I was reading this article about
Wolf-Rayet , a binary star system which could potentially send a "Gamma Ray Burst" our way some day.
It occurred to me that this star could have gone nova at any point in the last 8,000 years. The rays which could be our doom could be at this second speeding towards us at 186,000 miles a second, and we wouldn't know it till they got here.
To think we may have already been killed by a gun fired at the dawn of human civilization, only we don't know it yet.
Dead planet walking.
