Gravimetrics
Gravimetrics is the study and mathematical science of gravity-inversion technology that allows for the levitation of devices, such as gravships. The technology originated in the Flying Islands of Jasonia as part of their plan to levitate the islands. Although much of the original science has been lost, the basic idea was that by using a fusion reactor to harness a perpetual power source, it could then energize an electromagnetic-polarization ring. The electromagnetic rings, by using the planet's own magnetic ring as a polarizer, would then provide lift to whatever vessel they were attached to. By using the amplified push of two opposing magnets, the inertia of gravity is overcome and lift is achieved. Propulsion is achieved by using a wave amplifier that can provide a controlled thrust. Thus by installing various sized thrusters along the perimeter of a vessel, such as a Gravnought, direction can be controlled during levitation.
