Stop it, boss, I’ve never seen a movie made like this.

Chapter 239 239. What a wonderful idea!

However, Chen Li's behavior was precisely out of scientific rigor.

It’s not like they haven’t been involved as consultants for other science fiction movies before, but those people just wanted to find a scholar to endorse them.

As for whether the content of the script is reasonable or not, it doesn't matter, they don't care.

This also made their cooperation with science fiction films not very pleasant, but Chen Li was different. As a director and screenwriter, he devoted a lot of time and energy to research the feasibility of the ideas in the movie.

This is very admirable. Such directors have the same concept and it is very comfortable to work together.

Another scholar was obviously very excited and urged: "Keep going. Using the formula m01v1=m2v2 to calculate, the propellant-free propulsion ejects a plasma beam at a speed of at least a hundred times that of the rocket engine! Since the power and fuel have been solved, then It’s time to discuss how to fly and where to fly?”

The astronomer laughed and said: "The sun emits heat outwards through the fusion of internal hydrogen nuclei. If it weakens, helium flashes will occur, and the explosion will be very large and sweep across the solar system. Unless the earth can escape from the solar system, everything will be Useless effort.”

"But it is basically impossible to push the earth out of the solar system in a straight line, because there is still gravity and orbit. I suggest using the concept of Hohmann transfer orbit, which is a method of changing the orbit of a spacecraft. Only two engine thrusts are needed along the way. Relatively fuel efficient."

Because it involves cross-field content, even Professor Zhang Yizheng is a little confused, so astronomers are going to explain to everyone what the Hohmann transfer orbit theory is.

Unexpectedly, Chen Li nodded: "As I thought, the earth escaped from the solar system not by flying out all at once like throwing a javelin, but by throwing a discus in a circle, that is, the earth revolves around the sun in a circle. The orbit gradually adjusts to an elliptical shape, which can lengthen the distance from the sun!"

People around were dumbfounded.

Oh my god, we don’t even understand yet, but you already understand what it means?

The astronomer was shocked. She refused to admit defeat and said, "Could it be that Director Chen has already concluded that for a star as big as the Earth, it is not enough to orbit the sun once in an elliptical orbit? According to orbital mechanics, it is at least necessary."

Chen Li said firmly: "15 elliptical revolutions, each time slowly accelerating. The flatter the ellipse, the further away from the sun."

Astronomer: "."

She gritted her teeth and continued: "Don't forget that the earth itself is still a matter of rotation."

Chen Li smiled and said: "Of course, we need to use the engine nozzle to fix the opposite direction of the earth's rotation first, and then use the equatorial engine's reverse injection to stop the earth's rotation. I estimate that this process will take 42 years."

Hiss hiss.

Everyone: "."

No, are all the young people today so scary?

She just asked, she didn't even count it yet, the other party even knew the number? Can it be more exaggerated?

You must know that when it comes to the motion of celestial bodies, it is often impossible to calculate it manually. Only by simulating the running status and spatial distribution of stars through computers can we know the best path.

The scene was completely silent, and everyone felt suffocated and deeply frustrated.

Damn, I haven’t felt like this in years.

Zhang Yizheng coughed and changed the subject without leaving a trace: "What about the earth being used as a spaceship to carry people, but where is the destination? You can't fly aimlessly, right?"

This question successfully attracted everyone's attention.

Chen Li picked up the pen and continued to draw patterns on the paper, saying: "Since the sun is gone, of course we still hope to find a replacement. I think Proxima Centauri is good."

This is consistent with what everyone present thought, because only Proxima Centauri in the constellation Centauri is the closest to the solar system, 4.3 light years away, and has the possibility of operation.

"Well, Proxima Centauri has been detected a long time ago. Similar to the sun, there are three planets around it. Among them, Proxima Centauri b is very similar to the earth, with sea water, land and tides, so some scholars have inferred that, There are very likely traces of life on this planet.”

"However, it is still very difficult to completely take the earth out of the solar system and into Proxima Centauri, because no matter how far the orbit is, as long as it does not leave the solar system, it will definitely be pulled back."

"And even if it's 15 times, it's impossible to escape the limit of the sun, right?"

Everyone fell silent for a while, and things reached a deadlock.

While everyone was thinking hard, Xu Wei asked curiously: "Director Chen, do you have any ideas for this step? How to completely leave the earth?" Everyone raised their heads and looked at each other, although they didn't think that the other party even had a way to leave the solar system. But let’s listen and see what you have to say.

In their hearts, they already regard this young man as a person of the same level.

Chen Li smiled: "Jupiter, gravity slingshot!"

"!!!"

"Fuck!!"

As soon as these words came out, several people present couldn't help but curse.

Wonderful!

How wonderful! !

The astronomer clapped his thigh and stood up directly, and said with high spirits: "This method is tailor-made for this plan. I finally understand why Director Chen emphasized 15 Hohmann transfer orbit revolutions. 15 times should be just enough." Reaching the outer reaches of Jupiter.”

"Jupiter's mass is 318 times that of the Earth. As long as it gets nearby, it will be pulled by its gravity. At this time, the Earth will gain a large escape velocity and enter the orbit of Jupiter, and then"

She said with great emotion: "Then, using the earth's own speed plus the orbital speed of Jupiter, it gracefully rotates half a circle in the orbit of Jupiter, and then throws it out like a discus, completely leaving the solar system!!"

“What a wonderful idea!!”

The astronomer's words continued to impact everyone's brains, like being struck by five thunders. Everyone was dumbfounded and their scalps were numb.

"Really?"

"Oh my God, how could such a ridiculous plan be implemented in just a few words!"

"Let me go, is this the charm of hard science fiction?"

"I don't know why, but I was so excited and trembling all over."

"Oh my god, I just want to cry to death. It's so tragic."

"."

For a moment, the office was extremely agitated, and this academic discussion reached its peak at this moment.

Everyone was amazed and looked at Chen Li with admiration.

If this guy didn't make movies, he might still be successful in scientific research. His brain is too flexible! !

Xu Wei, who had been watching, asked curiously: "The earth can be attracted and pulled by Jupiter, so why is it not pulled when it is close to Venus and Mercury on the other side of the sun?"

The astronomer laughed and said: "Silly boy, because those two planets have no atmosphere."

Xu Wei was stunned and smiled awkwardly.

Zhang Yizheng took out a breath and said with emotion: "Director Chen, is this the overall plan of wandering the earth?"

Chen Li nodded and said solemnly: "Yes, the Wandering Earth Plan is divided into 6 steps. It will take a total of 2500 years and require the efforts of dozens of generations to be realized!"
