In the 1950s of the last world, with the help of science and technology, mankind finally realized the dream of flying out of the earth. After we walked out of the earth, we truly understood the vastness of the universe and the smallness of the earth.
When we recognize the vastness of the universe, thinking about extraterrestrial civilization has become a hot spot. In the opinion of scientists, a small galaxy has at least 100 billion stars and hundreds of billions of terrestrial planets, and within an observable range of 93 billion years, there are at least trillions of large galaxies like the Milky Way. , The number of terrestrial planets is too large to be counted.
With such a huge base, there is basically no doubt about the existence of alien civilizations. So not long after human beings walked out of the earth, we began a great search for extraterrestrial civilization. By launching the Voyager probe, scientists actively launch human civilization signals into the depths of the starry sky, and continuously search for possible alien civilization signals in the universe through radio telescopes.
Mankind has worked hard for more than half a century to search for extraterrestrial civilizations through these methods, but until now, we still haven’t found anything. Not to mention seeing an alien civilization, even if it is a possible trace of the existence of an alien civilization, we have not found one.
This situation has not overthrown scientists’ enthusiasm for exploring extraterrestrial civilizations. With the rapid development of human science and technology, the cognition of the universe has been continuously improved. Scientists have higher and higher expectations for finding alien civilizations. As for human beings unable to find alien civilizations, scientists have also given a variety of guesses. The most reliable reason is that distance and speed limit us.
We all know that the universe is so vast that we cannot imagine it. The distance of the universe is based on light years and the speed is based on the speed of light. The speed of light is very fast in our eyes, but it is only the speed of tortoise in the universe, and to break the speed of light, it needs to be applied to the distortion of time and space in general relativity.
We must understand that the speed limit of an object is the speed of light, and the speed of a mass object can only approach the speed of light infinitely. Even so, the speed of light is not impossible to break through, but the object itself cannot be broken through, and it needs to be applied to the distortion of space. Space-time can be warped is a scientifically proven theory. As long as we can warp the space around the spacecraft, then space can theoretically fly the spacecraft faster than light.
After breaking through the speed of light, we can also conduct primary interstellar voyages. At that time, we can search within the Milky Way, and we believe that many living planets and alien civilizations will be discovered. So a question arises: If human beings discover low-level civilization planets during interstellar voyages, what will we do?
There are countless intelligent civilizations in the universe, and the universe has a history of 13.8 billion years. The civilizations born in such a long time must be sequential. Civilizations born before humans may be much stronger than us, but later than humans. The civilization that was born may not be as advanced as ours, and may even be in a very primitive stage of evolution.
Humans were also primitive Homo sapiens tens of thousands of years ago, and they have not yet truly evolved into modern humans. We have become an interstellar civilization. When sailing between the stars, it is inevitable that we will find some relatively primitive low-level civilization planets. What kind of attitude will we show at this time, whether to plunder or get along?
Many people may say that low-level civilizations are so primitive and those natives are so ignorant. Is it human work for us to plunder them? Therefore, we should get along well with these low-level intelligent beings. So is this possibility possible? The possibility naturally exists, but the probability is not high.
Let me ask, is there absolute fairness and peace within mankind? I believe everyone understands that this is impossible. From ancient times to the present, the internal wars of mankind have never really stopped. Even in the modern era of peace, small-scale conflicts and wars often occur. The 5,000-year history of human civilization is actually a history of war. It can be seen that human beings are not very kind and peaceful civilizations.
There is a war factor in the bones of mankind, a conquering factor, the strong bullying the weak, and the weak country has no diplomacy. This is an immutable truth. Humans and alien civilizations are two completely different races. If they are civilizations with equal technological strength, they may be able to live in peace at the same level.
But if there are two civilizations with relatively large levels of difference, the possibility of equal coexistence will be very small. We have encountered a low-level civilization. These indigenous people will not be placed on an equal position in the eyes of mankind. We will present a superior attitude. In the eyes of lower civilizations, human beings descend from the sky, just like gods, and they are more of a kind of fear for us.
Of course, the possibility of interstellar war between humans and lower civilizations will also be very small. The reason is that there is no need for us to actively colonize, lower civilizations will automatically come by and worship humans as gods. At this time, do we still need to start a war? Of course not, as long as we show power a little bit (in the eyes of the indigenous people, it is a supernatural power), they will listen to humans.
If human beings find that there are precious resources we need on this low-level civilization planet, we will colonize this planet to mine resources, and then let the natives of this planet serve us to mine resources for free. In the eyes of these lower civilizations, it is an honor to be able to serve gods like humans.
After we finish mining the precious resources of this planet, we will naturally not stay on this planet, and then leave this planet by spacecraft to continue interstellar travel, looking for other resource planets. Before humans leave, we may tell these indigenous people that we will return at some point in the future.
After human beings leave, the indigenous people of lower civilizations will record the human gods coming to this planet through carving and other methods for future generations to remember. But we understand that the words that humans said to lower civilizations before they left were only a comfort. We know that the universe is vast and vast. After we leave this planet, we may never return in the future.
This is the most reliable way for human beings to deal with the discovery of low-level civilization planets during interstellar travel. Of course, this is on the premise that there are important resources needed by mankind on this planet. If the planet is very barren and there are no useful resources, then we may not have contact with lower civilizations, because in our opinion , It is completely meaningless.
Humans will deal with low-level civilizations in this way. When alien civilizations, which are also much higher than human civilizations, carry out interstellar voyages, they may also adopt such methods when they discover that the earth and humans are the same. In fact, some myths and legends in the ancient times of the earth may be that alien civilizations came to the earth for a period of time. The ancient humans believed that they were gods in the sky. They recorded some of their deeds and later adapted them into myths and legends.
There are also some particularly magnificent ancient buildings on the earth, such as the pyramids in Egypt. Such magnificent buildings were difficult to build by the ancient Egyptians more than 4,000 years ago. Some scientists have speculated that the Egyptian pyramids may have been built with the help of alien civilizations. If this guess is correct, a group of aliens came to the earth in ancient Egypt 4000 years ago and stayed in Egypt for a period of time.
Of course, all of this is just a conjecture at present. Human beings are still far from realizing interstellar navigation, and it will take a very long time to develop. It may be thousands of years or even tens of thousands of years before we will be able to explore the entire galaxy.
