Say a sufficiently advanced civilization (ETI? OA in 100K?) builds a ringworld around a 1 million  LL⊙ LBV. If I remember the ringworld formula and statistics right the edge is spinning at 770,000 km/...

Thanks How long does it take in the Eleventh Millennium AT to make a McKendree Cylinder? An hour? A day? A week?

1) Stability Would Banks Orbitals be significantly more stable than Ringworlds if, for some reason, maintenance were temporarily interrupted? I know Ringworlds are unstable in the short term. 2) Pop...
