    "abstract": "The experiment proposed aims to evidence and to measure the deflection of\nlight rays induced by the source speed upon emission, and to discern it from\nthe aberration of light rays induced by the observer speed. The method stands\nin creating a speed asymmetry between that of the source and that of the\nobserver, and relies on the centrifugation of a light source at ultrahigh\nspeed. When source and observer have the same speed, such as when being both on\nthe same inertial system, the deflection and the aberration compensate and\ntheir net effect is null. So, in order to circumscribe the odds of inertial\nsystems and to isolate these speed-induced effects it has instead been appealed\nto a centrifugal system, since it allows infringing symmetry between the source\nand the observer speeds. Three cases are considered. (a) Centrifugation of the\nsource fixed at one end of the rotor arm, while the detector is fixed on the\nrotor axis. This configuration of the experiment aims to unveil that due to the\nperipheral speed of the source the beam is deflected forward, so it impinges on\nthe centric detector slightly shifted from its position when the system was not\nrotating. (b) The positions of the source and the detector are interchanged, so\nthe source peripheral speed is then null and thus no speed-induced deflection\nensues, but due to the observer peripheral speed there is a speed-induced\naberration since during the beam time-of-flight the detector has slightly moved\nside-way. However, this time the spot shifts in opposite direction and hence\nthe effect of centrifugation is not reciprocal. (c) The source and the detector\nare fixed at the two ends of the rotor arms. In this case the beam deflection\nand aberration add, since their speed vectors have opposite directions and each\nshift of the spot on the detector is double since the time-of-flight is double.",
