How many chevrons are on the Stargate?
Nine, spaced at 40-degree intervals, though only the top seven are usually visible (theramp in the S.G.C.’s gate room and the pedastals on most planets hides the lower two). In “Stargate” the movie, you can see the tip of one of the lower chevrons just to the left of the smaller ramp in the Abydos Stargate chamber, as Daniel puts on his cap soon after arriving. Though some have claimed that there are only seven chevrons on the gate, the bottom two are clearly visible in some episodes (most notably “Nemesis,” when the gate is transported to Thor’s ship, and “Redemption, Part 2,” as the gate is raised out of the S.G.C.).
