[QUOTE="Quickleaf, post: 6877584, member: 20323"] Taking a [url=http://www.nss.org/settlement/space/bernalsphere.htm]Bernal sphere[/url] for example, what would conditions on a space station be like in regards to gravity? [img]http://www.nss.org/settlement/nasa/70sArt/Bernal_Cutaway_AC76-1089_900.jpg[/img] From NASA and Wikipedia sites, I've read that some areas of the station would spin (have artifical G) and others would be stationary (zero-G). For example, the "residential sphere" would spin, and centrifugal force would simulate gravity so buildings would be constructed on the inner walls of the sphere. Would centrifugal force artificial G effectively operate like the gravity we experience? Or would there be some sort of weird curve that falling objects would experience? Within the spinning sections, there'd 1/3rd to Earth-normal G (depending on specifics) along the "equator" of the section, with diminishing G the closer one gets to the axes. A lot of the Bernal sphere designs mention Zero-G recreation areas near the axes, though it probably wouldn't be true zero-G but more like low-G, right? And my big question: What would it be like to be in the center of the spinning sphere? Imagine taking the sphere and dropping a tube from one axis to the other.
