A week later, in the office of the Commander-in-Chief of the Interstellar Exploration Alliance. Pen "Fun" Pavilion www.biquge.info

The Commander-in-Chief and Frank sat across from each other.

"Frank, do you know why I asked you to come this time?"

"I think it should have something to do with the crisis response plan that we submitted." Frank replied.

"Yes, I've just finished discussing the crisis response plan that you and Hobart have submitted to you." The Commander-in-Chief nodded and continued, "Because your plan is too conservative, the governments have decided to use the defense plan submitted by the Hobart team to present it to the people, and your plan will be used as a supplement. ”

"Okay!"

Frank nodded calmly.

"Looks like you've already guessed the outcome." The commander-in-chief glanced at Frank and said with a smile.

"Indeed, before obtaining the super technology of the Creator World that the Future Teleported back from the Alpha Centauri system, all the current coping plans are rootless trees without a solid foundation and cannot stand the test." Frank replied earnestly.

"I agree with you, but you don't understand what the governments are most concerned about, or you do, but you don't care!"

The commander-in-chief shook his head and said to Frank in a serious tone.

"Isn't there still a plan for Hobart?" Frank replied meaningfully.

"Hobert's proposal is much more radical." The Commander-in-Chief tapped the switch on the table, and the relevant information was immediately displayed on the display.

【Inner World Construction Project】

Program Background:

Star WR104, which has become precarious after being hit by another supernova explosion, produces dazzling energy and gamma-ray bursts that could reach Earth at any time. Gamma-ray bursts are the most violent explosions that occur in the universe. The gamma-ray burst was too close to Earth, and it was facing the Earth without any tilt, and the gamma-ray burst would travel through the solar system at the speed of light with the precision of a rifle bullet. When it arrives on Earth, it can completely wreak havoc on the entire solar system like a tidal wave, and we simply cannot defend against it, and all life forms on Earth will die out without warning, and if humanity continues to live on the surface, we will perish.

According to the length of the wavelength, the electromagnetic spectrum can be roughly divided into: radio waves, microwaves, infrared, visible light, ultraviolet, Roentgen rays, gamma rays, etc., the higher the frequency of electromagnetic waves, the stronger the penetrating ability, the highest frequency of gamma rays, so its penetration ability is the strongest.

In order to ensure that the Earth's civilization can withstand the sudden attack of this gamma-ray burst, the estimated depth of the Inner World will reach more than 5 kilometers. It's really an unimaginable depth. However, on the sand star in the distant Alpha Centauri system, underground cities built by the Creator 2.1 billion years ago are everywhere, and each city is more than 10 kilometers deep.

The Creator has advanced technology that makes it easy to build the Underworld, and the Alpha Centauri Science Exploration Team has acquired the technology (white lie) left behind by the Creator!

Program Overview:

It is expected that at least 200 [Inner World] will be built in the next ten years.

The Inner World will have a complete and independently operating closed ecosystem, so that the spark of human civilization can continue to multiply.

The Inner Earth will rely on nuclear and geothermal energy to operate. (In the crustal layer, the average global geothermal gradient is 3~3.5C, so the geothermal energy around the 5km underground city will reach more than 150C).

The perimeter of the Inner World will be surrounded by a solid shell made of radiation-resistant materials......

After a quarter of an hour, Frank finally quietly finished reading the [Inner World Construction Plan] submitted by Hobart's team.

"Frank, what do you think?"

After the display stopped working, the commander-in-chief asked meaningfully.

"It does look like an exciting plan." Frank nodded in comment.

"So, do you have any suggestions?" The commander-in-chief continued to ask.

"How many people can live in 200 [Inner World]?" Frank calculated with a serious expression, "I heard that governments have been secretly building underground bunkers for a long time, but the depth of these underground bunkers is only about 1,500 meters, and it will be a huge project to build an underground city up to 5 kilometers deep." It's not much easier than building a space castle. According to my estimates, according to the current engineering construction strength of countries around the world, it is already the limit that each city can accommodate nearly one million people. Then 200 underground cities could provide shelter for up to 200 million people. ”

The commander-in-chief frowned slightly and said, "This is exactly the reason why the [Inner World Construction Plan] has not described the population that can accommodate it for the time being. ”

If the first batch of [Inner World] is completed within ten years, then who can live in it first, and what about the remaining billions of people?

Let them continue to wait as death strikes at any moment?

This will be a social problem that challenges humanity exactly.

"I understand the intention." Frank nodded, and then continued, "But will it really be safe to go to a depth of 5 kilometers?" ”

"We don't have data on the intensity of the eventual outbreak of gamma-ray bursts, so no one can answer the question of whether 5 kilometers is absolutely safe." said the commander-in-chief.

"It's true that [Inner World] can't be built too deep, and the amount of work to be built will increase exponentially with its depth. There is also the problem that the further down the geothermal energy is, the more abundant the geothermal energy will be, but too much geothermal energy will also become a problem. Construction projects cannot be carried out in extremely high temperatures, and how to cool down the underground city is also a big headache. Frank added.

"If the Alpha Centauri Galaxy Science Exploration Team can finally obtain the science and technology related to the construction of the Sand Star underground city, there may be a way to solve these problems." said the commander-in-chief.

"I'm sure they'll live up to their mission!" The corners of Frank's mouth lifted slightly, and he said very confidently.

"Hahaha~" The commander-in-chief laughed heartily, "Although, at present, the [Inner World Construction Plan] is more recognized. However, the civilization of the earth cannot afford to be all-or-nothing. Your team's interstellar migration project should also continue to work hard, and I suggest that you can solve some problems that can be solved at this stage first. For other problems, let's wait for the good news of the Alpha Centauri system! ”

"I understand, thank you Commander-in-Chief!" Frank stood up and bowed to the commander-in-chief. (To be continued.) )
