What do you think of the wandering earth, does it work scientifically?

"The Wandering Earth" is an excellent domestic science fiction film, since it was broadcast, many people have said this: "China finally has its own hardcore science fiction movie", this movie has not only achieved a bumper harvest at the box office, but also has a good reputation, and there is a trend comparable to Hollywood movies. <>

It can be said that "The Wandering Earth" is a science fiction short story**, which is very successful, and the imagination is very grand, bringing us science fiction with obvious feelings of home and country**, which is very good, and the movie shooting is also very good, which suddenly pulls us into the distance between us and Hollywood science fiction.

We all know that science fiction movies have always been Hollywood's specialty, whether it is "Avengers" or the interstellar series, they are all talked about by people and bring people a visual feast one after another, and the names of these science fiction movies are also well-known to many people, and now some netizens compare "The Wandering Earth" with Hollywood science fiction movies, and then express their opinions that "The Wandering Earth" has no scientific basis, and promoting the earth is self-destruction, their opinion is that the interior of the earth is a liquid substance with high temperatures, Just like eggs, if external pressure is applied to push the earth forward, it may cause the earth to crack like an egg, and the internal material will flow out, causing all kinds of unavoidable disasters, and eventually leading to the early extinction of human beings, so is this statement reliable? <>

Speaking of the beginning of the plot and some ideas in "The Wandering Earth", it is probably not possible scientifically, or with the science we currently know, it is not possible, ** in China, we humans have mastered the ability of heavy nuclear fusion, which is used on planetary thrusters, but the maximum energy of our current thrust is 20 million Newtons, if we want to reach the thrust of the movie, that is, it is 10 billion times the current one, besides, it will take time for us to stop the earth, which is longer than we imagine, It takes 600 years, which is 6 centuries, and there are many planets in the movie that strike to stop the Earth from turning, but these engines must be continuous and provide the same reverse thrust. <>

So we see that this difficulty is very high, for the earth human beings are almost impossible to do, and the earth stops rotating, the sea water will cover most of the land, we humans live underground is also very dangerous, because we have to face the phenomenon of ground collapse at all times, and our atmosphere will gradually disappear, the earth's magnetic field will slowly disappear, the earth is completely under the solar storm, the harm to human beings is very great, so it is almost impossible in science.

But we have to admire Da Liu's imagination.

I think it's very good to wander the earth, but you may encounter danger in the process of wandering.

It works scientifically because a lot of impossible things can happen.

I think the film is very good, well-made, and should work scientifically because science moves fast.

First of all, if the wandering earth really begins to implement, then our earth's atmosphere will be the biggest problem facing mankind, we don't have to consider some other factors, just say that because the earth stops rotating, the temperature changes sharply, at this time there will be an immeasurable meteorological disaster, it is likely that there will be extreme storms, and the earth's engine is likely to be destroyed directly.

At the same time, as the earth begins to cool down, the changes in the polar regions will be more drastic, and even the final two levels will produce an unimaginably large extreme air current, so that every part of the earth will be greatly affected, and even the earth's crust will be lifted, and no one will survive after that.

When the Earth reaches Jupiter, a greater catastrophe will come, in fact, as long as it is relatively close to Jupiter, it will happen! What kind of disaster is it? The beauty Xiaoqian personally believes that it is a catastrophe of tidal locking, and when the earth will trigger a huge volcanic eruption, such a scale is estimated to have never been seen in the history of the earth.

Large-scale volcanic eruptions will intensify as they approach Jupiter, and the entire Earth will become a fire field. We can look at the moons around Jupiter to know the answer, due to Jupiter's huge gravitational effect, the earth will also be squeezed differently, and then all the equipment and human beings on the earth will be threatened, and without reaching Jupiter, human beings will basically face extinction.

What's more, the so-called flight close to the speed of light in the movie, you must know that when the earth's material accelerates, it will also accelerate the loss, and maybe when we can't reach other habitable planets, the earth will be left with an empty shell. However, the wandering earth tells us a truth, that is, cherish our earth, instead of wandering with the earth, it is better to protect our earth from now on.

First of all, the temperature of the earth will drop very deeply after leaving the sun, which doesn't matter, we humans can take artificial methods to heat up the earth and hide in the dungeon, but the following points are more difficult, if you want to push the earth, you have to stop it from rotating, otherwise you want to push an object It is rotating, how can you push it to the designated place, but after stopping the rotation, the earth will have a series of disasters, which is even greater than the disaster of the 2012 movie. In my personal opinion, there is a way, that is, all mankind collectively build a space station in space and wait for the disaster to return to the earth, but the earth at that time is no longer the original earth, the magnetic field and atmosphere are almost gone, and there will be different air currents in space that will radiate to the earth and affect the survival of life. Liquid water has long been mixed with ocean magma and can no longer be drunk, even if the earth can still survive, the controllable nuclear fusion ion electric propulsion engine engine engine that wants to push the earth and force the earth to stop rotating has tens of thousands of engines in the movie, a total of 15 trillion tons of thrust, it should be possible to push the earth, but in reality, in addition to its own gravity, it is also subject to the gravitational pull of the sun, and if you want to push the earth away from the gravitational force of the sun, you have to multiply tens of thousands of times, and it is stones that burn, If you really use this kind of engine to push the earth out of the sun's gravity, you need to dig the earth through 40 meters, not to mention the next long wandering journey, you can use the slingshot effect of Jupiter Saturn to accelerate, but Jupiter's gravity is greater than that of the Earth, and if you don't get into these two planets, you will be torn apart.

Moreover, some experts say that if the earth is forcibly pushed, the earth's plates are very thin, and it is very likely that the forced push will also cause natural disasters such as plate displacement and rupture.

"The Wandering Earth" should be realized, but this is a long, long time, wait and wait, one day it will be realized.

The sun has played an important role in the success of human beings on Earth. But has anyone ever thought that if the earth breaks away from the sun and becomes a "wandering planet", will the humans on the earth be able to survive?

It can't be realized at the moment, engine technology is a big problem, and the fuel problem can't be solved, in fact, heavy element fusion does not release energy, but absorbs energy, which is also the pseudoscience of this science fiction **. If the gravitational tugboat method is used instead, it may be possible. As for the strength of the earth's crust and mantle, it is not a problem at all, a needle is easy to pierce **, a needle cannot pierce **.

"The Wandering Earth" cannot move the earth.

You must know that the gravitational force of the sun is actually to the 22nd power, and its driving force is equivalent to 150 trillion forces, which cannot push the earth at all compared to this data. Not to mention launching it out of the solar system, of course, the main purpose of the film is to make us realize that humans need to protect the environment, or at least we humans will suffer the consequences.

The engine used in the film is actually the ion propulsion engine in real life, and I know that this kind of propulsion has been used as early as in the aerospace field, for example, China's Long March 11 is the ion electric propulsion engine used. With the continuous development of our human science and technology, the speed of the engine will be faster and faster, and the speed of propulsion will be faster and faster.

The principles that drive the earth

The force that propels the aircraft to motion, which is the resultant force of various forces acting on the inner or outer surface of the engine or on the thruster. In a propulsion system with a propeller, the propeller pushes the air to flow in the opposite direction of flight, and its momentum increases, creating a reaction force on the propeller, i.e., thrust. The propeller is often mounted in front of the engine, so it generates the force that pushes the aircraft forward, also known as the pulling force.

The thrust of a jet engine is generated by a direct jet of high-velocity airflow in the opposite direction of flight, and the maximum gas temperature of the engine directly affects the exhaust velocity. In the general working condition, the higher the gas temperature, the greater the thrust of the engine, and the greater the mass flow through the working fluid of the engine, the greater the thrust of the engine. Under standard atmospheric conditions at sea level, the thrust generated by the engine when the aircraft is at rest is called sea level static thrust.

Because Jupiter's gravitational pull is so strong, the Earth times Jupiter's gravitational pull captures.

In the near future, scientists have discovered that the sun is rapidly aging and expanding, and the entire solar system, including the earth, will be swallowed up by the sun in a short period of time. In order to save themselves, human beings put forward a bold plan called "The Wandering Earth", that is, to build tens of thousands of engines and steering engines on the surface of the earth with global efforts, and push the earth out of the solar system and run to another habitat in 2,500 years. Liu Peiqiang (played by Wu Jing), a member of China's aviation industry, went to the International Space Station when his son Liu Qi was four years old, and shouldered the responsibility of navigator with his international peers.

In the blink of an eye, Liu Qi (played by Qu Chuxiao) grew up, and he took his sister Duoduo (played by Zhao Jinmai) to secretly run to the surface and steal the transport car of his grandfather Han Ziang (played by Wu Mengda), but he was not only arrested, but also suffered a global engine shutdown. In order to repair the engine and prevent the Earth from falling into Jupiter, the world began to rescue with saturation, and even Liu Qi's car was forcibly recruited. In the race against time, countless people have followed one after another, desperately trying to continue the hope of survival for hundreds of generations ......
