Apocalyptic doomsday scenarios predicted by physics
27 mins
A rather unusual blog post for this site, a collection of various doomsday scenarios predicted or at least allowed by physics that might happen for sure (but don't be frightened, usually with a really low probability). Note that this is not an in depth article but just a short overview of some scenarios.
