[[WMG:''Stargate Infinity'' occurs in an Main/AlternateUniverse in relation to the ''[[Series/StargateSG1 SG-1]]/[[Series/StargateAtlantis Atlantis]]/[[Series/StargateUniverse Universe]]'' universe.]]
Like [[Film/{{Stargate}} the original movie]]. In "There But for the Grace of God", the alternate Carter says that alternate universes differ in their degrees of likeness to each other. It's not inconceivable that there's an alternate universe in which the Stargates have eight chevrons rather than nine, and the Ancients are Dragon-people.

[[WMG:''Stargate Infinity'' was created by Martin Lloyd.]]
It was produced as a LighterAndSofter spinoff of ''Wormhole X-Treme'', and it was ''deliberately'' inaccurate to help maintain TheMasquerade.

[[WMG: The 8-chevron Gates in Infinity are actually another variant of Stargate rather than a {{Retool}}]]
Perhaps constructed by a race which reverse-engineered the Stargate and resolved some of its hazards, such as the disintegration of objects in the path of the unstable vortex. Such a race might not have had a need for 9-chevron addresses or not have been aware of them.
