Wei Feng didn't expect this at all. No matter where this alien came from, Wei Feng would not be too surprised, after all, the universe is so big, and there are many incredible things, but ...... If this alien is from the solar system, from Mars, then it is really a bit difficult to accept.

"But how could it be Mars?" Wei Feng muttered, "The environment of 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 that according to our speculation, this extraterrestrial civilization may have existed for as long as five to six hundred million years, five or six hundred million years ago...... Who can say for sure? ”

Wei Feng was silent, and Ye Luo continued: "Although we can't be sure of this matter, in addition to the four indicators you put forward earlier point to Mars, we have one of the most powerful evidence. This proof is ...... The technology of this alien civilization is not much more advanced than ours. And in our speculation, with this level of technology, it is unlikely that a large-scale interstellar voyage will be launched. We have thought that interstellar voyages may not require too high technology to explain the emergence of low-tech alien civilizations in the solar system, but doesn't this explanation feel too far-fetched? If, on the contrary, it is believed that this extraterrestrial civilization simply came from within the solar system, then everything we are facing is justified. ”

Wei Feng stood up with some difficulty, and once again came to the front of the hibernation cabin, carefully looking at the hibernation cabin. This alien life is frozen in a pale blue solid. His thoughts fluctuated like the sea under a storm: "Indeed. If they simply come from within the solar system, then all the contradictions can be explained very reasonably. Not only that, but the wars that we speculated to have taken place five to six hundred million years ago can also be explained...... In this way, we can speculate that there was a civilization on Mars five to six hundred million years ago, and we might as well name it "Martian civilization". ”

"The Martian civilization has developed to a slightly more technological level than our human civilization, but I don't know why. There was an extremely huge war within their civilization, perhaps because of the impact of this war, or because of some other reason, they finally became extinct and disappeared from the solar system, and then after five to six hundred million years, our human civilization gradually emerged, replacing the Martian civilization to occupy the entire solar system......"

"But there is a fatal contradiction in this inference, Ye Luo." Wei Feng said, "If it was five to six hundred million years ago. The Martian civilization has really developed to such a high level of technology that it has even spread all over the solar system. But why haven't we found any traces of them in the inner solar system? If our civilization goes extinct and another civilization emerges in five to six hundred million years, they will surely find our traces, because our footsteps have spread all over the solar system, leaving our creations on almost all moons and planets. Also, since they had a large-scale war, there must have been a lot of wreckage in space, but we didn't find any of that either. ”

"I don't know." Ye Luo said, "But I have a data model that I can try to explain your doubts. You see. ”

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

A dense group of small black dots flew up from different planets, and then began to entangle with each other in space, and in this entanglement, these small black dots shattered into more small black dots, and those small black dots after breaking obviously lost the ability to act independently.

"I'm simulating a space war situation." Ye Luo said, "This small black dot represents a battleship, and the small black dot is broken, which means that the battleship is destroyed." ”

The war lasted for a long time, and while these little black dots in space were entangled with each other, the planets and moons in the solar system, or what seemed to be the base of the island in space, were also violently attacked. In the end, there are almost no complete artificial creations left in the solar system, and they are almost completely in ruins.

"Look. After the war is over, there are many debris left in the solar system, and some of the wreckage will fly directly out of the solar system and never come back because they have enough momentum on their own. The other part of the wreckage will be attracted by the gravitational pull of the planets, moons, and the sun, and in the long run, their ultimate fate will be to crash into these stars. ”

In the simulated picture projected by Ye Luo on Wei Feng's retina, Wei Feng clearly saw this process. Ye Luo accelerated the speed of time passing, so Wei Feng saw that part of the black dot debris quickly escaped from the solar system, and the other part of the black dot debris fell on the major stars, so that there were many fewer debris in space.

"But there is still a significant part of the wreckage that has a stable orbit." "Judging by their orbits, they will always orbit the sun or the rest of the stars, and the reality is that we have never found debris in the solar system at all. ”

"No, their orbits are still unstable on long enough time scales, say five to six hundred million years." Ye Luo said, "Especially one more thing, you don't forget the influence of the sun. In such a massive war, it is almost inconceivable that there would be no attack on the sun. Then you see. ”

As Ye Luo spoke, the luminosity of the sun's simulated image suddenly increased several times. Wei Feng knew that this was the situation after Ye Luo simulated the sun being attacked.

"After the sun is attacked, the solar wind and light pressure increase many times, and although they cannot affect macroscopic objects for a short time, if the time scale is long enough, the impact they can cause cannot be ignored. On the one hand, the influence of the sun, and on the other hand, the gravitational pull of the planets - they are like a natural dust collector, as long as long enough, all the debris that exists in the solar system will be removed, and they will either fall into the stars, or be expelled from the inner solar system and into the outer solar system space. I think that's why we haven't found debris in the outer solar system. ”

Wei Feng thought for a moment, and then said, "There are still loopholes in this explanation. First, why is it that only the wreckage is affected by this, and the rest of the tiny stars in the solar system have not been expelled from the solar system? Don't forget, we've found many tiny stars in our solar system. Second, the above explanation only explains the reason for the disappearance of the debris in the universe, but what about the debris that fell on the major stars? Why haven't we found debris on Mars, Earth, or the rest of the stars? ”

Ye Luo immediately replied: "Regarding your first question, I would like to ask you, how do you know that five to six hundred million years ago, there was not a single large-scale cleaning campaign for tiny stars in the solar system due to the influence of the sun? It is very likely that because of the impact of the war on the sun, the sun not only swept away all the debris, but also all the tiny stars, and the tiny stars we observe now are only added from the outer solar system later. As for the second question...... Again, my answer is timing. Five to six hundred million years...... This time is too long, even if the wreckage is on Pluto, that is, it is not affected by the atmosphere or geological movements, and the temperature is extremely low and the light is very short, in such a long time scale, they will gradually lose their identity, and eventually merge with the planet itself, and can no longer be distinguished. The only thing that can properly preserve them is the environment in the outer solar system. I think that's why we can't find the remains of the Martian civilization...... They will be buried for a long time. ”

"But...... But......" Wei Feng muttered, "just as we have found fossils of ancient creatures, I think there will always be some wreckage that fell on the stars that happened to be preserved by various coincidences, right?" It must be very likely, but why haven't we even seen the slightest sign of it? This, it really doesn't make sense. ”

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

Wei Feng pondered for a while, then shook his head, threw these questions behind him, and continued: "Although there are still doubts about this matter that have not been clarified by us, but thinking about it, the fact that this alien civilization came from Mars five to six hundred million years ago can be confirmed at least eighty percent. So Ye Luo, do you think that this Martian civilization has survived until now, and finally arrived in the South Gate Two Galaxy, and has some tacit understanding with the human civilization government, and then sends a signal to the human civilization in the South Gate Two Galaxy, "You can come over", this situation ...... How likely is it? ”

"I think there is another issue that we need to understand before we think about it, and that is...... What do you think was the reason for the great war between the Martian civilizations in the first place? (To be continued......)

PS: Got a cold...... My whole body is sore, and my head is dizzy...... Rainbow Feeling...... I'm afraid I won't be able to survive this winter......

Whether there is a second depends on the situation...... Let's go and rest for a while......
