Chapter 44: A Discussion of Life

"Haha, that's too much, it's impossible, first of all, there will be no such thing as dimensionality reduction. Moreover, you and I are both soldiers, and we both know that war is nothing but the continuation of politics, and politics is the art of compromise, and no one is stupid enough to do stupid things that both sides lose! When the war reaches a certain level, the two sides will negotiate, and it is not beneficial for anyone to lose both, it is nothing more than to find an acceptable solution. All wars on earth have always been the same, and in the end they are all compromises, during World War II, the Dunkirk retreat Nazis suddenly stopped their offensive and let 300,000 coalition troops retreat calmly, just to negotiate with Britain, but Churchill refused, he felt that the price was not enough. ”

"Since extraterrestrial beings have higher intelligence than us, intelligent beings can communicate with each other, and there is no reason why they should not understand this." Ling Moyu said.

"The law of the universe is the dark forest, and the fire of civilization is a hunter with a gun, ready to strike another civilization that appears to flicker." Liao Songcheng said.

"The law of the dark forest is premised on the fact that intelligent beings are universal, and if this condition does not exist, then the so-called dark forest does not exist. And life in the universe, especially intelligent life, is extremely rare, and may even be unique, such a vast universe only has extremely rare intelligent creatures, how can they almost never meet in the dark forest? Ling Moyu said.

"You mean, aliens won't invade Earth?" Liao Songcheng asked.

"No, it is still possible for aliens to invade Earth, but their purpose of invading Earth may be more bizarre, far beyond human understanding." Ling Moyu said.

"There is a corollary in what you said, planets suitable for the survival of intelligent beings are extremely rare, they are scarce resources in the universe, and it is reasonable for aliens to invade the earth to occupy rare resources!" Liao Songcheng said.

"Inorganic matter to organic matter, from scratch, from low to high evolution of life, and even intelligent life such planets are scarce resources, and after transformation, planets suitable for life survival are estimated to be everywhere in the universe, such as Mars in the solar system can meet the survival and reproduction of life after a certain degree of transformation. Even the moon can be suitable for living things if it has the right construction technology. With the current level of science and technology of mankind, it is fully equipped with such capabilities, but it is not economically cost-effective, and if the earth really encounters a critical moment of life and death, there is no problem at all in establishing a colony on Mars. ”

"Although the environment of the earth is very pleasant, the environment is better, more comfortable, and more suitable for biological life, but it is not necessary, and the material and energy required to occupy the earth and defeat the native race is extremely large, far less convenient than building a settlement on Mars." Ling Moyu said.

"At our current level, we have discovered many planets similar to the earth, many of which are in the habitable zone, but in fact, human space observation technology is still very primitive, and the discovered planets are just a drop in the bucket. None of these planets are very far from Earth, and even a spaceship with a speed of light of one percent can reach Earth or its vicinity within tens of thousands of years, but we have not found any evidence of the existence of aliens. When he said the last sentence, Ling Moyu was a little weak-hearted, and he subconsciously touched his wrist, which could be a strong evidence, no one knew except him.

"Then why did aliens come to Earth?" Liao Songcheng listened very carefully.

"I don't know about this either. If they come to think that the earth has something that they must get, and that the value of this thing must be beyond imagination. Ling Moyu couldn't say why.

"Generally speaking, more people believe that life in the universe is universal, and the number of intelligent beings is quite large, after all, there are too many possibilities in the universe." Liao Songcheng still didn't give up.

"The ubiquity of life in the universe is the result of people's experience on Earth, and it is a special case that only one planet with life has been found on Earth among thousands of terrestrial planets. From the perspective of probability, a small probability event will not occur, and the earth is a special case of this small probability event, since there has already been a small probability event, then another small probability event will almost certainly be zero, otherwise the small probability event will always occur or a small probability? Ling Moyu said.

"We know that the emergence and evolution of life is a long process, and there will be many difficulties and obstacles in this process, and finally from inorganic matter to organic matter, from mononuclear life to eukaryotic life, to complex life, and finally to intelligent life, every stage in this process may be a ghost gate. Once you can't get through, the evolution of life will come to an abrupt end, and there will definitely be a hurdle in this that most lives can't overcome, which is the big filter! The life forms that can escape the Great Filter are about 1 billionth of all life forms! Ling Moyu said.

"Have we humans crossed this hurdle?" Liao Songcheng asked.

"I think we are one in a billion of the lucky ones, the living environment of human beings today is still very stable, the sun is in the most stable period of his vitality, this period will last for hundreds of millions of years, the earth itself has no major geological changes, there will be no sudden disasters, these are the two most important aspects. Therefore, human beings have initially mastered their own destiny, and the remaining major disasters faced by human beings may be the impact events of small celestial bodies, which have existed many times in the history of the earth's evolution, and research has found that such disasters have a certain periodicity. ”

"You're talking about an asteroid that caused the extinction of the dinosaurs hitting the Earth, or a big explosion like the Tunguska." Liao Songcheng said.

"Yes, the current level of technology mastered by human beings can prevent such a thing from happening to a certain extent, at least to ensure that some people will survive, and human civilization will not become extinct. Asteroids that are dangerous to the earth are the key observation objects of the observatories of various countries, and once an abnormality is found, it will immediately give an alarm, and all countries in the world can take measures to avoid the impact or be sure. Ling Moyu said.

"Is it true that all small objects that pose a threat to the Earth can be monitored?" Liao Songcheng's expression became very solemn.

"Of course, not all, there may be fish that slip through the net, such as an asteroid that has been in a synchronous orbit with another and is blocked by the front one, and cannot be observed from the direction of the Earth. However, the probability of this happening is very low. Ling Moyu said.
