The structure of the Winnie spaceship is exactly the same as what Alice said to Erdan, with a large hollow inside, and people can live freely in it." Winnie was originally a relatively small "quasi-star", or "substar", which is explained by the fact that this kind of planet has some of the conditions to become a star, and has a large amount of helium fuel, but the helium fuel reserves are not enough to make it evolve into a star that burns violently like the sun, so it is as obscure as the moon. In other words, even if it burns, helium fuel will be exhausted if it continues to burn for tens of thousands of years and hundreds of thousands of years, and it will not burn out for billions of years like the sun.

When the werewolves discovered the planet Winnie, their eyes lit up. There is no place to find it, it takes no effort to get it, and this planet can be transformed into a spaceship! It's not big, so it's easy to transform.

As they say, the Weftians have transformed the Winnie for 10,000 years, inside and out, down to the smallest detail. Of course, before the transformation, the brick house called the beast must have a deep understanding of the structure of the planet and know its structure.

For example, astronomers discovered an unknown planet 3,000 light-years away from the earth, and through guò analysis, it was found that this planet is more than three times larger than the sun; There is no one set for the smallest planets, no matter how small they are, such as the asteroid between the orbits of Mars and Jupiter, there is no shortage of fist-sized ones. Of course, asteroids are not real planets, but should be treated as planetary fragments. Planets, although they vary greatly in size, are structurally similar, and can be divided into three main layers from the surface to the inside, the outer shell, the inner core, and the transition layer between the outer shell and the inner core, which is mostly in a liquid state.

Take our lovely Earth, for example, the outermost layer is the earth's crust, with an average thickness of 17 kilometers on land and 6 kilometers in the ocean. The composition of the earth's crust is complex, various sedimentary rocks, various granitic basalts, and so on. Under the earth's crust is the mantle, which is also the thickest part, the thickness of the earth's mantle is 3,000 kilometers, and the temperature is between 1,000 and 3,000 degrees. Further inside the mantle is the core, which is divided into the inner core and the outer core, where the temperature is extremely high, the pressure is extremely high, and the density is extremely high, and the outer core may be liquid, while the inner core may be solid.

The structure of the Moon is different from that of the Earth, but it is not very outrageous, and it is divided into three layers from the inside out. Then we have reason to think that the planet Winnie is similar to this structure.

Well, figure out the structure of the planet, and start the transformation.

It is very "simple" to modify the outer part of the planet, that is, to use antimatter bombs to directly blast out the designed jet vent, which must be deep enough, a depth of several kilometers, until it touches the molten magma in the middle layer. The diameter of each spout is also very large, larger than ten football fields. After the jet port is formed, it has to be trimmed, and a nuclear reactor with magneto stone control zhì is erected at the bottom, and so on, which sounds very simple, but it is more difficult to do than to ascend to the sky, and it is by no means a one-day thing, or this is not something that people do at all.

Not to mention anything else, it is a jet port, which is difficult for us earthlings to deal with, and its difficulty is countless times more difficult than digging a Mariana Trench on the continent.

The interior of the planet is the focus of construction, but also the difficulty, after all, it is to dig a hole in the huge planet, digging a hole that can be inhabited and survived by humans. The digging of holes here is by no means a mechanical excavator or a shovel, but there are shortcuts.

The structure of the Earth was described earlier, with a surface of almost 20 kilometers thick crust, followed by a hot mantle, 3,000 kilometers thick. As for the mantle, due to the high temperature, a considerable part of it is stored in a liquid state.

The same is true of Winnie, but it is smaller, and the thickness of the mantle is hundreds of kilometers.

Hey, the volume of the earth's mantle is so large, if the liquid in it is "pumped out", wouldn't the space be enough for hundreds of thousands, or even millions of people?

Well, it does. However, "pumping" the liquid mantle out of the planet is easy to say, but it is difficult to do.

We earthlings can't do these things, but the werewolves have the ability. Here's how they usually do it: they use antimatter bombs on one side of the planet to blast one or more deep holes large enough in diameter to reach the mantle. And then the liquid in the mantle comes out under the action of internal pressure? Isn't that the case with volcanic eruptions?

It's true that the liquid mantle will emerge outward, but only a small fraction of it. It's like a volcanic eruption that can only bring out a small amount of magma, and more magma can't come out.

In order for the liquid in the mantle, that is, the magma, to be almost empty, it is necessary to "hit" the planet. To make the same analogy, if you kick a person from the back, he will definitely spit out something in his mouth, kick it once, and even vomit it after kicking it a few times.

I rub it, although Winnie is only one-third the size of the moon, but it is also more than 1,000 kilometers in diameter, what do you use to kick it? Kick in the face or kick in the ass? Can it be used well?

Wouldn't it be effective to hit it with a spaceship on another planet without using an ass or face? If it hits, Winnie can spit out "all over space" full of magma, and the core may be knocked out. If it doesn't work once, hit it a few more times until the internal magma is emptied. Magma cools quickly in space and turns into stone eggs, also known as space stones.

And how was the first spacecraft built?

This, I don't know, I really don't know, I guess it was dug out little by little with an excavator. Of course, the size of the first planetary spaceship must have been small, and even one could be built out of bricks and tiles with manpower alone. Later planetary spaceships became bigger and bigger, and then the technology matured.

It is impossible to completely drain the entire mantle, it would be nice to be able to exclude a third, and there is enough space for humans to live in it. When the interior of the emptied planet cools, it forms a criss-crossed series of solid rock "pillars" that support the shell at one end and connect to the fixed core.

If the entire hot core of the planet is eradicated, the planet hangs up and its magnetic field disappears.

So is it necessary to eradicate the planet's ball core?

The Winnie spaceship that Erdan saw in his eyes did not eradicate the ball core, but was supported by the remnants of the mantle rock pillars. There are many benefits to keeping the kernel.
