What kind of place would be the artificial planet?

What kind of place would be the artificial planet?

There are two main roads to make theoretical artificial worlds

1) Using the natural asteroids, what are colliding with each other. 

The thing is that if we would live on the artificial planet the creators of that world could select very carefully the species that would live in that world. The hypothetical creators of artificial planets that could select the raw materials that they put in those giant futuristic structures. That thing makes it possible to control things, what the people who are living in those hypothetical worlds would be under control. 

Theoretically, there are many types of artificial worlds one of them is the planet, which is formed by using the materials, which found in the solar system. Making that kind of artificial world is quite easy in theory. The only thing that the makers of that kind of huge project need are the large number of mass-drivers, which are shooting the dust and asteroids together. 

Those worlds are created by using natural materials, and the form of them is always some kind of ball. The thing is that those artificial planets would be the thing, that mankind would make in the distant future, and they can be the gate to the more complicated projects, which is far ahead of the use of the natural stones.

2) Using more refined materials like pure metals (This makes it possible to make so-called "Alderson disk") 

Another road is to use refined materials. The refined material would make it possible to make things like "Alderson disks" and ring words. The structures of those artificial words, what the futurologists are creating are far away from the natural planets. The "Alderson disk" is the so-called "pancake world", and there introduced ideas that the "Alderson disk" would ever work because the giant disk would just throw the atmosphere out from its layer. The structure is purely hypothetical, and this kind of theoretical structures are created the most brilliant brains on Earth. 

The "Alderson disk" would be larger than even the sun, but the thing is that the "Alderson disk" would have the larger gravity pool than even the entire solar system. And the thing is that the disk must rotate fast enough, that the sun would not pull the disk in it. The centrifugal force would cause the gravity on the outer layer of the disk would be crushing. 

When we are thinking about the "Alderson disk" that structure is not necessary to be very large. The size of that megastructure could be a couple of hundred meters, but in many stories, the "Alderson disk" is introduced the large, solar-system like structure. The thing is that this giant disk can be used as the giant centrifugal sling. But the fact is that the "Alderson disk" is true in the distant future. Just now we have not capacity or will to make the megastructure. 

But the thing is that the "Alderson disk" can also be covered by glass, and that thing would also make this kind of structure possible. So what if we would build the "Alderson disk". One of the thing, what makes this kind of structure interesting is that the rotation movement of the disk would allow throwing the spacecraft in the long journeys without the need to use the extra fuel. The thing is that the crew cabins on the "Alderson disk" could be in the vertical position against the rotation movement.
