Planet-Sized, Non-Rotating Habitats [needs nanotech]

Just stressing: supposing that UFog is possible, then you could make
that bigger or smaller than Earth. Size would not be an issue. In
theory, you could have even a "Little Prince's Planet" for just one
person.

Another "options" ("options" is in quote marks because I don't think
seriously that they will ever be *viable* options :-) would be:

- An outer spheric grid of ultra-powerful magnets (perhaps made of
meta-stable metallic hydrogen or other sort of
magnetic/superconducting "unobtenium") that would push everything
against the inner "crust" shell through diamagnetism. Of course
ferromagnetic objects and electronics would likely be a problem under
this scenario.

- An inner black whole or chunck of quark matter in the center of the
"crust" sphere, massive enough to produce *actual* gravity on its
surface.
