Chapter 636: Fermi Paradox and Deep Sea Bacteria Theory

The United States has obtained the artificial intelligence it wants, and the disputes with the island countries have subsided and returned to normal.

The turmoil in the world is fading.

The island nation is still fighting against Russia across the air, but it is not as intense at the beginning. The United States has taken a lot less action and seems to be fully preparing for the next election issue.

All three countries have artificial intelligence, and they all feel the horror of artificial intelligence. They have not publicized it, and want to keep a low profile as much as possible.

The island country and the United States still maintain the original relationship, and in order to fight against Russia, a military exercise was specially held. It seems that the contradiction some time ago has never happened.

Only the parties know that the two sides have already been at odds with each other.

Now events are slowly subsiding, and the world is at peace again.

Flying Ant Space Center.

The Goddess is ready.

In the past two months of training, Xiao Yu and Zhao Min's aerospace training has been completed, and they have suffered a lot.

Today is the day of space travel.

At this time, Xiao Yu and Zhao Min were already wearing space suits, their bodies were covered, only one head was exposed.

"Drink this."

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

"what is this?"

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

"A radiation-preventive agent to prevent genetic mutations that may occur in the human body due to space radiation," Chen Mo explained.

After all, there is radiation in space. Long-term activity in space will cause genetic mutation, which is not good for the human body. In order to reduce this problem, Chen Mo found this radiation preventive medicine from the science and technology library.

The efficacy of the drug is one week, and it will be produced by the Starfish Company for the use of astronauts and staff in high-radiation positions.

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

This is the first time Xiaoyu and Zhao Min have gone into space.

Somewhat nervous, but fortunately Chen Mo is by his side, so he has some sense of security.

"Let's go."

Chen Mo took the two of them and headed towards the Goddess. Under the attention of the ground personnel, strong winds rolled up at the airport, and the Goddess slowly floated into the air and disappeared into the distant sky.

In the far and unknown depths of the universe, a bright spot travels from far to near, traveling fast and fast.

The spacecraft approached slowly, revealing its true colors.

The ferocious spaceship, the edges and corners of the surface, are covered with various weapons.

In the cabin of the spaceship, there are sleeping pink creatures, about three meters high, with heads like lizards, closed eyes, synthetic finger-long slits, bulging protrusions, no ears, and finger-long antennae on top of their heads. .

In the transparent dormant chamber, you can see the pink body of the unknown creature, the skin is as tender as an octopus, covered with peculiar patterns, the legs are ferocious scales, and there is a blood-red tail behind it, about two meters long. , covered with various spikes.

Inside the cabin, a strange and sharp voice suddenly sounded, which was translated.

"Akatail Ephemeris, at 42:64:89 on 21/74/204756, 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 star has been found... "

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

"The highest level of alert, the highest level of alert, a meteorite flow appears at coordinates a5247, s1547, x24567, and after 5 seconds, it hits and the weapon system is activated."

"chirp chirp..."

The tentacles on the head of the red-tailed creature swayed, and strange sound waves were emitted from its mouth.

The entire control room panicked.

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

boom! ! !

One after another particle beam flew towards the meteorite stream, and the hit meteorite exploded instantly, turning into smaller fragments and flying in all directions.

"Alarm, alarm, hull damage."

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

When the red-tailed creature heard the alarm, there was despair in his eyes.

boom!

The impact of the large meteorite exploded the spaceship that had been wandering in the universe for many years, and countless fragments and shipwrecks shot in all directions.

The largest of these fragments, along with the meteorite shower, is blasting away towards the constellation Orion.

On the Orion spiral arm in the direction of the debris flight, the sun still exudes an eternal light, and the blue earth is still spinning forward.

"it's beautiful."

On the Goddess, Xiao Yu crouched by the window, looking at the blue planet outside the window, his little face was excited. Next to her is Zhao Min, with a complicated expression.

The two were like two children who had never seen the world, their eyes fixed on the earth.

The blue fluorescent planet in front of them is the planet they live in. No creatures could be seen, their huge corporate headquarters was so tiny that it was impossible to see at all.

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

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

People who are mentally unstable, who experience this small feeling firsthand, may directly lose their fighting spirit.

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

Chen Mo next to him looked calm.

She only now understands that Chen Mo is facing the fighting spirit to challenge the universe.

I'm afraid this man will not be willing to disappear into the universe like a bacterium.

Chen Mo seemed to see Zhao Min's thoughts, smiled and reached out and patted her back, and also touched Xiaoyu's head: "Is it beautiful? Is the galaxy over there beautiful, or the earth?"

"Then do you think Mo Nv is good-looking, or Zhao Min is good-looking?" 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 looks good." Chen Mo said with a dry smile.

"Tell me, is there really other creatures, alien civilizations, in this universe?" Xiaoyu looked at the earth outside the window with some emotion after regaining his senses.

"Let the great scientists answer you."

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

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

"But isn't there a Fermi paradox? Assuming that there are aliens, millions of years before our development, cosmic travel must have discovered us. But we have not found that aliens appear, nor have we found that aliens are real Evidence of existence, is there no aliens?"

"Okay, even these theories are known." Chen Mo smiled.

"Just heard of 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 main idea is that alien civilizations deliberately hide themselves from others. Alien civilizations are discovered, so as not to attract more advanced civilizations to clean up.

But it is only a possibility, not all civilizations will hide from each other, and humans have launched Voyager 1 to the outside world.

There are many possible explanations for 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 out there? If so, why haven't they been discovered yet? Or be discovered by them as evidence of our existence.

They didn't discover us, did we just not exist?

Actually there is a problem of discovery time span here. Millions of years are long for humans, but short for the universe.

Millions of years ago, we were just a puddle of liquid. Assuming that the bacteria on the seafloor can only live for two days, how many generations will it have to be passed down until the day we discover it?

Maybe a few decades later, a deep-sea scientific exploration, human beings will discover that deep-sea colony, and then in a few decades, they will find another second colony, a third colony? Those colonies were found sooner or later.

The same problem applies to us. Suppose we are a colony in the deep sea of ​​the universe, and the alien's exploration journey has not yet found us? After all, space travel is far more dangerous than deep-sea exploration, and far wider than the ocean.

Of course, you can also assume that the creatures in the universe appeared at the same time. We are the fastest generation of civilization. After a few million years, we will discover other civilizations in the universe. No matter what the result is, it is scientific inference that extraterrestrial 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 of all creatures on earth thinking that they are the first generation of civilization. The probability exists, but this probability is estimated to be lower than the lottery probability of the Penguin game. "

Hearing the last joke, Xiao Yu and Zhao Min couldn't help but laugh.

"I think there should be a higher probability than the Penguin game lottery draw." Zhao Min joked.

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

She roughly understood the meaning of Chen Mo's explanation, and as for careful consideration, it was not within her scope of consideration.

"Are you afraid that one day aliens will discover our 'colony' and take you as a specimen for research just like humans grab specimens?" Zhao Min asked.

"Then I'm going to aspire to be the superbug that infects them."

"If discovered by aliens, wouldn't it kill us directly as described by the three-body?" Xiao Yu asked curiously.

"Maybe, but it may not. When civilizations of the same level, or two species are close to each other, the law of the dark forest may apply. For example, in the era of great voyages, the Indians in the Americas were slaughtered and exterminated.

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

Civilizations far higher than our civilization level discovered us, such as exploring and researching in Africa, and discovering a new species of ants in the rainforest. Will we burn the ant nest with a fire? Obviously not. Catch a few at most for research or viewing.

If the level of our human wisdom and civilization evolution has not reached their level, will not threaten their interests, and our living environment has no value to them, the law of the dark forest may fail. 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 strong eat the weak, no matter what kind of civilization, it is applicable, that is the essence of the universe,
