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.

regards,
Jürgen
