Cool stuff. There was a discussion just the other day about gamma ray bursts where I am currently studying....and this morning actually There is a lot that is still not understood about them but I personally think some of the more recent observations coming in are shedding a lot of light on the whole thing and will help to narrow down exactly what is going on with them. Given what was said, I personally think somebody will be able to do a simple quantitative analysis relatively soon that should help tie it all together....well somewhat "simple" anyways.
