We're looking straight down the barrel of a Really Big Gun. I've read about how these puppies go supernova and yep, it's a really big gun with a hair trigger if it's a Wolfe-Rayet. Fully-loaded and unfortunately, pointed toward us. That, however is not enough to incentive to start building that underground survival shelter and finally procure that heard of sheep you've been meaning to steal from your neighbor. We still have to firm up how precise the orientation is and how large the gamma ray burst will be. Supernovae differ, just like people and bong hits.
Peace until the apocalypse
