Re: "Real" ringworlds
I thought that Dyson Spheres were inhabited on the inside like a Ring World, but completely encompass the sun to trap all energy and possiably hide from the rest of the universe (wasnt it a Star Trek movie that found a bunch of Dyson Spheres?).
*sigh* too bad we have to mess around on this rock of a world instead of going out to the "Last frontier"
