Toroidal planet in scifi art - Cray - 11-22-2020 Moonbow by Rick Sternbach: RE: Toroidal planet in scifi art - stevebowers - 11-22-2020 That's nice! It resembles the Hoopworld which I described in the Oracle War article, and the Hoopworld was itself based on some calculations by Grant Hutchison which were intended to describe a toroidal planet with the same rotational period as the Earth. Grant has noted that a Hoopworld would be less stable than a donut world like Torus, and would quite quickly separate out into spherical globules. But presumably both the Terragen Archai and whoever built this Moonbow have a remedy for that problem.
