Gravity

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

• Gravity is a scientific constant.

Description (Specifications)

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

• No Gravity
• 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

History & Background (Dossier)

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.

Epochal Technological Development

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.
