and it eliminates the rather unlikely supposition that every other race in the galaxy has gone to the trouble of learning English. Fictional depictions Doctor Who Using a telepathic field, the TARDIS automatically translates most comprehensible languages (written and spoken) into a language understood by its pilot and each of the crew members. The field also translates what they say into a language appropriate for that time and location (e.g., speaking the appropriate dialect of Latin when in ancient Rome). This system has frequently been featured as a main part of the show. The TARDIS, and by extension a number of its major systems, including the translator, are telepathically linked to its pilot, the Doctor. None of these systems appear able to function reliably when the Doctor is incapacitated. In "The Fires of Pompeii", when companion Donna Noble attempts to speak the local language directly, her words are humorously rendered into what sounds to a local like Welsh. One flaw of this translation process is that if the language that a word is being translated into does not have a concept for it, e.g, the Romans don't have a word or a general understanding of "volcano" as Mt. Vesuvius has not erupted yet. Farscape On the TV show Farscape, John Crichton is injected with bacteria called translator microbes which function as a sort of universal translator. The microbes colonize the host's brainstem and translate anything spoken to the host, passing along the translated information to the host's brain. This does not enable the injected person to speak other languages; they continue to speak their own language and are only understood by others as long as the listeners possess the microbes. The microbes sometimes fail to properly translate slang, translating it literally. Also, the translator microbes cannot translate the natural language of the alien Pilots or Diagnosans because every word in their language can contain thousands of meanings, far too many for the microbes to translate; thus Pilots must learn to speak in "simple sentences", while Diagnosans require interpreters. The implanted can learn to speak new languages if they want or to make communicating with non-injected individuals possible. The crew of Moya learned English from Crichton, thereby being able to communicate with the non-implanted populace when the crew visited Earth. Some species, such as the Kalish, cannot use translator microbes because their body rejects them, so they must learn a new
