Tests of Lorentz Invariance Violation with Gamma Rays to probe Quantum Gravity

Special and general relativity extended our understanding of the concepts of space and time,two of the most basic topics of investigation of modern physics. However, quantum theory hasshown that there is more to learn regarding these concepts. The group of Lorentz transformationsis scale invariant. However, considerations of how to combine the concepts of quantum mechanicsand gravity (quantum gravity) indicate that there is a “natural scale” at which the physics ofspace-time predicted by relativity theory breaks down and thus requires modification, or a newparadigm (Saslow, 1998). This natural scale is the Planck scale, E
