Hmm.  Weird that it only occurs for short bursts, then.

I listen to "Earth and Sky," a public radio show that airs in the middle
of "Morning Edition" here in Riverside.  Yesterday they said that
someone is trying to use gamma ray bursters to investigate dark matter.
I guess the idea is that if dark matter is fairly big hunks of stuff
(comet-sized??) it should cause some distinctive dispersion in the gamma
rays.  Does anyone know anything about this idea?  It's not clear to me
how much info one can get without understanding the bursters at all.
