This would be really scary if it was relatively eminent, but its like so far away that we would have 5th dimensional technology if we survived as a species by then and could slip into different parallel dimensions where issues don't happen or way more likely before would have already populated many exoplanets rendering this not even an issue. Did I mention I don't know what the hell I'm talking about?
