Tang Shuang doesn't discuss politics, so he doesn't answer Lu Mingyi's words.

Therefore, it is not difficult for us to foresee that any civilization with a thriving science and technology must have such a common characteristic: close communication between individuals and the elimination of prejudices, a complex and stable social structure that enables the cooperation of departments, and a strong and just government to maintain normal order. ”

Therefore, it is not difficult for us to foresee that any civilization with prosperous science and technology must have altruistic behavior in their group life, and the ultimate outcome of extreme egoism can only be isolated and destroyed, because only when altruistic behavior is widespread can a group continue to exist and continue to develop. The more abundant the resources, the larger the group, and the closer the communication, the more docile and tolerant the individual will be, and the more comfortable and effective the group life can be. ”

Therefore, it is not difficult for us to deduce that an important rule pursued by a technologically prosperous civilization is altruistic behavior. Individuals create civilizations, and civilizations reshape individuals. The most important point on this issue is that the development of civilization, especially the maturity of modern science, will make the whole society mild and non-violent. ”

Ding Feng thought that he had fully understood Tang Shuang's theory, and confidently raised his objections: "You mean that an alien civilization that can visit the earth, its entire civilization and its individuals, must be civilized and gentle, right?"

Tang Shuang: "You can say that, but there are still several issues involved. ”

Ding Feng waved his hand and said, "I don't agree with your point of view at all, just give an example to prove you wrong." ”

Tang Shuang: "For example?"

Ding Feng: "For example, there are countless times in history when two groups of people who are in the same civilization attack each other because of certain conceptual differences. ”

Ding Ji: "That's right. ”

There are too many cases in history of the party fighting against differences, and anyone who knows a little bit about history has heard of it.

Lu Yingying thought further and said: "Not only humans, but also ants, within a group, they are extremely united and highly pursue altruistic behavior, but for another ant group, they have to fight to the death." If you follow what Tang Shuang just said, this will not make sense. ”

Lu Mingyi and Wei Daqun did not speak, in fact, they also had many factual cases to refute Tang Shuang.

Tang Shuang was not in a hurry, and said to Lu Yingying: "Yingying, pour me a cup of tea, I'm thirsty." ”

Lu Yingying smiled, everyone is waiting for you to explain, and you still have the heart to drink tea!

Tang Shuang: "Whether it's the same party or ants, I want to ask everyone, why are they fighting to the death?"

Ding Feng said impatiently: "It's us who are asking you, don't always ask back." ”

Lu Yingying smiled: "Because of grabbing resources." ”

Lu Mingyi also said: "The concept is not compatible. ”

Tang Shuang: "Yes, the reason why they fight to the death is because they have a direct competitive relationship, and if there is no such competitive relationship, will there be any party that fights against each other?"

"In the entire space-time universe, we and the aliens simply don't have any resources to compete for, and the so-called partisanship is just a waste of energy. Yingying, do you think I'm right?"

Lu Yingying smiled and said, "Yes~"

Ding Ji was not very happy, this Tang Shuang dared to tease his goddess! couldn't bear it, and retorted: "No competition does not mean that we will be friendly, are pigs competing with us, aren't they still domesticated and slaughtered!"

Speaking of this, Ding Ji felt that he had grasped the crux of the problem and continued to pursue: "If you follow what Tang Shuang said, there will not be so many extinct creatures in our world, and the giant panda will not be endangered." ”

Lu Mingyi looked at him, Tang Shuang didn't speak.

Tang Shuang: "This involves the issue of ecological balance. ”

"It's a well-known fact that when an ecosystem reaches equilibrium, only one species can be accommodated in each ecological niche. Of course, humans are an exception, because with the development of intelligence, each new production technology of human beings can tap and use new resources from the environment, raising the upper limit of the size of the population. When the population size reaches this upper limit, intelligent species will develop newer technologies, find more resources from the environment, and continue to raise the upper limit of population size until they occupy all possible resources, all possible time and space, and even all possible ecological niches, leaving no retreat for any opponent to transfer. ”

"That's why animals and plants are dying out at a rapid rate as humans develop, because we have taken their ecological niches. From this point of view, we are in competition with all the animals and plants on the planet. ”

Ding Ji thought for a moment and then asked, "Then why are you sure that for extraterrestrial civilizations, human beings on Earth will not be in the ecological niche they want to occupy? Maybe human beings are the next creatures to be extinct." ”

Tang Shuang: "You asked this question well, because it involves the question I want to answer next." ”

Ding Ji: "What's the problem?"

Tang Shuang: "What are the alien civilizations invading the earth for? In other words, what is it about the earth that attracts them to come across time and space? Yingying, you can answer. ”

Wei Daqun looked at Tang Shuang amusedly, should the young man be so obviously partial?

Lu Yingying: "Water, air. ”

She's watched a lot of movies.

Ding Ji: "Mining resources. ”

Tang Shuang and Lu Yingying looked at him with your stupid eyes at the same time, human beings are trying to find ways to mine in the universe, which alien civilization has nothing to do when it is full and runs to the corner of the earth to mine minerals!

Ding Ji also realized that this answer was relatively retarded, and wanted to win back a city, and said: "Animals and plants!"

Tang Shuang praised, the young man is good, he answered correctly!

"That's right, it's animals and plants, to be exact, higher intelligent life, that is, we humans. Alien civilizations are really coming, and it's us who fancy us. ”

Lu Yingying is a good partner, and asked at the right time, "Why?"

Tang Shuang: "The rarest thing in the universe is life. We humans have been searching for so many years, but we have not found a single space life. For an advanced civilization, a completely new intelligent species, distinct from them, is of inestimable value, as they can provide strategies to break through the boundaries of logic. ”

What does that mean?

Tang Shuang: "This brings us back to the first question, scientific and technological progress! Scientific and technological progress depends on theoretical progress, where does theoretical progress come from?"

Tang Shuang asked Lu Yingying, and the girl shook her head and said she couldn't guess.

Lu Mingyi thought for a while and said, "Objective practice." ”

Tang Shuang: "Lu Lao is right, theoretical progress comes from two aspects, systematic and objective observation and rigorous and effective deduction, which is what we usually call experiment and logic. ”

"Among all the observable objective things, the phenomena of life, including human civilization, are the most worthy of observation. It's like when we look at chimpanzees, monkeys, and any other group of organisms, and by looking at them, we get data to understand the world. ”

"So, what kind of attitude would another technologically prosperous extraterrestrial civilization look at the human beings on Earth? I think they will only observe these wonders of life and civilization with curiosity, and not Captain Columbus who made a mess of this place with his barbaric atrocities. ”

……

"Therefore, even if there is a powerful interstellar civilization that can easily reach every corner of the universe and establish a galactic empire, the most likely status of the earth will be that of a civilization protected by its unique research value and specimen value, placed under covert surveillance, and excluded from the interference of foreign life, especially alien civilizations. It's like when we divide nature reserves in the jungle, limit all development, ambush cameras, and quietly observe the primates at their most natural. ”

Tang Shuang: "This is why I think that the alien civilization that can visit the earth should be civilized and friendly, not brutal and bloody in film and television dramas." ”

Lu Mingyi: "The young man is very reasonable, just like your father, he has a sharp mind and can speak well. ”

Brother Sanjian's thinking is sharp, and it is not right to be able to speak well, Tang Shuang thought to himself, the one who often said that he was going to be rude, which was strange and scary.

Lu Yingying's eyes were shining, which made Ding Ji very sad.

Shouldn't the topic of science fiction be his strong point, how did he steal the limelight by this Tang Shuang, so monkish.
