In the movie, why did humans choose to run with the earth?

At the end of the movie, Jason Wu plays Lieutenant Colonel Liu Peiqiang, who drives a spaceship into an ion beam to detonate Jupiter's wandering earth scene, which touches many people.

However, the background of the previous story has been introduced. Liu Peiqiang's space station and Voyager contain priceless treasures such as the earth's species gene bank, plant seeds and civilization data. Is it really worth saving the collapsing earth with these "last fires of civilization"?

In fact, in addition to the gene pool and data, the most important thing for navigators is actually a group of astronauts who are strictly selected around the world. I wonder if you can notice the details in the movie. The navigator space station is clean and efficient, and astronauts from different countries cooperate with each other in harmony and work in an orderly manner.

On the other hand, looking back at the underground city on the earth, the messy living environment, the complex of bourgeois kings and the poor and weak living conditions, we can boldly speculate that the earth in the film has actually been artificially extinct from the beginning of the expedition plan.

From the perspective of the whole earth and geological age, it doesn't matter what human beings do, and they will be forgotten with the disappearance of the earth-except one thing: space navigation.

All the achievements and all the destruction will be meaningless in billions of years, but flying out of the solar system on a large scale may last until the end of the universe or even longer. Moreover, this seems to be a feat that only intelligent life can achieve. If human beings are of any value to the earth, it is probably this one.

Taking the whole earth away may be the pinnacle of space navigation. ...

Therefore, in Liu's novel The Wandering Earth, when the earth civilization is facing extinction because of the helium flash of the sun, human beings are not only determined to abandon the sun completely, but also hang up a powerful engine for the earth to push it to travel together until it reaches the south gate (Alpha Centauri) four light years later, and everything starts all over again.
