The team studied two gamma-ray flares in mid-2005 from the black hole at the heart of the galaxy Markarian 501. They compared gammas in two energy ranges, from 1.2 to 10 tera-electron-volts (TeV) and from 0.25 to 0.6 TeV. The first group arrived on Earth four minutes later than the second. One team member, physicist John Ellis of CERN, says: "The significance of the time lag is above 95%, and the magnitude of the effect is beyond the sensitivity of previous experiments." Either the high-energy gammas were released later (because of how they were generated) or they propagated more slowly.

Probing quantum gravity with gamma ray burstersTheir results -- a time difference of 3-4 seconds after traversing huge distances -- rely heavily on the reconstruction of the source's emission profile so they also checked that using computer models. Essentially, they made up a bunch of sources that gave photons arbitrary emission times and tested their ability to calculate the vacuum dispersion on those. More specifically, they used computer generated profiles that were then dispersed by a vacuum that was either dispersive or non-dispersive. In all cases they recovered the original source profile to within the uncertainty of they experimental observations. This tells us that the source profile is probably the leading cause of uncertainty in these observations.

Has quantum gravity made a sudden leap forward? Probably not, but this is the first real data against which such a theory can be tested, which means that theorists will suddenly have to start paying attention to experimental results again and modify their theories appropriately.

Cool.
It’s possible that a correction factor might be needed for the law of conservation, kinda like the relativity theory is a correction factor for Newtonian Physics at the atomic level.
Here’s one to check out:

The gammas were measured in two energy ranges, from 1.2 to 10 tera-electron-volts (TeV) and from 0.25 to 0.6 TeV. The first group arrived on Earth four minutes later than the second.
We do not know the origin of these gamma bursts, it might have been some type of acceleration process that produces different energies as times goes by.
Here is the original article http://arxiv.org/abs/0708.2889
It’s all kind of like a kid clamoring for attention. You have to make a big disturbance to get noticed.
Our measuring techniques are not quite up with our imaginations yet (nor will they ever be)
