Quantum relativity: An essay.

We investigate the possibility to obtain gravity as a deformation of electromagnetism (EM), in the context of Quantum Information Dynamics (QID) and Deformation Theory. Planck's constant is "dual" to the speed of light c, viewed as a deformation parameter, and the effect of "quantum gravity" could emerge from such a modification of the external symmetry group, away from a geometric construction (manifold). A toy model of gravity is proposed as a complex deformation of EM. Gravitational mass comes as a small imaginary perturbation of the EM effective charge, breaking the negative-positive symmetry, conform to the electron and proton models within the standard model. References to current experimental and theoretical investigations in this direction are included. [ABSTRACT FROM AUTHOR]
