Poland

In the BZPB Multiverse, Poland is always the last remaining piece of Earth after its destruction. It floated around in a giant bubble of air in space, until another Earth popped up to take the place of the first one. When Earth was destroyed again, guess which country survived and was blasted out into space? Yep, Poland. We're not sure whether this means that there are now two Polands floating around in space somewhere, but the prospect is terrifying.
