Gravitational Communication

            Communication was at first limited to word of mouth, our thought trapped within in the limitations of the human busy, writing was the next step, it allowed the preservation of ideas beyond the writer’s life, and to be copied and distributed, telegraphy allowed these message to be sent faster, radio waves allowed the voices of people to be sent from one continent to another, and television a living image. With today’s ability to modify the shape of space we can send information in a new medium, by rippling space-time itself this is gravitational communication, traveling faster than light, and quietly without interference or absorption.

            Gravitational communication was made possible by the discovery that certain combinations of materials in crystalline lattices begin to transmute energy between gravity and other types of energy. This material provided the bridge that allowed not only messages to be coded into gravity but also for the transmutation of these messages back into more conventional media.

            This form of communication has generally been the solution for spacecraft, though is used in a few other applications. All spacecraft contain the material that transmutates gravity and other energies, whether it be as the driver coils inside an engine that allows faster than light travel, or in delicate sensors that allow craft to see mass distributions, or in generating there own gravity, so its use in communication was not forcing new challenges in materials handling. In fact all of the above pre-existing systems have been wired to be able to detect gravitational communication, in most small ships the large driver coils still provide the most effective antenna for gravitational communication.

            The equipment required, at its simplest is an emitter, and an antenna, these can be the same piece of equipment, as all that is required is a transmuter of energy in either direction. Communication at its simplest is a simple encoding of information digitally as a series of gravitational pulses, if the ship possesses more than one emitter it can multiplex these signal adding separate streams at different frequencies, strengths, durations etc.

            The ubiquitous nature of this material mean that first contact is always conducted by gravitational communication as it is to be sure a technology they are already tuned to. Also this communications link can be used even when ships are traveling above the speed of light, where normal optical communications tend to be disrupted, as gravity travels at much faster speeds that light, this also means messaging is nearly instantaneous.

            This form of communication does however have its disadvantages. Although the message can be beamed at the target, it is still susceptible to interception, as the transmission will travel through the recipient receiver relatively unattenuated, and continue on into space. Also the range is limited, within a few kilometers it makes a very good communications link to other craft, but with increasing distance signals have to be made stronger and baud rate reduces, as space begins to damp these vibrations.

            However the fact that all craft need only really tune existing driver coil systems to exploit this form of communication, means that it is a widespread technology, and it is really getting something for nothing.
