With the opening of the empire of atomic materials science branches, science and technology once again ushered in a ******, and materials science, as a basic discipline, has achieved a new development, which in turn has led to breakthroughs in other disciplines!

As the so-called foundation determines the superstructure, and the ability to create the materials you need from the perspective of atoms, the entire field of materials science has ushered in a revolutionary development, and countless new materials have emerged.

The manufacture of spacecraft has always been limited by materials, from the manufacture of aerospace vehicles in the terrestrial era, those expensive aerospace materials, to the engine, and even every screw, whether it is a vehicle inside the planet or a vehicle used for spaceflight, materials are everything that determines their fate!

The same is true in the interstellar age, the spacecraft made by the empire are getting bigger and bigger, and the mass is naturally getting bigger and bigger, so far the empire has been able to build large spacecraft with a diameter of several hundred kilometers, but at this point, scientists suddenly discovered.

If the empire still wants to build a spacecraft the size of a planet at the level of thousands of kilometers, then it must face a test, fluid static equilibrium, also known as the test of gravitational equilibrium!

The difference in load caused by the undulations of the planet's surface topography will be adequately compensated for in the deep crust and beyond. At a certain compensation depth, the pressure of the earth is in hydrostatic equilibrium, so the weight in the unit section cylinder above the compensation interface must be equal, and too much surface load will result in an equal amount of mass deficit above the compensation interface to achieve static equilibrium, and vice versa.

In layman's terms, all cosmic celestial bodies, as long as the mass reaches a certain level, then it will be affected by the gravitational balance and become a spherical shape!

Because a planet is most stable only when it is in a spherical state, why is it most stable when the planet is round?

When the mass of a cosmic body reaches a certain level, the gravitational squeeze causes the interior to melt and become lava (fluid).

The shape of the object will then be determined by the gravitational force and the repulsion between the molecules, which, although strong, will only be effective over a short distance. Gravity can act as far as infinity, but it is the weakest force.

When molecules are too far apart, gravity pulls these molecules closer to each other and squeezes them together. When the molecules get too close, the repulsive force takes effect, and it can easily overcome the gravitational pull, pushing the molecules away from each other until it is pushed far enough, and the gravitational force defeats the repulsion force again to pull it closer.

The overall structure of the planet will be adjusted repeatedly in this cycle until it reaches equilibrium, and when every part is in a state of equilibrium between gravitational and repulsive forces, the planet will become spherical!

We can blow a balloon, the binding force of the balloon plastic can be regarded as gravity, the repulsion force in the air is the same as the repulsion between the molecules of the planet, try to squeeze and pull up the balloon to see, you will see the same effect, the balloon is most stable when it is round.

The Empire's spacecraft has been manufactured at this time, both the mass of the spacecraft and its volume have reached a level, and if it is larger, it will be the same as the planet, if it is not supported by a strong keel, it will collapse and become an iron ball, not a flying machine.

Therefore, the empire will not be able to continue to build larger spacecraft until the keel technology has been improved, and the keel that can support thousands of kilometers of spacecraft will definitely require no worse materials than those used to make warp engines!

You can imagine a keel that can support the strong gravitational pull of a planet, and the material of this keel can be imagined!

But now, the empire has opened up the technology of atomic materials, and can create the materials you need from the perspective of atoms, whether you are making a warp engine, or building a spacecraft the size of a planet with a diameter of thousands of kilometers, there is no problem, and materials are no longer a condition that restricts everyone! Whatever you want!

So the empire's first real space warship used to sail the sea of stars and fight aliens was finally built, and its name was "Star!" ”

"Star" means the Empire's ambition for the universe and the sea of stars, and also means the ambition of the empire's external expansion, which is used to conquer the sea of stars!

Because the "Star" is designed to be a space-fighting ship with a diameter of thousands of kilometers and a huge planet, it was built in an already empty asteroid belt.

The asteroids in the asteroid belt have been basically cleaned up after these mining, and now the companies that make a living from interstellar mining are going to the more resource-rich Kuiper belt to mine asteroids, so the asteroid belt is very empty here, and it is used by the empire to store various smelted resources.

Choose to build here, firstly, close to the place where resources are stored, which is convenient for extracting various resources and saving the trouble of transportation; Second, it is also very close to Mars, and scientists and engineers can get here quickly;

Countless huge spacecraft have come to a void in the asteroid belt, which is far away from the various shipping lanes in the solar system, and also far away from the two huge planets Jupiter and Mars, especially away from Jupiter, Jupiter's gravitational pull is too great, and it has a great impact on the construction of spacecraft, so it must be far away from it.

A huge planet, directly dozens of kilometers long, composed entirely of smelted steel, was dragged by several large spacecraft, which was the largest of the many resource planets stored by the Empire, and these resources were usually used when building spacecraft.

The massive amount of steel needed to build the "Star", especially the keel in it, all had to be built with Qijin, which required an unknown amount of steel, so the Empire began to reduce the construction of other spacecraft and prioritized resources on the construction of the "Star".

Because the "Xingchen" is so large, there is no way to build it in the aircraft factory, and it can only be put into the void, and scientists and engineers use spacecraft to build it.

The first construction of the "Xingchen" was naturally the keel used for load-bearing, and the steel planet with a diameter of dozens of kilometers was firmly fixed in the void by three huge spacecraft with thick and long carbon fiber ropes.

Then several equally large spaceships slowly activated the internal magnetic field concentrating device, these spaceships are specially used to create atomic materials, there is no other function, only to generate a strong magnetic field, and to confine and concentrate the magnetic field.

The powerful magnetic fields inside these spacecraft are constantly concentrating on the steel planet that is being fixed, and several waves visible to the naked eye act on the planet, and the magnetic fields used to create atomic materials are rigorously calculated to pull atoms, but they cannot extract them.

Several magnetic field waves are strictly calculated, the angle and area of the fluctuation are according to the pre-set area, by the continuous action of several powerful magnetic field fluctuations, the steel planet began to undergo obvious changes, the original circular surface, the whole planet began to be slowly elongated.

It's as if when we knead the dough, we slowly stretch the already kneaded dough into noodles, to be precise, this iron planet is stretched into a stick, a thick stick!

This process is very slow and takes a long time, during which it is necessary to continuously add various other elements of metal materials to it, and at the same time, there are spacecraft dragging smaller steel planets into it.

Crafting materials from an atomic perspective is not a simple matter, and even if the empire has countless scientists, it can only do so for the time being.

This process continued until more than ten months passed, and the entire steel planet with a diameter of tens of kilometers had completely changed at this time, from the original spherical shape to a stick with a length of thousands of kilometers, and the diameter of this stick was also more than ten kilometers.

"Sun Wukong's golden hoop stick is nothing more than that!"

Scientists couldn't help but sigh when they saw the huge bones quietly placed in the void, Sun Wukong's stick is only 108,000 catties, and the mass of the stick in front of him is more than 180 million catties!

Scientists don't know how many steel planets were put into it, and the original steel was not enough to make a stick that was thousands of kilometers long and more than ten kilometers in diameter, to be exact, a keel!

If you calculate it casually, you can know that if its mass is put on an ordinary celestial body, it will definitely be affected by the balance of gravity and collapse into a huge planet, but this keel does not, it has no signs of collapsing!

Materials made from the perspective of atoms have incredible abilities, you must know that this is a kind of second only to quark materials, degenerate materials, quark materials not to mention, just degenerate materials, even neutron stars are also a kind of degenerate states!

Neutron stars are one of the few possible endpoints of a star at the end of its evolution, after a supernova explosion due to gravitational collapse. In short, a star that is somewhere between a white dwarf and a black hole when a star that is not massive enough to form a black hole collapses at the end of its life!

The material made from the atomic angle is second only to the degenerate material, it can be imagined that it is powerful, and these qualities of the keel are simply not enough to make it collapse into a planet.
