Artificial Gravity

The technology does not yet exist to create stable artificial gravity. Gravity on stations is spin gravity, while gravity on ships is tied to directional acceleration, magnetized grip pads, or spin gravity.
Artificial gravity can be generated, but it is unstable and requires a massive expenditure of energy. Unstable artificial gravity can be created (in safe containment) as a momentary impulse; as a result, it has been weaponized by manufacturers like Harrison Armory, and studies into stabilization are ongoing.
However unstable it might be, nonlethal artificial-impulse gravity is necessary to make nearlight ejections and bolts survivable for organic life.
