Let’s not talk about the distance, let’s talk about developing the entire solar system.
In terms of resources, it is not enough to rely solely on the resources on the earth.
Developing the solar system requires a lot of detectors, spacecraft and other related equipment, transforming other planets, building many space cities, etc.
These projects and projects require huge amounts of resources.
Such a huge amount of resources is unrealistic to rely solely on the earth, and needs to be mined and collected throughout the solar system.
Only in this way can there be sufficient resources to develop the entire solar system.
After talking about resources, next is energy, which in layman’s terms is energy.
This is easy to say. Now there is a light column project, and preliminary experiments have been successful.
With the completion of the light pillar project, the energy problem in the solar system will be solved.
But the sun cannot be extinguished.
In addition to the energy provided by the sun, there is also energy provided by fossil energy, nuclear fission and nuclear fusion.
With the development of science and technology, energy can also be obtained in more advanced ways.
Such as the annihilation of matter and antimatter, dark matter, dark energy, etc.
For now, controllable nuclear fusion is the most likely thing that humans can achieve.
It is no exaggeration to say that once humans achieve controllable nuclear fusion, humans will be able to obtain energy in the true sense.
At that time, humans will be able to get rid of the sun and explore the starry sky beyond the solar system.
The last thing is technology.
To be honest, technology is very widespread. In a sense, the only thing that humans can change is technology.
The quality of technology determines the difficulty and method of obtaining resources and energy, and also determines the environment and destiny of human existence.
It is no exaggeration to say that there are countless resources and energy in the universe, but technology needs to be accumulated bit by bit.
To put it bluntly, with technology, there will be no shortage of resources and energy.
This incidates that. Among resources, energy and technology, technology is the core.
What humans really need to do is to continuously develop technology.
The most important thing in developing technology is that more people participate in scientific research. Only in this way can technology achieve rapid development.
Su Zhe and others talked until the end, and they always believed that the most important thing for human beings to change is to develop science and technology.
As long as science and technology are advanced enough, humans will be able to resist and survive problems such as food shortages, changes in the earth's environment, asteroid impacts, solar mutations, etc.
While a few people were chatting, news came in saying that three people and two handheld imaging scanners from the moon base had arrived.
After Su Zhe and the other two put on their armored spacesuits, they arrived at the center of the awning, which is the edge of the ice cave with a diameter of one hundred meters.
The three who came with the four said hello.
Su Zhe and Fan Xiaoming flew down into the ice cave with several other people holding handheld imaging scanners.
The two of them hovered fifty meters underground, using handheld imaging scanners to continuously scan the ice walls of the ice cave.
"The purity of this ice layer is really high. Not to mention the large organic molecules, even the mineral salts are pitiful." Fan Xiaoming said, "Su Zhe! How are you doing there?"
"It's just like what you described, the purity is very high." Su Zhe replied.
"You two! Let's continue going down! The shallower the ice layer, the higher its purity." Zhang Gaoming explained, "The thickness of the ice layer where we are is three kilometers. So far, the depth has reached At 2.8 kilometers, with handheld imaging scanners, we may not be able to find traces of life."
Su Zhe and Fan Xiaoming nodded, probed at the same height for a while, and then continued down.
Every fifty meters down, the two of them would explore for a while.
As Zhang Gaoming said, the further down you go, the more inorganic salts and organic matter exist in the ice layer.
When he reached a depth of 300 meters, Fan Xiaoming shouted: "I discovered it. I discovered the existence of amino acids in the ice."
Fan Xiaoming shouted excitedly.
Several people gathered around.
At first glance, it turns out they are really amino acids.
But this is nothing surprising, because the presence of amino acids has also been discovered in the laboratory.
"It's true! But just like our investigation, amino acids were found in the ice at a depth of 300 meters. Judging from the structure of the amino acids, they are the same as the types of amino acids found in our laboratory." Zhang Gaoming said.
"Continue! Maybe we will make new discoveries." Xu Zhengping shouted.
Suddenly, Su Zhe shouted: "I have discovered a newly discovered amino acid in the laboratory. The most important thing is that this amino acid is difficult to form in nature, but it is easy to be biosynthesized. This means that this area of the ice layer There was life in the past.”
"Uh! That's right! Biosynthetic amino acids." Zhang Gaoming said in surprise.
The group of people gathered around Su Zhe again.
After looking at it for a long time, Fan Xiaoming said: "It's true! If you look at it this way, there must have been life on the moon in the past."
"This is true using the earth as a reference. It is also possible that the moon has a special environment and this amino acid is synthesized in the natural environment." Su Zhe explained.
At this time, Su Zhe stepped aside.
The researchers who followed took out their tools and began to mine the ice layer where this special amino acid was found.
Su Zhe and Fan Xiaoming continued down.
As the depth deepened, the two discovered amino acids that had not been discovered before many times.
At the same time, the content of inorganic and organic substances contained in the ice layer is also getting higher and higher, such as inorganic salts, oxygen, nitrogen, amino acids, etc.
】
Soon, the group arrived two kilometers underground.
Seeing that Su Zhe and Fan Xiaoming were busy detecting, Zhang Gaoming reminded: "We have done preliminary testing on the ice samples above two kilometers, but we haven't had time to test the ice samples below two kilometers."
The laboratory set up here is very crude, and with only a few experimenters, the speed of testing cannot keep up.
Even if the ice samples of more than two kilometers are sampled and tested, otherwise new amino acids will not be discovered.
"Lao Zhang! I said you should have told us earlier if you were short of people. Just you guys, if you want to figure out this ice layer, I really don't know how long it will take." Xu Zhengping said, "What are you doing? Delay things and delay mankind’s important discoveries.”
"Well, aren't we seeing that you are busy? Otherwise, we would have looked for you earlier." Zhang Gaoming said.
He actually had nothing to say.
That is, he does not want Lingzhou University of Technology to participate. All he wants is the handheld imaging scanner produced by Lingzhou University of Technology.
This thing is powerful enough.
In just a short time, the detection of the ice layer at a depth of two kilometers was completed, instead of having to collect ice samples and send them to the laboratory for testing like they did.
As for not wanting Lingzhou University of Technology to participate, it’s just for the sake of fame.
"That's true! You don't want our Lingzhou Institute of Technology to participate! You're worried that we will steal the name of your Lingzhou Institute of Optoelectronics." Xu Zhengping said bluntly, "Lao Zhang! Don't worry, even if we find traces of life, , and won’t force this name, because we at Lingzhou University of Technology don’t need these to prove it.”
"Old Xu! Daqi! This is what you said. Don't regret it if you find out later." Zhang Gaoming said.
"How could you regret it? You are overthinking." Xu Zhengping said.
At this moment, Su Zhe's voice sounded on the public channel, "Big discovery, a broken ribonucleotide was discovered."
"I also discovered that there are ribonucleotide fragments and protein fragments." Fan Xiaoming shouted.
Several people first gathered around Su Zhe and looked at the broken ribonucleotides that Su Zhe found.
Then they gathered around Fan Xiaoming.
After reading it, Zhang Gaoming exclaimed, "It's solid! There must have been life on the moon in the past, and there was almost the same carbon-based life as our earth."
"Yes! The genetic material and protein fragments are enough to prove that life existed on the moon." Xu Zhengping said.
"Let me just say it! Our speculation is correct, there must be life on the moon." Fan Xiaoming said.
"Continue! Continue! Maybe we can find frozen lives." Zhang Gaoming said.
After a while, the group of people arrived at the bottom of the ice cave, which is at a depth of 2.8 kilometers.
There are many humanoid robots and engineering machinery at the bottom, and they are busy mining the ice.
Along the way, we discovered a lot of genetic material and various proteins, and even a variety of sugars.
Judging from the results of these detections, it is certain that life existed in this area of the ice in the past.
But they have never discovered the existence of life, such as single cells such as bacteria and cyanobacteria. Even if they have discovered viruses, it will be good.
But nothing was found.
Xu Zhengping looked at the two busy figures of Su Zhe and Fan Xiaoming and said, "Two of you, it's almost time. Forget it if you can't find them. It will be dinner time in a while, and we should go back."
Genetic material, proteins, and sugars have been found in the ice. These are enough to prove that there was life on the moon in the past. It doesn't matter whether we can find samples of life or not.
As for the later exploration, let other personnel complete it.
They're going back to the moon base.
"Don't rush back now, we'll keep searching, maybe we'll find it." Fan Xiaoming said while busy exploring.
"It's six o'clock in the afternoon Beijing time. I just need to get back to the moon base before going to bed at night." Su Zhe said.
"Okay! Let's continue the detection for a while." Xu Zhengping said, "Lao Zhang! How are you doing with biological control over there? Don't let bacteria and viruses from outside the earth return to the earth beforehand. A devastating blow to humanity."
The bacteria and viruses that exist on the earth have co-evolved with humans and have lived in the same environment for tens of millions of years.
Not to mention extraterrestrial bacteria and viruses, even the ancient bacteria and viruses that exist in the ice or frozen soil of the Earth's North and South Poles are not necessarily fatal threats to humans.
He did not want to see a moment of human negligence leading to a large number of human deaths.
"Old Xu! Are you confused? Today is different from the past. Even if we bring extraterrestrial bacteria and viruses back to the earth, with the gadget developed by Professor Ning Changshengning, no bacteria or viruses can escape. , will all be wiped out." Zhang Gaoming said.
They have always attached great importance to biological prevention.
Regardless of whether they have the thing developed by Professor Ning Changshengning or not, they will strictly abide by the regulations on biological prevention.
"That's right. How could I forget this incident?" Xu Zhengping said, "But we still have to pay attention to it."
The two of them chatted and even left in the middle of the trip.
When the time came to 9:30 pm, it seemed that Su Zhe and Fan Xiaoming had nothing left to detect.
At this time, the depth of the ice cave has reached 2.95 kilometers, and another fifty meters can penetrate the ice.
At this time, Su Zhe and Fan Xiaoming were following the construction machinery. They were exploring a section of the ice cave while they were mining it.
"It's almost time, we should go back to the moon base." Su Zhe said.
"Well! I'm a little hungry, it's time to go back." Fan Xiaoming said.
Just as the two were discussing going back, the red light on the handheld imaging scanner in Fan Xiaoming's hand kept flashing.
Su Zhe and Fan Xiaoming looked at the screen of the handheld imaging scanner with surprised faces. They saw an incredible scene.
Xu Zhengping and Zhang Gaoming, who were chatting not far away, noticed the difference here and flew over immediately.
The two of them stood around and watched for a long time. Zhang Gaoming exclaimed, "Cyanobacteria! This is cyanobacteria! How could cyanobacteria be found in the ice? It shouldn't be!"
"Lao Zhang! How are you so sure it's cyanobacteria? Can't it be other single-celled prokaryotes?" Xu Zhengping looked at the screen of the handheld imaging scanner and was surprised. He really found single-celled prokaryotes in the ice. , and still so complete.
"I don't understand what you are doing in aerospace." Zhang Gaoming looked at Su Zhe and Fang Xiaoming and asked, "You two, what do you think this single-celled prokaryotic organism is?"
The reason why I didn't agree with Xu Zhengping was because Xu Zhengping majored in aerospace and didn't know much about biology.
You know, after discovering this ice layer, he did his homework.
"Well! I just compared the single-celled prokaryotes discovered with those found on the earth. What we found is indeed cyanobacteria. There are only slight differences from the cyanobacteria found on the earth, but we can be sure This is cyanobacteria." Fan Xiaoming said with certainty.
He was also shocked when he discovered the blue algae.
He was about to give up, but he didn't find it and it was so complete.
"What! You compared it with the cyanobacteria found on the earth. How...how did you do it?" Zhang Gaoming's face was full of surprise.
"Old Gao! Is this strange?" Xu Zhengping said nonchalantly, "Our Lingzhou University of Technology has built a corresponding database, and coupled with a supercomputer equipped with artificial intelligence, it is not difficult to make such a comparison!"
"You...you..." Zhang Gaoming's face was full of envy, "Can our Lingzhou Optoelectronics Research Institute have such a service?"
"Yes! As long as you are willing to pay the service fee." Xu Zhengping said with some pride.
"Hand it over! Hand it over! We will definitely hand it over!" Zhang Gaoming said firmly.
While the two were discussing the service fee, Su Zhe and Fan Xiaoming continued to investigate.
As the depth increased, the two discovered more and more single-cell prokaryotes and a variety of viruses.
Among them, many single-cell prokaryotes and viruses have complete structures.
