Chapter 297: Chapter 298 The Paradox of Civilization (Part 1)
"Why are you a little strange today?"
"Is I strange?"
Huo Gu's action of eating obviously paused for a moment, and then recovered. He responded in a salty response to cover up his gaffe, and how could this behavior escape Karen's eyes?
Karenna sighed with an expression of 'Don't hide it, I've seen through it for a long time'.
"Every time you eat quickly, you are always in a hurry to go back to the library to read books, but today it's not like this. For a learning monster, doesn't this make a point?"
Huo Gu turned his head aside, looked through the window of the restaurant, and scanned the pedestrians outside back and forth, with his eyes as sharp as a falcon.
Karenna saw Huo Gu turn his head and didn't think much about it. She just thought that she was poked in the center and lost her temper.
"I want to slow down the pace of life, but it's you. Don't you want to explain it to me?"
"Well, what does it mean?"
When asked by Huo Gu so suddenly, Karenna was slightly stunned and thought about it carefully. With a hammer in the palm of her hand, she seemed to figure out something and suddenly looked at Huo Gu.
"Oh, you are expecting me to answer your last question, right? That's really a scary question.
"Do you understand?"
Huo Gu's action was stopped again, but this time it was different from before. It was surprised that Karenna could understand it. According to the impression given to Karenna's incident, it was not very easy to learn, and his talent was not smart. She was not too self-motivated, and it was at most medium in the whole group.
Such a person actually claimed that he had penetrated the problem from the two tips, which was very suspicious.
"Of course."
Karenna was straight and proud, with her waist crossed, as if she was full of victory.
She cleared her throat and began to explain the inference information she had learned from the two tips given by Huo Gu that day.
"Today's empire has been able to make a detector of a certain quality reach sublight speed, and the diameter of the river system we are in is about 180,000 to 200,000 light years. The maximum value can be taken to get the answer that it takes 200,000 years for sub-light detectors to cross the whole river system."
"That is to say, assuming that there are other civilizations in the river system, it only needs to reach the current height of the empire 200,000 years before the empire and launch a detector. The empire should have been in contact with them now."
"This is only 200,000 years earlier than the empire. If it is an alien civilization 10 million years earlier, the Selin people should have known their existence or established communication when they first came into contact with the universe in the era of great powers, because these civilizations have already occupied the whole river system."
"However, the actual situation is exactly the opposite. Except for the amoeba, an alien civilization of this stellar system, we have never been in contact with any aliens. The whole universe is very quiet."
Yes, this is the famous 'Femi paradox' on earth. One day in 1951, Fermi proposed - 'Where are they?' A series of scientific derivation from this problem.
Now, in this unknown time, in a corner of the universe, far away from the Earth, Huo Gu asked that question again.
"Yes, so why is that?"
The Selins did not find this scientific question. Although they were aware of the concept of 'aliens', they did not realize Fermi's paradox. Therefore, when Hogu gave a hint again, Karenna did not immediately give Hogu an answer.
Everything she knows now is only based on the two tips given by Huo Gu.
When discussing academic issues, Karenna gradually put away her usual play and became more like a scholar.
"The question you ask can lead to three explanations. First, we, the Serin and Amoebas, were the first civilizations in the early days of this river system, so there has been no flood of regular signals in the whole river system."
"Second, regular signals exist, but because our technology gap is too big,
Even the readable regular signal is mistaken for such a natural phenomenon and ignore it."Third, those civilizations have perished without exception, and they have not reached the current height of the empire. Otherwise, according to the desire to continue the civilization itself, even if they encounter an inevitable crisis of extinction, they must at least leave the evidence to prove the existence of their own civilization."
Later, Karenna explained why the detector was used as a tombstone.
"The detector is an excellent tombstone choice, because it will diffuse the information, and it is easy to be known by other civilizations about the information of the destroyed civilizations, and accelerate to the sub-light speed. The ruler shrinkage effect will change its appearance to extend the life of the detector, multiplying tens of thousands or even hundreds of millions of times, and cross the whole river system. The normal time is over. More than 100,000 years, but it may only have been a few years for the detector.
"...Gu, what you meant at the beginning is imminent. Do you mean this?"
After explaining her understanding, Karenna looked at Huo Gu with complicated eyes, because this bad guy's different thinking made her realize a terrible thing.
At the same time, there was unparalleled admiration in my heart, but soon, Karenna's admiration was dissipated because of Huo Gu's next words...
"You can think of it that surprises me a little. After all, I always think you are a fool who doesn't study much."
I ignored Karenna, who looked a little stiff, and Huo Gu continued to say, explaining why he was inclined to the third.
"The first one is too arrogant. The river system is as old as the universe. Ten billion years of history, whether it is the Selin people or Amoeba, is just a drop in the vast sea. It is said that the first batch is simply a grisance."
"The second can only explain those advanced civilizations that have existed for a long time, but those civilizations that are 200,000 or 300,000 years old, such as examples, are not included, so these civilizations can only be explained by the third one."
Horgu paused and put down the cutlery in his hand, because it was finished.
"There is an unknown horror that erases these civilizations, and you have a little inference that you are wrong."
"What did you say wrong?"
Karenna looked thoughtful. She should have missed nothing right. Where was the mistake?
Then, Huo Gu told her where it was wrong and why it was wrong.
"Why do you have to assume subjectively that there will be no civilization that has reached the height of empire? Can't Amoeba achieve sub-light speed? The two known civilizations have reached this level. Can it be assumed that it is a common phenomenon for civilizations to reach sublight speed in the universe?
