Microgravity was the state where G-forces were not quite zero, just very small. During the Galactic Civil War, microgravity was used to operate grav tubes aboard starships such as M-Class Imperial Attack Transports. Adjust the microgravity controls on the tube would allow individuals to float up or down the tube to different decks within the vessel. During the Yuuzhan Vong War, while on approach to the planet Borealis, Jagged Fel felt the microgravity was perceptibly accelerating.
