Since the stars in a galactic core are very close together, if one star explodes, could the resulting energy influx trigger similar explosions in surrounding stars, causing a chain-reaction? Have we ever observed a galaxy in that condition? Should something like this happen to our beloved Milky Way, what would the eventual consequences to Earth be? It seems to me that there would be a massive radiation front expanding outward from the explosions, and some 30,000 years later it would reach us. Would any existing humans still survive after that? What about the galaxy itself after an event of this magnitude?
