All sophonts have an accustomed gravity based on their homeworld or the environment that they have spent the last year or more. Most can function with only minor difficulties at accustomed gravity plus 1/2G, and major difficulty between additional 1/2 and 1G.

Gravity, or gravitation, is a natural phenomenon by which all things with mass or energy are brought toward (...or gravitate toward) one another.

Description (Specifications)[edit]

Planetary gravity measurements have used a number of different metrics, but the following has become increasingly standard:

Gravity Benchmarks & Metrics[edit]

Gravity
Category Gs
No Gravity 0.0
Microgravity: 0.01 G or less
Very Low Gravity: 0.02 to 0.10 G
Low Gravity: 0.011 to 0.49 G
Standard or Average Gravity: 0.50 to 1.49 G
High Gravity: 1.5 to 1.89 G
Very High Gravity: 1.90 to 2.00 G
Macrogravity: 2.01 G or higher (2.01-G+)
Black Hole A Black Hole is an intense source of gravity.

Sophont Gravity Tolerance[edit]

All sophonts have an accustomed gravity based on their homeworld or the environment that they have spent the last year or more. Most can function with only minor difficulties at accustomed gravity plus 1/2G, and major difficulty between additional 1/2 and 1G. Several technologies assist in gravity tolerance: Inertial Compensator, G-Suits, Acceleration Couches and deck orientation. Examples:

  • Working crew (standing crew). Deck orientation: parallel to thrust, Inertial Compensator rating only.
  • Working crew (standing crew).. Deck orientation: perpendicular to thrust, No Difficulty: Inertial Compensator plus accustomed gravity. Minor difficulty: Inertial Compensator plus accustomed gravity plus 1/2G. Major difficulty: Inertial Compensator plus accustomed gravity plus 1G.
  • Seated crew (Workstation or Acceleration Couch) Deck orientation: parallel to thrust, Inertial Compensator rating plus 2Gs. Minor difficulty: Inertial Compensator plus 3Gs. Major difficulty: Inertial Compensator plus 5Gs.
  • Seated crew (Workstation or Acceleration Couch). Deck orientation: perpendicular to thrust, No Difficulty: Inertial Compensator plus accustomed gravity plus 2Gs. Minor difficulty: Inertial Compensator plus accustomed gravity plus 3Gs. Major difficulty: Inertial Compensator plus accustomed gravity plus 5Gs.
  • Seated crew (Workstation or Acceleration Couch) and G-suit. Deck orientation: parallel to thrust, Inertial Compensator rating plus 3Gs. Minor difficulty: Inertial Compensator plus 4Gs. Major difficulty: Inertial Compensator plus 8Gs.
  • Seated crew (Workstation or Acceleration Couch) and G-suit. Deck orientation: perpendicular to thrust, No Difficulty: Inertial Compensator plus accustomed gravity plus 3Gs. Minor difficulty: Inertial Compensator plus accustomed gravity plus 4Gs. Major difficulty: Inertial Compensator plus accustomed gravity plus 8Gs.

For accustomed gravity see Minor Non-Human Race and Minor Human Race, and for Major Races look to persons birth world.

  • Solomani Humans: Accustomed gravity is 1G. Acceleration couch and G-suit 10 minutes at 6Gs. Acceleration couch and G-suit 1 minute at 10Gs

History & Background (Dossier)[edit]

Gravity is typically conceptualized and understood by most sophont species by the end of the TL:1-3 technological epoch. By TL:4-6, gravity research becomes more theoretical culminating in prototype Gravity Control Technology by the end of TL:7-9 technological epoch.

Technological Overview of Gravity Control Technology[edit]

Technological Stages of Gravity Control Technology[edit]

  • TL:7-9: Gravity control is mostly theoretical at this stage although some society are able to create large, unwieldy gravcraft, which nevertheless work. Starcraft G-Drives become more and more capable.
  • TL:10-12: Gravity Control Technology is a foundation of interstellar period societies, which use it in large cities, for everyday transportation, in starships as Z-Drives, as scientific densitometers, and in a variety of other applications. This control of the force of gravity allows construction of vehicles, like the Air/Raft and G-Carrier, mapping of object mass through Densitometers, and safety equipment like the Grav Parachute.
    • While not often correlated by most people, historians have noted that the advent of practical fusion power plants is the result of applied gravitic compression of the fissionable fuels. Some mass-thrusters also rely on the gravitic compression of hydrogen to a near-fusion energy level. The ability to warp space-time and induce a jump is directly related to the control and understanding of gravitics. The Terran system failed to comprehend and use gravitics for many years, which delayed the Solomani expansion.
  • TL:13-15: By TL:13-15, grav vehicles merge with orbital spacecraft, making for G-Carriers with near interplanetary capabilities, a step towards becoming true system craft. Gravity assisted material technologies yield Superdense Armor, Bonded Superdense Armor, and Coherent Superdense Armor materials with protective qualities beyond anything previously imagined.
  • TL:16-18: It is expected that Gravitic Control Technology will continue to advance in the near future barring a massive apocalyptic event of some sort.
