Unlike /dev/null, /dev/full is a place of complete knowledge. It is believed that Ancient Unix gurus placed it in there to attract fools and to make them think that power and wisdom were waiting for them at the end. But /dev/full contains so much information that no one can survive the trip there. Some scientists have presented theories about /dev/full that resemble worm holes. This way, someone entering in /dev/null would come out of /dev/full.
