So, if my understanding of GRBs is correct, they are a collimated jet of material that produces a lot of gamma rays. So my question is, don't these have to be pointing right at us for us to see them? If so, then why do we see so many? I think it's at around at least one per day, the last time I checked. Does this mean that there are *a lot* more that we aren't seeing? Or do I have a misunderstanding of how we are able to see them?
