There are two axioms in the dark forest law ~

Civilization takes survival as the first law.

Civilization continues to expand and develop, and the total amount of material remains unchanged.

Two important inferences:

Chain of doubt, one civilization cannot judge whether another civilization is good or evil.

With the explosion of technology, a civilized technology can develop explosively, and a weak civilization may soon catch up with or even surpass a developed civilization.

With these four laws, plus a major premise, the universe is big enough and the distance between civilizations is far enough, so reasoning can be carried out.

The universe is so big, if there are multiple civilizations, there is no connection at first. With the development of science and technology, civilization A can discover civilization B and announce its existence to other civilizations.

If civilization A discovers civilization B, it is even more suspicious that chain A cannot judge whether B is good or evil. According to the axiom 1, it will not take the initiative to contact for the survival of civilization. According to the theory of technological explosion, civilization B may develop rapidly and surpass civilization A, and according to axiom 2, civilization B may pose a threat to A, so the conclusion is:

Civilization and civilization are invisible to each other, and the best solution is not to actively seek (increase the risk of exposing yourself), as long as it is discovered, untouched and destroyed from a distance.

Like a dark forest. There are many hunters, all with guns, good and bad. In order to protect themselves, they can only hide in the dark and shoot directly as long as there is light or sound. So it is called the dark forest law.
