I Have A Super USB Drive - Chapter 423
Chapter 416 Fermi Paradox
Chen Chen knows that the so-called “Great Filter Theory of Civilization” is actually an explanation of “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, placed on ordinary people, is just a curiosity about the unknown and imagination of the vast universe, but in the mind of this Nobel Prize winner, it presents a reality of careful thought and fear——
Looking at the data of the entire universe, the human observable universe is 12.7 billion light-years away, and the age of the universe is 136.2 (with an error of 120) billion years. The entire universe has hundreds of billions or more of outer river systems, and the Milky Way is just for all living beings. First, it’s like a grain of sand on a beach, even worse.
In such a large-scale macro-scale and a long period of time, why have we humans not discovered the existence of other alien life?
This question may be a bit general, so after research, scientists decided to refine the question more delicately-first, considering the inbreakability of the speed of light, and the nearest river system to the Milky Way is also 3 million light-years away, so they don’t consider it. The existence of life in the outer river system.
Secondly, some people always think that the life forms in the universe are not limited to carbon-based life. Therefore, other types of life may exist, but humans are not aware of it. In particular, many people will say the most well-known “silicon-based life”. This example.
However, according to life being at least a complex individual that exchanges materials selectively with the surrounding environment, and there is no environment outside of basic physics in the entire universe, that is to say, the basic laws of the entire universe are unified, and they are all composed of four The basic forces, as well as the material composition of atoms, protons, electrons, etc., are also arranged in the same periodic table, so the only element that can give birth to life is the most stable carbon element.
The carbon element has a structure of 4 electrons in the outermost layer, which is equivalent to having four hands. Each hand can grasp another atom, and can even hold hands with other carbon atoms to form 4 stable covalent bonds. It is already the limit of the number of chemical bonds formed by elements.
In addition to carbon, silicon is indeed the easiest to give birth to life in the entire universe. However, the number of extranuclear electrons of silicon atoms is one more layer than that of carbon atoms, and the electromagnetic force is weak. Not as good as carbon-based life.
Carbon element is like a social flower, which can attract various atoms to combine with it, and the types of compounds formed with other elements are almost unlimited.
Therefore, it can be said that if there are other lives in the universe except human beings, then 90% of them are carbon-based, 9% are silicon-based, and the remaining 1% are other forms of life.
Therefore, after compressing the problem of cosmic life to the Milky Way and the carbon-based scale, we will get such data-the Milky Way is about 12.5 billion years old, two thousand light-years in thickness, 160,000 light-years in diameter, and approximately There are 100 billion sun-like stars, and planets are countless.
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 on the scale of the Milky Way.
Based on the current knowledge of physics, chemistry, biology, cosmology, and sociology, scientists believe that at the speed of human technology development, if an alien civilization develops only 10,000 years earlier than the earth, then its traces are now The Milky Way should have been filled long ago, and the current Milky Way should actually have been full of interstellar civilization colonizing everywhere.
But the fact is that, apart from some rumors, humans cannot find any strong evidence of the existence of aliens on the earth nowadays. Even the radio telescopes cannot find the slightest alien spacecraft or alien projects…
So, this brings me back to Fermi’s question, those aliens, where are they?
This question has become the classic “Fermi Paradox”, which has been talked about by the scientific community to this day.
But at this moment, watching the end of the video, Chen Chen showed a sullen expression of being played.
Xiao X looked back at Chen Chen, then watched the video that was turned off, and couldn’t help asking, “Your Godfather, is there anything wrong with the other party?”
“No, I totally agree with him.”
Chen Chen nodded, and then showed a weird look, “But what he said are things I already know. Strictly speaking, his entire video only reminds me that human beings will encounter crises. I seem to be farting!”
Xiao X scratched his head suddenly, showing a puzzled look.
“If you just listen to what he said, it would be really bluffing. It is also a civilization filter and a U-disk butterfly effect. But in fact, I know everything he said. I really want to know, but he doesn’t say a word. mention.”
Chen Chen spread his hands, “What is the theory of the Great Filter of Civilization? It is actually one of the explanations of the Fermi Paradox. A man named Robin Hansen proposed this concept. He divided the evolution from life to civilization into Nine stages, starting from a suitable planetary system, to the birth of self-replicating molecules, to single-cell life, sexual reproduction, multi-cell life, animals, to the stage we are currently in, and the final stage is interstellar colonization …”
“In other words, he believes that human civilization is currently in the eighth stage of the big filter, and the final stage of interstellar colonization, the only thing left behind is controllable nuclear fusion.”
“Controllable nuclear fusion, have we achieved it?”
Xiao X hurriedly called.
“Yes.”
Chen Chen nodded, “Someone has calculated that even if the chemical energy of the whole earth is used, it cannot support human beings to fly from the solar system to the nearest centaur galaxy in a few decades. This shows that the energy provided by chemical fuel is Very poor, its existence is at best a transitional product of mankind, and controlled nuclear fusion should be the initial energy system for mankind to enter space.”
Xiao X heard that he checked it on the Internet, and then smiled, “If it is only from the point of view of evolution, this theory is valid. It took 4.5 billion years for the earth to give birth to humans, and it took 20 It took thousands of years before science was born. In such a long history, as long as there is one devastating disaster, human civilization may be interrupted.”
“So if there is no big filter, then life will surely spring up like bamboo shoots after the rain, and there will surely be a large number of civilizations leading mankind, then aliens have found the earth long ago. Not only that, but now I am also can do it.”
Chen Chen nodded. He knew that the reason why Xiao X said this was because Xiao X could already make his own von Neumann detector with his current ability.
The von Neumann probe is a self-replicating probe designed to use the raw materials found in any star system to replicate itself and explore the universe, named after the mathematician John von Neumann.
All the functions of this kind of detector are based on the existing technology of mankind, but because of its self-replicating characteristics, according to scientists’ calculations, it only takes a million years for mankind to make such a detector. The probe can also cover the entire galaxy.
Then we can prove in reverse that, since we have not found any other civilized von Neumann detectors, can we prove that there is no civilization in the galaxy, or that there is no civilization that exceeds humanity for more than a million years?
“So, there must be something like a big filter that hinders the bustling and prosperous scene of civilization.”
Xiao X finally concluded.
“This is indeed the truth you said.”
Chen Chen replied, “That’s why I said that Zhao Shanhe was talking about farting. The big filter in his mouth was obviously something else, but it didn’t explain what it was. What was it if it wasn’t farting?”
“Not only that, the Gaia in his mouth, and the so-called earth disaster against human civilization, is actually a very common immune response.”
Chen Chen continued, “The metaphysical argument is that the earth treats humans as alien elements. The proliferation and behavior of humans has harmed 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, Marburg virus, Sudan Ebola virus, and Zaire Ebola virus are the strongest powers displayed by nature.”
“To put it bluntly, it is that human development destroys the ecological balance, which leads to changes in the earth’s environment, and these immune responses, including viruses and natural disasters, actually disrupt the ecological balance after the chain reaction.”
“Ah, it’s so bad.”
Following Chen Chen’s guidance, Xiao X slowly woke up.
“Not only that, he mentioned that he is going to go to the movie “Israel”, and the U disk will have an impact on reality. These are all things I already know, even the two “memes and antimemes”. He didn’t explain this concept to me at all, but just said the name.”
Chen Chen sneered, “In short, he seems to have told me a lot, but in fact, after thinking about it, he didn’t say anything at all. In the whole article, only the warning of the so-called ‘Great Filter of Civilization’ is the only thing.”
“Even this warning can be understood in terms of the law of large numbers-in a large number of repeated occurrences of random events, there is often an almost inevitable law. This law is the law of large numbers. In layman’s terms, it is under constant conditions. Repeat the experiment many times, the frequency of random events is similar to its probability, and there is a certain kind of inevitability in accident… As human civilization develops, it will inevitably encounter various accidents and crises. This is a way to think with your feet. The fact that comes to mind.”
When Xiao X heard the words, he thought suddenly, “I understand what you mean. The more advanced the technology, the further and farther away the human beings on the road to death. This is the case with the emergence of nuclear weapons. It is also what mankind has experienced. The first test of destruction, and the shadow of nuclear war has been looming over mankind since the latter part of the last century. Even today, it does not end. And as mankind’s technology becomes more advanced, nuclear weapons are just the beginning?
“Yes, nuclear weapons are just the beginning. Then there are genetic weapons, biochemical weapons, anti-matter weapons, and even the memetic weapons we have begun to come into contact with… These weapons make human civilization possible at any time by our own weapons. Destroying, just like those U disk planes we entered, is inevitable by chance.”
“Is this the truth that all the human planes in the USB flash drive are destroyed?”
Xiao X suddenly felt surprised.
“These are just my guesses, they are definitely not all right.”
Chen Chen shook his head, “But it’s better than this guy’s explanation of half a bucket of water.”
“Maybe the’civilization filter’ in his mouth is not such an abstract concept, but a higher-level weapon similar to memetic technology and even causality?”
Xiao X suddenly reminded.
“What you said is also possible.”
Chen Chen pondered for a while, silently wrote down Xiao X’s reminder, and then said again, “It depends on what he intended to leave this video. Now there are two possibilities. The first is that this video is his ” The last words left before “Black Hole Surface” are to warn the holder of the second USB flash drive, but he did not expect that he would eventually fail and become one with antimemetic, instead, he wanted to regain his body. So I changed my mind and came to hurt me.”
“The second possibility is that he went to the “Black Hole Surface” plane itself to become one with antimeme, and this video is another trap, just like the four horror movies he put in the USB flash drive. Same, but he was destroyed by me before he was triggered.”
Having said that, Chen Chen took a deep breath and said, “I personally prefer the second one, because the first one may not explain why he puts four horror movies in it But what is the specific situation? It is very simple to verify, X, now that we know his name, you try to search for information about Zhao Shanhe from the entire World Wide Web. If he is really that antimemetic, he will be killed by me at this time. Later, there should be clues about him on the Internet.”
“Understand.”
Xiao X suddenly closed his eyes, and once again connected to the network to sweep up a large area.
This scan took several hours.
Four hours later, Xiao X opened his eyes again, but at this time there was also a flash of surprise in her eyes, “Your Godfather, I found Zhao Shanhe’s information!”
“Take a look!”
Chen Chen said quickly.
Suddenly, a webpage appeared in the void in front of Chen Chen. The year of the webpage was 1988, and the above was an information sheet.
On the information sheet, it is a file.
