Planet Escape

In the dark and silent universe, countless asteroids are advancing rapidly under the influence of gravity.

Suddenly, an asteroid changed its trajectory and collided with another asteroid strangely, causing the other asteroid to deviate from its orbit.

After the asteroid deviated from its orbit, it slammed straight into a planet two-thirds the mass of the earth.

In the silent universe, this star, which has condensed the interest of the core, was directly smashed to pieces by the huge asteroid, and the power of the planet's explosion directly increased the speed of the star's wreckage to a very terrifying level.

These planetary debris flew into the Oort cloud and collided with meteorites, comets, asteroids and other celestial bodies. After repeated collisions, countless comets and asteroids broke away from the scope of the Oort cloud and rushed directly to the solar system internal.

This series of complex changes finally caused interstellar matter more than three times the mass of the earth to rush into the inner solar system. No one can imagine that this terrible change, which can be called a disaster, is only caused by the change of the trajectory of an asteroid and a simple impact.

-----

"boss,

Countless meteorites and asteroids flew out of the Oort cloud, with a total mass more than three times that of the earth. These meteorites and asteroids are currently flying towards the solar system. "

Xiang Gan looked at the countless meteorites and asteroids flying towards the inner solar system displayed on the screen, without any surprised expression on his face, this matter has long been expected by him.

"Starry sky, how much is left to calculate the distance between Proxima Centauri and the solar system?" Xiang Gan looked at the screen for a while. asked suddenly.

"Boss, Proxima Centauri is still 3.1 light-years away from the solar system." Xingkong quickly gave the answer.

"Xingkong, ask Teacher Li. Has the final design plan for the planet's gravity engine come out?"

"Boss, Academician Li said that the final plan has been made, and he is preparing to conduct a space gravity-free simulation experiment. The estimated time for the experiment is one year."

The one-year experiment time, plus the modification of the design drawings, the adjustment of the earth's orbit, and the preparations before acceleration, can't be done well in three or four years.

After these asteroids rush into the solar system now, they will cause chaos within the solar system. At that time, countless meteorites and asteroids will rush to the earth every day.

This is nothing, but ten years later. Among these asteroids, a massive asteroid will hit Saturn directly, and then it will be a disaster.

After the entire Saturn was hit, the total energy erupted exceeded petaton tnt equivalent. At that time, Saturn's mass ejection and ray burst will definitely mess up the interior of the solar system.

At that time, the earth didn't have to do anything else every day, just intercept asteroids and meteorites every day.

And then thirty years later. If the earth has not left the solar system, then a supermassive satellite will directly hit the sun, break through the sun's troposphere, and cause a large amount of material ejection inside the sun.

At that time, the interior of the solar system was basically unable to survive. It can be said that 30 years was the last time for the earth to leave the solar system. If the earth has not left the solar system within 30 years, then quickly abandon the earth and fly away from the solar system, because at that time the interior of the solar system will be hell.

Xiang Gan knows all about these things. But unable to change. That's right, human beings today have indeed entered the category of third-level civilization. But it can only intercept these asteroids that have already erupted, but there is no way to prevent the eruption of these disasters.

Because these disasters are all controlled by a kind of rule. Even today Xianggan builds a large space fortress outside Saturn to prevent Saturn from being hit by asteroids.

But Saturn is fine, and Jupiter may become the target of impact, even if Xiang Qian protects all planets such as Saturn, Jupiter, and Venus. Then the final catastrophe may evolve into the instability of the inner core of the sun, which will directly erupt.

In short, these things are clearly known to happen. But it is powerless to change, and can only rely on prophetic memory. Prepare in advance, avoid the danger before it comes, instead of preventing it.

So after Xiang Gan thought for a while, he decided to speed up the development of the gravitational engine. After all, the sooner he leaves the solar system, the sooner he will be out of danger.

"Xingkong, inform Yingying to ask the teacher for leave after school at noon, and not to go to school in the afternoon. At the same time, ask Yang Guang to send someone to pick up Yingying and send her directly to the Academy of Sciences." Xiang Gan said to Xingkong.

"Okay, boss."

After Xiang Gan finished speaking, he continued to process the documents in his hand. Most of these documents required his signature to take effect. Although this is a bit annoying for Xianggan, there is no way to let others replace it, nor can others replace it.

After approving all the issues related to the formation of the federal fleet and the training of soldiers, Xiang Gan left the office and went to the Academy of Sciences.

"The power of the gravitational device is increased by 35%, the constant central gravitational field...stops, and the moon's orbit changes, and the simulation experiment fails."

"I feel that the gravitational force between the moon and the earth must be shielded, otherwise the gravitational balance between them cannot be grasped at all."

"I disagree. Shielding the gravitational force between the moon and the earth will cause unknown changes to the earth. Such changes may have very serious consequences."

As soon as Xiang Qian entered the gravitational engine laboratory, he saw a group of people discussing in front of the big screen.

"Teacher, Professor David, what's the problem?" Xiang Gan looked at the motivating discussion of a group of people there, and asked curiously, didn't Xingkong just say that the final plan has been determined, is there any problem again.

When everyone saw Xiang Gan, they immediately greeted him, and Xiang Gan nodded.

"Originally, the plan has been determined, but we have overlooked a problem, that is, the gravitational force between the moon and the earth. In the current simulated plan, once the gravitational force generating device is activated, it is necessary to balance the gravitational field between the gravitational force generating device and the earth balance.

If the gravitational field can be balanced, then there will be problems in the direct gravitational transmission between the moon and the earth. Lost the gravity of the earth. The moon will leave the earth's orbit.

But if the gravitational field between the earth and the moon is not balanced, then the earth will be violently reacted by the gravitational field conflict, and the internal structure of the earth will change. Global fire eruption and continental shelf plate drift will be staged again. "Old man Li saw Xiang Gan, pointed at the screen and said to him.

Xiang Gan frowned as he looked at several large areas of gravitational field on the screen.

"What if we shield the gravitational transmission between the moon and the earth, but pretend a super-large planetary engine on the moon so that the moon will not leave the earth's orbit, and after we leave the solar system, can we restore the gravitational force between them? Xiang Gan thought for a while and said.

"No. The gravitational force of the moon on the earth affects the earth all the time. To put it simply, the tidal change of the earth is affected by the gravitational force of the moon. There are many other unknown effects. If the earth suddenly loses the gravitational force of the moon, then What changes will happen. We don’t know.” After hearing Xiang Gan’s words, one person said immediately.

When Xiang Gan heard it, what they said made sense. He was not sure whether the loss of the moon's gravity would have any impact on the earth's environment. If there were any unpredictable changes, it would be over.

"Okay, let's have lunch first, and we'll talk about the experiment in the afternoon." Xiang Gan thought for a while. I didn't think of any good way, so I can only tell everyone.

"Why do you run here every day? Don't tell me you're free? After everyone has dispersed. Old man Li said with a sigh.

"Where am I free, I'm in a hurry. If I finish manufacturing the planetary gravity engine in one day, the earth will not be truly safe." Xiang Qian said speechlessly.

"Is there any danger?" Old man Li said with a frown.

"It's not that there are any dangers, but there are still many dangers. But at present, getting the earth out of the solar system is the most important thing, as long as this thing is completed, other things are easy to talk about."

"How long do we have?" Old man Li asked seriously.

"If you don't leave the solar system within 15 years... within 15 years, the earth will be in danger. If you don't leave the solar system within 30 years, we can only abandon the earth. If you haven't left the solar system within 50 years, you can only wait to die "Xiang Gan looked around and found no one, so he whispered to old man Li.

"Why do you insist on taking the earth out of the solar system? In fact, with our current technology, we can find another planet suitable for human habitation. Why..."

"Teacher, I know what you said. But I have my reasons for doing so." Xiang Qian said seriously.

"Okay, I understand." Old man Li knew Xiang Gan's determination when he saw Xiang Gan's expression.

"Teacher, don't worry, I'm fine. I'm here today to solve your problems. Now we're going to eat and work in the afternoon." Xiang Gan said confidently.

After lunch, Zhang Ying came to the Academy of Sciences under the escort of biological weapons.

"Yingying, do you still remember the prophecy scene yesterday? What did the moon look like at that time, and is there anything around?" After Zhang Ying arrived, Xiang Gan asked directly.

"...Brother Xiang Gan, I forgot that." Zhang Ying said unconsciously.

"It's okay, you can predict now, see if there is anything on or around the moon, and what those things look like." Xiang Gan said with a smile.

"Okay, Brother Xiang Gan." After Zhang Ying finished speaking, she activated her ability.

Five minutes later, Zhang Ying panted and said, "Brother Xiang Gan, there is a big tower on the moon, and there are many 'big iron plates' around the moon."

After Xiang Gan finished listening, he glanced at old man Li, and continued to ask, "Yingying, have you seen what Earth Ten looks like?"

"The earth... I saw it, and nothing has changed." Zhang Ying thought for a while and said strangely.

"Teacher, you should study it based on this. I feel that the moon's gravitational force should be shielded, but it doesn't use a planetary engine, and it still revolves around the earth." Xiang Gan said slowly.

"It's not that simple, I have to go back and think about it." Old man Li said with a frown.

"Well, I can't help you in this regard, if you have any questions and don't know what the consequences will be, just ask Yingying directly, and I'll go back first.

Yingying, you are here to eat snacks and watch movies, and I will send someone to take you home in the evening. I have to listen to Grandpa Li's words here, you know. After Xiang Gan explained to Zhang Ying, he turned and left.

In the next few days, Zhang Ying went to school every morning, and came to the Academy of Sciences in the afternoon to help with scientific research. With Zhang Ying's joining, many questions that were uncertain, under Zhang Ying's accurate prediction, everyone passed it directly.

Just like the impact of the gravitational field on the earth, after deciding on a plan, Zhang Ying would predict the situation on the earth, and after confirming that it would not cause any serious consequences, everyone decided on the plan.

In this way, the speed of research is many times faster than before, and new problems are overcome every day.

Although everyone only knows the results of these problems, they don't know why such results are produced. But under Xiang Gan's instruction, everyone didn't waste time to study these questions, they just stored these questions and moved on to the next question.

During this period, Xiang Gan paid close attention to the group of asteroids flying out of the Oort cloud every day. Instead of stopping it, he pays attention, and any meteorites and asteroids that threaten Earth are flagged. (to be continued)
