The first thing to be relocated was the neutrino telescope.
Li Qingsong had built a total of 16 neutrino telescopes. The largest of these telescopes had a pure water tank inside that stored 10 million tons of pure water, and the smallest had 4 million tons.
This meant that the pure water tanks alone were 200 to 300 meters in diameter.
Relocation wasn't actually too difficult. If it was just transportation, Li Qingsong could completely disassemble them, storing the equipment parts and pure water separately, which wouldn't be too hard.
But considering the need to keep them running during the migration voyage, it became more troublesome.
Because neutrino telescopes have a very important characteristic: they must shield as much of other types of radiation as possible, only allowing highly penetrating neutrinos to pass through, in order to achieve the purpose of detecting neutrinos.
On the planet, Li Qingsong built them deep underground, relying on thick rock layers to achieve this shielding purpose.
In space, what would Li Qingsong rely on for shielding?
Spaceship armor certainly has extremely high radiation resistance, but how thick would the armor need to be to achieve the shielding effect of thousands of meters of rock?
Don't forget that neutrino telescopes have much higher requirements for shielding layers than living organisms. A little bit of interference would basically render the entire telescope useless.
After thinking about it, Li Qingsong decided to build an unprecedentedly massive spherical spaceship.
This spherical spaceship had a radius of kilometers—thus, its longest point, the diameter, was only kilometers. It seemed small, but it was actually larger than the largest aerospace carrier.
Because aerospace carriers only had a length and width of 6 kilometers, but a height of only 600 meters.
The internal volume of an aerospace carrier was about 18 cubic kilometers, while the internal volume of this spherical research ship was as high as cubic kilometers!
Its total mass also exceeded that of a fully loaded aerospace carrier, reaching about 500 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, at the core of this massive spherical spaceship. Moreover, Li Qingsong designed this spaceship as a cargo ship.
In this way, outside the most core pure water tank, in any direction, there were about kilometers of armor, isolation layers, equipment, and, most importantly, various materials with good radiation protection performance, such as gold, silver, copper, iron, chemicals, and so on.
Using the materials to be transported as the shielding layer created a sufficiently pure environment for the neutrino telescope at its core, allowing it to operate normally even in space.
Because there were 16 neutrino telescopes, Li Qingsong needed to build 16 such spherical cargo ships. And because the neutrino telescopes varied in size, working objectives, and detection directions, each of these spherical cargo ships needed to be specifically designed.
After solving the problem of the neutrino telescopes, the next was the particle collider.
Here, Li Qingsong encountered some difficulties again.
The shape of particle colliders can be divided into circular and linear. The circular ones were easier to handle; at worst, he could just build a ring-shaped spaceship.
But the linear particle collider was a bit difficult to deal with.
It was too long.
The longest one was even 30 kilometers long!
Before this, the largest spaceship Li Qingsong had built was only 6 kilometers long. This was an expansion of five times.
But there was no way around it.
It could be disassembled and transported during the transportation phase, but when it was time for it to work, he couldn't just let it be exposed to interstellar space at a speed of a few percent of the speed of light, right?
He had to build a spaceship to装 it up.
There was no way, Li Qingsong could only design another bamboo pole-shaped spaceship, making it self-propelled, protective, and even building equipment rooms, observation rooms, supercomputing bases, personnel logistics bases, and so on, to accommodate this particle collider.
Because this spaceship was too long and too thin, its thrusters had to be specially designed, and the thrust had to be strictly consistent.
Ordinary spaceships, because they have suitable mechanical structures, it doesn't matter even if the thruster output is slightly inconsistent, the hull strength will shield this problem.
But if the thruster propulsion of this "bamboo pole" spaceship was slightly inconsistent, it might just break.
After a series of tests, improvements, and so on, it took a lot of effort for Li Qingsong to solve this problem.
In comparison, those ring colliders didn't cause much trouble.
After solving the collider problem, the next was the gravitational wave detector.
Compared to particle colliders, gravitational wave detectors were even more troublesome.
Particle colliders are either long and narrow or ring-shaped, with relatively simple structures. But gravitational wave detectors are "7"-shaped.
It has a horizontal axis and a vertical axis. Both axes are several kilometers long, but they are only connected by one point.
Traditional gravitational wave detectors actually don't need axes, they just need a few laser emitters connected to each other by lasers.
But Li Qingsong gradually discovered during this long research that if he wanted to increase the detection accuracy to a certain level, even the vacuum of interstellar space was not enough, and he had to use artificial means to create a higher vacuum.
Therefore, there must be a pipeline connecting these laser emitters.
Because only a solid pipeline can maintain an extremely high internal vacuum and allow the laser to travel forward without any interference, in order to obtain the highest accuracy.
These two pipeline axes must maintain an absolute 90-degree angle, and they must not undergo any deformation. Once deformed, the detection will be greatly affected.
Such a large and fragile detector gave Li Qingsong a headache. After experimenting with dozens of methods, Li Qingsong finally found a right-angled triangular spaceship structure, installing the two perpendicular pipeline axes on the two right-angled sides of the right-angled triangular spaceship, which solved the transportation problem of the gravitational wave detector.
After solving the environmental construction and transportation of these most difficult large scientific devices, the remaining large scientific devices, although extremely complex, were much easier to solve.
Thus, one custom-built large spaceship after another was born from the shipyard, and high-temperature laboratories, high-pressure laboratories, array telescopes, radio telescopes, and so on were also transported into the spaceships one by one.
At this moment, the originally scheduled 30 years was only a few months away.
Li Qingsong's fleet was also fully prepared and ready to set sail at any time.
"Before leaving, let me leave you a little surprise."
Li Qingsong thought secretly and issued another order.
