It is known that there are an infinte number of worlds simply because there is an infinite amount of space for them to be in. However not every one of them is inhabited. Any finite number divided by infinity is as near nothing as makes no odds so the average population of all the planets in the Universe can be said to be zero. From this it follows that the population of the whole Universe is also zero and that any people you may meet from time to time are merely products of a deranged imagination.
Douglas Noel Adams (11 March 1952 – 11 May 2001) was an English author, scriptwriter, essayist, humorist, satirist and dramatist. Adams is best known as the author of The Hitchhiker's Guide to the Galaxy, which originated in 1978 as a BBC radio comedy before developing into a "trilogy" of five books that sold more than 15 million copies in his lifetime and generated a television series, several stage plays, comics, a computer game, and in 2005 a feature film.
