The last human in the universe

Chapter 109 Ignore
At this moment, even if scientists have powerful observation equipment unprecedented in the history of civilization, they will be unable to find that nebula at all.

Zhuang Yunwei's judgment was supported by a considerable part of the evidence in the face of this iron-like fact.

So……

Zhao Changxing looked at the civilization that was already at the edge of the outer solar system. It had developed for nearly 700 years, had a population of more than 660 million, and a civilization with a space fleet composed of more than [-] soldiers.

It is strong but weak, prosperous and decaying.

But no matter who it is, they can easily draw a conclusion.

It is impossible for the human civilization at this moment to fight against a powerful civilization that can span the long distance between the stars and come from afar.

Boundless despair is like an ocean that drowns people.But Zhao Changxing still looked calm, and he didn't seem to have any negative emotions.

"Wait for further analysis."

The cluster of nebulae lit up for a little over three days.During most of these three days, people used the most powerful observation equipment they could use to aim at it, trying their best to obtain all kinds of information contained in it.

At this moment, a large team of scientists is analyzing the data.

Five days later, Zhuang Yunwei, chief scientist of the Academy of Military Sciences, came to the human government building again.

Today, he will report to all high-level human beings headed by Zhao Changxing, including all members of the Civilization Management Committee and the War Committee.

"According to our analysis, we believe that if the ion thrusters that 'lit up' this cluster of nebulae are really ion thrusters, then the fleet we speculate most likely does not exist. If it does exist, it is more likely It's a spaceship. Yes, only one."

Zhuang Yunwei described his own evidence in as straightforward a language as possible.

"First of all, the coordination of different regions is too consistent. It's like this fleet is completely the same whole, accelerating and decelerating at the same time. There is no delay between multiple parties. Considering the communication delay caused by the distance between each other, this This action is extremely difficult.

Second, even if they can do the above, then their forward trajectories are also highly coordinated, which is not easy to explain.After all, it is a nebula, and its constituent substances will inevitably have random effects on different spacecraft, causing deviations in its course.But we didn't observe that either.

To sum up, we are more inclined to think that there is one spaceship. "

This obviously means more stuff and more information.

The first thing people feel about this is shock.

A spaceship, just a spaceship, lit up a nebula with a range of more than one billion kilometers?
How big and how powerful does it have to be to do this?And how powerful is the technological strength of a civilization that can manufacture such a spaceship?
Zhuang Yunwei continued: "According to the information obtained from the deep space civilization, we already know that the Moyun Litar civilization has mastered the energy source method of 'matter and antimatter annihilation' which is far more efficient than nuclear fusion. Based on this, we assume that The average unit area, the ejection power of the ion thrusters manufactured by the Moyun Litar civilization is an order of magnitude higher than ours, and then calculated based on this, substituting the ejection power received by this nebula, it is calculated that the spaceship The ejection area is at least as high as 10 square kilometers."

10 square kilometer!

This number made all the high-level civilizations who heard the report stagnate.

You know, this is just the ejection area of ​​the ion thruster!And it is obvious that it is impossible to have only one jet in the design of the spacecraft.Therefore, the area of ​​10 square kilometers must be scattered.

So, how much tail area is needed to accommodate the scattered spray area of ​​10 square kilometers?

According to the current human spaceship design, it is at least 200 square kilometers.Even though Moyun Litar's technology is relatively advanced, there is still a limit.

Comprehensive consideration, its tail area may be between 80-120 square kilometers.

If it is a square, then its area is about 9 kilometers by 9 kilometers to 11 kilometers by 11 kilometers.

This has not counted its length.

如果它具备9*9到11*11的底部面积，长度有个20公里，不算过分吧？

Such a huge spaceship, just thinking about it, will make people feel desperate.

"Another point to note is that if the jet direction of this spacecraft is facing our galaxy, then it is obvious that this spacecraft is in the process of decelerating at the moment. As for why it is decelerating, I don't need to say more .”

The atmosphere in the conference room became more and more serious.

Why slow down?It must be finally parked in the solar system.

Zhao Changxing is thinking quickly at the moment.However, what he was thinking about was not about the technology and power of this spaceship, but another matter.

He tapped lightly on the table, attracting everyone's attention.

"I'm curious, the Moyun Litar civilization only sent one spaceship, what is its purpose?"

Zhao Changxing's words aroused people's deep thinking.

Does the Moyun Litar civilization believe that human civilization can be wiped out with just one spaceship?
Everyone here is certain that the answer will not be that simple.

The first point is that the Moyun Litar civilization has the ability to detect traces of the existence of intelligent life in the solar system in the Laland 21185 galaxy, which is several light-years away, and roughly analyze its technological level.

The method is also very simple, as long as the spectrum of the earth's atmosphere is analyzed when the earth is transiting the sun.

Standing in the Lalande 21185 galaxy to observe the sun, when the earth moves between the two galaxies, the sunlight will only reach the Lalande 21185 galaxy after passing through the earth's atmosphere.The changes in the Earth's atmosphere caused by the sun's rays can reveal the elemental composition of the Earth's atmosphere.

By analyzing this point and analyzing the content of some trace elements, such as hydrogen sulfide, it is possible to basically confirm whether there is intelligent life on this planet.If so, what is the approximate technology level?

Or, if the technological strength of the Moyun Litar civilization is strong enough, even if there is no transit, they can also directly observe the sunlight reflected by the earth's atmosphere to draw this conclusion.

In short, the existence of human beings cannot be concealed.

But at the same time, the Moyun Litar civilization will not regard human civilization as an opponent at all.Even at this moment, the most intelligent people in the entire civilization are thinking about how to fight them.

Because human civilization is simply not qualified.

They would think that the process of the black hole swallowing the sun is enough to completely destroy such a backward civilization.Even if a few survivors reproduced occasionally, so what?
Human civilization in its heyday can be destroyed with a wave of hands, so how many survivors are there to be afraid of?
Therefore, it is not that the Moyun Litar civilization is too arrogant, so arrogant that it thinks that just sending a spaceship can destroy human civilization.More likely, they don't care about human civilization at all.

They ignore human civilization.

This spaceship is simply here for "mining".

This is a mining ship, at most an armed mining ship.It is not a professional combat spaceship.

Perhaps it is because the resources of the Lalande 21185 star system have not been digested and absorbed, but the minerals that exist in the black hole accretion disk are needed at the current stage. We set up a mining spaceship to collect some of that kind of minerals and take them back for emergency.

This is what happens.

"This is our chance."

Zhao Changxing pointed out this point.

Zhuang Yunwei lowered his head and thought for a moment, then said again: "Even if it is a mining spaceship, I don't think we, our fleet, can defeat it."

"But our enemy has at least changed from an entire civilization to a spaceship, hasn't it?"

This is a fact.But another fact is that for jumpers, there is no difference between jumping from a 100-story building and jumping from a 20-story building.

"Professor Zhuang, can you analyze, if it is indeed a spaceship, how long will it take for it to reach our solar system?"

"We have relevant data." Zhuang Yunwei quickly flipped through the documents in his hand, and said, "According to the luminosity change data of that nebula, we roughly calculated its deceleration rate and current speed. The conclusion is that it is about 12-18 After 8.2 years, it will pass Sedna's orbit around the sun. At that time, if its heading remains unchanged, it will probably pass by a distance of [-] million kilometers from us."

"Is it possible that this mining spacecraft flew directly to the vicinity of the sun to start mining minerals, completely ignoring us and ignoring us?"

Zhao Changxing said in a low voice: "If it were me, I wouldn't like a bug flying beside me when I was working."

Zhuang Yunwei said: "Even if it ignores us, so what? You know, the main body of the Moyun Litar civilization will come sooner or later. They are a wandering civilization. After digesting the resources of the Laland 21185 galaxy, they must go to the next A star system. Since you go everywhere, why don't you come to the solar system?"

Zhao Changxing knocked on the table again to stop people from discussing.After that, he looked at Zhuang Yunwei: "Professor Zhuang, I hope you can imagine the future development of science and technology, and roughly divide the different civilizations that may exist in the universe into one level according to the level of technology and strength. Can it be done? "

Zhuang Yunwei said: "Scientists in the earth age have already done this. The Kardashev index is."

Zhao Changxing shook his head: "This is too general. I want to be more detailed. I want to know what are the iconic technologies of different levels of civilization, what kind of capabilities they have, how big is the scope of activities, and how far has the basic theory reached? .”

"it is good."
