This will not be a very informative article :-)
The small things I've heard, is that one tries to see whether the gamma-ray
bursts are uniformly distributed over the sky, and recent results seem to
indicate that.
If this is right, that will clearly indicate that these bursts are extra-
galactic in origin (I will _not_ say prove, because one could think of
the possibility that the bursts could come from the spherical halo of our
galaxy). If this is so, I guess we could be in for a treat, since we then
have to come up with the sources.... Lot's of fun for theorists :-).
