Artificial gravity refers to the use of technology to replicate the effects of a gravitational force. Common amongst spacefaring civilizations, it is vital aboard spacecraft and space stations to combat the muscle and bone atrophy that can result from long-term exposure to low-gravity environments.
Early technology relied on rotation to create gravity, whereas modern technology relies on spinning superconductors to generate powerful fields in limited areas. The Localized Artificial Gravity (LAG) system common throughout the United Empire of Earth (UEE) utilizes gravplating panels connected to a particle generator via a system of conduits to generate gravity on demand. In the Xi'an Empire, artificial gravity technology is especially advanced, and is so commonplace that it is used for mundane activities such as holding up tables and chairs.
