Science and Technology Library

Chen Mo took two test tubes of blue liquid from Mo Nu and handed them to Zhao Min and Xiao Yu.

"what is this?"

The two looked at the liquid in Chen Mo's hands strangely, it looked like some kind of oral liquid, and there was nothing special about it.

"A radiation-preventing drug that prevents the human body from gene mutations that may occur due to space radiation." Chen Mo explained.

After all, there is radiation in space, and long-term activities in space will cause genetic mutations, which are not good for the human body.In order to reduce this problem, Chen Mo found this kind of anti-radiation medicine from the science and technology library.

The medicinal effect of the medicine is one week, and it will be produced by Haixing Company in the future, and it will be used by astronauts and workers in high-radiation positions.

Zhao Min and Xiao Yu didn't think much, took the potion and drank it.

This is the first time for Xiao Yu and Zhao Min to go into space, so they are somewhat nervous, but fortunately Chen Mo is by his side, so they feel a little bit more secure.

"Let's go."

Chen Mo led the two of them towards the Goddess.Under the attention of the ground personnel, a strong wind blew up on the airport, and the Goddess slowly floated into the air and disappeared into the distant sky.

In the distant and unknown depths of the universe, a bright spot shuttles from far to near, flying fast.

The spaceship slowly approached, revealing its true colors.

The ferocious spaceship, with its edges and corners, is covered with various weapons.

In the cabin of the spaceship, there are sleeping pink creatures, about three meters high, with a lizard-like head, eyes closed, synthetic finger-long slits, bulging, no ears, and finger-long tentacles on the top of the head .

In the transparent dormant chamber, you can see the pink body of the unknown creature. The skin is as soft as an octopus, covered with strange patterns, the legs are hideous scales, and there is a blood-red tail wrapped around the back, about two meters long. , covered with various spikes.

Inside the cabin, a strange and sharp sound suddenly sounded, and it was translated.

"Redtail ephemeris, at 204756:21:74 on 42/64/89, the fugitive 20981 spacecraft has entered the Milky Way, the 5142nd destination, the Milky Way Orion, is expected to arrive in 5 years, no habitable stars have been found... "

Just after the report was completed, a sharp and piercing alarm sounded, and in an instant, all the dormancy compartments in the spacecraft control room were opened, and the sleeping pink creature suddenly opened its eyes, and panic appeared in the red pupils.

"The highest level of alert, the highest level of alert, a meteorite stream appears at coordinates A5247, S1547, and X24567. After 5 seconds of impact, the weapon system is activated."

"Chirp..."

The tentacles on the head of the red-tailed creature swayed, and weird sound waves came out from its mouth.

The entire control room panicked.

The spacecraft weapon system has been turned on, all aimed in the direction of the meteorite.

boom! ! !

One after another particle beams flew towards the meteorite flow, and the meteorite that was hit exploded in an instant, turning into smaller fragments and flying in all directions.

"Alarm, alert, hull damage."

"Alarm, the hull is damaged, please leave the spaceship immediately, please leave the spaceship immediately."

The red-tailed creature heard the alarm, with despair in its eyes.

boom!

The impact of the large meteorite instantly exploded the spaceship that had wandered in the universe for an unknown number of years, and countless fragments and wreckage of the spaceship shot in all directions.

The largest fragments, along with the meteor shower, are heading towards Orion's lasing.

On the spiral arm of Orion in the flying direction of the fragments, the sun still radiates eternal light, and the azure earth is still slowly spinning forward.

"it's beautiful."

On the Goddess, Xiao Yu leaned against the window, looking at the blue planet outside the window, with an excited face.Beside her is Zhao Min with a complicated expression.

Like two children who have never seen the world, the two kept their eyes on the earth.

The blue fluorescent planet in front of them is the planet they live in.No living things can be seen, and their huge corporate headquarters is too small to be seen at all.

How big is the vision and how broad is the mind.

At this moment, they really felt that human beings are smaller than dust in the universe. To the eternal universe, they are just fleeting passers-by.

People with unstable minds may lose their fighting spirit if they experience this feeling of insignificance.

Seeing Xiao Yu who was only excited, Zhao Min felt a little envious.It's good to have someone take care of you, don't think too much, sometimes it's good.

Chen Mo next to him looked calm.

She only now understands that Chen Mo has the fighting spirit to face the challenge of the universe.

I'm afraid this man won't be reconciled to a bacteria-like disappearance in the long river of the universe.

Chen Mo seemed to see Zhao Min's thoughts, smiled and stretched out his hand to pat her on the back, and also touched Xiao Yu's head: "Is it beautiful? Is the Galaxy over there or the earth?"

"Then do you think Miss Mo is prettier, or sister Zhao Min?" Xiao Yu asked jokingly.

Hearing this question, Zhao Min almost burst out laughing, this rhetorical question is really interesting.

"Well, each has its own merits, and they all look good." Chen Mo said with a dry smile.

"Tell me, are there really other creatures and alien civilizations in this universe?" Xiao Yu looked at the earth outside the window with some emotion after recovering.

"Let the great scientist answer you."

Both Zhao Min and Xiao Yu looked at Chen Mo, waiting for his answer.

"This question is similar to deep-sea bacteria. The bacteria living in the small pit deep in the trench ask if there are other bacteria outside." Chen Mo said with emotion: "There must be, but they are limited to the deep sea."

"But isn't there a Fermi paradox? Assuming there are aliens, millions of years before our development, space travel must have discovered us. But we have not discovered the appearance of aliens, and we have not found that aliens are real. Evidence of existence, does it mean that aliens do not exist?"

"Okay, I even know these theories." Chen Mo laughed.

"I just heard about it." Xiao Yu said.

"This paradox is a paradox. In fact, in Liu Cixin's "Three-Body Problem", a possible explanation for the Fermi Paradox is based on the law of the dark forest. The discovery of alien civilizations, so as not to invite the cleanup of higher civilizations.

But it is only a possibility, not all civilizations will hide from each other, so humans launched Voyager 1.

There are many other possibilities to explain the Fermi paradox.

Just like the deep-sea bacteria I mentioned just now, the Fermi paradox is equivalent to the deep-sea bacteria asking, are there other creatures outside?If so, why haven't they been discovered yet?Or be found by them as evidence of our existence.

They didn't find us, so we don't exist?

In fact, there is a problem of finding the time span here.A few million years is very long for human beings, but very short for the universe.

Millions of years ago, we were just a puddle of liquid.Assuming that the bacteria on the seabed can only live for two days, how many generations will it have to pass on before it can be discovered by us?

Perhaps decades later, during a deep-sea scientific exploration, humans will discover that deep-sea bacterial colony, and then a few decades later, they will discover other second and third bacterial colonies?When those colonies were found, it was sooner or later.

The same problem is also applicable to us. Suppose we are a certain colony in the deep sea of ​​the universe, and the aliens have not found us yet in their exploration journey?After all, space travel is much more dangerous than deep sea exploration, and much wider than the sea.

Of course, you can also assume that the creatures in the universe appeared at the same time. We are the fastest generation of civilizations. After a few million years, we will explore the universe and discover other civilizations. No matter what the result is, it is scientifically inferred that alien life exists. .

But in the universe, what is the probability that we are the first generation of cosmic civilization?This probability is equivalent to that all creatures on the earth think they are the first generation of civilization.The probability exists, but this probability is estimated to be lower than the probability of the penguin game's lottery. "

Hearing the last ridicule, Xiao Yu and Zhao Min couldn't help laughing.

"I think it should be a little higher than the probability of the penguin game's lottery draw." Zhao Min laughed jokingly.

"It's so complicated. Fortunately, I'm relatively stupid, so I don't have to think so much." Xiao Yu said.

She generally understood the meaning of Chen Mo's explanation, as for thinking about it, it was out of her scope of consideration.

"Are you afraid that one day aliens will find our 'colonies' and capture you as a specimen for research like humans do?" Zhao Min asked.

"Then I will aspire to be the one who infects them with deadly superbugs."

"If discovered by aliens, won't they directly exterminate us as described by the three-body problem?" Xiao Yu asked curiously.

"Maybe, but maybe not, the same level of civilization, or when the civilization levels of two species are close, the law of the dark forest may apply. For example, in the age of great exploration, the Indians in America were massacred.

But for civilizations at the same level, or civilizations at a level similar to ours, the probability of exploring the universe to us is too small, and the time span and distance span are too long.A civilization at the same level as ours, unless it finds a habitat like Trisolaris, it is impossible to use the whole family to exterminate us.

Civilizations that are much higher than our level of civilization have discovered us, such as going to Africa for expedition research and discovering a new species of ants in the rainforest. Will we burn the ant nest?Obviously not.Catch a few at most to study and study, or to watch.

If our human intelligence and civilization have not reached their level and will not threaten their interests, and our living environment is of no value to them, the law of the dark forest may become invalid.If we are interested in them, then you can refer to the small animals in the zoo. "

Chen Mo looked at the depths of the cosmic starry sky and said quietly.

The law of the jungle is applicable to any civilization, that is the nature of the universe,

Chapter 637 Space Center Expansion Completed

The endless scenery is on the dangerous peak.

This is the true feeling of Xiao Yu and Zhao Min at this moment.

Looking at the earth from the perspective of space, everything is so small, which makes people fascinated. Looking into the depths of the vast galaxy, I feel so small.

Talked to Chen Mo about some speculations about aliens, and the two stopped discussing this issue.

Asking about aliens is just pure curiosity.

But they don't know that in the near future, the earth will actually see evidence of the existence of aliens.

"You two have a 'space kiss' from an altitude of 400 kilometers."

Zhao Min held the camera, fixed the magnetic shoes on the space capsule, and looked at the two people in front of him flirtatiously.

Space tourism is purely for traveling and experiencing space in person, so the tools that travel should have are available on the Goddess, and taking pictures as souvenirs is naturally essential.

Hearing Zhao Min's 'photographer' request, Xiao Yumei's eyes turned into Chuyue and looked at Chen Mo.

"Come."

Chen Mo was not hypocritical, he hugged Xiao Yu and kissed her.

"The angle is a little bit right, yes, it is like this to keep the floating angle. Perfect, a space kiss at a speed of 7.9 kilometers per second. I feel that these photos I took can win awards in the photography competition."

Zhao Min directed the two of them, pressed the shutter of the camera, and did not forget to tease them.

After the two let go, Xiao Yu licked her pink head and felt Chen Mo's residual breath. She was extremely happy. This was the most romantic thing she did after she and Chen Mo got married.

Although the process of going to space was a bit hard, and the body is not very comfortable in space now, it is all worth it.

"I'll give you a little bonus today." Xiao Yu looked at Chen Mo with a smile: "Mr. Mo, come here, let's take an intimate photo with Brother Mo."

"Oh." Mo Nu didn't hesitate, and floated towards the two of them.

After the three of them finished shooting, Xiao Yu asked the robot on the Goddess to hold the camera and take some group photos of the four of them, and then it was Chen Mo's turn to be a professional photographer to take sister photos of the three girls.

They were all happy, and Chen Mo never tired of it.

This can be regarded as a space tour, mainly for relaxation, without doing research experiments, just letting Xiao Yu and Zhao Min feel the magic of space.

After taking the photos, the two women went to the telescope to observe the starry sky in the depths of the universe, and intuitively feel the mysterious charm of the depths of the universe.

This space trip is not monotonous. In addition to some stargazing equipment, there are also some small space experiments. Two women will do it to feel the magic of the physical properties of weightlessness.

The space journey lasted for three days, and it was not until the fourth day that the Goddess slowly slowed down and returned to Earth.

A month passed by in a hurry.

Phoenix Mountains.

Looking at the huge hangar in front of him, Luo Nan admired it.

This is the power of the China Construction Third Bureau mobilizing the whole group. With the assistance of the most advanced engineering technology of the Marching Army Ant Group, it took three shifts and more than four months to build the successful hangar.

This is the second hangar of the Flying Ant Space Center, and it is currently the largest hangar in the world.

The hangar combines aircraft assembly and maintenance in one, with a length of 1257 meters, a width of 274 meters, and a height of 45 meters, creating many world records, and the consumption of steel cannot be counted.

The hangar is a single-layer steel structure. The steel is made of special steel produced by the special steel formula provided by the Army Ant Group. After testing, the yield and strength of that steel are three times that of the existing special steel.

The entire hangar is supported on 32 huge load-bearing columns. All the load-bearing steel structures of the hangar adopt seamless welding technology, and the welding joints reach 100%, so that the steel forms a whole. Withstand the weight of more than 2800 tons of equipment.

When the Army Ant Group called them the design drawings of the hangar, the designers and construction personnel of the Third Construction Bureau among them were all shocked by this bold design.

In order to study the design drawings and construction plans, they printed out more than 4000 design drawings.

I can't think of any team in the world that can design such a huge hangar structure, and the steel structure of each part, and even the detailed data that is generally not paid much attention to, are detailed to two decimal places, and all data are complete. complete.

This is the most shocking project since they have undertaken many world-class projects, and they have also faced and felt the terrifying foresight and strategic ambition of the Army Ant Group.

What this hangar will produce is definitely not an ordinary aircraft.

In addition, what shocked him even more was that the construction of the base of 3 mu was actually completed on time in just four months.

At the beginning, the Army Ant Group gave them the design drawings of the base and requested that the construction be completed within four months, and the construction cost could be four times the normal construction cost.But when they saw the 4-acre base, as well as the huge and complex buildings and this hangar, they all thought that the army ant group was playing tricks on them.
