Build that Megastructures 05 Shellworlds [this video] - it will help to set gravity to normal one where living surface will be. Or make your tools 2 times stronger - kinetic energy of falling water glass will be just 2 times bigger then normal (hm although it's expected to break in normal gravity). Main problems will be humans, they could be reinforced with tech, without changing they human nature.

A Shell World. [this video] As Isaac Arthur explains in his video, you can build it as big as you want and the amount of filler material is proportional to the surface area, so its density goes down as the size goes up. You use one megaton of matter per square foot of surface, for Earth-normal gravity. You could have a thick crust with fake geology and places to mine things. It's not until they develop advanced technology that they will detect that the world is hollow and has a dynamic support structure under the crust, just as we figured out the insides of Earth. They may be puzzled when developing theories about planet formation and long-term state, though. On Earth, note that for most of histo

You need a megastructure, not a solid planet. See, in particular, shellworlds . [this video] As I recall, the basic idea is to build a shell using dynamic structures [LINK] for structural integrety and support, rather than ordinary matter. This is covered over to give a shell. The actual mass inside the shell is whatever is needed to get the desired gravity. I suggest watching Isaac Arthor's YouTube series on megastructures.

This might not be what you meant, but probably the best option for creating a livable surface on a gas giant would be a shell world [this video] . As explained in the video this is an active support structure enclosing the gas giant at the radius where gravitational acceleration is equal to Earth gravity.

I like your original [LINK] formulation more, as it shows some of your thoughts about such construction. a) Prevent Collisions You can build this structure on the moon itself. If you build it in lower or higher orbit it will take ages for a collision, to happen if any. There is a lot of space between planet and moon where such construction will be perfectly fine. Build it in the same orbit as the moon, but on opposite side of the Earth. It will need some positional corrections, but as far as materials go, it should be not a problem. (Do it same way as you would haul materials to the moon-station.) b) Power Solar power is not a bad choice actually, since you are primarily concerned about inte

50 years * I'm the scientists. Technology itself is not so complex, just stack piles of dirt on top of each other. It is that [LINK] simply and same way the pointless use of matter. You could do billions of space habitats from that mater for people to live, and wasting all those matter is almost a crime. But if you wish comic look you have to address that question to designers, and if you do wish just a look, not the mass then you even do not need a mad scientist for that. Just make a big sphere and cover it with dust and purchase moon look design. If you need moon look and moon mass then Mars can be used to make about 8 moons. If you ok with moon look, and moon gravity, but 2-10 times bigge

Consider a type of constructed megastructure such as a shell world [this video] . Each layer is like a floor in an apartment building, and some levels are set up to appear like a natural “surface” planet, but it’s really an ellaborate terrarium. Most of the shape of the mountains and seas are molded into the floor. Since this is inside , what to do about the sun? The sky is the ceiling of the level, which could be many miles up. It is a rich display screen which fakes the appearance of stars etc. and programs in a display of the daily sun, with its seasons. Only something got messed up in the software, or maybe the zookeepers were feeling like a creative experiment. For whatever reason, the param

Assumptions: The usable mass of the solar system is 2x10 30 kg (as mentioned by @Alexander) and is completely converted the materials used to construct the sphere. This includes the sun which forms 99.86% of the known mass of the solar system. We are building a Death Star-like structure, consisting of internal rooms, rather than a Dyson Sphere or a Hollow Earth shell. The structure is made of rooms with average dimensions 10m x 10m x 5m including the wall/ceiling/floor thicknesses The walls/ceiling/floor average 1m in thickness and are made of some hollow graphene structure (honeycomb/tuned composite nanostructures/etc.) with an average density of 1720 kg/m 3 (the density of the C 60 fullere
