The Science Fiction World of Xueba

Yao Bingxia frowned and said, "You mean, the intersection of earth and wood may be dangerous? Why haven't I heard of it?"

Pang Xuelin said: "When the Earth and Jupiter meet, the shortest distance between the Earth and Jupiter is less than 70,000 kilometers. The strong gravity of Jupiter is likely to have a major impact on the crust, which will cause a large-scale shutdown of planetary engines. Jupiter also has an influence. Once the mass of Jupiter shifts, it will cause changes in the gravitational force of the earth and wood, and may even cause the earth's orbit to shift...Using Jupiter to accelerate the earth is actually a gamble for mankind. If the bet wins, then mankind will Having passed the biggest crisis before the solar helium flash, if the bet loses..."

Pang Xuelin did not continue, Yao Bingxia also understood what he meant.

If they lose, it will be a catastrophe for both the earth and human beings.

Pang Xuelin said: "This news is still in the confidential stage. The last time the earth crossed the asteroid belt, human casualties were heavy. The spaceship faction took the opportunity to provoke trouble, causing large-scale riots in many underground cities, and almost took away several underground cities in North America. It has only been a few years since the earth passed through the asteroid belt. If this news spreads now, it may cause panic. If the spaceship faction jumps out again, the coalition government may not have much energy to deal with it... …Now our scientific team is trying to solve the crisis that may be caused by the intersection of earth and wood, please remember not to spread this news!”

Yao Bingxia nodded and said, "Don't worry, I understand!"

...

After eating and taking a bath, the young couple had an in-depth communication for more than an hour like a man and a woman in love. Yao Bingxia fell asleep in satisfaction, but Pang Xuelin couldn't sleep.

After working in the Earth Science Committee for so many years, Pang Xuelin has a deeper understanding of the Wandering Earth Project and the coalition government.

In the movie, when humans dealt with the Jupiter crisis, they seemed panicked and disorderly. In the end, the coalition government even voluntarily gave up the self-rescue operation, but let MOSS execute the fire plan and escape directly with the navigator space station.

If it weren't for the recklessness of the protagonist, father and son, there would be no possibility of the earth being rescued.

Pang Xuelin originally thought that this was because the coalition government was not prepared enough for the crisis that might be caused by the intersection of the earth and Jupiter, but when he was actually in it, he realized that the coalition government was more sensitive to this crisis than he imagined. Also pay attention.

The earth wants to use Jupiter's gravitational slingshot effect to accelerate, which is far more difficult than ordinary probes using Jupiter to accelerate.

The reason is simple. Although the earth is still a small guy compared to Jupiter, a giant system has been formed between the two.

Its massive gravitational effect will have a major impact on both planets when they meet.

Therefore, humans must design an extremely precise orbit.

If the orbital altitude is too high and the acceleration is insufficient, then the earth may not be able to escape the explosion range of the solar helium flash.

But if the orbital height is too low, there is a risk of the two colliding.

Therefore, how to grasp the degree is extremely difficult.

In fact, the research on the intersection of earth and wood has already begun as early as the initial stage of the Wandering Earth Project.

Over the years, the coalition government has launched a large number of probes to conduct comprehensive detection of Jupiter.

There are even attempts to send probes through the interior of Jupiter to detect the operating mechanism of Jupiter's internal structure, but often these probes will completely lose contact after they penetrate a thousand kilometers into Jupiter's atmosphere.

Therefore, at present, human beings' understanding of Jupiter is still quite rough, and a mathematical model of Jupiter's gravitational field has been preliminarily established only through detector observations.

However, there is a big problem with this mathematical model.

There are many reasons. First of all, the atmosphere of Jupiter is not as smooth and quiet as the atmosphere of the earth.

Once the distance between the probe and Jupiter is shortened to a certain range, the airflow overflowing from Jupiter's atmosphere will disturb the probe, causing the probe to drift in orbit around Jupiter.

If the theoretical orbit of the detector is an ellipse, then the actual orbit of the detector is an ellipse composed of wavy curves.

In addition, the orbit of the probe is also affected by the gravity field of the sun, Jupiter’s satellites, and other planets in the solar system, so the accuracy of the data of Jupiter’s gravity field detected by the probe can be imagined.

Secondly, whether it is for terrestrial planets or Jupiter-like planets, their gravitational fields will fluctuate over time.

This is because whether it is the geological movement inside the terrestrial planets or the rotation movement of the fluid inside the Jupiter-like planets, it will cause the internal density of these stars to change. Data will also vary.

If there are only these two problems alone, it is okay to say, even for ordinary probes that want to use Jupiter to accelerate, these two are not a problem.

But the earth is different.

Although the volume of the earth is only 1300th that of Jupiter, the gap between the two is not exponential, especially when the distance between the two is only hundreds of thousands of kilometers, the gravitational field of the earth will also It has a major impact on Jupiter, causing major changes in the density and distribution of matter inside Jupiter, which in turn causes changes in the gravitational force between Jupiter and the Earth.

This is also the reason why Jupiter's gravitational force surges by 9% when the earth and wood meet in the wandering earth.

On the other hand, Jupiter's gravity will also have an impact on the major plates of the earth.

In the field of geophysics, countless papers on this research are published every year.

In recent years, due to the existence of planetary engines, the crust of the earth has become fragile, geological disasters have occurred frequently, and even because of the liquid magma layer between the crust and the mantle, the plates have shifted greatly.

Just like the big earthquake that happened in Jiangcheng that year, Shanghai, which was originally located in the northeast of Jiangcheng, has drifted to the north of Jiangcheng.

This is also the reason why the protagonist's team passed through Shanghai when they went to Jiangcheng in the movie.

The gravity of Jupiter will undoubtedly aggravate this effect, and even cause a large-scale shutdown of planetary engines.

Therefore, no matter from which point of view, the earth uses Jupiter to accelerate, which is a hell gate for human beings.

After breaking through, it is a vast sea and sky.

If you can't break through, the whole group will be wiped out.

Until now, both the science committee and the coalition government have been taking this big gamble.

As for letting the crisis happen and then praying that the earth will be finally rescued like in the movie, Pang Xuelin has no hope.

Although the movie "The Wandering Earth" is wonderful, the biggest scientific bug is that at the end, Liu Qi and his son ignited Jupiter's atmosphere, causing the shock wave generated by the mixed combustion of hydrogen and oxygen to push the earth away from Jupiter's gravitational range.

No matter from which angle you think about it, this idea is impossible to realize.

Just relying on the chemical energy produced by the deflagration of hydrogen and oxygen to push the earth, it is as incredible as a person standing on the surface and farting himself out of the atmosphere.

Therefore, if you want to successfully escape this crisis, you must make sufficient technical preparations before the intersection of earth and wood!
