Grasers
GraserA graser is a device capable of projecting a coherent beam of gravitomagnetic energy, in a similar manner to how a laser can project a coherent beam of electromagnetic radiation. The gravitomagnetic radiation emitted from a graser consists of phase-correlated gravitophotons, analogous to the phase-correlated photons emitted from a conventional electromagnetic laser. Grasers have a variety of applications ranging from gravity tethers to high-powered energy weaponry.GRASER is an acronym for GRavitophoton Amplification via Stimulated Emission of Radiation, and is a gravitophoton analogy to a laser. In normal electromagnetic lasers, a solid, fluid or plasma is charged with an energy of any varying sort. This energy can be electrical, thermal, chemical, etc. Due to quantum mechanical considerations, particles (electrons, in most cases) in the substance reach a higher energy level and immediately begin to seek stability. These particles quickly release quanta of energy so as to self-stabilise. Because of the common material composition and common energetic stimulation of the crystal lattice, the photons released form a coherent beam of electromagnetic radiation, powerful enough to be capable of seeing applications ranging from barcode scanners to advanced weaponry. Grasers follow a similar principle. However, instead of a fluidic or gaseous gain medium, a rotating set of superconductors is used to generate a gravitomagnetic field. Note that the rotation of the superconductors is self-sustaining because of the asymmetrical coupling constants of gravitophoton pair production, which is how energy and momentum extraction from the vacuum is accomplished. The only energy which needs to be supplied to the weapon comes from the energy required to power the cooling lasers which keep a supply of liquid nitrogen sufficiently cool to allow a superconducting state. Energy is also needed to actually fire the weapon, though because of the aforementioned regenerative effect of energy extraction from the dark energy field, this energy is very quickly regenerated. Grasers fire via a mechanism analogous to a laser. When the rotating superconductors are in their ground state, the gravitomagnetic field generated is only strong enough to sustain their continual rotation and consequent imaginary vector potential. When firing, however, the principle of stimulated emission is used: The superconductors are injected with electromagnetic energy. When flooded with photons, the gravitomagnetic field begins to transform the normally electromagnetic photons into gravitomagnetic gravitophotons, leading to a vast increase in the power of the beam via the aforementioned energy extraction from the vacuum and increase in coupling constants associated with gravitomagnetism. Because of the common stimulus and composition of the superconductors, the beam of
gravitophotons released from stimulated emission are phase coherent and extremely focused. Gravitophotons are unique in that they mediate the gravitomagnetic interaction, meaning that they can interact with and exhibit properties of both electromagnetism and gravity. Additionally, the gravitomagnetic coupling constant nearly identical in strength to electromagnetism, meaning that gravitophotons produce similarly-powerful electromagnetic interactions as photons but vastly (by a factor as high as 10^42) stronger gravitational fields than those normally exhibited by traditional matter. This equates to a gravitophoton beam being able to transmit approximately the same thermal energy of normal photons but the kinetic energy of what would normally require an extremely large (planetary) gravitational field.Note that the gravitophotons emitted can be of either the gravitationally-attractive species or the gravitationally-repulsive species. The coupling constants in the two types of gravitophotons generated during pair production (attractive and repulsive) are different because of mathematical considerations from Extended Loop Theory, meaning that the two particles produce differently-powerful distortions of spacetime. The repulsive gravitophoton of positive energy is extraordinarily weak, barely interacting with matter (it's coupling constant is 10^-18 G, where G is Newton's gravitational constant) any more than dark energy does. The attractive one, however, is a completely different entity despite being simply a different species of the same overarching particle type, having a coupling of nearly 10^42 G (again, due to mathematical considerations from Extended Loop Theory). The attractive particle is consequently almost always used in practical applications because of its vastly higher coupling strength. The repulsive particle has some applications, however, it's decay into quintessence particles and consequent essentiality in inertial mass reduction (and consequent faster than light travel and communication) being a prime example. Grasers can act as weapons or as tools for gravity tethers, gravity emitters, Subspace drives, etc. When used as weapons, the pulse of photons is short and energetically peaked such that it transmits a very destructive jolt of thermal and kinetic energy to a target, transmitting both a destructive pulse of heat and destructive pulse of kinetic energy to a target. When used as tools for gravity emitters, however, a gentler, lower frequency pulse of photons is used over a much longer pulse duration to generate the gravitomagnetic beam, leading to a gentler effect which can still transmit extraordinarily powerful gravitational fields. This is how gravity tethers and artificial gravity generators can be used by living beings and not injuring them with intense heat (though the kinetic energy and sudden acceleration of the artificial gravitational
field may still present danger). Grasers also have a use in creating other offensive and defensive technologies, most notably that of mass accelerators and energy shielding, respectively. Mass accelerators use a very small speck of metal accelerated to incredibly high speeds by gravitomagnetic fields. In addition, the speck's mass is also reduced by quintessence fields located in the barrel, allowing the projectile to possess a much higher velocity than was previously possible as well as a much higher kinetic energy (this does not violate energy conservation because the extra kinetic energy of the projectile has been extracted from the vacuum via the quintessence fields). Energy shields, meanwhile, are defensive fields of gravitophotons which are projected from small emitters on body armour or the hull of a starship. Energy shields prevent solid objects and gravitophoton-based beams from damaging a structure, and are essential in modern combat.
