Gammaray burst (GRB) observation is opening up prospects for testing physical theory.
In particular there are quantum models of gravitational collapse and of black holes which may be testable by observing NS-BH mergers (jargot for "neutronstar-blackhole")
Do you think some of today's QG approaches are testable? Could any be refuted by GRB observations, in your opinion? And if you think so, then HOW can GRB provide tests for QG?

Steinn Sigurdsson watches the GRB reports here:

and he comments on GRB here

...Combined with GRB051211 we're now seeing what seem to be moderate redshift short lived progenitors; it is tempting to say we are seeing two sub-classes of short GRBs, one set associated with NS-NS mergers and longish(?) lifetimes before merger, the other being shorter lived NS-BH mergers...
