I Have A Super USB Drive

Four hundred and sixteen - Fermi Paradox

Chen Chen knew that the so-called Great Filter Theory of Civilization was actually an explanation of the "Fermi Paradox".

In 1950, when North American physicist Fermi was discussing the issue of flying saucers and aliens with people, he once asked a question: "Those aliens, where are they?"

This question, put on ordinary people, is just a curiosity about the unknown and imagination about the vast universe, but in the mind of this Nobel Prize winner, it presents a reality that is terribly thoughtful——

Looking at the data of the entire universe, the scope of the observable universe for human beings is 12.7 billion light years, and the age of the universe is 13.62 billion years (error 120 million). One, it's like a grain of sand on a beach, or even worse.

On such a large scale and in a long time, why haven't we humans discovered the existence of other extraterrestrial life?

This question may be somewhat general, so after research, scientists decided to refine the question more finely—first, considering the unbreakable speed of light, and the nearest galaxy to the Milky Way is 3 million light-years away, so it is not considered The existence of life in the outer galactic system.

Secondly, some people always think that the life forms in the universe are not limited to carbon-based life, so other types of life may exist, but humans are not aware of it, especially many people will give an example of the most well-known "silicon-based life" This example.

However, according to the view that life is at least a complex individual that selectively exchanges matter with the surrounding environment, and there is no environment other than basic physics in the entire universe, that is to say, the unity of the basic laws of the entire universe is composed of four The big fundamental force, as well as atoms, protons, electrons and other substances, are also arranged in the same periodic table, so the only element that can give birth to life is the most stable carbon element.

Carbon has a structure of 4 electrons in the outermost layer, which is equivalent to having four hands, each of which can hold another atom, and even hold hands with other carbon atoms to form 4 stable covalent bonds. Already the limit for the number of elements that can form chemical bonds.

Besides carbon, silicon is indeed the most likely to give birth to life in the entire universe, but the number of extranuclear electron layers of silicon atoms is one more than that of carbon atoms, and the electromagnetic force is weak. Not as good as carbon-based life.

Carbon is like a courtesan that can attract all kinds of different atoms to combine with it, and the types of compounds it can form with other elements are almost limitless.

Therefore, it can be said that if there are indeed other lives in the universe other than human beings, then 90% of them are carbon-based, 9% are silicon-based, and the remaining 1% is other forms of life.

Therefore, after compressing the problem of life in the universe to the scale of the Milky Way and the carbon base, we will get such a data-the Milky Way is about 12.5 billion years old, 2,000 light-years thick, 160,000 light-years in diameter, and about There are 100 billion sun-like stars and countless planets.

If the emergence of human beings is a miracle in the universe, no matter how small the data of this miracle is, it will be surprisingly large when placed in a star with the scale of the Milky Way.

According to the current knowledge of physics, chemistry, biology, cosmology and sociology, scientists believe that with the development speed of human science and technology, if there is an alien civilization that is only 10,000 years earlier than the development of the earth, then its traces It should have been full of the Milky Way long ago. The current Milky Way should have been full of colonizing interstellar civilizations long ago.

But the fact is that, except for some rumors, human beings can't find any strong evidence of the existence of aliens on the earth today, and even radio telescopes can't find the slightest trace of alien spacecraft or alien engineering...

So, this goes back to Fermi's previous question, those aliens, where are they?

This question has become the classic "Fermi Paradox", which is still talked about by the scientific community.

But at this moment, watching the video end, Chen Chen showed a sullen expression of being played.

Little X looked back at Chen Chen, then at the turned off video, and couldn't help asking, "Your Excellency, Godfather, is there anything wrong with what the other party said?"

"No, I totally agree with him."

Chen Chen nodded, but then showed a strange look, "But what he said is what I already know. Strictly speaking, his entire video only reminded me that human beings will encounter crises one by one. It looks like fart to me!"

Little X scratched his head suddenly, showing a puzzled expression.

"If you just listen to what he said, it's really bluffing, it's a civilization filter, and a U disk butterfly effect, but in fact, I know everything he said, and what I really want to know, he doesn't say a word. carry."

Chen Chen spread his hands, "What is the Great Filter Theory of Civilization? It's actually one of the explanations of the Fermi Paradox. A person named Robin Hansen proposed this concept. He divided the evolution from life to civilization into 9 stages, starting from a suitable planetary system, to the birth of self-replicating molecules, to single-celled life, sexual reproduction, multi-cellular life, animals, to the stage we are currently in, and the final stage is interstellar colonization ..."

"That is to say, he believes that human civilization is currently in the eighth stage of the Great Filter, and the final stage of interstellar colonization is short of one thing—controllable nuclear fusion."

"Controllable nuclear fusion, have we achieved it?"

Little X called out hastily.

"Yes."

Chen Chen nodded, "Someone once calculated that even if all the chemical energy of the entire earth is used, it will not be able to support humans to fly from the solar system to the nearest centaur galaxy within a few decades, which means that the energy provided by chemical fuel is It is very poor, its existence is at most a transitional product of human beings, and controllable nuclear fusion should be the initial energy system for human beings to enter space."

Xiao X heard that he checked it online, and then laughed, "If only from the perspective of evolution, this theory is valid. It took the earth 4.5 billion years to conceive human beings, and it took 200 million years for human beings to conceive." It took tens of thousands of years for science to be born, and in such a long history, as long as there is a devastating disaster, human civilization may be interrupted."

"So, if there is no big filter, then life will spring up everywhere like mushrooms after rain, and there will be a large number of civilizations ahead of human beings, and aliens will have found the earth long ago. Not only that, even I am now can do it."

Chen Chen nodded. He knew that the reason why little X said this was because with his current ability, he could already make his own von Neumann detector.

The von Neumann probe, a self-replicating probe designed to replicate itself and explore the universe using the raw materials found in any star system, is named after mathematician John von Neumann.

All the functions of this kind of detector are based on the existing technology of human beings, but because of its self-replicating characteristics, according to the calculations of scientists, it only takes one million years for human beings to manufacture such a detector. Probes could also fill the entire Milky Way.

Then it can be proved inversely, since we have not discovered any von Neumann detectors of other civilizations so far, can it be proved that there is no civilization in the Milky Way, or for the time being, there is no civilization that exceeds human beings for more than one million years?

"So, there must be something like a big filter that hinders the bustling and prosperous scene between civilizations."

Little X finally deduced.

"That's exactly what you said."

Chen Chen replied, "That's why I said that what Zhao Shanhe is talking about is farting. The big filter in his mouth is obviously something else, but it doesn't explain what it is. If it's not farting, what is it?"

"Not only that, but the Gaia he mentioned, and the so-called earth's disaster against human civilization, are actually just a very common immune response."

Chen Chen continued, "The metaphysical point of view is that the earth regards human beings as alien elements. The proliferation and behavior of human beings has violated the health of the earth. The earth does not like to accommodate so many humans, so it releases viruses and kills humans. To maintain the balance of the biosphere, the Marburg virus, the Sudan Ebola virus, and the Zaire Ebola virus are all the strongest forces displayed by nature."

"To put it bluntly, it is actually human development that destroys the ecological balance, which leads to changes in the earth's environment, and these immune responses, including viruses and natural disasters, are actually a chain reaction after the destruction of the ecological balance."

"Ah, what a pit."

Following Chen Chen's guidance, Xiao X slowly came to his senses.

"Not only that, he mentioned that he is going to the movie "Alien", and that the USB drive will affect reality. He didn't explain this concept to me at all, but just said the name."

Chen Chen sneered, "Anyway, he seems to have told me a lot, but actually, after thinking about it, he didn't say anything at all. The whole article is just a warning from the so-called 'civilization filter'."

"Even this warning can be understood by the law of large numbers - in the repeated appearance of a large number of random events, there is often an almost inevitable law. This law is the law of large numbers. In layman's terms, it means that under constant conditions, Repeat the experiment many times, the frequency of random events is close to its probability, and there is some kind of inevitability in the accidental... With the development of human civilization, various accidents and crises are bound to be encountered. Facts that come to mind.”

Little X was thoughtful when he heard the words, "I understand what you mean. The more advanced the technology, the further the human being will be on the road to death. The emergence of nuclear weapons is like this, and it is also what human beings have experienced. The first test of destruction, and the shadow of nuclear war has been hanging over mankind since the end of the last century, and it is not over even today, and as human technology becomes more and more advanced, nuclear weapons are just the beginning?"

"That's right, nuclear weapons are just the beginning, followed by genetic weapons, biochemical weapons, antimatter weapons, and even meme weapons that we have come into contact with... These weapons make human civilization likely to be overthrown by the weapons we make at any time. Destruction, just like those U-disk planes we entered, is accidental and inevitable."

"Is this the truth about the destruction of all human planes in the USB flash drive?"

Little X was startled suddenly.

"These are just my guesses, and they are definitely not all right."

Chen Chen shook his head, "But it's better than this guy's half-baked explanation."

"Perhaps the 'civilization filter' he mentioned is not such an abstract concept, but a higher-level weapon like meme technology, or even the law of causality?"

Xiao X reminded suddenly.

"It's also possible what you said."

Chen Chen pondered for a while, then silently wrote down Xiao X's reminder, and then said again, "It all depends on why he left this video. Now there are two possibilities. The first is that this video is his going to " The last words left before "The Surface of the Black Hole" were to warn the holder of the second USB flash drive, but he did not expect that he would fail in the end. After merging with the antimeme, he instead wanted to regain his body So he changed his mind and came to harm me."

"The second possibility is that he went to the plane of "Black Hole Surface" itself to merge with the antimeme, and this video is another trap, just like the four horror movies he put in the U disk It's the same, but before the trigger, he was eliminated by me."

Having said that, Chen Chen took a deep breath and said, "I personally prefer the second option, because the first option may not be able to explain why he included four horror movies."

"However, it is very simple to verify the specific situation. X, now that we know his name, try to search for information about Zhao Shanhe from the entire World Wide Web. If he is really the inverse model Because, after being killed by me at this time, there should be some clues about him on the Internet."

"clear."

Little X closed his eyes immediately, connected to the network again and started sweeping in a large area.

This scan takes hours.

Four hours later, Xiao X opened her eyes again, but at this time her eyes flashed with surprise, "Your Excellency Godfather, I found Zhao Shanhe's information!"

"Take it and see!"

Chen Chen said hastily.

Suddenly, a webpage appeared in the void in front of Chen Chen. The year of the webpage was 1988, and there was an information sheet on it.

On the information sheet, there is a file.
