Year after year
The whole fleet has entered the open space. Kunlun mountain successfully used several large gravitational fluctuations to accelerate the fleet to the rated speed and enter the normal navigation.
Its goal is... 187j3x2!
Although Zhang Yuan is the chief captain of the Kunlun Mountain fleet, he also has his own hibernation time. Hibernate about every five years for two years, more than half of the time. But compared with ordinary people, he woke up much more frequently and aged faster, which is the price of being a captain.
The daily work is not too busy. No matter how big Kunlun Mountain is, it is only a spaceship. Without massive resources as support, it is impossible to engage in any major project. Everyone's general work, that is, routine maintenance of the spacecraft, doing simple research, or designing some new machinery.
The materials in the laboratory are enough. Anyway, almost all resources can be classified, recycled and reused, and all they consume is energy.
There are many talented people in the spaceship. It doesn't mean that everything has to be arranged by Zhang Yuanlai himself. If there were no special events, Zhang Yuan would be at leisure.
In this way, it has been stable for 39 years
On this day, Xu Yuanyuan, a graduate student in space botany, and several colleagues are cultivating a new generation of space mutant plants in the radiation area of the observatory.
Although space travel is boring most of the time, there are some new things occasionally. For example, when crossing the Kuiper belt, people observed several large comets, the nearest distance being about 800000 kilometers.
Because no large planet has been formed near the Kuiper belt, which is extremely weakly affected by stars and has not experienced various complex astronomical phenomena, most of its composition basically represents the original components in the early stage of the formation of the planetary system, which is of great significance for human beings to understand the origin of stars.
Scientists once wanted to capture these meteorites, but because the speed of the whole fleet was too fast, the whole capture operation failed
This reliable operation also made the whole ship fly like chickens and dogs, and many researchers were lost because of this failure.
Later, about 0.2 light-years away from the star, the whole fleet encountered a strange ion wind. Such ion winds have been encountered at the periphery of the solar system. I don't know why
Results after exploring for a long time, there is still no scientific model that can convince everyone.
Since then, there has been no major event. The material in interstellar space is too sparse. In addition to cosmic radiation, it is a great luck to sail in this place for millions of years and encounter a meteorite as big as your thumb.
"I'm going to hibernate in five months. I always feel that I've accomplished nothing in recent years."
"You stay on the planet and don't do the same work..." several girls wear spacesuits and chat casually. They collect soybean sized seeds one by one and place them in Petri dishes.
"Hey, can favorable mutations occur in seeds?"
"It's hard to say... If only we could find all the codes of genetic material, we don't need to hit luck like now."
"Too stupid to understand."
DNA is an extremely complex substance for human beings. Every piece of DNA contains a large amount of information. This mass is a real mass. The sequence of base pairs is only the most preliminary one-dimensional information, as well as more complex two-dimensional information and even spatial three-dimensional information!
Therefore, up to now, mankind has not completely decoded the real mystery of genetic material.
Cultivating space mutant plants is a very boring and happy thing. Its principle is very simple. It makes plant seeds mutate to a certain extent by using the radiation in space.
The vast majority of mutations are harmful mutations, resulting in the complete failure of seeds to survive.
But a small number of mutations are beneficial and produce a wonderful response. For example, Portuguese grass, a kind of algae widely used to purify the air and very delicious; Antimercia, a variety of banana, can produce a large amount of ethylene; Small hemp grass, a variety of cotton, but the yield is twice that of cotton
Every time we cultivate a brand-new seed, it's like touching a lottery ticket, with an inexplicable sense of expectation. Even if the vast majority will not win the prize, the moment of winning the prize is completely entering the peak of life!
Because of the emergence of all kinds of beneficial mutant plants, people's life is also better.
These plants provide chemical raw materials for industrial production, and some are food for humans and animals. They are also purifiers of the air environment, which is not generally important to humans.
After placing all the seeds, Xu Yuanyuan suddenly felt something sweeping his eyes.
The whole world turned into a crystal red at this moment!
"Ah!"
She gave a low shriek.
This feeling was like being swept into her eyes by a laser pen, which made her eyes sour and painful, and her tears couldn't stop coming out.
She covered her eyes, and the other looked around suspiciously.
"What's the matter with you?"
"I don't know..."
The starry sky was so dark that nothing could be observed except the light of the spacesuit.
She didn't know whether it was her own illusion or something else, but the redness and swelling of her eyes were real, and there was still a tingling feeling of being burned.
Xu Yuanyuan hurried back to the Mothership and went to the hospital for examination. The doctor who helped her was surprised when he heard the specific reason. Then he dared not delay and reported the discovery to the relevant government departments
"What, a girl is suspected to have been hit in the eye by a laser from the outside?!"
Zhang Yuan was also surprised when he heard about it. He hurried to the hospital to visit the girl in person.
The doctor in the hospital replied, "it's just that the eyeballs are slightly congested. It should be all right to rest for a while. There's no need to replace any bionic eyeballs."
"OK, thank you. If the nearby frigate misoperates, the relevant compensation and apology will be approved immediately."
But the whole incident sounds incredible!
At first, Zhang Yuan thought it was the frigate's communication laser that accidentally hit people. As a result, a few minutes later, all the surrounding frigates sent information, and there was no error or misoperation.
"Report to the captain, Eagle Falcon 1. There is no error. There is no misfired communication laser."
"Report to the captain, Falcon 2 has checked correctly."
……
Finally, the military also sent an investigation report: "it is confirmed for the second time that there is no error in the inspection, and there is no misfired communication laser."
In order to prevent large-scale exposure of communication waves, the connection between the carrier and the frigate depends on directional laser. Under normal conditions, the frequency is about once a minute.
Zhang Yuan took a deep breath. He soon realized some other possibilities
"If it is not the result of the misoperation of the frigate, then... Is there any other possibility?"
An... Alien civilization!
Near here, there may be an alien civilization that is using a small frequency laser to detect the outside world!
Things soon became serious.
He comforted a few words, hurried back to his captain's room and sent out an emergency notice. The reason why such information can be inferred is that the Kunlun Mountain fleet often detects the outside world through low-frequency lasers.
This starry sky is too dark. The nearest star is 2 light-years away. There are so few photons in space that it is almost dark.
This darkness makes conventional observation equipment completely unable to observe the surrounding environment. Therefore, the best exploration method is to use microwave or laser!
Using the microwave radar with huge power, the effect is very good, and everything around can be illuminated soon. But this high-power radar will directly expose its position, just like a huge light bulb in the Dark Universe. It can't be unknown.
Therefore, the use of probe laser has become a very good choice.
The power of this kind of probe laser is not high and can be emitted continuously. When the laser touches a relatively smooth object, it will produce a series of diffuse reflection echoes. By analyzing the data of these diffuse echoes, we can get the specific shape and position of the object
When thinking of this possibility, Zhang Yuan was excited and worried. He issued an order at the first time: "attention, all spacecraft, please note that there may be unknown alien civilization around. Use the detection laser to detect!"
