Inspired by a science fiction story, physicist Freeman Dyson described such a structure for the first time in a scientific paper in 1959. His basic idea consisted of an artificial spherical structure of matter built around a star at a distance comparable to a planetary orbit, with the purpose of capturing the energy radiated by the star and reusing it for industrial purposes Assume the mass of the sun to be 2.00x1030 kg Part A Consider a solid, rigid spherical shell with a thickness of 100 m and a density of 3900 kg/m.
