This raises the question of some interesting numbers that I don't
think we know the answer to. What are the dimensions of diamondoid
sphere(s) within which a small black holes may be contained? Obviously
this is a bit tricky -- you probably have to pin it in
place with magnetic fields or some equivalent trick.
A normal Dyson Sphere doesn't work because, like a Niven
Ring, its not strong enough to support itself against
the gravitational pull of the star. But one can imagine
a sphere that could support itself against the gravitational
mass of a planet, moon, etc. (provided you have a way to
pin it in place as mentioned). I would guess there is
a fixed relationship between the mass at the center of
the sphere and the thickness of the sphere itself.
Knowing these numbers would give us some very interesting
parameters... (I've done enough math today already).
