How many wormhole

Te adresses of the Milky Way

38 symbols on a DHD, (-1 because the start point is constant): 37 variable 37*36*35*34*33*32=1673844480

In the article: “With 38 symbols, the Stargate Network in the Milky Way has 1,987,690,320 possible 7-symbol addresses.”

Why??? --Stewe007 (talk) 05:14, 18 January 2010 (UTC)

Practically (because the address is 6 point only) the sequence is indifferent:same gate or not make wormhole

${\frac {1673844480}{6!}}=2324784$ possible 7-symbol addresses.

No, the sequence does matter according to the explanation in the movie - and I don't remember anything that said otherwise in the series. Each pair of symbols defines a line running between the identified constellations. So if your address is abcdefg, you have lines ab, cd, and ef, and the intersection point is the destination. But lines ac, bf, and de would be a different set of lines, hence a different destination - if any; those lines would probably not intersect. It makes no sense either way (you only need two intersecting lines to determine a point in space, and constellations do not have a single defined location in 3d space anyway) but that's what they said.

$37*36*35*34*33*32=1673844480$ is the correct answer since Stargate addresses are permutations without repetition, not combinations. Excluding the origin, you only have 37 symbols to pick from. You can and must use 6 symbols at one time(disregarding the 7th, 8th, and 9th chevrons). You can't use the same one more than once. And the order matters. --The godfaza 12:36, 6 March 2010 (UTC) —Preceding unsigned comment added by The godfaza (talk • contribs)

In my opinion the order matters, but not as you think. Consider six points in a three-dimensional space. There is only one set of three lines linking two points each that can intersect in a single point or approximately doing so. This means that every planet must have its unique combination of 6 symbols, but to succesfully dial you must also input the right permutation so the system can locate it. 85.49.153.238 (talk) 09:48, 10 June 2010 (UTC)

Geometry says that the line AB and the line BA are one and the same. So the address AB.CD.EF should be the same as BA.CD.EF. Likewise, if we're just constructing three lines in space, the order in which we choose the lines shouldn't really matter, so the address AB.CD.EF should be the same as AB.EF.CD. Thus we have C(38,2)*C(36,2)*C(34,2)/6 = 41410215 distinct addresses. To explain the formula:

C(38,2) -> Picks the first two symbols without regard to order (AB=BA)

C(36,2) -> After picking the first two, there are 36 symbols left and we need to choose two.

C(34,2) -> Same rationale as previous.

Then we need to divide by 6 to 'unorder' the lines, since AB.CD.EF = AB.EF.CD. We have 3 lines, so there are 3! = 6 ways to arrange the three lines.

Though in the first episode of Atlantis, McKay mentions inputting the symbols 'backwards and forwards', so there might be something unexplained about the manner in which addresses work, but going strictly by the geometry explanation there are 41410215 distinct addresses available in the Milky Way.

sgu chevron symbols

You can't have two origin symbols. Which one is right? 67.169.34.161 (talk) 20:47, 14 May 2010 (UTC)

Use of the term "stargate" in other works

This section broadens the scope of this article too much. We already have Stargate (disambiguation), so I am going to remove it.--~TPW 16:24, 13 June 2010 (UTC)

Stargate inner ring rotation

I know this doesn't seem important to the article but I thought someone here might know:

What are the rules governing which direction each gate spins to select each symbol? In standard milky way gates the ring does not spin at all, but does the Stargate command, Pegasus, and universe gates rotate in such a way to select the symbols the quickest or are they intended to always switch direction after selecting and if so which way do they start off. --72.64.105.184 (talk) 22:41, 30 July 2010 (UTC) All three models follow the same pattern: first they spin clockwise, engage the first chevron, spin counter-clockwise, engage the second chevron, spin clockwise and so on. —Preceding unsigned comment added by 80.103.194.110 (talk) 23:24, 7 November 2010 (UTC)

Atlantis constellation names

Joe Malozzi on his block released the SFX documents that gave the names of all the Atlantis gate constellation names for SFX work and props. Why aren't these attached to the atlantis glyph list?121.44.175.119 (talk) 07:48, 31 August 2013 (UTC)

Questionable Travel Time References In Article Head

In the opening paragraph of the article, it states:

"As space and time are relative, a person traveling through the Stargate may feel as though he or she is traveling for long periods of time while persons outside the Stargate would see instant travel. In one of the earlier episodes, Col. Jack O'Neill made a comment about it feeling like it took forever to travel through the wormhole."

I do not recall any of this being stated in the series. Additionally, that is the opposite of how relativistic time observation works (I.E. the person traveling should feel no or little time pass, while the observer would see more time pass), so the explanation for the conclusion is, at best, dubious. In which episode did Jack make that comment? We do have early comments about the trip taking something like 3-5 seconds, but later the trip is said to take fractions of a second. (No, I do not have episode references, which is why I won't put that in the article.) I don't recall any case of someone claiming it feels like a long time except possibly in a sarcastic or rhetorical context, and I'm not even certain of that.

Please either clarify or remove this unfounded statement (or 'found' it with some citation). If I'm wrong I'll happily admit it, but I would like to see some reference. Tacticus (talk) 01:58, 13 December 2013 (UTC)

The series often suggested the opposite, where the travel time was instantaneous relative to the traveler. At one point, a character was “stuck” in the Stargate for an extended period of time, and when retrieved had no awareness of what happened. Any quip by Jack O’Neill about it taking forever was likely sarcastic, as were many of his comments. Alec (talk) 20:49, 14 June 2014 (UTC)
