Nanomachines: Difference between revisions

** Nanites appear in several episodes of ''[[Stargate SG-1]]'', although the earlier ones appear to be an evolution of a less-sophisticated group of Replicators which seem to have been independently created. <ref>One of the more widely-accepted theories within Stargate fandom is that after the Ancients left the Pegasus Galaxy to return to the Milky Way (leaving the Asuran Replicators behind), one of them decided to go off on his own and restart the project, but with more control exerted over it to ensure that they didn't get out of control like the Asurans did. Unfortunately, things [[It Got Worse|didn't quite go to plan]].</ref>

** Fanon and the Expanded Universe hold that the unsophisticated ''[[Stargate SG-1]]'' Replicators encountered the advanced ''[[Stargate Atlantis]]'' Replicators at some point in the past or during the series and cribbed the ability to create human-form Replicators from them. However, canon explicitly states that the Milky Way replicators got the idea for human form from Reese:

'''Third''': We are composed of millions of cell units, microscopic in comparison, that combine to create this form. }}

** ''[[Stargate Atlantis]]'' features a nanovirus that kills several members of the Atlantis Expedition and nearly kills many more [[Stargate Atlantis/Recap/S01 E13 Hot Zone|during its first season]] (possibly Asuran nanobots). Also an example of criminal neglect from the [[Precursors]] (Ancients). (To be fair, though, they thought they would be coming back, and couldn't really have foreseen the humans, who were still hunter-gatherers when they left, taking over. They weren't really jerks until they Ascended.) Nanotechnology is used fairly regularly in the later seasons, the most notable example being the human-form Replicators, originally designed by the Ancients.
