Annihilation of the solar system

Because of his outstanding contribution to extraterrestrial invasion early warning information, Xia Jigang became the president of the National Academy of Sciences as he wished. Xia Lan, Wei Xu and their teams were assigned to the Earth Defense Program Research Institute. Xia Lan was the one below the institute.

The person in charge of the Space Defense Research Program Branch. The members of this organization are their five classmates who worked on the sky survey project together at the National Astronomical Observatory.

The discovery of picometer-level gravitational waves behind Jupiter directly confirmed the correctness of Liu Chaowen's theory. Originally, this discovery was enough for Liu Chaowen to win the Nobel Prize. However, with the advent of the crisis era, such activities that had no practical effect on the defense of the earth were stopped. Although

Both the country and EDA wanted the talented young man who first raised the alarm to participate in the substantive defense plan. However, he expressed his hope to continue engaging in theoretical science research, and in the end he continued to do theoretical research with his mentor Zhou Cheng.

Physics-related research work.

In the office of the National Academy of Sciences, Liu Mengzhu and Wu Fan both stared at the report on the TV on the wall of the office. Xia Lan and Lin Tianyu were busy with their own affairs at their desks, and Wei Xu had one arm around his arm and another holding his hand.

After work, I stared at the various satellite photos and infrared images that were fully booked on one wall of my office.

A month ago, the world's top observation equipment and scientists described a desperate picture for all mankind that gradually unfolded in front of people - alien civilization is using a kind of equipment and technology that is still unknown.

Controls the evolution of the original organisms on Europa and Titan, and this process has been going on for a long time and is almost complete!

Wei Xu held his chin with one hand, stroking his thin beard, looking at the photos taken by the space optical telescope and infrared telescope that covered the entire wall, and said to himself:

"If we directly tell the whole world in a live broadcast that the attack we are about to face is an attack by billions of biological creatures, most people will probably collapse directly. The most primitive attack method is often the most terrifying, and it can easily destroy people.

The will. Just like the shock brought by a recruit shooting an enemy with a rifle on the battlefield and killing an enemy with a bayonet in hand-to-hand combat are completely different."

"Old Wei, can you please stop imagining such a bloody and terrifying picture? You don't know what is on Europa and Titan, so how do you know how they attack the earth! It makes everyone nervous.

Yes!" Liu Mengzhu complained with an unhappy look.

Wei Xu also realized that his groundless speculation had caused uneasiness to his colleagues, so he quickly changed the topic:

"Hey, senior sister. I remember that we proposed the 'Ark Plan' and the 'Fish Hidden Plan' when we attended the first EDA demonstration meeting, but they didn't seem to be mentioned in the televised speech."

Wei Xu's words attracted the attention of Liu Mengzhu, Wu Fan and Lin Tianyu. In the weeks before today's TV mobilization speech, the world's major national leaders held several demonstration meetings on the establishment of EDA in Beijing and New York, and Xia Lan

Wei Xu and Wei Xu participated in some of these meetings as experts.

"Yeah, I haven't heard you mention the EDA conference yet," Wu Fan said.

"What are the 'Ark Project' and the 'Yuzang Project'? Tell us about it, senior sister." Liu Mengzhu was also very curious and completely lost the emotion of blaming Wei Xu just now.

Xia Lan temporarily stopped the work of organizing information:

"The 'Ark Plan' proposed by Britain is to put some people and 30 million fertilized egg cells into a self-sustaining space station and hide in the orbit of an asteroid. After the ground battle is over, they will return to the earth. If the ground battle fails,

, all personnel will go into hibernation and take turns flying to the nearest habitable planet."

Wu Fan said angrily:

"They can really imagine whether the level of scientific and technological progress in more than ten years can meet the technical requirements. Let's not say who should go on the Ark to survive and who should stay to die. Who has the final say? We should not worry about the scarcity but the inequality.

Don’t they understand the reason?”

Xia Lan nodded:

"Well, when the 'Ark Project' was proposed, it was opposed by many countries. I think that in the subsequent demonstration meeting that we did not participate in, the plan should not have passed the demonstration. As for the assassin-like fish

The hiding plan' should have a confidentiality level, and we don't know the specifics."

Wei Xu looked back at the filtered optical photos with a resolution of less than one meter. Even ordinary people could see the strangeness. In the photos, one could vaguely see the surface of Titan, with densely packed mountains similar to those on Earth.

There are rows of ovulation sac structures distributed. The egg sac structure in the photo is about the size of a coin, and when converted to a scale, it is the size of a city on Earth.

If the optical photos are not clear enough, the disc-shaped high-temperature radiation sources under the thick ice cap of Europa in the infrared photos clearly show abnormalities.

"Senior sister, how confident do you think we can be in doing this?" Wei Xu asked solemnly.

Xia Lan heard Wei Xu's words and understood what he meant. What he wanted to express was whether it would be possible for humans to be ready to resist the invasion in more than ten years, but Xia Lan did not answer him. Because since the discovery of Omo

Mo Dao confirmed that an alien civilization was about to attack, and she participated in the entire process.

Although it is still unclear why the alien civilization attacks the earth in this way and the motivation for the attack, she is very clear that the gap between the technological level of the alien civilization and the earth cannot be made up in more than ten years, or even hundreds of years.

Just launching a spacecraft the size of "Oumuamua" into space would be enough for mankind to groping in the quagmire of science and industry for a long time...

She was lost in thought, with a gleam of fear in her eyes.

"Old Wei, you mean...what we are doing now may...may not have any practical significance?" Wu Fan's voice trembled, and he looked at Wei Xu like a terminally ill patient looking at his doctor.

, hoping that the doctor would tell him the hope of life.

Wei Xu's eyes gradually lost focus as he looked at the photos on the wall. He was always optimistic, but at this moment he couldn't say a word to comfort his companion.

He thought of Sisyphus in Greek mythology, the king who fought against the gods in order to eliminate death on earth. He pushed an extremely heavy boulder to the top of the mountain. And every time when he was about to reach the top of the mountain, the gods would let him

A huge boulder rolled down the mountain again, and Sisyphus continued to push the boulder to the top of the mountain in such endless despair, even though he knew that the final result might still be ineffective and desperate.

He felt that at this time, he, and even the entire human race, was doing something like Sisyphus.

A sad breath filled the office like the sound of a humming ventilator.

No one spoke for a while. Xia Lan suddenly stood up and continued to count the pile of information on the desk. She said to Wei Xu in a reproachful tone:

"We don't need to waste time on meaningless issues. We still need to figure out many situations now. What we have to do now is much more important than those baseless conjectures. I just went to a meeting,

The task assigned to us is to assist the "Fuyao Plan" of the Academy of Engineering. The specific task is to provide the initial theoretical maximum launch weight of a single module of the orbital space station. Although our department is relatively marginal in the "Fuyao Plan", we still have to do our best.

Work."

Hearing Xia Lan mention the Fuyao Project, Lin Tianyu's eyebrows moved slightly:

"The Fuyao Project really passed the review?"

Liu Mengzhu also recovered from the confusion just now. She showed an expression of joy like a girl seeing a rainbow for the first time:

"I really didn't expect that the plan that looked like it came out of myths and legends could actually pass the review. It's really romantic when I think about it!"

Wei Xu looked away from the wall covered with satellite photos, and his mood calmed down a lot:

"Actually, it's not that unexpected. Look at the plans that participated in the space material delivery plan review at EDA this time. Lao Maozi's meteor shower plan is simply to increase the size of the rocket based on the existing chemical rocket.

Then build hundreds of launch sites on the equator to achieve the supply capacity of space supplies."

Lin Tianyu didn’t seem to agree with Wei Xu’s opinion:

"This plan is a bit backward, but it is better than reality. Moreover, the early orbital launch of the defense plan cannot be separated from traditional rockets."

Wei Xu shook his head slightly:

"This plan has almost no technological advancement. It is true that it is easy to achieve. However, the amount of resources used is staggering, and it is always difficult to solve the problem of launching a large payload into low-Earth orbit efficiently in a single shot.

Let’s not talk about whether the 10,000-ton rocket they proposed can achieve technical reliability in a short time. Even if it can be built, it is difficult to say whether the current industrial production capacity of the earth can meet the needs of the near-Earth space defense program. For the past two years, it is temporarily

It’s okay to improve the space carrying capacity, but I definitely won’t choose the ‘popular plan’ for long-term space carrying.”

Wei Xu's point of view was indeed relatively objective. Lin Tianyu could not refute it, so he changed the topic:

"If you think about it carefully, the Tissot project proposed by Europe is too advanced. It builds a space station at an altitude of 1,200 kilometers, and then uses a space elevator to connect it to the ground station on the equator. It also uses steel cables to pull an upper station in a synchronous orbit 40,000 kilometers away.

Thousand tons of counterweights.

The stability of the space station, elevators and counterweights are not considered for now. If it is really built, the carrying efficiency will definitely be the highest among all space carrying plans. But according to our current technology, it is estimated that we will wait for alien invaders

We’ve all called. We haven’t built the space elevator yet.”

Wei Xu looked at a map of China on the other side of the wall. He looked at the plateau in the southwest known as the "roof of the world":

"So now the only ones that are more in line with our technological and industrial capabilities are the North American "Carmen Plan" with a 1,000-ton super-large transport aircraft as the mother aircraft and a 30,000-meter-high altitude aerospace jet as the core, and our "Fuyao Plan."

Already."

Wu Fan added:

"And there are strong complementarities between our plans. The "Carmen Plan" can be operational within half a year. This makes up for the vacuum period in the early construction of the "Fuyao Plan." After one year, the infrastructure of the Fuyao Plan will be completed.

Once put into use, Project Carmen can focus on transporting personnel and delivering medium and light equipment."

Xia Lan picked up the pile of packed information and walked to the filing cabinet. She put the information into the filing cabinet and said:

"Don't forget, the core mission of our department is to figure out the specific situation of the monsters on Europa and Titan and how they reached the earth.

From today on, everyone should not leave the research center unless there is something special. The time left for us, it should be said that the time left for all mankind is very urgent. We are now the group of people standing at the forefront of the confrontation, and we have shoulders

duty of......."

She paused, closed the door of the information cabinet, turned to look at everyone, and said two words in a deep voice:

"Very heavy."

Every word that Xia Lan spoke calmly hit everyone's heart. They all understood the current situation very well and knew better than anyone else that Xia Lan's words were not exaggerated. The atmosphere in the office became increasingly tense.

It became heavy. Only Wei Xu quietly walked back to his desk, took a mint candy from the table and put it in his mouth:

"You are just asking me to go back every day, and I have no place to go. The transportation system is all publicized, and the entertainment industry is closed. I can't find a place to hang out at the door, so I might as well stay here with you."

.

I just want to see what Liu Mengzhu’s pretty plain face looks like when her little foundation in the storage box is used up. Maybe everyone will think she has a new colleague.”

A paper ball hit Wei Xu on the head, and Liu Mengzhu cursed in his unique and somewhat artificial voice:

"Hate!"

The atmosphere in the office also relaxed with laughter.
