Like an unendingly long shotgun blast that's flung out in every direction. Only instead of being 20-gauge or 12-gauge, it's neutron star-gauge. You don't want to be down range from it, and every direction is down range. You're in the "crosshairs" even if you're firing the gun. Good article, thanks. Ruined my day. ;-)
In this case, though, "local" is billions or trillions of miles.
