But since many people like this topic, time-space communication is mixed in. The answer may be mixed with some scientific common sense, but it is not rigorous. For discussion only, let's see if we can help some friends solve their doubts.
First of all, we must find out why humans should hide when aliens come. Most Guamin believe that aliens are evil, mainly influenced by the law of "dark forest". The so-called dark forest law is a theory described by Liu in the science fiction novel Three-body. The main core is that there is a dark forest law in cosmic civilization, that is, all civilizations exclude the existence of other civilizations. Once other civilizations are discovered, they will be destroyed.
Like in a dark forest. All civilizations are hunters, hiding in dark camouflage and holding shotguns. Once they find their prey (other civilizations), they will shoot first. In the novel, Liu describes a "singer" civilization, who casually scans the universe while singing out-of-tune nursery rhymes. Once the signs of civilization are discovered, they are erased without verifying whether they are true or false.
In the novel, the civilization higher than the earth is a "three-body" civilization, and the three-body people sent a fleet to conquer the earth. In order to protect their homes from being smeared with charcoal, humans sent the coordinates of the three-person body to the universe. Singer civilization quickly discovered the three-person body civilization by following the coordinates, threw a light particle casually, and wiped out the three-person world.
Later, this civilization discovered the earth civilization, and casually threw out a two-way foil, just like a playing card without thickness, which floated to the solar system, causing the solar system to be hit by dimensionality reduction, disappearing from the three-dimensional world to the two-dimensional space and dying out.
Some people have analyzed that the "singer" civilization is only the advanced stage of the secondary civilization, and there are "four-dimensional" civilization and "zero-return" civilization on top of it, each of which is more advanced than the other, and its civilization degree and attack means are difficult to describe.
According to this theory, once human beings are discovered by aliens, and these aliens are much more civilized than human beings and have the ability to come to or attack the earth, then human beings will perish.
Many people in the world believe in the dark forest theory, and even some scientists think that the late physicist Hawking also thinks that aliens are up to no good. Therefore, in the novel Three-body, there are two well-known sayings, namely "Don't expose the coordinates of the earth" and "Don't answer the phone of aliens" in the universe. These two views are accepted by many people in the world and are constantly warned.
"Three-body" is very good-looking, I like it very much, and I admire Liu's imagination and ability to make up stories. But that doesn't mean I agree with them. Just because a novel is a novel doesn't mean that the universe is really like this. In my opinion, all human imagination, including most sci-fi works, only stays in the current ideology of human beings, so the dark forest consciousness is actually the embodiment of some modern human consciousness.
With the promotion of civilization, will a civilization higher than human civilization by one level or even higher still be this way of thinking? I'm not sure, but I think it's at least this dark forest thinking. My inference is that with the improvement of civilization, civilized bodies should produce more tolerance and win-win consciousness, which has been demonstrated in the history of human civilization development.
We reflect on the process of human civilization, from primitive race wars to ancient slavery and separatist wars, and then to modern United Nations. Isn't it a process from bloody to gradually tolerant? If Wen Mingzhen's universe developed in this way, why did advanced civilization attack us? Why are you hiding?
Secondly, when aliens come, can humans hide? According to Kardashev's theory of cosmic civilization index, human civilization has only reached the level of 0.73, which is far from the first-class civilization. Some scientists believe that it takes about 200 years for human beings to reach the first-class civilization and about 5000 years to reach the second-class civilization.
The ability to control and use energy is a sign of civilization. The energy used by the first-class civilization is equivalent to all the energy that the star shines on the parent star. When it reaches this level of civilization, it will be able to control all the energy resources of its parent star and move within the influence of this level of stars. As human beings on the earth, when they reach the first-class civilization, the energy they use can reach about1.74 *1kloc-0/7j/s, and they can control and use all the resources on the earth, move around in the solar system and emigrate to nearby planets.
By reaching the second civilization, human beings can control and utilize all the energy and resources of the solar system, including all the energy of the sun. The energy consumption reaches about 4 * 10 26J/s, and they can move and migrate to any star in the solar system or to nearby star systems, such as proxima centauri.
In this way, if aliens really invade the earth, this civilization must at least reach the second-class civilization, and its interstellar navigation ability and weapons and equipment ability have long been beyond the reach of human beings. If such aliens come, where can humans hide?
Escape, can you run past someone else's spaceship? Hiding underground, is there the ability of secondary civilization to dig underground? Therefore, I think that if aliens with secondary civilization or above really come to the earth, we can find out where humans are hiding, whether they are fishing in the sky or in the sea. Even people don't need to do it themselves. A robot dog can bite you out.
Or we don't need to catch them at all, just make some kind of sound wave and report to them. If you meet more advanced civilizations such as "singer" or even "four-dimensional" and "zero", you will lose the earth and even the solar system with a wave of your hand. Where will humans hide? Or in other words, if you can escape the blow of this civilization, you have the ability to fight it, and your civilization level is no longer 0.73.
So don't be fooled by science fiction movies. If different levels of Wen Mingzhen are hostile, there is no confrontation at all. During the War of Resistance against Japanese Aggression period, the Japanese devils were more advanced in equipment than the Eighth Route Army, and the Eighth Route Army was able to win the battle because of the same level of civilization. The japs ran wild for a while, but the floor was covered with mats, which were only a little higher.
If there are aliens, if they are at the same level as human civilization, only a little higher, they can't come to the earth to find human trouble; If the degree of civilization is higher than that of human beings, there is no need for human beings to hide, and they can only be slaughtered and destroyed.
It's kind of like a war between humans and ants. Even if ants are hidden underground, people can dig them out with excavators, or just smoke into the hole and pour some water into it, and those ants have to worship. Of course, ants can also hide in places where humans can't find them, such as the depths of virgin forests.
But this does not mean that ants can escape, but that humans don't want to kill them. If humans want to kill all ants, they can do it with their current ability. Of course, after that, the earth may be uninhabitable. But the earth is not the hometown of aliens. If aliens want to destroy mankind, it is not a pity to destroy the earth.
So my point is: high-level aliens will never be enemies of mankind at any time, and they may be more friends when they come; If there are really high-level aliens invading the earth, human beings can't hide if they want to, and there is no need to hide.
