The Science Fiction World of Xueba

Yao Bingxia frowned: "You mean, there may be danger in the intersection of the ground and the tree? Why haven't I heard anyone say it?"

Pang Xuelin said: "When the earth and the wood meet, the shortest distance between the earth and Jupiter is less than 70,000 kilometers. Jupiter's strong gravitational force is likely to have a significant impact on the crust, which will cause the planetary engine to stop on a large scale. Jupiter also has an impact. Once Jupiter's mass shifts, causing the gravitational changes of the ground and Jupiter, it may even cause the Earth's orbit to shift ... Using Jupiter to accelerate the earth is actually a human bet. If the bet wins, then humans will After the biggest crisis before the solar helium flash, if the bet loses ... "

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

If you lose, it will be a disaster for both the earth and humanity.

Pang Xuelin said: "This news is still in the secret stage. The last time the earth passed through the asteroid belt, human casualties were heavy. Spaceships took the opportunity to pick things up, triggering large-scale riots in many underground cities, and almost snatched several underground in North America. The control of the city is now only a few years before the Earth crosses the asteroid belt. If this news is spread out now, it is likely to cause panic. If the spaceships then jump out, the coalition government may not have much energy to deal with ... … Now our scientific team is trying to solve the possible crisis caused by the intersection of the ground and the tree. Do not forget to spread these news! "

Yao Bingxia nodded and said: "Relax, I understand!"

Uh ...

After eating and bathing, the young couple communicated as if they were in love with men and women for more than an hour. Yao Bingxia fell asleep in contentment, but Pang Xuelin couldn't sleep, and stared at the ceiling with his arms in a daze.

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, humans seemed panic-stricken when responding to the Jupiter crisis. In the end, the coalition government even voluntarily gave up the self-rescue operation, and just let MOSS execute the tinder plan and take the pilot space station to flee directly.

If it weren't for the protagonist's father and son, the earth would not have been rescued.

Pang Xuelin thought that this was the reason why the coalition government was not ready for the crisis that may occur after the confluence of Earth and Jupiter, but when he was really in it, he realized that the coalition government was more prepared for this crisis than he thought. Pay more attention.

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

The reason is simple. Although Earth is still a little guy compared to Jupiter, a giant system has been formed between them.

庞大 Its huge gravitational effect will have a significant impact on both planets when they meet.

Therefore, humans must design an extremely precise orbit.

If the orbital height is too high and the acceleration is insufficient, then the earth is likely to be unable to escape the burst of solar helium flash.

However, if the track height is too low, there is a risk that the two will collide.

Therefore, how to grasp the degree is extremely difficult.

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

In recent years, the coalition government has launched a large number of probes to carry out a comprehensive detection of Jupiter.

I even tried to make the probes pass through the interior of Jupiter to detect the operating mechanism of Jupiter's internal structure, but often these probes will completely lose contact after one thousand kilometers into Jupiter's atmosphere.

Therefore, the current human understanding of Jupiter is still quite rough. Just by observing the probe, a mathematical model of Jupiter's gravity field has been initially established.

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

There are many reasons. First, Jupiter's atmosphere is not as stable and quiet as the Earth's atmosphere. Once the distance between the detector and Jupiter is reduced to a certain range, the airflow overflowing from the Jupiter's atmosphere will disturb the detector, making the detector in orbit of Jupiter Drifting on the water.

If the theoretical orbit of the detector is an ellipse, 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 satellites and other planets in the solar system. The accuracy of Jupiter's gravity field data detected by the probe can be imagined.

Secondly, whether it is for terrestrial planets or wooden planets, their gravitational field will fluctuate over time.

This is because whether it is the geological movement inside the terrestrial planet or the rotation movement of the fluid in the terrestrial planet, it will cause the density of these stars to change. Therefore, the gravity field detected by the detector in different time periods and different positions The data will also change.

If only these two problems are okay, even for ordinary probes that want to use Jupiter acceleration, these two problems are not a problem.

But the earth is different.

Although the size of the Earth is only one-thirteenth percent of Jupiter, the gap between the two is no longer exponential, especially if the distance between the two is only hundreds of thousands of kilometers. It has a significant impact on Jupiter, causing a significant change in the density and distribution of matter inside Jupiter, which in turn causes the gravitational pull between Jupiter and Earth to change.

This is also the reason why Jupiter ’s gravity surged 9% when the earth and the wood intersected in Wandering Earth.

On the other hand, ~ www.readwn.com ~ Jupiter's gravity also affects the major plates of the earth.

In the geophysics community, countless papers on this subject are published every year.

In recent years, the existence of planetary engines has made the crust fragile, frequent geological hazards, and even a large deviation of the plate due to the liquid magma layer between the crust and the mantle.

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

This is why in the movie, when the protagonist team travels to Jiangcheng, they pass through Shanghai.

Suddenly, Jupiter's gravity will undoubtedly aggravate this effect, and even cause a large-scale shutdown of the planetary engine.

Therefore, in any way, the use of Jupiter to accelerate the earth is a ghost gate facing human beings.

I broke through, it was a vast sky.

I can't break through, that is, the whole regiment is destroyed.

Until now, both the Scientific Committee and the coalition government have been making this gamble.

As for letting the crisis happen, and then praying that the earth will be finally rescued like in the movie, Pang Xuelin didn't hope.

Although the movie "Wandering Earth" is wonderful, the biggest scientific bug is that the ending part of Liu Qi's father and son ignited Jupiter's atmosphere, so that the shock wave generated by the mixed combustion of hydrogen and oxygen pushed the earth out of Jupiter's gravity range.

No matter what angle you think about, this idea is impossible to achieve.

凭 The chemical energy generated by the hydrogen-oxygen deflagration alone wants to propel the earth, just like an individual standing on the ground, putting a fart and bursting himself out of the atmosphere.

Therefore, if you want to escape the crisis smoothly, you must make sufficient technical preparations before the ground and the trees meet.
