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