[QUOTE="Shayuri, post: 6699526, member: 4936"] In Spelljammer, physics works very differently. Any object over a specific threshold of size generates its own, full strength gravitational field once it's far enough away from a larger body, and that gravitational field is sufficient to retain an atmosphere around it in a fairly tight 'shell.' Travelers do need to have a way to refresh the oxygen within that atmosphere however. And the gravitational field is sort of two hemispheres, each of which attracts towards the effective equator of the total sphere. Which means that any ship has a plane within it that gravity 'flips' on. You pass through it, and suddenly gravity is pulling the opposite direction. This plane is defined by the sort of center of mass of the object, but extends throughout the extent of the gravitational field. So ships can sort of pick up flotsom that bobs around in the midsection of the field, out past the hull to the extent of it. It's a little wonky, but it creates a workable fantasy physics model for having ships flying around in space but retaining gravity and air without having to model pressurization and fluid dynamics and acceleration and rotation and so on. :) [/QUOTE]
