You may be interested in The Hitchhiker's Guide to the Galaxy, where, due to a terrible miscalculation of scale, an entire battle fleet was accidentally swallowed by a small dog. The planet on which the dog was located then exploded, but not due to the battle fleet, instead it was because some people didn't want the planet to provide the right question to an answer they already had, but they didn't realise they didn't need to owing to the accidental interference of a dead species that had sent away all their telephone sanitisers before being wiped out in a pandemic caused by a dirty telephone.
