When human beings walked out of the earth to see the vast universe with the help of science and technology, an eternal topic appeared, that is, does alien civilization exist? Maybe before mankind got out of the earth, many people would think: mankind is the only intelligent civilization in the universe.
But when we have truly seen the vastness of the universe, few people have such obsessions anymore. More people believe that: extraterrestrial civilization exists, and scientists are more steadfast about it. Let’s not look at the observable universe of 93 billion light-years. Take the small Milky Way as an example. The Milky Way with a diameter of about 100,000 light-years contains 100-400 billion stars.
Each star basically forms a star system, with varying numbers of terrestrial planets orbiting. It is conservatively estimated that the number of terrestrial planets in the galaxy has reached at least one trillion. Even if it is a very small probability that life will be born and a smart civilization will be born, there are many life planets in the galaxy, and there will be a high probability that there will be a smart civilization.
In the current observable universe, there are at least trillions of galaxies like the Milky Way, so the number of cosmic civilizations may be too large for us to estimate. Only because the distance between galaxies is based on light-years, it is too far, and it is difficult to reach between civilizations.
However, with the continuous advancement of human science and technology, once we become an interstellar civilization in the future, we will be able to leave the solar system for interstellar voyages. In the process of interstellar voyage, it is inevitable to encounter other intelligent civilizations, so an interesting topic arises here: if a low-level civilization planet is discovered by humans, will we choose to destroy it?
Many people may think that human beings are very kind and will not bully weak civilizations, let alone eliminate low-level civilizations. Is this really true? If you think so, you are wrong. Are human beings a kind civilization? This may be difficult for us to define.
Let’s not consider what kind of attitude human beings will have towards alien civilization. Let’s first look at whether human beings are harmonious, and whether human beings are harmonious? the answer is negative. It has been more than 6,000 years since human beings formed a civilization. In these years, the contradictions within human beings have never stopped. From ancient times to the present, wars of all sizes have not ceased for a moment.
Even now in the peaceful age, there are often various frictions within human beings, and some small local wars have broken out. From the internal situation of human beings, we can see that human beings are not a civilization that likes peace. In the genetic backbone of human beings, greed and struggle will always exist. Even if we go to the starry sky and become an interstellar civilization in the future, the internal wars of mankind may not be completely eliminated.
Human beings are a civilization that likes to fight. When we become an interstellar civilization and have the ability to get out of the solar system, the contradictions within human beings may be reduced very weakly, and then point the finger at the stars of the universe, go to other galaxies to find a civilization of wisdom, and then develop New battle modes and venues.
There are countless civilizations in the universe, and in the journey of human beings’ interstellar exploration, they will encounter various intelligent civilizations. If we find a low-level civilization that has not yet reached the interstellar, human attitudes may be adjusted according to the conditions of this civilization. No matter how it is adjusted, it is difficult for humans to cooperate and trade fairly with the natives of low-level civilization planets.
When mankind discovers low-level civilizations, there are nothing more than two attitudes, one is to coexist peacefully and the other is to destroy it and completely colonize and occupy the planet. So under what circumstances will human beings peacefully cooperate with lower-level civilizations? Many people may say that the smaller the power gap between low-level civilizations and humans, the higher the possibility of peaceful cooperation.
If you think so, you may be wrong. The greater the power gap between low-level civilizations and humans, the higher the possibility of peaceful cooperation. Some people may say, how is this possible? The greater the gap between human strength and human strength, wouldn’t it be easier for us to eliminate these original inhabitants? In this case, we still need to get along with the original inhabitants in peace?
In fact, as long as we think about it carefully and analyze it, you will understand the truth. When mankind discovers a low-level civilization planet, we value two points. One is whether the environment of this planet is suitable for human survival, and the second is whether there are resources and energy that are very important to mankind on this planet.
Judging the value of a planet is nothing more than considering these two aspects. If the environment of this low-level civilization planet is not suitable for human survival, there is no precious resources that humans need. We will not waste time on one planet, but continue to search for other civilized planets.
If this low-level civilization planet is suitable for the survival of mankind, and there are precious resources we need, then mankind will not miss it, colonization is inevitable. At this time, we must take measures based on the civilization strength of the indigenous inhabitants on this planet. If the indigenous inhabitants are still in the primitive civilization era, they have no understanding of the universe or alien civilization.
At this time, when the human spacecraft descended on this planet, what would the original inhabitants think? First, they will feel scared and horrified, because they don’t know what these things are coming down from the sky? If the original inhabitants have myths and legends, they may regard humans as worshipping gods. And human beings can also pretend to be gods and show some technologies to these primitive residents. These technologies may be celestial arts in the eyes of primitive intelligent beings.
When human beings become the gods in the eyes of the original inhabitants of low-level civilization planets, we can use the identities of gods to hire these original inhabitants for free to help us mine resources. And human beings can take this planet for granted and be welcomed by the original inhabitants, because we are gods in the sky in their eyes, and being able to live on their planet is a kind of supreme glory.
But if the original inhabitants of the low-level civilization planet have already walked out of the primitive age of ignorance, and entered the preliminary technological age. It is naturally impossible for humans to pretend to be immortals. It is like we don’t believe in the existence of immortals. Even if a powerful spacecraft descends on the earth tomorrow, we will only think that it is an alien civilization in the universe.
After mankind loses the disguised identity of a fairy, can we still occupy this low-level civilization planet for free and without cost? The answer is impossible. If we want to live on this planet, we will be hindered by the original inhabitants. Even if we want to mine resources, humans need to exchange other things with lower civilizations.
At this time, it is difficult for humans to form a completely equal cooperative relationship with the lower civilizations. The lower civilizations will guard us and think of taking advantage of mankind. And human beings will also think about how to get more benefits from the low-level civilization, and even occupy resources completely for free. Under this contradiction, humans may launch interstellar wars, completely annihilate this low-level civilization, and then occupy the entire planet’s resources.
Through the above analysis, I believe many friends have understood the way. It can be seen that the cosmic civilizations also need strength to speak, and only the stronger the strength, the more right to speak. And the earth may also face visits from advanced civilizations in the future. If the strength of the incoming alien civilization is very different from that of humans, it is safe for humans, because in the eyes of advanced civilizations, humans are just as weak as ants. Exist, I don’t even bother to eliminate it.
But if the strength of the incoming alien civilization and human beings are not particularly great, it may be the most dangerous for human beings. For this reason, Hawking has repeatedly issued warnings: let humans not try to contact alien civilizations, whether they are advanced civilizations or civilizations that are not very different from humans, once they come to the solar system, they will be both for the earth and humans. It may be a very dangerous thing.
If we want to get in touch with alien civilizations, it’s best to wait until humans have developed to a higher level and become an interstellar civilization, and after we have the ability to navigate between the stars, we will take the initiative to go out and search for it. The current human strength is not even a first-level civilization, it is also a low-level civilization. Once encountered any interstellar civilization, if it is hostile to us, then humanity may usher in destruction.
