The sun is simple. A sword is simple. A storm is simple. Behind everything simple is a huge tail of complicated.
Terry PratchettNo more words. We know them all, all the words that should not be said. But you have made my world more perfect.
Terry Pratchettat least nine-tenths of all the original reality ever created lies outside the multiverse, and since the multiverse by definition includes absolutely everything that is anything, this puts a bit of a strain on things. Outside the boundaries of the universe lie the raw realities, the could-have-beens, the might-bes, the never-weres, the wild ideas, all being created and uncreated chaotically like elements in fermenting supernovas. Just occasionally where the walls of the worlds have worn a bit thin, they can leak in.
