Hello Richard,

Now as I see it, a group velocity was measured at greater than c, and
thus, in contrast to the Fizeau near fit, the relativistic velocity
addition equation fails in this current experiment. Not only that, but
the whole of special relativity has been proved false.

No, it hasn´t. SR forbids *transport of energy-momentum at
superluminal speeds*, and in the case of anomalous dispersion, as in
this experiment, energy-momentum is not transported with the group
velocity of the wave package. So superluminal group velocities don´t
violate SR.

Where in the lorentz transform is it implicit that v corresponds only to
tangible particles? You are only repeating what you've heard over and
over. This was an outright lie imposed in order to save SR from very
observable superluminal speeds. It was a rationalization, it was a
fabrication, it was pulled out of their asses. Tell me, If a spot
(generated by a rotating laser) is moving at 2c along a fence wrt me,
then what speed will that spot be moving wrt an observer moving at x m/s
wrt the fence, as measured by that observer?
