Earth Era

Wei Feng didn't expect this at all. No matter where this alien is speculated to come from, Wei Feng will not be too surprised. After all, the universe is so big and there are countless incredible things. But... if this alien comes from the solar system, Coming from Mars, it’s really hard to accept.

"But how could it be Mars?" Wei Feng murmured, "The environment on Mars is so harsh, there is no water, and the atmosphere is so thin..."

Ye Luo said: "Why can't it be Mars? Captain, don't forget, according to our speculation, this alien civilization may have existed for as long as 500 to 600 million years. What happened 560 million years ago... Who can Can you make it clear?"

Wei Feng remained silent while Ye Luo continued: "Although we cannot be sure about this, in addition to the four indicators you proposed before pointing to Mars, we also have the most powerful evidence. This evidence is... ...The technology of this alien civilization is actually not much more advanced than ours. According to our speculation, it is really impossible to launch a large-scale interstellar voyage with this level of technology. We have previously had the idea that Interstellar navigation may not require high technology to explain the emergence of low-tech alien civilizations within the solar system, but don’t you think this explanation is too far-fetched? On the contrary, if you think that this alien civilization appears Star civilization simply comes from within the solar system, so everything we face has a reasonable explanation."

Wei Feng stood up with some difficulty and came to the hibernation cabin again. He carefully looked at the alien life that was frozen in the light blue solid in the hibernation cabin. His thoughts were like the sea under the strong wind. General ups and downs: "Indeed, if they simply come from the interior of the solar system, then all the contradictions can be very reasonably explained. Not only that, but the war that we previously speculated that occurred 500 to 600 million years ago can also be explained. Okay... So looking at it this way, we can make the following speculations: Five to six hundred million years ago, there was a civilization on Mars, and we might as well name it "Mars Civilization."

"Mars civilization has developed to a technological level that is slightly higher than our human civilization. But for some unknown reason, an extremely huge war broke out within their civilization. Maybe it was because of the impact of this war, or maybe it was because of other reasons. , they eventually became extinct and disappeared from the solar system, and then it took 500 to 600 million years. Only then did our human civilization gradually rise, replacing the Martian civilization and occupying the entire solar system..."

"But there is a fatal contradiction in this inference, Ye Luo." Wei Feng said, "If five to six hundred million years ago, the Martian civilization had really developed to such a high level of technology, it would have even spread all over the world. The entire solar system, but why haven’t we found any traces left by them in the inner solar system? If our human civilization becomes extinct and another civilization appears in 500 to 600 million years, they will definitely find the traces left by us. , because our footsteps have spread throughout the entire solar system, leaving our creations on almost all satellites and planets. And since they had a large-scale war, there must be a large number of debris in space. But we didn’t find these things either.”

"I don't know." Ye Luo said, "But I have a data model that can try to explain your question. Look."

While Ye Luo was speaking, a three-dimensional image was projected directly onto Wei Feng's retina. Wei Feng once again saw a miniature model of the solar system, the sun, and the planets...

A dense group of small black dots flew up from different planets, and then began to entangle with each other in space. During this entanglement, these small black dots fragmented into more small black dots. The small black dot has obviously lost the ability to act independently.

"I'm simulating a space war situation," Ye Luo said. "This small black dot represents a warship. If the small black dot breaks, it means that the warship has been destroyed."

This fierce war lasted for a long time. While these small black spots in space were entangled with each other, the planets and satellites in the solar system, or those suspected to be space island bases, were also violently attacked. In the end, there were almost no complete artificial creations left in the solar system, and they were almost completely turned into ruins.

"Look. After the war ends and a lot of debris is left in the solar system, some of the debris will have enough momentum, so they will fly directly out of the solar system and never come back. The other part of the debris will be affected by the major planets , satellites, and the gravitational pull of the Sun, their ultimate fate in the long term is to crash into these stars."

In the simulated picture of Ye Luo projected on Wei Feng's retina, Wei Feng clearly saw this process. Ye Luo accelerated the passage of time, so Wei Feng saw that part of the black-spot debris quickly escaped from the solar system, while other parts of the black-spot debris fell on major stars. In this way, they existed in space. There are far fewer wrecks.

"But there are still a large number of debris that have stable orbits." Wei Feng said, "Based on their orbits, they will continue to orbit the sun or other stars stably, but the reality is that we simply cannot No debris has been found in the solar system."

"No, from a long enough time scale, such as a time scale of 500 to 600 million years, their orbits are still unstable." Ye Luo said, "especially one thing, don't forget The influence of the sun. Such a massive war is almost unimaginable without attacking the sun. Then you will see."

As Ye Luo spoke, the brightness of the simulated image of the sun suddenly increased several times. Wei Feng knew that this was what happened after Ye Luo simulated the sun being attacked.

“After the sun is attacked, the solar wind and light pressure will increase many times. Although they cannot affect macroscopic objects in a short period of time, if the time scale is long enough, the impact they can cause cannot be ignored. On the one hand, it is the influence of the sun, and on the other hand, it is the gravitational pull of the major planets - they are like a naturally formed dust collector. As long as it lasts long enough, all the debris existing in the solar system will be removed. They either fell into the stars or were expelled from the inner solar system and entered the outer solar system space. I think this is why we did not find any debris in the inner solar system space."

Wei Feng thought for a moment, and then said: "There are still loopholes in this explanation. First, why are only the debris affected by this effect, and the other tiny stars in the solar system have not been expelled from the solar system? Don't forget, we were once in the solar system Many tiny stars have been discovered in it. Second, the above explanation only explains the reason why the debris in the universe disappears, so what about the debris that fell on the major stars? Why do we not have it on Mars, the Earth, and other stars? Have you found any wreckage?"

Ye Luo immediately replied: "As for your first question, I want to ask you, how do you know that five to six hundred million years ago, there was no sweeping movement of tiny stars in the solar system due to the influence of the sun? ? It is very possible that because of the impact of the war on the sun, the sun not only cleaned up all the debris, but also all the tiny stars. The tiny stars we observe now were just added later from the outer solar system. That's all. As for the second question... my answer is still due to time. Five to six hundred million years... this time is too long, even if the wreckage is above Pluto, that is, it is not affected by the atmosphere. Unaffected by geological movements, in an environment with extremely low temperatures and extremely short light, over such a long time scale, they will gradually lose their own characteristics, and eventually merge with the planet itself, and can no longer be distinguished. Come out. The only thing that can properly preserve them is the environment in the outer solar system. I think this is why we cannot find the remains of Martian civilization... They will all be buried by a long time."

"But...but..." Wei Feng murmured, "Just like we have discovered the fossils of ancient creatures, I think there will always be some debris that fell on the stars and happened to be preserved due to various coincidences. Came down, right? This possibility must be very high, but why haven't we found even a single sign? This, this really doesn't make sense."

"I don't know about this question." Ye Luo said, "Maybe we can find the answer one day in the future."

Wei Feng pondered for a while, then shook his head, throwing these questions to the back of his mind, and continued: "Although there are still questions about this matter that we have not clarified, but thinking about it, this alien civilization came from 500 to 600 million years ago. The matter of Mars can be confirmed at least 80%. So Ye Luo, do you think that this Martian civilization has survived until now, and finally arrived in the Nanmen II system, and has some tacit understanding with the human civilization government, and then How likely is it to send a signal to human civilization in the Nanmen II system that "you can come here"?"

"I think that before thinking about this problem, we need to think about another question first, that is...what do you think was the reason for the huge war between Martian civilizations?" (To be continued ~^~)

PS: I have a cold... My whole body is sore, my head is dizzy... I feel like a rainbow... I'm afraid I won't be able to survive this winter... Whether there will be a second update depends on the situation... Let's go and rest for a while...
