The current age of the universe is only about billion years, and it is still in the early stages of evolution. At this stage, the most abundant element in the universe is hydrogen.
Because it has not yet been processed into other elements by numerous stars through fusion.
Not to mention stars, even gas giants, more than 90% of their total mass is hydrogen.
Although this newly designed proton decay detector uses a large amount of hydrogen, it is nothing compared to the amount of hydrogen in the universe.
Li Qingsong manufactured more Jupiter aircraft and threw them into the dense atmosphere of Planet 2.
The previous Jupiter aircraft were specially used to collect deuterium and protium, while protium, or ordinary hydrogen, was filtered out. Now, these Jupiter aircraft are different. They will also bring back protium and transport it to a place about 100 billion kilometers away from Pegasus V432.
This place is far away from the star and any large planets. There isn't even a dwarf planet within hundreds of millions of kilometers around it.
This gives the place an extremely stable gravitational environment. Coupled with an appropriate orbital speed, the gravity here is reduced to a level very close to zero.
In this place, Li Qingsong built a super-large ultra-pure hydrogen separation plant.
Hydrogen from gas giants is transported here, and then undergoes a series of processes such as pressurization and concentration to finally extract ultra-pure hydrogen.
Its purity can even reach the point where there is only one atom of other elements among billions of hydrogen atoms.
While refining ultra-pure hydrogen, Li Qingsong also carried out the construction of the main body of the proton decay detector.
Under a pressure of 400,000 times atmospheric pressure, the density of hydrogen is about grams per cubic centimeter, about 70% of that of water.
According to this volume calculation, the total volume of billion tons of hydrogen is billion cubic meters.
Converted into a sphere, the radius of this sphere would reach about 650 meters.
What Li Qingsong needs to build at this moment is such a huge sphere with a radius of 650 meters.
This number doesn't seem large. However, the total height of some mountains on Earth is only over a thousand meters, and the height of the sphere that Li Qingsong needs to build at this moment has exceeded those mountains!
At the same time, mountains can be regarded as cone-like structures. And now, what Li Qingsong is building is a sphere!
Under the same height, the volume of a sphere far exceeds that of a cone.
Compared with this sphere, even the famous Mount Heng in Nanyue on Earth is completely insignificant in front of this sphere.
Countless special steel plates, countless connectors, and precision equipment from inside the galaxy converged here like a flood. Under the busy work of hundreds of thousands of general-purpose robots, these building materials were assembled little by little in space.
The action of force is mutual. In order to prevent the outer shell of this sphere from being broken by the huge internal pressure, Li Qingsong also mobilized a large number of high-strength ropes used to build space elevators, and wound and fixed them around the huge metal shell circle by circle.
After completing the construction of the main body, the next step was the most precise and difficult internal construction.
Inside this spherical shell, Li Qingsong installed a large number of magnetic field control devices to create a super strong magnetic field. At the same time, about five meters away from the inside of the spherical shell, the inner layer of the proton decay detector also began to be built.
The thickness of this inner layer is only centimeters, and the material strength is also very ordinary, and it is completely impossible to withstand the pressure of 400,000 times atmospheric pressure.
But this layer of material has two characteristics.
First, it has extremely strong resistance to hydrogen embrittlement.
Because hydrogen has a very small molecular weight, it will "squeeze" into the structure of other substances under high pressure, leading to a decrease in the strength of other substances. And this material can well prevent this from happening.
Second, it has good electrical conductivity, which means that it can be controlled by a magnetic field.
At that time, the magnetic control equipment manufactured by Li Qingsong will inject huge pressure onto it, and use it as a relay to apply pressure to the hydrogen inside.
While carrying out the construction of the detector's main body and the ultra-pure hydrogen refining plant, Li Qingsong also started the third construction simultaneously.
A nuclear fusion power plant specially designed to match it.
The newest novels are first published on !
The ultra-pure hydrogen gas that has been refined through multiple layers is injected into the inner spherical shell through special pipelines. Soon, the pressure inside the inner spherical shell rose to about one atmosphere.
The relatively soft inner spherical shell was originally a little shriveled. But at this moment, supported by the internal atmospheric pressure, it swelled up like a balloon filled with air, returning to the shape of a standard sphere, and there was no longer any depression or shriveling on the outside.
If the internal pressure continues to increase, it may be torn directly.
At this time, the magnetic control equipment arranged inside the outer spherical shell began to work.
Under the supply of huge power, based on a mode similar to magnetic levitation or magnetic confinement, the external pressure is evenly applied to every molecule and every atom of the inner spherical shell.
The internal pressure received by the inner spherical shell is converted into the pressure of the outer spherical shell.
The space elevator material on the outer spherical shell firmly binds the outer spherical shell, eliminating all pressure. At the same time, the heavy armor also blocks most of the radiation from the outside, preventing them from affecting the inner layer detection.
Under the still continuous injection of hydrogen, the atmospheric pressure inside the inner spherical shell is rapidly rising.
Five times atmospheric pressure, ten times, fifty times, one hundred times, one thousand times…
At this moment, the pressure inside the inner spherical shell is almost the same as the atmospheric pressure at the bottom of the Mariana Trench.
If a clone enters the inner spherical shell at this moment, he will be instantly crushed into meat pie.
But even though the pressure is already so huge, under the suppression of the magnetic control equipment, the soft inner spherical shell is still intact.
