Just wondering if there's any discussion about new gamma-ray observations and what they may say about high-energy physics. I've heard bits and pieces about how gamma-ray bursters can be used to probe the nature of quantum gravity in terms of a vacuum refractive index. This has to do with delay times in gamma-ray burst photons according to wavelength.

Secondly, I've heard rumors about some type of gamma-ray burst measurements that could contradict the dark-energy hypothesis (perhaps a distance-luminosity relation measurement).

Perhaps the new Fermi space observatory will help with some fresh observations.

P.S. And here's another unmanned yet non-planetary thread After posting this I see the mainly prelaunch GLAST thread from a few months back.
