When the conversation ends here, Lu Yuan doesn't need to say anything else next.

This is essentially a dark forest problem.

The dark battle between these five warships is a narrow dark forest.

When each other attacks and kills each other in order to fight for possible survival resources and survival opportunities, and even there is no chance or possibility of communication and transparency between each other.

In fact, everything is already destined.

That's why the officer said it was the same.

Because this dark battle, whether he led or not, the survivors of the last dark battle have become space humans in the new era.

It completely draws a line from the humans on Earth in the old era.

Su Mei pursed her lips and looked at Lu Yuan: "So, do you think so too?"

"Wait until the day when the sun goes out."

Lu Yuan smiled and nodded softly: "What did you say?"

"But, that's right."

He said: "I didn't know my mission at first, and I thought rebirth was just a chance to start over."

"But since you have such a mission, you must do your best in the end."

"It can allow humans to have a new future after the sun is extinguished, and it can make this planetary system no longer die of silence."

"That's what I want to do now, and if I do it, I'll complete my mission."

"Everything next has nothing to do with me."

"I don't care."

"I am only responsible for this section of the road. After this section of the road, it will be the same for whoever leads humanity."

"I don't care."

Lu Yuan said calmly and sincerely. Su Mei nodded and gently pressed Lu Yuan's forehead with her fingers.

"Thanks."

"I like you like this, too."

"But." Su Mei gently scratched Lu Yuan's forehead.

"Will the sun extinguish itself be a dark forest-like blow?"

Lu Yuan stopped breathing. He actually thought about this question and thought about it many times, but when Su Mei asked him, he was still a little surprised: "Why do you think so?"

"I remember the king said that the most likely reason why the sun is extinguished is that someone terminates the sun's nuclear fusion reaction."

"But what means can end the nuclear fusion of the sun?" Su Mei looked at Lu Yuan's eyes: "I don't know, nor can I imagine."

"I can only guess it's an alien, right?"

"Why do aliens do such things? You can't just watch the sun, the star, light up here, and so you just stretch out your hand to knock the sun out?"

“Or it is part of the Dark Forest Strike.”

Su Mei said this very seriously and confidently.

Lu Yuan could only smile: "This is just a hypothesis, including the dark forest system itself, it is just a science fiction hypothesis."

"However, humans have always been good at making hypotheses on the road of science." Su Mei said: "It's like when I first studied atoms, from the original atomic model with the shape of grape cakes, to the classic nucleus and electron orbit models that are like galaxies, and to the nebula model, the birth of the principle of inaccuracy."

"Human science is achieved through repeated hypotheses."

"If the hypothesis can self-confirm the phenomena we have observed, then we will think that this hypothesis is correct until we find a way to describe the world more accurately as our understanding of the world increases."

"As for now, I really have reason to believe it."

"As for the extinction of the sun, it was also a dark forest-like blow."

Lu Yuan looked at Su Mei: "Do you still remember the reason why the Dark Forest System was established?"

Su Mei shook her head.

Lu Yuan smiled and said, "The universe is a dark forest. Every civilization is a hunter with a gun. He sneaks in the forest like a ghost, gently pushes away the branches blocking the road, and tries his best to not let his footsteps make a sound. He must be careful even when breathing: he must be careful, because there are hunters who sneak like him everywhere in the forest. If he discovers other lives, there is only one thing he can do: shoot and destroy it."

"In this forest, others are hell, an eternal threat, and any life that exposes one's existence will be quickly destroyed."

Lu Yuan was like reciting a psalm, or reciting a text. His voice echoed in this room. Then Lu Yuan smiled and continued to add: "This is the most poetic description of the Dark Forest in science fiction, but in fact, the Dark Forest itself is an explanation of the Fermi paradox."

"I won't tell you about the Fermi paradox here, but if you are interested, you can find out about it with the Transportation Commission."

"In the dark forest system, two basic axioms are: First, survival is the first need of civilization."

"Second, civilization continues to grow and expand, but the total amount of matter in the universe remains unchanged."

"In fact, this is an expansion of human development on the earth. Generally speaking, we believe that the resources of the universe are infinite, at least compared to us ants. Since they are infinite, they can be shared."

"However, compared to the infinity of humans, but not infinite compared to the two races. The origin of that science fiction is the Three-Body Civilization on Proxima Centauri. Because its mother planet is about to be destroyed, it is desperate to find a living planet that can replace it, so it found the earth."

"But if there are really countless civilizations in the universe, and each civilization will expand exponentially, no matter how huge the universe is, it will still appear insignificant compared to the mathematical game of exponential expansion."

"Then, the following conclusions are drawn."

"The first one is the suspicion chain I mentioned to you before."

"The suspicion chain itself is that both parties cannot judge whether the other party is a good-willed civilization, and the cost of communication and exploration is far greater than destruction."

"Of course, words such as good intention and malice among civilizations, and good and evil are not rigorous in science, so their meaning needs to be restricted: good intention means not actively attacking and eliminating other civilizations, while malicious intention is the opposite.

Because of the existence of the suspicion chain, it is impossible for us to determine whether the other party is good or bad at a long distance."

"And the second theory is the existence of a technological explosion."

"The speed and acceleration of civilization progress may not be consistent, and weak civilizations are likely to surpass powerful civilizations in a short period of time.

It may be caused by internal or external factors, such as communication between cosmic civilizations.

For example, the several technological revolutions led by human beings themselves, or the knowledge I brought about from my return from the future, have led to the technological explosion."
