Is the description of the wandering earth pushing the earth out of the solar system feasible in reality?

The Wandering Earth series movies have been released, which is the first time that the works of science fiction writer Liu have been put on the screen. In fact, a great feature of Liu's works is loyalty to science, and most of the scientific and technological things involved are supported by scientific theories and are logical. As far as the work of wandering the earth is concerned, although it can't be done with the current technology, the assumptions in his work can basically be done with the future technology.

The premise of the wandering earth story is that the sun will flash helium, but in fact, it will take 3-5 billion years for this event to happen. In the flash of helium, the sun will instantly release the nuclear fusion energy equivalent to millions of years. This kind of energy explosion is unbearable for the earth, which will evaporate all the oceans of the earth in an instant and burn the ground into lava, not to mention the ecological environment and life species on the surface of the earth. So once it is determined that the sun will flash helium, then human beings must act in advance.

In the work of wandering the earth, scientists predicted hundreds of years in advance that the sun would flicker with helium and later become a red giant, which also represented the coming end of mankind. If we want to avoid extinction, we must stay away from the sun. How to stay away from the sun? Scientists believe that this may be the best way to leave the whole earth. It takes a long time and enough energy and resources for human beings to cross the endless interstellar space to find other star systems. However, if it is time-consuming and laborious to build a spaceship, and I am afraid that energy resources and the space of the spaceship are insufficient, so human beings decide to control the whole earth and leave the solar system.

The earth is a big guy with a mass of 59.6 trillion tons. Driving the whole earth out of the solar system undoubtedly requires a huge thrust and a stable posture to push it forward. Therefore, scientists have created huge engines, each of which is as high as 10000 meters, and built more than 10000 engines in the relatively stable part of the earth's crust. They first braked the earth's rotation, and it took more than 40 years to make it turn.

It is also assumed that human beings have mastered the heavy element nuclear fusion technology, so that the rock resources on the earth can be used as fuel and can drive huge earth engines, and each engine can generate/kloc-0.5 billion tons of thrust. In fact, this kind of engine should be no problem, and it may not cause the earth's crust to bear such a huge level of its own weight and its thrust, because in fact the earth's crust is very thin. Compared with an egg, the earth's crust is not as thick as an eggshell, so it is so huge.

Another point here is that although the engine is as high as 65438+100000 meters, the air in the earth's atmosphere is1000 kilometers thick, so when the engine drives the plasma beam, it will also blow the earth's atmosphere out of the atmosphere, which will cause the air on the earth's surface to become thinner and thinner, and the air pressure will become lower and lower. Fortunately, at this time, human beings have moved underground to survive and entered a closed environment, so they are not too worried about the changes in the atmosphere on the surface of the earth.

If the earth wants to leave the solar system, it needs to be accelerated by the gravitational slingshot effect of the sun and Jupiter, which is also very realistic. Compared with the earth, the sun and Jupiter are both celestial bodies with great gravity, and the gravitational slingshot effect can accelerate the speed of the earth, especially Jupiter. Because it is far enough away from the sun and its mass is hundreds of times larger than that of the earth, slingshot effect can get the speed of leaving the solar system by relying on Jupiter's gravity, so this link is highlighted in the film. Finally, human beings let the earth get it through the acceleration of Jupiter.

Proxima centauri is a red dwarf star, its own mass is relatively small, helium flash will not occur, and its life span is very long, reaching nearly 100 times that of the sun, but its livable zone is relatively narrow, and the earth needs more than 7 million kilometers away from proxima centauri to restore our current ecological environment. Moreover, scientists have found that there is a planet with a mass greater than that of the Earth in this livable zone of proxima centauri. If the Earth gets there, it will be like a planet.

One more thing, according to the observation, the activities of the stars in proxima centauri are not very stable, and the plasma wind is often longer than the stellar wind from the sun, which is not conducive to the existence of the earth's ecological environment. And it's hard to say whether there will be a magnetic field when the earth wanders without the moon, but when Liu wrote The Wandering Earth, human observation of proxima centauri was not as detailed as it is today, so it didn't hinder a great work.

In short, if human beings really have the technological level of wandering earth and really predict the phenomenon of sun and helium flash hundreds of years later, it is also desirable to adopt the method of wandering earth immigration to save themselves.
