Humanity is missing, luckily I have billions of clones.

Chapter 192 A little surprise

The first to move is the neutrino telescope.

Li Qingsong has built a total of 16 neutrino telescopes. The largest of these telescopes has a pure water tank storing 1000 million tons of pure water, and the smallest one has 400 million tons.

This means that the diameter of the pure water tank alone ranges from 200 to 300 meters.

It wasn't actually that big. If it was just for transportation, Li Qingsong could easily disassemble it and store the equipment parts and pure water separately, which wouldn't be difficult.

However, considering that it needs to be operated during migration, it is more troublesome.

Because the neutrino telescope has a very important feature, which is that it must shield other types of radiation as much as possible and only allow neutrinos with extremely high penetrating power to penetrate, so as to achieve the purpose of detecting neutrinos.

On the planet, Li Qingsong built it deep underground, relying on thick rock layers to achieve the shielding purpose.

In space, what does Li Qingsong rely on for shielding?

Spacecraft armor certainly has extremely high radiation resistance, but how thick does the armor need to be to achieve the shielding effect of rock layers thousands of meters deep?

Remember, neutrino telescopes require much more advanced shielding than biological organisms. Even a little more interference can essentially render the entire telescope useless.

After thinking about it, Li Qingsong decided to build an unprecedentedly large spherical spaceship.

The radius of this spherical spacecraft reaches 1.7 kilometers - so its longest point, that is, its diameter, is only kilometers. It may not seem large, but it is actually larger than the largest aerospace mothership.

Because the aerospace carrier is only 6 kilometers in length and width, but only 600 meters in height.

The internal volume of an aerospace mothership is about 18 cubic kilometers, while the internal volume of this spherical research vessel is as high as 20.5 cubic kilometers!

Its total mass also exceeds that of a fully loaded aerospace carrier, reaching about 5 million tons.

Li Qingsong placed the main structure of the neutrino telescope, that is, the pure water tank with extremely high requirements for radiation shielding, into the core of this huge spherical spacecraft, and Li Qingsong designed this spacecraft into a cargo ship.

In this way, in addition to the most core pure water tank, no matter which direction, there are armor, isolation layers, equipment with a thickness of about 1.4 kilometers, and most importantly, various materials with good radiation protection properties, such as gold, silver, copper, iron, chemicals, etc.

Using the materials to be transported as a shielding layer, a sufficiently pure environment is created for the neutrino telescope at the core, allowing it to operate normally even in space.

Because there are 16 neutrino telescopes, Li Qingsong needs to build 16 of these spherical cargo ships. And because the neutrino telescopes vary in size, working objectives, and detection directions, each spherical cargo ship needs to be specially designed.

Now that the problem of the neutrino telescope has been solved, the next step is the particle collider.

Here, Li Qingsong encountered some difficulties again.

Particle colliders can be categorized into two types: circular and linear. The circular one is easier to deal with; at most, you can just build a donut-shaped spacecraft.

But linear particle colliders are a bit more difficult to build.

It's just too long.

The longest one is 30 kilometers long!

Before this, the largest spaceship Li Qingsong had ever built was only 6 kilometers long. This had suddenly expanded fivefold. But there was nothing he could do.

It can be disassembled and transported during the transportation phase, but when it is needed for work, we can't just leave it exposed to interstellar space at a speed of a few percent of the speed of light, right?
We have to build a spaceship to carry it.

There was no other way, so Li Qingsong could only design a bamboo-shaped spacecraft again, giving it its own power and protection. He also built an equipment room, observation room, supercomputing base, personnel logistics base, etc. to accommodate this particle collider.

Because the spacecraft is so long and thin, its thrusters must be specially designed and the propulsion force must be kept strictly consistent.

Ordinary spacecraft have suitable mechanical structures, so it doesn't matter if the thruster output is slightly inconsistent, as the strength of the hull will mask this problem.

But for this "bamboo pole" spacecraft, if the thrusters are slightly inconsistent, it may break directly.

After a series of tests, improvements, and so on, and after spending a lot of effort, Li Qingsong finally solved the problem.

By comparison, those circular colliders are relatively painless.

Now that we have solved the collider, the next step is the gravitational wave detector.

Compared to particle colliders, gravitational wave detectors are more troublesome.

Particle colliders are either long or ring-shaped, and both have relatively simple structures, but gravitational wave detectors are in the shape of a figure "7".

It has a horizontal axis and a vertical axis, both of which are several kilometers long but connected at only one point.

Traditional gravitational wave detectors don't actually need an axis, they just need a few laser emitters connected to each other via lasers.

However, during this long research, Li Qingsong gradually discovered that in order to improve the detection accuracy to a certain level, even the vacuum degree of interstellar space is not enough, and it is necessary to use artificial means to create a higher vacuum degree.

Therefore, there must be a pipeline connecting these laser emitters.

Because only a solid pipe can maintain an extremely high vacuum level inside, allowing the laser to move forward without any interference to achieve the highest precision.

The two pipe axes must maintain an absolute 90-degree angle and cannot deform in any way. Once deformed, detection will be greatly affected.

Li Qingsong struggled to transport such a large and fragile detector. After experimenting with dozens of methods, he finally found a right-triangular spacecraft structure. He attached the two perpendicular pipe shafts to the right angles of the right-triangle spacecraft, ultimately solving the problem of transporting the gravitational wave detector.

After solving the environmental construction and transportation tasks of these most difficult large-scale scientific facilities, the remaining large-scale scientific projects, although also extremely complex, are generally much easier to solve.

Thus, one after another, specially customized large spacecraft were born from the dock, and high-temperature laboratories, high-pressure laboratories, array telescopes, radio telescopes, etc. were also transported into the spacecraft one by one.

At this moment, the original 30-year period will be up in a few months.

Li Qingsong's fleet has also made full preparations and can set sail at any time.

"Before I leave, I'll leave you a little surprise."

Li Qingsong thought secretly and issued another order.
