- 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 :-).
