Earth Era

Wei Feng did not think of this at all. ∷, no matter where the alien came from, Wei Feng would not be too surprised. After all, the universe is so big that there are countless incredible things, but... if this alien came from The solar system, from Mars, is a bit difficult to accept.

"But how could it be Mars?" Wei Feng murmured, "Mars has such a harsh environment, 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, and what happened 500 million to 600 million years ago... Who can Are you clear?"

Wei Feng was silent, and Ye Luo continued: "Although we can't be sure about this matter, in addition to the four indicators you put forward pointing to Mars, we have the most powerful evidence. This evidence is... …The technology of this alien civilization is actually not much more advanced than ours. In our speculation, with this level of technology, it is really impossible to carry out large-scale interstellar voyages. We have previously thought that Interstellar navigation may not require too high technology to explain the emergence of alien civilizations with low technology in the solar system, but don't you think this explanation is too far-fetched? On the contrary, if you think that this alien civilization has appeared in the solar system The star civilization simply came from within the solar system, so everything we face has been reasonably explained."

Wei Feng stood up with some difficulty. Before he came to the hibernation cabin again, he carefully looked at the hibernation cabin. The alien life frozen in a pale blue solid. Thoughts are like the sea under the wind: "Indeed. If they come from the inner solar system, then all the contradictions can be explained very reasonably. Not only that, we guessed that it happened in 500 million to 600 million people. The war before 2000 can also be explained... So looking at it this way, we can make the following assumptions: Before 500 million to 600 million years ago, there was a civilization on Mars, and we might as well name it "Mars civilization" "."

"The Martian civilization has developed to a level of technology that is slightly beyond 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 reasons. , they eventually became extinct and disappeared from the solar system, and then after 500 to 600 million years, our human civilization gradually emerged, 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 it was 500 to 600 million years ago. The former Martian civilization really developed to such a high level of technology, and even the footsteps have spread all over the place. The entire solar system. But why haven't we found any traces left by them in the inner solar system? If our human civilization is wiped out and another civilization emerges in 500 to 600 million years, they will definitely find our traces. , because our footsteps have spread all over the solar system, leaving our creations on almost all moons and planets. And since they have had a large-scale war, there must be a large number of debris in space, But we didn't find that either."

"I don't know." Ye Luo said, "but I have a data model to try to explain your doubts. Look."

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

A group of dense black dots flew from different planets, and then began to entangle each other in space. The small black dot obviously lost the ability to act autonomously.

"I'm simulating the situation of a space war." Ye Luo said, "This small black dot represents a battleship, and if the small black dot breaks, it means that the battleship was destroyed."

This fierce war lasted for a long time. While these little 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 severely attacked. By the end, there are few complete artifacts in the solar system, and they are almost completely in ruins.

"Look. After the war is over and there are many debris left in the solar system, some debris will fly out of the solar system because they have enough momentum, and they will never come back. Other debris will be affected by major planets. , moons, and the gravitational attraction of the sun, whose ultimate fate in the long run is to crash onto these stars."

In the simulated picture of Ye Luo projected on Wei Feng's retina, Wei Feng can clearly see this process. Ye Luo accelerated the speed of the passage of time, so Wei Feng saw that some of the black-spot wreckage quickly escaped from the solar system, and the other part of the black-spot wreckage fell on the major stars. In this way, it exists in space. The wreckage is much less.

"But there are still a large part of the debris that have stable orbits," Wei Feng said. "Based on their orbits, they will always orbit the sun or other stars stably. The reality is that we don't No debris has been found in the solar system."

"No, from a long enough time scale, such as five to six hundred million years, their orbits are still unstable." Ye Luo said, "Especially one more point, don't forget The influence of the sun. It is almost inconceivable not to attack the sun in such a large-scale war. Then you will see.”

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

"After the sun is attacked, the solar wind and light pressure will increase many times, and although they cannot affect macroscopic objects in a short period of time, if the time scale is long enough, their impact cannot be ignored. On the one hand, it is the influence of the sun, and on the other hand, the gravitational pull of the major planets pulls them like a naturally formed dust collector. As long as the time is long enough, all the debris that exists in the solar system will be removed. They either Falling into a star, or being 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 inner solar system universe."

Wei Feng thought for a moment, and then said: "There are still loopholes in this explanation. First, why is only the debris affected by this, and the rest of the tiny stars in the solar system are not expelled from the solar system? Don't forget, we were once in the solar system. Many tiny stars have been found in it. Second, the above explanations only explain the reasons for the disappearance of the debris in the universe, so what about the debris that fell on the major stars? Why do we not have it on Mars, Earth, and other stars? Any wreckage found?"

Ye Luo immediately replied: "About your first question, I want to ask you, how do you know that there was no major cleaning movement of tiny stars in the solar system due to the influence of the sun five to six hundred million years ago. It is very likely that because of the impact of the war on the sun, the sun not only cleaned up all the debris, but also cleaned up all the tiny stars. The tiny stars we observe now are just added from the outer solar system later. That's it. As for the second question... My answer is still time. 500 million to 600 million years... This time is too long, even if the wreckage is above Pluto, even if it is not affected by the atmosphere Unaffected by geological movements, and in an environment with extremely low temperature and extremely short illumination, in 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 that's why we can't find the remains of a Martian civilization... They'll all be buried for a long time."

"But...but..." Wei Feng murmured, "just like we have discovered fossils of ancient creatures, I think there will always be some wreckage that fell on the stars and just happened to be preserved due to various coincidences. Come down, right? This possibility must be very high, but why have we not even found any signs? This, this is really inexplicable."

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

Wei Feng pondered for a while, then shook his head, tossed these doubts to the back, and continued: "Although there are still doubts about this matter that we have not figured out, but come to think of it, this alien civilization came from 500 million to 600 million years ago. The matter of Mars has been confirmed at least 80%. Then Ye Luo, do you think that this Martian civilization has survived until now, and finally reached the South Gate Two Galaxy, and has some tacit understanding with the human civilization government, and then In the South Gate two galaxies, the signal "you can come over" is sent to human civilization. How likely is this situation...?"

"I think, before thinking about this question, we need to understand another question, which is... What do you think was the reason for the huge war between Martian civilizations in the first place?" (To be continued...)

ps: I have a cold... My 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 is a second one depends on the situation... Let's go to rest for a while...
