Abstract. "There is a theory which states that if ever anyone
discovers exactly
what the Universe is for and why it is here, it will instantly disappear
and be replaced by something even more bizarre and inexplicable.
There is another theory which states that this has already happened."
Douglas Adams, The Restaurant at the End of the Universe
