I built the underground Noah's Ark

Chapter 27 Evaporating the Sea and Radio Silence
"Even lasers can't destroy corpses. And as long as a circuit board the size of a fingernail is missing, humans can't hide it."

Another scientist also added: "Those tall buildings are also difficult to deal with. The buildings are built according to the service life of more than 100 years. Some tall buildings were built in the last century, and they are still in good use. I think Destroying all these buildings is another difficult project.”

"I don't think this is troublesome. Humans can evaporate the seawater and get all the seawater into the sky. After the volcano erupts, it will turn into snowflakes and fall to cover these buildings." Xue Weidong, a thin natural scientist, said.

Sure enough, it was another lunatic who wanted to evaporate the sea.

"Evaporating seawater is also relatively easy. Get a few meteorites and smash them into the sea. If you add a few more, you can evaporate the seawater. If you artificially create a little acid rain, you can speed up the rate of corrosion. But, in this way As soon as it comes, Blue Star won't work well. Most likely it will be scrapped." Xue Weidong said.

This was a brainstorming session. The participating scientists thought that what they were participating in was just a purely academic discussion, so they spoke freely and opened their minds.

The ideas that come out are also bolder and bolder.

Outsiders will definitely think that this is a group of lunatics having a meeting.

Luo Ji coughed: "Live first is the most important thing. The topic we are discussing today is mainly to preserve human civilization."

Ye Linsheng suddenly said: "Can we build a big net, fish it directly in space, catch all space junk and satellites in one go, and then throw it into the ground."

Wang Defa's eyes lit up: "Young man, this is a good idea. Besides, casting nets in space is easier than casting nets in the sea. There are no hidden reefs and no whirlpools. Bring a few more nets and salvage them up and down. Row."

"No, it's useless." An old man who had been silent all this time suddenly said, "Even if all the space junk is disposed of, it's useless."

This old scientist is called Wang Yiheng, a scientist in the field of communication.

"Why? Old Wang." Wang Derong asked.

"You only think of what you can see, and other things that are invisible to the naked eye but can be detected by equipment. Such as radio waves, sound waves, light waves, etc." Wang Yiheng shook his head lightly, "The detection of aliens Once the satellite enters the solar system, the radio waves of our humans will be received by them, and humans will have nowhere to hide."

"Then is there any way?" Ye Linsheng was anxious.

Didn't expect so many problems.

Obviously, Luo Ji and Ye Linsheng still wanted to keep things simple.

If you want to hide from the sky, you need to pay attention to many things.

The difficulty is not ordinary.

"Is there a way, that is to start radio silence one year before the aliens enter the solar system. Even the time has to be advanced. After all, the preset conditions do not clearly state where the aliens began to enter the solar system."

Wang Yiheng called up a distribution map of the solar system: "If you enter the solar system from Neptune, you have to keep radio silence more than four hours in advance, so that the alien's detection satellites will not receive information."

Ye Linsheng said bitterly: "This is impossible. Only after the appearance of aliens can it be possible to keep silent. Because, before the appearance of aliens, no one would believe that aliens will come? There is no evidence, and the heads of state of various countries How is it possible to believe in such a thing as aliens? This destroys the premise."

Ye Linsheng thought very clearly that if he told the world leaders now that aliens were about to land on Blue Star.

Definitely treat yourself like a lunatic.

It is impossible to silence the radio in advance,

Ye Linsheng really felt bitter when he saw that he had worked so hard, but the final result might be in vain.

"Is there any way?" Roger asked.

Several scientists fell into silence.

After a long time, Wang Yiheng finally spoke again: "I thought of two ways. The first one is that we place several emission sources in various places in the solar system, and continuously emit strong irregular interference signals to interfere with their judgment. In this way They won't easily discover that the blue star is the mother star of human civilization."

"However, this method has a disadvantage, that is, it still tells the aliens that there are civilizations in the solar system. They may still come to investigate after a few years."

Ye Linsheng frowned: "What's the second method?"

"Then we have to predict in advance where the alien spacecraft will appear, and then we set up a signal filter or jammer in the middle to filter out or interfere with the human signal, making them think it is a natural world. noise." Wang Yiheng said.

Ye Linsheng wrote down Wang Yiheng's name again.

It seems that in order to save mankind, the scientist Wang Yiheng must be involved.

And before the arrival of aliens, enough signal jammers or filters should be deployed in space.

Ye Linsheng felt that the burden on his body had increased again.

Whether it is to manufacture space fishing nets or to manufacture jammers, huge funds are required.

And these financial pressures were all concentrated on Ye Linsheng, which made him feel like an Alexander.

It should not be difficult if the country is allowed to do these things.

However, the country will not just believe Ye Linsheng's words.

So far, there is only one person who believes in Ye Linsheng, and that is Luo Ji.

Ye Linsheng couldn't think of any way to convince more people.

"If you work hard, isn't it just to make money?" Ye Linsheng said through gritted teeth.

I have to be a little more crazy and a little more daring.

"The construction of dungeons is not that easy. You plan to use shield machines to dig dungeons underground. It's a good idea. But have you ever thought about it? There are only a few thousand shield machines in the world. And the excavation of shield machines The speed can only advance eight to ten meters in an hour. It can only dig 300 meters in a month."

"Even with full horsepower, it's only 500 meters in one month. It takes two months to advance one kilometer. It's only six kilometers in a year. How can a huge underground city be built? Moreover, how can the excavated soil be stack?"

"Even if shield machines all over the world work together, several dungeons cannot be built. And the capacity of each dungeon is limited. Even if it is calculated according to the maximum capacity, it can only hold a population of 1000 million at most. Blue 90.00% of the [-] people on the planet will die. Isn’t this ratio too disparate?” Ma Xingkong, an architectural expert, said.

Ye Linsheng couldn't help but sighed.

As soon as a master makes a move, he will know if there is one.
