Who knows? What I do know is that upon reflection, SR is incompatible
with any superluminal speed, even of a non-thing.


Wrong. As always. The speed limit of c in SR applies to matter,
energy, and information. The limit does not apply to interference
patterns, shadows, projections, and cuts.

I think the trick here is the barrier they use it to alter the wave form
so the peak of the wave is advanced. Then the detector detects it sooner
than if it was not manipulated. i.e. chart an x any y graph and run a
sine wave through so a new wave starts at zero, continue the wave in the
negative direction also. Now make a sine wave with a longer wavelength,
but only on the right side. A detector would detect the longer wave first.

c only applies to matter with relative mass..
No relative mass... No speeding tickets....

"Science is not gadgetry. The desirable adjuncts of modern
living, although in many instances made possible by
science, certainly do not constitute science. Basic scientific
knowledge often (but not always) is a prerequisite to such
developments, but technology primarily deserves the credit
for having the financial courage, the ingenuity, and the
driving energy to see to it that so-called “pure knowledge”
is in fact brought to the practical service of man. And it
should also be recognized that those who have the urge to
apply knowledge usefully have themselves often made
significant contribution to pure knowledge and have even
more often served as a stimulation to the activities of a pure
researcher."

There are plenty of scientific papers and news reports touting
superluminal velocities and even negative transit times for pulses of
light propagating through atomic caesium vapor.

I wonder if this is all nonsensical hoopla based on the antiquated
wave theory of light or if there is a real, measurable
faster-than-light particle view of quantum mechanical tunneling going
on. If I understand Richard P. Feynman correctly, photons are always
particles; the wave nature of light only reveals itself in terms of
probabilities. All quantum mechanists know the rules of adding
amplitudes but I would like to know if something new about quantum
mechanical tunneling has been revealed. Are individual photons in
these experiments moving at velocities faster than light?

Answer:

The sheer mention of this result together with Einstein's theory of
special relativity and the principle of causality is a scam. Not a
single photon is moving faster than light.

The alleged generation of superluminal velocities without violating
causality is intentionally misleading physicists' hoopla and all the
media hype is pure distortion. The fact that the dramatic 60 ns
advance is only one fiftieth of the width of the pulse is a clear
indication of this.

If you were hoping to conceptualize how Einstein's special theory of
relativity might be false, then don't let these facts disappoint you.
It is possible to modify Einstein's special theory to allow for motion
faster than light.

Suppose a particle is moving along in tandem with the group wave. SR
velocity addition applies to the particle, and the speed of the particle
wrt lab frame is

(v+w)/(1+vw/c^2)

and since for any velocity of the particle wrt the frame of any given
phase wave, the speed of the particle must always be less than c, then
according to the equation it will always be less than c wrt lab frame
also.

What we have in the cesium experiment though, is an apparent inability
to correlate the group wave to that of a particle moving in parallel to
it at the same velocity. If the group velocity exceeds c, then no
particle can move along in tandem with it. The interesting thing is,
that at c, the particle will traverse infinite lab frame distance in
zero time wrt its own frame, thus the group speed which is greater, per
above, requires that this group wave move backward in time wrt lab
frame.

However the group wave will not actually appear at the outlet before the
beam strikes the surface of the cesium cell, for obvious reasons, one of
which is that a shutter can be located at the entry point of the cell
that can shut off access of the photons to the cell after the group node
has already exited. Thus the beam will have never entered the cell to
create the group node that exited nonetheless. This is pure idiocy.

SR doesn't allow for group velocities greater than c, though it does
allow for transverse phase wave velocities greater than c. In the cesium
experiment you should note however that the group velocity is not
transverse, it is longitudinal.

SR has been proved by the experiment to be untenable.

And yet Nature's speed limit is not locally violated for mass in
motion, propagation of electromagnetic radiation or communication
of information.

The Java applet is false
it shows several component waves traveling with different speed,
the top is the slowest and the bottom the fastest.
Also it is irrelevant to the subject of single pulse transient.

Bologna mathematicians are not able to show such applets for the single
gaussian pulse transient!

Mathematical bologna!

Why do people think if you go faster than light you can immediately go
back in time?
i.e. if you could travel at twice the speed of light it would still take
two years to get to alpha centuri, right?

Yup...

The problem is definitions of SR as to 'event sequencing'. LRT does
not have this problem since it does NOT have a defined
synchronization process that sets time as a pseudo-distance...
