 years seems to be able to deal with the past with this impeccable universal description.

Half a cat dared to "predict" the story of Wandering Earth 2 with limited clues. Of course, it was not a random "prediction", but a well-founded "prediction".

several criteria must be met to make a prediction

Wandering Earth 2 Half Cat Edition

Main role

Liu Qi (the protagonist in the first part)

Liu Bixing (the son of Liu Qi)

Liu Qi's wife

Liu Qi's sworn brother-General Qin

(supporting roles are added as needed).

Jason Wu's Liu Peiqiang, Liu Qi's father, will mainly appear in the memory line.

And Liu Qi has grown into a professional soldier, a rank teacher.

The story happened in the wandering times, and the earth broke away from the orbit of the sun and began to accelerate towards Centauri.

The first act of the film begins with the infiltration of magma from the underground city of F112.

The residents of the underground city lined up in an orderly way, waiting for the evacuation. Traditionally, children have the right to a greater chance of survival, while adults must be behind them. This is the survival rule of human beings in the last days.

So 12-year-old Liu Bixing and his mother were forced to separate, and her mother stood at the back of the team. Liu Qi was not with their mother and son at that time, and was on a mission at the International Space Station.

When Liu Qi returned to the ground, he could never see his wife again.

The loss of his mother left an unforgettable scar in Liu Bixing's heart. At that time, his father was not around to protect his mother, which was the biggest gap between father and son. They gradually became the most familiar strangers.

When Liu Bixing grew up, he learned a secret that his father had been hiding. Because Liu Qi is a soldier, when the disaster comes, the family members of the soldiers can get the priority of being rescued. But obviously, the mother did not enjoy this right, and it was the result of Liu Qi's artificial reasons.

Liu Bixing and Liu Qi, who knew the truth, parted ways. In fact, Liu Qi and his son were rarely together because of their work.

Liu Bixing has always dreamed of becoming a pilot. His father Liu Qi tried his best to prevent him from becoming a pilot. In the days when his father is not around, Liu Bixing's favorite thing to do is to play simulated flying games in the black alley and earn pocket money with people pk. His skill is so good that everyone in the dark alley knows him.

At the age of 18, Liu Bixing secretly flew the fleet with someone else's ID.

but what he didn't know was that he was able to enter the flying fleet smoothly, not because he was clever, but because his father's sworn brother, General Qin, arranged it.

Liu Bixing's talent made him stand out quickly, saving his teammates in a dangerous flight and becoming a hero.

But it also exposes his true identity quickly. Be punished and expelled from the flying fleet.

The earth's space journey is full of dangers. This time, the earth will inevitably cross the asteroid belt and face the future of a narrow escape.

The only hope of mankind is to send a fleet to clear roadblocks with lasers and nuclear bombs. But the rocks in the asteroid belt are too big. Those rocks are as big as a mountain, and a 5-million-ton thermonuclear bomb can only make a small hole in it.

so the "spaceship faction" began to rally. They advocated that human beings must leave fire for their future, so they restarted the "fire plan" hidden in the snow for many years-driving a spaceship and leaving the earth with human elites and biological embryos.

And the leader of this plan is General Qin, Liu Qi's sworn brother.

At this time, the last card left for the earth faction is only the ultimate weapon of mankind-antimatter bomb.

The reason why the Earth School didn't use it at the beginning is that the antimatter bomb is extremely unstable. Once it is made, it will automatically explode in two days. If it leaves early, it will explode before it reaches the detonation area. If it leaves late, it will explode too close to the Earth, and the earth itself will be destroyed first. Therefore, the window during which tasks can be performed is very short.

If we want to completely solve the asteroid crisis, we must fly to the center of the asteroid belt with antimatter bombs. Asteroids are densely distributed and move irregularly, so it is almost impossible to complete this task.

another desperate thing is that even if the throwing is successful, the pilot will not have enough time to return, and will be smashed with the asteroid.

All the best pilots in active service volunteered to take part in this mission, willing to give themselves for the future of mankind.
