0G
0g, or zero gravity, denotes an environment in which the effective gravitational force acting on a body is essentially zero. In practice, this occurs in orbital spacecraft and during specialized flight regimes where objects are in continuous free fall, producing weightlessness despite the presence of Earth’s gravity. The term microgravity is often used to describe these conditions, though gravity is never truly zero.
Common methods to achieve microgravity include orbital flight where the spacecraft is in free fall around
In science and engineering, microgravity enables unique observations: fluids form nearly perfect spheres, diffusion-dominated processes prevail,
Other uses of the term 0g include pre-cellular or pre-1G telecommunications, sometimes called zero-generation networks, used
