The Hitchhiker's Guide to the Galaxy has this to say about Barcelona (planet Barcelona, not city Barcelona and most certainly not black hole of the same name): once upon a time it was funny little planet famous mostly for its dogs with no noses. But since then universe changed…. time bent… things happened. No one seemed to be able to find it nowadays. Not that it disappeared like Poosh or Paravelia, no most of the scientists, politician and even occasional philosophers all seem to agree that it's where it should be. Occasional travelers even claimed to visit it, so after two pangalactical blaster you will not only see Barcelona, but in addition to it Gallifrey and Daleks singing and dancing in a ring. The Guide advises you to keep clear of any ships heading for Barcelona. That's for your own good. And even if that line never works, the Guide declines the responsibility for any of your further actions, dear hitchhiker.
