The last human in the universe

Chapter 164 The Abyss
In this way, people have finally avoided the inevitable "scum" problem of digging this "big pit".

Those plasmas that are responsible for blowing away the "scum" can also be regarded as working fluids from another perspective.It is obviously impossible to transport such a large amount of working fluid from the orbit around the No. 3 planet.But people chose to use local materials.

The supporting fusion power plant will also generate a lot of waste heat during the power generation process.This heat, in addition to heating the temporary living base built here, will have a lot of surplus.

Originally, people would have chosen to discharge the waste heat directly onto the asteroid.But now, they have a better place to go.

When the knives on the disk cut rocks, a part of the rocks will be collected by the automatic collector, and then transported to the fusion power plant, responsible for cooling the fusion reactor.The process of cooling the fusion reactors is, in turn, the process of heating them.

So they turned into plasma, and then ejected from the air outlet, blowing their "companions" into space.

In this way, no additional working medium is required.

This is a more advanced engineering design.

At this moment, looking at the thick beam of light that appeared out of thin air from above the deep ground, Zhang Longfei felt slightly moved.

He knew that some of the rubble blown out of the asteroid would break free from the gravity of Lakai 9352 and enter the interstellar space.But there are also some that have not achieved such a high speed.

They will form a smaller version of the "asteroid belt" orbiting the star.

This reduced version of the asteroid belt will have a total mass of about 4 million tons.

Because what people want to dig is a super long channel with a length of up to 44 kilometers.All the substances that originally constituted this channel will be blown into space.

The excavation period for this channel is ten years.This also means that, on an average day, about 15 tons of matter will be blown away by this giant machine built by people, either in the form of plasma or in the form of solids.

Zhang Longfei was suspended in the space for a while, and then he clearly saw with the naked eye that the huge disc-shaped machine sank a little downward.After one day passed, all the machinery fell into the ground.After waiting for a month, it has sunk hundreds of meters underground.

A year later, it sank 4.4 kilometers underground.Ten years later, it has been running continuously for ten years, and it has never stopped running for a moment. Even when it is overhauled, it just shuts down one of the modules, and finally stops running.

Excavation then turned, and people began construction work on the level, using the remaining facilities.Finally, a huge underground cavity with a height of 100 meters and a length and width of one kilometer was excavated.

At this moment, Zhang Longfei, who had been working here for nearly ten years, finally let out a long sigh of relief.

He knew that building a dark matter detector, and by the way a neutrino telescope, was the most important part of the job.

Yes.This probe will be built in the center of the asteroid.The thick layers of rock that make up the asteroid will be the heaviest shield against other types of radiation.

This shielding strength is unprecedented.Because on a large planet, it is impossible for people to dig a space 44 kilometers underground.Because the gravity of the star itself will cause it to collapse inevitably, and even at this moment humans have not yet developed super materials that can resist this force.

So after research, people set their sights on the space, on the asteroid with extremely small gravity, and finally selected it.

Hence, the ten-year-long excavation task of hundreds of millions of tons of material came about.

Later, more and larger transport spacecraft began to descend on this planet.More construction workers began to work in the space located in the center of the earth, installing various life support, living and scientific research facilities there in a gravity-free environment.

These include a smaller roller base, a gigantic tank filled with pure water, and numerous giant computers.

The subsequent transport spacecraft transported away the construction personnel, leaving behind the scientific researchers responsible for the subsequent operation and use of this dark matter detector.

In the 19th year after the first industrial spacecraft arrived here, the largest and most precise dark matter detector in the history of human civilization was put into operation.

Zhang Longfei reluctantly left here and went to the next battlefield.

There, there is also a similar facility that needs him to preside over the construction.

However, the difference here is that the main observation target of another facility is the star Rakai 9352.It mainly observes neutrinos from this red dwarf star, and tries to study the interior of this red dwarf star through the observation of this extremely penetrating particle, so as to obtain more scientific details about the star.

This is still of great significance to the overall scientific development of human civilization.

Because the main target to be observed is neutrinos from this star, this neutrino telescope must be built as close as possible to this star.The reason is simple, the farther away from the star, the lower the density of neutrinos and the lower the efficiency of observation.

But this also faces the problem of requiring a shield of sufficient thickness.At this moment, there are no asteroids near the star.However, human civilization does not have enough technological strength to directly push a qualified asteroid to the past.

The shield can only be found on the No. [-] planet closest to the star.

Planet No. 9352 has been locked by Rakai [-], and will only face this star with one side forever.For this planet, the time of day and year are equal.

One thing that is counterintuitive to most people is that although Planet 9352 is gravitationally locked, it is actually located in the habitable zone of Rakai 29.Its side facing the star has an average temperature of only about [-] degrees Celsius, just enough to maintain the existence of liquid water.

Moreover, there is a huge global ocean on it, whose water volume exceeds twenty times that of the earth's ocean.

Sitting on the spaceship heading to Planet No. [-], Zhang Longfei was full of thoughts, and couldn't help but recall the scene when he participated in the feasibility discussion meeting.

"Planet No. 20 is too massive and has too much gravity. The neutrino telescope must be built extremely deep underground to eliminate interference as much as possible. We have reduced the requirements as much as possible, but this depth must also be reached More than [-] kilometers."

"We don't have enough technology to dig a depth of 20 kilometers on such a huge planet. Even if we can dig it out, our materials can't maintain its existence."

"This is not feasible. I suggest that this project be temporarily postponed. We will build it after we have sufficient technological strength."

"No, the study of the internal mechanism of red dwarfs is extremely important. To put it a little higher, it is related to the fate of our civilization!"

Zhang Longfei at that time was also troubled by this problem.He is very aware of the significance of this task, but he is even more aware of the difficulties faced by this task.

Finally, an idea was born in his mind.

"I remember...the ocean of Planet One, the deepest part is 21 kilometers deep..."

Water of sufficient thickness can also become a qualified shelter.

Zhang Longfei's words, an inspiration, brought the construction task that was almost on the verge of extinction to life.

Although on this planet, the "Abyss" - this is the name people give to the deepest seabed, the water pressure there is as high as 3.2 times the water pressure of the Mariana Trench on Earth, which is more than 3400 times the atmosphere The pressure is enough to crush almost all common objects in people's lives, but in comparison, building an engineering submarine capable of resisting this pressure and building a neutrino telescope base on the seabed is always better than building a neutrino telescope base here. It is many times easier to dig a 20-kilometer-deep tunnel on a planet.

So Zhang Longfei came.

Looking at the huge planet under his feet, which is half dark and pale, and half bright blue, looking at the white cloud clusters and the huge typhoon visible to the naked eye covering the bright half of the sky, Zhang Longfei showed a smile on his face.

A special air-space shuttle left the transport ship and began to descend downward.After going deep into the atmosphere for a certain distance, Zhang Longfei keenly felt that the spaceship he was on experienced some turbulence.

The further you go down, the more severe the bumps will be.Later, it even gave him a feeling of riding an off-road vehicle on the uneven surface of the planet.

But this space shuttle ship is specially made, and a stabilization module against extreme weather in the atmosphere is specially added, but the result is still so bumpy.

This is enough to prove how violent the external hurricane is at this moment.

When the space shuttle was suspended less than a hundred meters away from the surface of the sea, under the light of bright red stars, he really saw the scenery that belonged to this planet.

At this moment, there are only two words in his mind.

Strong winds, huge waves.

That is based on the grading standard of the earth era, at least a strong wind of level 16.It was a huge wave that could even be called a tsunami, with a height of tens of meters.

This forced the pilot of the spacecraft to raise the hull by tens of meters to avoid the fate of being directly smashed into the sea by huge waves.

At this moment, a thought was born in people's hearts at the same time.

"Compared to the ocean here, in the documentary, how docile the ocean on Earth was..."

At this moment, the hull of the spaceship was raised by more than 100 meters again.

Zhang Longfei felt a little puzzled, he didn't know why.He looked at the display screen in front of him, clicked a few times, and found the reason.

An undersea volcano erupted, causing a tsunami.In another ten minutes, the 136-meter-high waves, which are almost unimaginable by humans on earth, will sweep across this sea area.

At this moment, the sky did not know when it also began to become dark.Thick clouds obscured the sun.Accompanied by a lightning that was many times thicker than the earth, it was really like a downpour, no, an unknowable amount of heavy rain was pouring down than the downpour.

Storms, thunder and tsunamis.At this moment, this place is like hell.At this moment, even this space shuttle, which has experienced countless space journeys and is manufactured with the most advanced technology of human civilization, can't stand it anymore.

"Because of the changing weather, we will evacuate urgently now. Please sit tight and fasten your seat belts..."

In front of the prestige of heaven and earth, the air-space shuttle fled.The first exploration operation was over before it started.

　I wipe, what's the situation. . .I set a regular update for this chapter, which should have been updated yesterday. . .Why update today to see if this chapter is still there. . .

　　I wiped it, it was broken yesterday. . . .just found out...

　　Well, this chapter was yesterday and there is another chapter today
