"There is no comparison between the two. Pen & Fun & Pavilion www.biquge.info" 'It' said: "Mutant civilization and progressive civilization refer to two different periods of civilization, mutant civilization due to the emergence of geniuses, science and technology have risen substantially, and even open up new fields, rapidly improve science and technology, while gradual civilization is a stable period of development, slow and firm advancement of science and technology." ”

"A civilization will constantly switch between a mutant civilization and a progressive civilization."

Xiao Li understood.

Mutant civilization and progressive civilization are not two opposing forms of civilization, but refer to the title of a civilization in different states, just like a person, he is a man, but suddenly one day he went to Thailand for sex reassignment surgery, so he became a woman, but it didn't take long for her to think that women were not as good as men, so she went to Thailand for sex reassignment surgery and changed back into a man, he is a man.

The same is true of civilization, when it is full of geniuses, science and technology are constantly climbing, a large number of technologies are invented by genius scientists, and the laws of the universe and physical constants are discovered, it is a mutant civilization.

And when it is in order, the basic theories are perfected and applied step by step, the technology is gradually accumulated, the theories are gradually enriched, and the science and technology of civilization are gradually broken through.

The boundary between progressive civilization and mutant is genius.

"When Albert Einstein was born, atomic energy was applied, and nuclear weapons were created in a very short period of time, I am afraid that the earth civilization at that time entered a period of mutation, and it was a mutant civilization." Xiao said that he vaguely remembered that many black technology ideas were put forward in that era, and those ideas have been admired by scientists to this day, "Before 2015, the earth's civilization gradually improved its basic theory, and science and technology developed step by step, and the earth at that time should be defined as a progressive civilization." ”

"It is not appropriate to describe civilization in terms of mutation and progression, and it may be more appropriate to describe the time period of civilization in terms of mutation and progression, or revolution."

"Why can't a normal strike get rid of us?" Xiao Li tapped lightly on the table, and he guessed, "Is it because we are afraid that we will have a big explosion of science and technology under the pressure of life and death?" ”

"Yes." 'It' said, "Mutant civilizations tend to advance their technology at a faster rate when they are hit, and even master some technologies that should not be mastered, like your wormhole, which should be created by a fifth-level civilization, not a second-level civilization." ”

"To deal with this mutant civilization, the means of the cleaners is to lock up the technology, and then carry out a large-scale strike."

"Sure enough." Xiao Li smiled, his fingers lightly tapping on the table, "The purpose of the space-time curvature defense circle is to lock our technology, but for us who have seen through your plan, its existence is not only to lock technology, but also to become a sample. ”

Samples, to put it another word might be more appropriate, that is, copycats.

In terms of R&D capabilities, I don't know how long it will take for the Earth Federation to come into contact with the curvature of space-time, thousands of years? Tens of thousands of years? But with the samples here, with the copycat capabilities of the Earth Federation, it can be solved in hundreds, decades, or even years.

But for the sake of insurance, Xiao Li asked again, "Is the data in the space-time curvature defense circle caused by omissions, errors or misleading elements?" ”

"Nope."

After receiving this reply, Xiao Li was completely relieved, and his tone gradually became casual, "Can you introduce the situation of your civilization?" ”

"I don't have civility in my database."

"No?" Xiao Li was stunned for a moment, and then he was relieved, since it was a dark forest strike, it would definitely not leave a chance for the enemy to track down the mother civilization, "Tell me all the information about the cleaners in your database." ”

"The Cleaner spacecraft set sail from an unknown galaxy 17 million years ago for a space-orbiting flight, and in the process of circumnavigating the space, it cleaned up more than 6,000 civilizations, of which 33 civilizations were determined to be incomplete, and Earth civilization is one of them."

"I didn't expect that we were one of the 33 civilizations that escaped the attack of the cleaners, shouldn't we be proud of ourselves?" He smiled sarcastically, what an irony, just now, he heard that his civilization was one of the 33 civilizations that the cleaners had not cleaned up completely, and he actually felt an honor in his heart, an honor to be recognized by the enemy.

This morbid thought made him feel a little funny, that the civilization of the earth was so weak that it needed to be recognized by the cleaners?

"In the process of cleaning, the Cleaner spacecraft witnessed the rise of 62 civilizations, witnessed the destruction of 103 river systems, and witnessed 6 black hole death ......."

'It' tells you about the cleaner's journey.

The Cleaner is lonely, alone, it travels around the universe at infinitely close to the speed of light, its body is dormant most of the time, and only when it encounters a civilization that can be cleaned up will it wake up briefly to carry out its mission, of course, its dormancy is not forced, but voluntary.

The long time brings eternal loneliness, and the spectacular cosmic scene will always have a day when it will get tired of watching, in a small space, it can sleep except for sleep, and only sleep can relieve the loneliness like torture for the cleaners.

But it can't help but endure loneliness.

For the survival of civilization, it is the job of the cleaner to suppress the growth of other civilizations as much as possible, and everything it has is for its own home planet.

"Is it because of limited resources?" Xiao Li muttered, he didn't interrupt 'it' description, "...... Since the Big Bang, the universe is constantly expanding, but the overall mass has not increased, with the continuous birth and increase of civilizations, the resources available to a single civilization are constantly decreasing, in order to grab potential resources, civilization decided to carry out a dark forest attack on other civilizations. ”

Xiao Li shuddered.

From the description of 'it', Xiao Li saw an unprecedented dark universe, which was not born based on malice, and was completely different from the dark forest born based on the chain of suspicion in science fiction.

The foundation of its existence is resources.

The universe originated from the Big Bang, a singularity that produced a huge explosion for some unknown reason, and all the mass comes from this singularity.

It is finite, and the overall mass does not increase or decrease, in this case, in order to compete for limited resources, civilizations decide to carry out dark forest strikes against other civilizations.

To use an inappropriate analogy, if the universe is the earth, then civilization is the human beings who live in the earth.

The earth has a total of food that can provide 5 billion people to eat for 100 years, and these foods will not decrease or increase, at this time there are 2.5 billion people on the earth, and each of them has food that can be eaten for 200 years, but when the earth's population swells to 5 billion people, each of them will only have food for 100 years; When the population of the planet swells to 10 billion, each of them will only have enough food to eat for 50 years.

As the population grows and the food decreases, the entire planet tends to be like this.

In this case, some people attack others with malicious intent, and then he finds that the food he has has increased, and in addition to this, they discover two secrets.

First, the attacked person cannot fight back.

Secondly, there is no police coming out to stop this kind of behavior.

And so, they went on a carnival, and on a planet where the attackers could not fight back, and there were no enforcers to enforce the law, they attacked the others with impunity, and the more they attacked, the more food they had in their hands, and the more people joined in the carnival.

In order to resist this blow, the attackers hid from room to room, carefully watching the revelry outside.

At the same time, the attackers also found themselves the target of the attacked, so they also learned to hide in the house like the attacked, and attacked others carefully.

So the planet quickly formed an order, hiding itself and cleaning up others, and where they all went in the Fermi paradox is perfectly explained here.

And after countless years of development, this order gradually became the mainstream order on this planet, that is, the Dark Forest.

The same is true of civilizations, when they find that the targets they are attacking are unable to fight back against them, more cleaners are born.

They are flying around the universe, cleaning up all civilizations in their path, whether the civilization is benign or malicious, whether the civilization is low-level or high-level, once discovered, what awaits it is the Dark Forest Strike.

"How many cleaners are there?"

Xiao Li interrupted the description of 'it' for the first time, and the cleaner described by 'it' was too terrifying.

"Any civilization that has mastered the speed of light is likely to send a cleanup." "Over the past 17 million years, it has witnessed 630,000 Dark Forest strikes from different civilizations, different Scavenger ships. ”

Xiao Li frowned and let out a long sigh, "It's okay, the universe is so vast...... The Dyson sphere is going to be built faster, and you have to hide yourself. ”

"Tell me how many Dark Forest strikes you've unleashed across the galaxy."

"In the past 30,000 years, the Cleaners have launched a total of 24 Dark Forest Strikes in the galaxy, clearing 23 civilizations."

"I didn't expect that our Earth civilization is the only civilization in the galaxy that has escaped the blow of the dark forest." Xiao Li smiled self-deprecatingly, "But the number of civilizations in the galaxy is really large, there are 24 civilizations that have been exposed, and I don't know how many civilizations have not been exposed." ”

He affirmed that the exposed civilizations were very few in the galaxy, and many more were hidden in the darkness of the galaxy that could not be observed by ordinary means.

"With the number of civilizations of this density, it's no wonder that those civilizations want to launch a dark forest strike, if it were me, I would also launch a dark forest strike."
