An Artificial Planet

An Artificial planet, supported using dynamic orbital rings above a small planet-mass singularity (a black hole)
from the Orion's Arm Scenario

The original idea came from Paul Birch of the British Interplanetary Society.

[kemmerer]

The ecology and climate on such a world would resemble a CELSS, that is a Contained Ecological Life Support System. The carbon cycle in particular would be truncated. Artificial planets would only be built where there are no suitable planets for terraformation; or perhaps, where extra planets are desirable in a system which already has a terraformed world.

[kemmerer]

Well, yes; the majority of mass in a planetary system is hydrogen and helium, not much good for making solid planets unless you have cheap transmutation. With this system H and He can be added to the black hole until your planet is as large as you wish. Additionally the planet need not be limited to an Earth-like size; using the black hole as a gravity generator, an artificial planet with 1 gee surface gravity could be much smaller, or much larger.

If you can control black holes, who the fk needs to construct a planet? apart from the Magratheans of course.

[kemmerer]

The difficult part isn't controlling the hole, it is making the hole in the first place. They are difficult to create because they are so small and evaporate so fast. Once you manage to get the hole past a certain mass (about the mass of a small asteroid) they accept mass much more easily, and then you just add any old rubbish until the hole masses as much as an Earth-sized planet. After that you can use the hole as a gravity generator. The hole can be used as an energy generator too.

i doubt if that planet has enough matter for enough gravity to allow us to walk on that planet.

[kemmerer]

No, the planet itself is hollow, but the centre of the world contains a 1 centimetre wide black hole which provides all the gravity required.

Good thing you didn't add copyright material to your video so that in 4 million years when we need a new planet, we can still know what to do.

There used to be a laser fusion device called SHIVA where multiple laser beams in a spherical array fired simultaneously on a deuterium pellet to cause a fusion reaction. Perhaps some day in the future a monster version of SHIVA may be able to create, sustain, and reliably confine a micro black body. Wouldn't be surprised if someone somewhere was already doing it. :)

STOLE MY IDEA!!! Ah, well. Hey, what if you sliced one of the rings?  BOOM!

[SailorBarsoom]

Hey, I had a thought.

Any reason the mass at the center has to be a black hole? Suppose you got to another star system and you found a Jupiter-clone, only in the habitable zone. Could you build a shell around it, far enough from the planet itself that you get a bigger-than-Jupiter "planet" with Earthly surface gravity? Couldn't you do the same with a superterrestrial planet, or perhaps even a brown dwarf?

@razorx71 The point is the surface area.

[DereenigneEsrever]

@JoF00l The weird thing is that anything inside a hollow planet would be weightless since the gravities of all parts of the crust would cancel out at every point of the interior.

[razorx71]

So its like a planet.. but no self sustaining eco system, no self sustaining climate system, no resources.... whats the point? If you can create a black hole, you can terraform a real planet.

how create stuff in celestia
