Annihilation of the solar system

In the south where there is no heating supply system, early winter nights are extremely cold.

Although Xia Lan's team's office is specifically allowed to use air conditioning for heating, the heating power cannot be fully turned on as before. It can only be said that there is a trace of warmth in the office. Wu Fan and Liu Mengzhu blow on their palms from time to time. Get up and rub your hands to keep warm.

It was almost eleven o'clock, and they had just persuaded their instructor Shen Manling to leave, who was working overtime together, but they themselves were still working hard at the moment.

Various optical, infrared and radio imaging pictures are displayed on each of their computer monitors, and these pictures are all telemetry pictures of Europa and Titan that were transmitted just a few hours ago.

Wei Xu took out a mint candy from the metal box in front of him and put it in his mouth, making sucking noises in the quiet office.

There was a "sizzling" sound and the sound of candy and teeth colliding. Wu Fan, who was sitting at the desk next to him, raised his head, pushed up his glasses on the bridge of his nose, looked at Wei Xu and said:

"Old Wei, what are you eating? You eat it every day, give me one to try!"

Wei Xu stared at the computer screen and did not turn to look at Wu Fan beside him. He just handed him the entire candy box. Wu Fan opened the box, took out one and put it in his mouth, and then let out a long and sharp suck. Breathing sound:

"Hiss...!" Then he quickly spit the candy into the trash can:

"Wei Xu, what kind of candy are you eating? Such a strong mint flavor!!! You still eat it every day, you can bear it!"

Wei Xu shook his head slightly proudly and continued to suck the candy in his mouth, and said leisurely:

"I think this tastes pretty good! You even vomited it, and you won't be able to eat this candy again after a while!"

Liu Mengzhu on the side said as if talking about gossip news:

"Didn't you realize that Wei Xu hasn't smoked in the past few months? He is eating mints to quit smoking. How can you stand eating mints with that flavor?"

Wu Fan was still breathing heavily to ease the strong mint smell in his mouth:

"Let me tell you, Lao Wei, I remember when you were a graduate student, you were addicted to smoking. Now you have figured out how to quit smoking?"

Wei Xu still said leisurely:

"In the past, it was not a problem to smoke a cigarette if you had a little money, but it is different now. Look at the cigarettes in the quota table, which are worth two standard meals. How can I afford that consumption? That's all. , that’s all, just quit.”

The mint in Wu Fan's mouth was almost gone, and he handed the candy box back to Wei Xu:

"That's not right. With your current body type, you should eat less. I think losing some weight is more important than quitting smoking. So when it comes to the day of the decisive battle, don't expect help from your body type. Just don't drag people back." Already."

Wei Xu turned around, put one hand on Wu Fan's desk, and stared at him:

"You said that I used to smoke, and you thought I polluted your air. Now that I quit smoking, you say I shouldn't quit. You friends are really hard to take care of."

Wu Fan originally wanted to say something, but Liu Mengzhu said first:

"Wu Fan, if you don't understand the situation, stop meddling in it. You've finished your own business."

Wu Fan looked confused, but he didn't ask any more questions. Lin Tianyu, who had been silent all this time, seemed to continue working calmly, but a trace of anger flashed out of the corner of his eyes.

A smile appeared on Xia Lan's lips, and she felt a little inexplicably moved in her heart.

I remember three months ago on the bench at the space center, Wei Xu said half-jokingly and half-seriously:

"It's hard to quit smoking."

Then she put the cigarette back into the cigarette case. She had not seen Wei Xu smoking since that night. Although she was not sure whether Wei Xu's smoking cessation was related to that night, there was inevitably a trace of it deep in her heart.

Thrilling. But the current serious situation left her with no extra energy to find the answer that seemed irrelevant now.

"I compared the optical and thermal imaging photos sent several times before. I found that there is a mesh structure growing on the surface of Titan! I speculate that it should be an evolved biological structure."

Lin Tianyu suddenly spoke, breaking the ambiguity that originally filled the air. The atmosphere in the office became serious, and everyone immediately returned to work.

Liu Mengzhu shook the lollipop in his hand that only had a stick left:

"I have also discovered it, and the thermal imaging pictures on Europa are particularly obvious. The clustered egg sac structures were originally separated by a certain distance, but now they seem to have begun to grow mesh structures close to each other. In the photo

It looks like roots stretching out all around."

She looked through other information on the table and said:

"Comparing the previous photos, it is true that they only started in the past month. This photo is particularly obvious. According to my calculations, they may connect the scattered egg sac structures within one to two years.

Come together.”

Xia Lan stood up and walked to the photo wall:

"This shows that the evolution process on Europa and Titan may be entering the next stage. We must now figure out what the next stage is. Moreover, I feel that it is very likely that the next stage will be with them.

How you get to Earth matters."

Wu Fan leaned his back on the table and chair:

"Although the escape velocities of Europa and Titan are only two kilometers per second and four kilometers per second, this is much lower than the Earth's requirement of 7.9 kilometers per second.

But I really can’t understand that with the power of biological flesh and blood, let alone entering the earth and the earth’s transfer orbit. It’s hard to imagine that they can even leave the surface of the satellite!”

Lin Tianyu still had the same cold expression:

"Don't underestimate the capabilities of living organisms. Let's not mention that life may exist on almost every large celestial body in our solar system. Just look at the creatures on our earth whose body functions are beyond the reach of us humans.

Ants can lift objects 5,000 times their own weight, some annelids can survive in the 350-degree heat of underwater hot springs, and tardigrades can be resurrected from dehydration like the Trisolaran in the novel.

There are many such extreme examples, and they are the result of natural evolution. You must know that the organisms on Europa and Titan have undergone directed evolution under external interference, which can even be said to be transformation. Their biological functions may be far better

Beyond our imagination.”

Liu Mengzhu looked at Lin Tianyu with admiration, like a nymphomaniac girl:

"Senior Brother Lin is amazing. His analysis is very reasonable!"

Everyone has long been accustomed to this junior sister who is obsessed with handsome men, so they didn't pay attention. Wei Xu said in a vague tone while sucking the high-power mint candy in his mouth:

"Europa does not have a fixed rocky surface, and most of their egg sac structures are in the ocean under the ice sheet. I can't see many clues. I can see some from the pictures of Titan.

It makes sense.

Combining the topographic maps of Titan drawn by the early Cassini and Huygens detectors and telemetry satellites before the crisis, coupled with the optical and thermal imaging photos of Titan we recently took. The pattern I discovered is...

..."

Speaking of this, Wei Xu himself felt that the unmelted mint candy in his mouth was a bit in the way. So he chewed the candy with a "click! click!" and swallowed it. Liu Mengzhu on the side was a little anxious:

"Go on, what kind of candy are you chewing at this time?"

Wei Xu swallowed the chewed sugar crumbs in big gulps. The strong smell of mint made him cough several times. It took him a while to calm down:

"Come and take a look!"
