Gravity Physics

Many of the technological innovations and linchpins of civilization in the New Diasporia Universe are based on gravity science. They will be covered in detail in following posts, or have already been covered in some detail previously. This is an overview of the most important technologies.
The Barnes-Gutierrez Hyperspace Engine is a device based on gravity science, in both its reactionless gravity drive and in its subspace shunt capability.
Likewise the Hyperdrill and Transmat Portal are devices based on gravity technology. The Hyperspace Drill not only allows a more or less permanent portal to be created between subspace and real space, but it is also capable to stabilizing real space and attenuating the gravity shear plane in subspace that prevents vessels from shunting too close to a planetary body. This allows a portal gate to be placed in relatively safe and very convenient planetary orbit, rather than a minimum of 100 diameters from a planetary mass.
Gravscanners are sensors capable of detecting the space distortions produced by gravitic devices, such as hyperdrills, contragrav, or from natural sources of gravity such as planets, stars and subspace topology.
Proximity Detectors are sensor which use gravscanner technology to detect nearby objects, such as other vehicles.
Artificial Gravity can be used to provide an isolated gravity field in a vehicle, on a platform or a building. This can be used to isolate people from acceleration effects or to protect from the effects of excessive or too little natural gravity.
Contragravity acts as a screen against natural gravity, which allows vehicles, platforms or even buildings or cities to float. In order to actually fly some sort of propulsion is necessary, typically a B/G engine.
Gravity Anchors are devices which stabilize and fix the location of a vehicle or other structure using contragravity through the use of tractor/pressor technology. A gravity anchor can also be used to hold a structure in fix position on the subspace plane.
A Tractor/Pressor beam device can be used to remotely handle objects or even vehicles through gravity manipulation. Pressor beams can be used to repulse missiles or bullets very much like a force shield, which is a related gravitic technology.
A Gravitic Multitool is a pocket device which can be used to manipulate objects, even inside other objects. It can turn screws, manipulate mechanical locks, even be used for surgery, although typically a gravitic surgical manipulator would be used for that job.
A Force Field is a field which can be used to protect a person, vehicle or other structure. The properties of a force field can be manipulated so that it will provide different levels of protection against differing threats.
