Extent of knowledge of potential future gamma ray bursts What do we know about the locations and directions of potential Gamma ray bursts that may intersect with Earth in the future, or are we mostly blind to when such an event directed our way may occur &amp; cause a mass extinction event?
In other words, are we able to predict to any degree at all when one might occur close enough that there may be some potential impact to life or life on Earth or infrastructure?
Although not being an expert on the field, I found a multitude of studies dealing with events which may be used as indicator that a GBR is about to happen somewhere. Research on GBR precusor events range from smaller gamma ray precursors, over gravitiational waves, to thermal signatures, and neutrinos:
