Xu Liang found a stone and sat down, and asked Duan Qing to talk about the "Civilization Arena".

This thing, this term, has appeared in their discussions many times, and it is indeed time to completely clarify the original situation.

Xu Liang dragged his chin and looked at Duan Qing, his expression was very serious, he was even ready to listen to a lot of terms about technology. Unexpectedly, he guessed wrong about this: what Duan Qing said was very simple and easy to understand, and even African refugees could understand it.

Duan Qing glanced at her sister Duan Han: "You come?" Or me? ”

Duan Han didn't raise his head: "You." "Now that she has a new toy, Super Pliers, she really doesn't care about anything when she gets up to research.

Duanqing sighed and said, "Okay." ”

"The Arena of Civilization is actually a place where different civilizations are directly connected. So if we want to make this problem clear, we must first briefly talk about the relationship between various civilizations in the universe. ”

"Is the relationship between different civilizations harmonious and co-developing? Or are you dead and incompatible? That's actually a very interesting question. ”

Xu Liang interjected: "The relationship between different civilizations? Shouldn't it be to follow the laws of the dark forest? ”

Duan Qing: "Well, there is indeed such a dark forest hypothesis. This is a scientific hypothesis that is very well known in the literary circles of our country. ”

What did Duanqing say...... No matter how you listen to it, there is a smell of mockery.

"Actually." She continued, "If the chain of suspicion + long-distance communication + various other qualifications are met, the hypothesis that the universe is a dark forest is indeed possible. That said, it is very likely that all biological civilizations will have to hide themselves from being killed by higher civilizations. However, there are too many qualifications behind the law of the dark forest! So much so that if one of the qualifications is wrong, then the hypothesis is not valid. ”

"In fact, the Dark Forest Hypothesis is not the only one regarding the relationship between civilizations in the universe, there are various other possible speculations, all of which may be true. And the one I am going to talk about next is particularly in line with the current situation. ”

Xu Liang: "Another hypothesis? Different from the Dark Forest? ”

"Yes." Duan Qing said, "Correspondingly, you can call it the dense forest hypothesis. ”

The Dense Forest Hypothesis?

Xu Liang frowned and thought for a long time: "Is this in the cottage Liu?" ”

"Ahem, the name doesn't matter." Duan Qing, "What matters is the content of the hypothesis. ”

She shook the display board in her hand, indicating the source of these contents: "First of all, the content comes from this information, which is the same as the power plant I helped build the energy supply in the Civilization Arena, but its encryption level is very high. After my sister's encryption algorithm was broken, I was able to decipher the encrypted data gradually, in small quantities. ”

"Alright, move on to the dense forest."

"This dense forest hypothesis is closely related to our tech tree problem. Do you remember when we first talked about the 'tech tree' problem? ”

Xu nodded: "Hmm." You also ask what happens if the human tech tree is crooked. ”

Duan Qing: "Yes. This information shows: Most civilizations, or should I say that the vast majority of civilizations, 99.9999% of civilizations, have a crooked tech tree. ”

"In fact, it's very, extremely difficult to have a relatively sound tech tree."

What does this mean? It's like saying that our enemies, the underwater civilizations that set off the tsunami, are mainly focused on biotechnology, which is also the technology chosen by most civilizations, or maybe a small amount of chemical technology has been added. Then, it will be difficult, or rather, incapable of continuing to develop in other directions. ”

"Physics, Mechanics, Mathematics, Information Science, Arts...... And so on and so forth, and all of this content is completely and unsourced. They can only develop on the road of biotechnology, from the first order to the second order to the third order, until they 'surpass' and reach the level of complete technology. ”

Xu Liang shouted: "Slow down a little!" Why can we only develop a certain category of technology? Why can't it be fully developed? It doesn't make sense. ”

"Because I can't be proficient." Duan Qing said, "Any science and technology is like a sea of smoke. It takes an infinite amount of effort to get into it and make a difference, and generally speaking, a civilization simply can't achieve more than one technology at the same time! ”

"It's like when I was in school, there were people in every class who were partial to Chinese, partial to mathematics, and partial to English, and the person who won the first place was probably also the first in a certain subject. But it's rare to see someone who is the first in every subject! Because you don't need to get the first in every subject to get the first overall score, and it is almost impossible to get the first in every subject! ”

"It's the same with technology, it's hard for any civilization to be proficient in all kinds of technology trees."

"That's how the tech tree works! And this is also the basis of the dense forest hypothesis. ”

Xu Liang: "Wait, there's a problem here. ”

"You say."

"It's hard, but that doesn't mean it doesn't exist. There will always be a super student who takes the first place in Chinese, mathematics, English, physics, chemistry, biology, geography, history, politics, and deserves to be ranked first in the total score, which violates the principle of science and technology tree you said, right? ”

"Of course there are exceptions, of course there are all-powerful civilizations." Duan Qing said, her expression was a little proud, "Do you know, in fact, our human civilization is such an 'accidental' existence!" ”

"We are one of the very few civilized races with an almost sound technology tree that accounts for less than 0.00001% of the number!"

"From this information, we know that most civilizations have chosen, and can only choose to develop a single technology. But for some reason...... Our human civilization is a very special exception! ”

"If you think about it, even our middle school students, those poor little ones who are less than 20 years old, have to learn seven or eight homework, and they also have to take exams!"

"This may be completely unbelievable in most civilizations!"

"This phenomenon does not exist in other civilizations!"

"We human beings are rare and well-rounded students!"

"That's what this material tells us about interestingly." Duan Qing said, shaking the small flat panel monitor in his hand again.

Xu nodded: "In other words, if a scumbag like me is in another civilization, I won't bear the name of a scumbag." ”

"Almost."

Xu Liang: "...... OKOK, what does the principle of the tech tree you mentioned have to do with the law of the dark forest between civilizations you just talked about? ”

"It's a big deal." Duan Qing said solemnly, "This directly determines the ...... between civilizations Yes and yes is a question of war! ”

"Think about it, a civilization, as long as its technology level does not break through the third order, reach the legendary 'transcendence' level, and enter the stage of omnipotence, it will receive all kinds of restrictions."

"For example, a civilization based on music, relying on music to cultivate its own sentiments can be used to enjoy and injure the enemy, but when it encounters a physical civilization that studies sound waves, it is completely finished. Because the essence of music is vibration, it must be achieved by physical means. In the same way, this physical civilization that studies sound waves must have an 'engineering civilization' that can be realized in order to turn its physical theory into reality, otherwise the flower, the mathematical language full of formula symbols, cannot be used to create products in any way. And a civilization that only knows how to build engineering, encounters a biotechnology civilization known for its material corrosion, then whatever is produced will be melted directly...... All of these examples are hypothetical, but do you understand what they mean? ”

Xu Liang understood.

This is actually what it means to descend from one thing to another. It's just that it has expanded to the cosmic level.

Duan Qing continued: "This hypothesis that the technology tree is not interoperable is actually completely incompatible with the Dark Forest hypothesis, because it means that there is no strongest civilization! Only relatively powerful civilizations! ”

"Even if a certain civilization can develop a certain technology to the third level, as long as it does not reach the 'transcendence' level, it will not be invincible. It's quite possible that there is some little-known civilization that can take it out! ”

"There is no such thing as a super civilization that can sweep away all low-level civilizations and eradicate potential threats!"

"Because every civilization has the potential to threaten other civilizations!"

"You know what it looks like? It's like a particularly dense forest! It's a super rainforest like the Amazon plain. ”

"What species do you think is strongest in that kind of rainforest?"

"Animals? Plant? Chimpanzee colonies? Ant? Piranhas? Jaguar? Neither! ”

"Because in such a forest, no one can guarantee their own safety! Even the strongest creatures may be easily killed by others in the next second! ”

"In a super-dense large forest, there are tens of thousands, hundreds of thousands, or even millions of different species! Animal, plant, bacterial, viral, protein particles...... All kinds of different classifications, all kinds of different shapes, all kinds of different ways of living...... There is no single species that can dominate the entire forest! There is no forest full of tigers, or all ants, all antwork, all anthrax! Yes, it's just brutal competition, with a relative dynamic equilibrium. ”

"In such a forest, you can't find a civilization that can kill everything, a super dense deep forest that is always in dynamic equilibrium!"

"This is the basic prototype of the law of dense forests!" Duan Qing finally concluded.

The Law of Dense Forests...... Xu Liang chewed on this term seriously and repeatedly...... At first glance, it sounds like complete. But if you think about it, if you can only click on one tech tree per civilization, it seems like ...... It's not that it can't exist?

It's like a tiger has a huge weight and a flexible body, but if it is targeted by a poison dart frog, it will definitely be poisoned, but the venom of the poison dart frog is completely ineffective for frog-eating snakes. Unless that level of "transcendence" is reached, there is only species restraint.

Seemingly, reasonable?

Xu Liang: "So according to what you said, under the law of dense forests, what should the relationship between species, no, no, civilizations?" ”

"Under the law of the dense forest." Duan Qing said, "The relationship between civilizations should be captivity. ”
