processes into the plot). In the season 8 finale of SG-1, “Moebius (Part II),” the characters go back in time to 3000 B.C. and one of them teaches English to the people there. A notable exception to this rule are the Goa’uld, who occasionally speak their own language amongst themselves or when giving orders to their Jaffa. This is never subtitled, but occasionally a translation is given by a third character (usually Teal'c or Daniel Jackson), ostensibly for the benefit of the human characters nearby who do not speak Goa’uld. The Asgard are also shown having their own language (apparently related to the Norse languages), although it is English played backwards. (See Hermiod). In contrast a major plot element of the original Stargate film was that Daniel Jackson had to learn the language of the people of Abydos in the common way, which turned out to be derived from ancient Egyptian. The language had been extinct on Earth for many millennia, but Jackson eventually realized that it was merely errors in pronunciation that prevented effective communication. Star Trek In Star Trek, the universal translator was used by Ensign Hoshi Sato, the communications officer on the Enterprise in Star Trek: Enterprise, to invent the linguacode matrix. It was supposedly first used in the late 22nd century on Earth for the instant translation of well-known Earth languages. Gradually, with the removal of language barriers, Earth's disparate cultures came to terms of universal peace. Translations of previously unknown languages, such as those of aliens, required more difficulties to be overcome. Like most other common forms of Star Trek technology (warp drive, transporters, etc.), the universal translator was probably developed independently on several worlds as an inevitable requirement of space travel; certainly the Vulcans had no difficulty communicating with humans upon making "first contact" (although the Vulcans could have learned Standard English from monitoring Earth radio transmissions). The Vulcan ship that landed during First Contact was a survey vessel. The Vulcans had been surveying the humans for over a hundred years, when first contact actually occurred to T'Pol's great-grandmother, T'mir, in the episode "Carbon Creek"; however, in Star Trek First Contact it is implied that they learned English by surveying the planets in the Solar System. Deanna Troi mentions the Vulcans have no interest in Earth as it is "too primitive", but the Prime Directive states not to interfere with pre-Warp species. The Vulcans
