... under a vast amount of tension so as to support its own
centrifugal weight with low curvature. Punch a hole in the Ringworld
and you get Fist of God Mountain; punch a hole in a rotating colony
built of real materials and the result may be catastrophic failure.
Will the colonies be engineered with the tolerances to survive a large
impact? I haven't thought it through, but I'm guessing that it will
be safer to not put all your eggs in one basket than to try to build a
basket capable of surviving someone's nuclear option.
