According to the data stated in this document, it took them 3,000 years to travel from the solar system to the South Gate II system. According to this time, the forward speed of a spacecraft propulsion using the black hole engine is only a few hundred kilometers per second. And this speed is no different from a snail crawling compared to a long interstellar voyage.

When Wei Feng saw this, Ye Luo's voice appeared in Wei Feng's ears again: "Captain, I think there are some contradictions in the description in this information. ”

Wei Feng staggered his gaze away from the information, then looked at the place where Ye Luo's voice came from, and said one word: "Oh? ”

"I think the contradiction is this." Ye Luo said, "Since this information says that their spacecraft that use the black hole engine as the propulsion method can be qualified for the needs of interstellar navigation, and it is only hindered because it is too slow, then...... This means that their ships have sufficient, long-term survival capabilities. Although the sun has gone berserk under their attack, I don't think the sun can affect a place 10 billion kilometers away. So...... Why aren't they looking for a foothold in an extra-Neptune object? In this way, they will have a safe environment and an abundant source of material, as long as they multiply slowly, they will sooner or later be able to restore the population, and then slowly develop technology. ”

Ye Luo described a possible way out for the Martian civilization at that time: with Xena, Sedna and other extra-Neptune objects as material sources, survival depends on the life support system of large spacecraft, and survival is guaranteed. Slowly develop the population. Slowly restore technology. This looks like a viable path. But...... At that time, the Martian civilization did not choose to take this path.

"I think I know why the Martian civilization didn't choose to go this way." Wei Feng said slowly, "Actually, even if our human civilization were to face this situation, our human civilization would probably not choose this path. ”

"Why? I don't understand. Ye Luo said.

"Of course you won't understand." Wei Feng said a little lonely, "You ignored one point, that is...... Technological civilization will not only move forward, it will also degenerate...... As described in this material. Their population is less than 10 million people, and even if 10 percent of those 10 million people are scientific researchers, the number of scientific researchers is 1 million. So I ask you...... One million researchers in our human civilization...... Is it enough to pass on our technology? ”

"It's clearly not enough." Ye Luo immediately said, "With the scale of our human civilization with hundreds of billions of people, as well as the science and technology we have accumulated in the past thousand years, if we want to develop these technologies, no, not to talk about development, only to talk about inheritance." At least billions of researchers are also needed. Technology has advanced to the point where we are, and its branches are too detailed. This is far from being something that a few people can afford. ”

"So the Martian civilization will inevitably face the threat of serious civilization degradation. If you choose to stay in the extraterrestrial Neptune object, it will be fine at first, but with the passage of time, with the death of the few remaining scientific researchers, the Martian civilization will face various dilemmas: no one will repair the spacecraft if it breaks, no one will install the parts, and even if it does, no one will make it when the spare parts run out...... When their reserves are depleted, how do you want the Martian civilization to survive in that cold region away from the sun? …… In fact, I think that the Martian civilization was already facing this dilemma when the escape plan was implemented, and I think that the spaceship they used to escape was probably made before. When the escape plan began...... They no longer have the ability to build such large ships. ”

Ye Luo was silent for a moment, and then retorted: "This can indeed explain the reason why they didn't stop at the extracelestial body of Neptune, but Captain, even if they finally reach the South Gate Two Galaxy, they will still face the threat of civilization degradation." In the South Gate II system, no one will repair their ship, and no one will build it when they run out of parts. ”

"But there's another inexhaustible source of energy." Wei Feng said, "There are stable suns there, and there are two of them. Obtaining and utilizing solar energy is a very simple matter, and I think that even if it is degraded, it will not be difficult to master solar energy, right? ”

"But there is also a sun in the solar system...... Not. ”

Ye Luo only stopped halfway through this. Wei Feng sighed: "There is indeed a sun in the solar system, but ...... At that time, the sun was already angry, and it would take at least tens of millions, if not billions, of years for its anger to calm down. And in the face of an angry star...... And what civilization would dare to approach it? ”

"Well, I have to admit, Captain, you're right." Ye Luo said, "The only way for them to survive is to sail to the South Gate II, use the two calm suns there to obtain energy, and then survive and slowly recover their population and technology." ”

"In fact, I think that this is not the only reason why the Martian civilization chose to sail to the South Gate II." "There is probably another reason...... Again, you won't understand this reason. Because it's about emotions. If a civilization is compared to a man, then ...... Suppose this person is trapped in a room for many, many years, when he is on the verge of death...... Will he make the decision to "even if he dies, he will go and see what the outside world is like"? ”

Ye Luo asked, "Even if this decision is not so wise?" ”

Wei Feng replied calmly, "Even if this decision is not so wise. ”

Ye Luo said, "Okay, I understand. But...... I have one more question. With the technology of our human civilization at the moment, it is enough to create a spacecraft with a speed of up to 3,000 kilometers per second like the Xinghai spaceship, why is the spacecraft made by the Martian civilization, which is more technologically advanced than us, only a few hundred kilometers per second? If it is true that black hole engines can only reach such a small speed, then why don't they choose traditional nuclear fusion propulsion technology, but choose black hole engine propulsion technology? ”

Wei Feng shrugged his shoulders, and then said, "The Xinghai spaceship made by our human civilization has a speed of up to three thousand kilometers per second...... How many people can it carry? ”

Ye Luo immediately said, "One." ”

Wei Feng continued to shrug his shoulders: "So do you think that the expedition spacecraft of the Martian civilization may only carry one person?" Their ship, a ...... Why do you have to carry tens of thousands of people. ”

"Oh, I see, the black hole engine as the propulsion method of the spacecraft has huge thrust, and it can also provide a steady stream of energy for a long time, it is suitable for super giant spacecraft, although its speed is slow, its technical content is still less than the thrust, but the fast Xinghai spacecraft is advanced. Just ......"

Ye Luo stopped talking after saying the word "just", and it seemed that the terrible scene that continued behind these two words made even his intelligent program feel palpitations.

Wei Feng also didn't ask what it was, and it seemed that Wei Feng also knew about it. But Wei Feng didn't say anything, but still read this information.

In the previous document, it was reported that the runaway fleet of the Martian civilization split again after a period of exile, some of them still insisted on sailing, and the other part turned around and planned to return to the solar system. Next, Wei Feng saw such a description.

"Unfortunately, just as our ship had just slowed down to almost a relative standstill relative to the Sun, the ship's propulsion components had suffered a terrible malfunction...... And this kind of failure is beyond our reach. Our ship lost its propulsion and remained forever at a distance of trillions of kilometers from the sun, unable to move forward or backward. ”

"I sent a distress signal to the rest of our Civilized Fugitive Fleet, but none of them were willing to return to rescue us. Well, spare parts and energy are invaluable to every ship, and what ship would give its resources to save us? ”

"Although the tiny black hole is still providing us with energy, it ...... In this vast and barren cosmic space, this energy will always run out one day. So I went into a long hibernation, and before hibernation, I left instructions for the intelligent program that controlled the spacecraft, and I gave it the permission to disassemble the spacecraft itself to replenish the mass of the black hole when it had decreased to a certain extent. I hope that before the energy to sustain my hibernation runs out...... Someone can save me, although I know that this wish is too elusive and basically impossible to fulfill. ”

"Those ships that return to the solar system will inevitably be destroyed, and all passengers will die, and the ships that continue to sail to the South Gate II system...... If they're lucky, they should be able to reach their destination before the ship finally breaks, but even if they do, I'm not optimistic about their fate. With too few people and too few tools, it's a long journey to a completely unfamiliar galaxy to survive...... Easier said than done. ”

"That's what our Martian civilization is going through. We are born out of this universe of nothingness and eventually destroyed in this universe of nothingness, as if we had never been in this universe. ”

"I hope you're looking at this at the moment...... Remember us, remember this little civilization that once appeared in this small solar system. We are a Martian civilization, and on behalf of our Martian civilization, I wish you the best of luck. ”

This information is over, but Wei Feng is still looking at it in a daze. Halfway, Wei Feng suddenly said, "This Martian is hiding a lot of things. ”

Ye Luo said: "It's already over, why bother to pursue it?" (To be continued......)

PS: Hmm, ask for a monthly pass again......
