Default Are we observing Lorentz violation in gamma ray bursts?

This is an exciting time in physics as our instruments and experiments
allow us to probe the mysteries and unanswered questions with a
precision we could not have even been close to in the past. With that
said the level of discussion in this newsgroup has become stale and
boring. I suggest those that can understand should go and read the
latest preprints on Arxiv and get ideas and new questions on subjects
for this newsgroup. Today I found this interesting preprint which could
point the way to new physics. It is just a preprint so keep that in
mind and let your physical senses be the guide to what is real!


From recent observations of gamma-ray bursts (GRBs), it appears that

spectral time lags between higher-energy gamma rays photons and
lower-energy photons vary with energy difference and time (distance)
traveled. These lags appear to be smaller for the most luminous (close)
bursts but larger for the fainter (farther away) bursts. From this
observation, it has been suggested that it might be possible to
determine the distance (L) these bursts have traveled from these time
lags alone, without performing any red-shift measurements. These
observed spreads (dispersion) of high energy electromagnetic pulses of
different energies with time contradict the special theory of
relativity (STR). However, extended theories (ET) of the STR have been
developed that contain a dispersive term, predicting the above
observations. An example of such an ET is presented, allowing us to
derive a relationship between time lags of gamma rays of different
energies and distance L traveled from their origin. In addition, this
theory predicts the origin of X-ray flashes.
