I ask you to build tractors, but you build rockets?

Silence, silence is synonymous with everyone present.

David interpreted the purpose of extraterrestrial signals from a brand-new perspective. Although most of them were based on speculation, he was able to explain himself quite perfectly.

After all, no one would naively think that aliens only care about human beings and protect human development like mothers - if this is true, then there should be several miracles in history.

The core of David's energy threat theory is quite simple, and it is very consistent with the actual communication situation between the stars, and is more consistent with the inference of "human" nature led by evil.

But this inference is so terrible that people dare not believe it.

From a human perspective, once the nuclear bomb is mastered, it means that microscopic science has made breakthrough progress, which should at least represent some kind of "threshold" in the entire universe.

And what aliens would do to humans who have crossed this threshold... is simply unimaginable.

If there is really an interstellar fleet on the way, will humans have the slightest ability to fight back?

The more John thought about it, the more frightened he became, as if aliens had descended on him, squeezing him out of breath.

"This is all just speculation."

His voice was obviously shaking when he spoke, but after he said it, he became much more relaxed and his tone became firmer.

"It's not even clear whether it has anything to do with the hydrogen bomb. This is just a possible inference."

Others listened to his words as if they were grasping at straws, and nodded in agreement.

"Yeah, two signals can't mean anything."

"There may also be other unknown reasons. Maybe it's just a coincidence."

"..."

David watched everyone's reactions calmly, and after they slowly calmed down, he continued:

"The solution to this problem is very simple. More nuclear bombs are about to explode on the moon. We just need to pay attention when they explode. Those are monsters with huge yields.

If my conjecture is true, then the signal can be detected at least once more, and we will launch more Mars probes in a few months, presumably the interception success rate will be higher. "

Robert: "That's... no problem. NACA's original plan was to add two probes to Mars. After the M incident, we decided to increase it to four. It's not difficult to do this."

David: "I know, but my purpose today is not to scare you again, but to hope that you can start thinking seriously about a question from now on:

How can we survive as a civilization if things get really bad?

Should we let a few people escape, let the robots fly away with human DNA, or let them be captured without mercy? "

This time he got the answer quickly, and Claire immediately shook her head and said:

"In the next ten years, it is impossible for humans to create a spacecraft with real escape capabilities - that is, a spacecraft that can travel to other galaxies. There is no hope even within fifty years. This is a complete delusion, even if it means sending two people.

As for the second method you mentioned, let alone how we ensure that machines can find a suitable new home and resurrect humans in thousands or even tens of thousands of years, even if we can do it, it has nothing to do with us.

Escape is impossible unless aliens give us hundreds of years to develop, and I don't think NACA should even devote any resources to interstellar escape before the 1950s. "

Claire didn't say anything about escaping to other parts of the solar system. If the purpose is to survive civilization and continue to develop rather than just keeping a few people alive, it would be meaningless.

…

It was already late at night when the attendees quietly left the Presidential Palace one after another, but probably no one wanted to sleep except David.

The same was true for John. He left several of his staff behind and started a small meeting.

After all the staff were gathered, John's first words shocked people:

"Should we arrest David and put him in a mental hospital?"

Sullivan carefully observed John's expression, confirmed that the little old man was serious, and immediately admonished:

"Sir, David is one of the very few scholars with broad enough knowledge and excellent leadership skills. The Thirteenth Office is in great need of such people."

"But...but what he said...I still think that he was participating in a discussion about science fiction movie screenwriters just now. Maybe the M incident is just a very big coincidence. In fact, there are no aliens at all. In fact..."

The staff came to understand that it was not that John doubted David, but that the impact of aliens was too great, and the despair of human beings who tried their best to be unable to recover put too much pressure on him, and he was still unable to adapt to this unprecedented change.

Claire: "I know this is hard to accept but... we should trust the judgment made by the top scientists and top intelligence agencies in the United States. Every detail about this matter will be scrutinized repeatedly, and the conclusion no longer needs to be question.

And regardless of whether it is fake or not, we need to improve aerospace technology as much as possible. Maybe a slight advantage can bring different results. "

John didn't say anything, but people who knew him well knew that he recognized the other person's explanation, but he still needed time to digest it.

After a while he raised his head and asked again:

"What about escape? What should we do if the earth is to be exposed to alien cannons?"

He obviously didn't want to hear the explanation just now, and this time he asked "us" instead of "human beings".

Claire knew very well who "we" represented. It was nothing more than a small group of elites at the top. In their eyes, they basically represented human civilization.

"It's impossible to go outside the solar system. We can only find hiding spots within the solar system."

Claire didn’t think this was selfish, and she had already thought about it:

“In addition to the eight major planets, the solar system mainly includes the asteroid belt and the Kuiper belt, two dense areas of asteroids and meteorites.

The eight major planets and their satellites are all unsafe and must be important search targets for aliens. Only the outer Kuiper Belt may actually have a glimmer of hope.

Although there are no planets in the Kuiper Belt, there are many larger asteroids. For example, Neptune's satellite Triton was captured from the Kuiper Belt.

There are also a large number of meteorites with rich resources, which can provide a variety of minerals such as ice, iron, rare metals, etc., and it is very open. It is a vast area surrounding the sun with a width of more than 3.7 billion kilometers. If the potential scale is not large, it is more likely Undetectable.

I think that even for an alien civilization, it would be extremely difficult to search for a survivor gathering place that is at most the size of a meteorite in such a large area.

Although that place is also very far away from us, on the premise that we have mastered the fission nuclear propulsion technology, we are still relatively confident in spending huge resources. "
