Artificial gravity (AG) requires Exotic Matter and large amounts of energy, but it can provide substantial advantages in many applications, most especially space travel. It comes in two flavors of field projector: planar and point.
Planar AG fields have two poles, and create artificial gravity that accelerates in a single direction. This can be used to counter an existing gravity field (such as floating on the surface of a planet) or to create more powerful acceleration (such as normal gravity inside a space ship). They are most commonly used in deck plating of stations and starships, but the applications are more limited by the expense and availability of exotic matter than any other concern. 0G sports fields, elevators, hovering luggage, aircars, comfortable habitats on heavy gravity worlds, the applications are nearly endless for those with the technology and an adequate supply of exotic matter.
Point AG fields are unipolar and create a spherical zone of gravity or anti gravity that behaves more like the natural gravity fields everyone is familiar with, except that the field can be projected at a distance rather than being confined to the center of the mass creating it. This type of AG field is most commonly used as propulsion, weaponry, or kinetic shielding. It uses substantially more power than planar AG fields, exponentially increasing with projection range and field intensity. Use as kinetic shielding is rare as the power requirements necessary to stop or divert high speed projectiles (and the difficulty of not splattering the crew while doing so) is problematic for most species.
