Editing Gravity

[[File: Imperial-Sunburst-Sun-Scouts-wiki.png|right|125px]]
[[Gravity]], or gravitation, is a natural phenomenon by which all things with mass or energy are brought toward (...or gravitate toward) one another.
* It is also a standard [[Third Imperium|Imperial]] [[metric]].
* ''Gravity'' is a [[Science|scientific]] constant.

== Description ([[Specifications]]) ==
Planetary gravity measurements have used a number of different [[metric]]s, but the following has become increasingly standard:
* The common [[Third Imperium|Imperial]] abbreviation is ''G''.

=== Sophont Gravity Tolerance ===
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 Couch]]es 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 Race]]s 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]]) ==

=== Technological Overview of Gravity Control Technology ===
* Theoretical Gravity Control ([[TL:7-9]]) → [[Gravity Control Technology]] ([[TL:10-12]]) → Advanced Gravity Control Technology ([[TL:13-15]]) → Very Advanced Gravity Control Technology ([[TL:16-18]])

=== Technological Stages of Gravity Control Technology ===
* '''[[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-Drive]]s 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-Drive]]s, as scientific [[densitometer]]s, and in a variety of other applications. This control of the force of gravity allows construction of [[vehicle]]s, like the [[Air/Raft]] and [[G-Carrier]], mapping of object mass through [[Densitometer]]s, 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]], [[Gravcraft|grav vehicles]] merge with orbital [[spacecraft]], making for [[G-Carrier]]s 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.
