    8th chevron

    Ok i know that the 8th chevron adds an extra distance calculation but why, 6 points and point of origin should be enough, does any one know why it needs 8 as in points in a three dimetional space?

    It adds the galaxy distance calculation. In order for the system to work the 6 points have to be measured by predetermined points in space around the outside of the galaxy so the intersecting lines can be plotted. the default is that it automatically uses the home system of coordinates for the galaxy you are in, the additional chevron (which is actually the seventh when you are dialing because PoO still has to be last) tells it to calculate using the coordinates for the other galaxy.

      let's sift ths to a 2D plane for simplity.

      We ave 2 sheets of grid paper. Each one is divided into the normal 4 sections. Now (3,2) could be that point in eith sheet, so we add another thing to explain which one

          Have they ever explained why three intersecting lines are needed, and not two?

          That has sort of never made sense to me.

            because space a 3 dimensional reality, not 2. With only 2 line you can calculate the distance on only one plane.

              but the gate doesnt travel to other planes well unless the 9th cheveron theory is correct??

                plane as in mathematic calculations, not planes of reality. you can only calculate along an x and y axis with only two lines, you need a third line for z

                  First of all, its TV and second, I don't think they really thought it out, they've basically made it into an area code...

                    Sorry, but that doesn't really make sense. If you have two intersecting lines, why do you need a third one?

                    EDIT: It would have made more sense to make the address of a planet represent a vector so it doesn't depend on constellations, but its a TV show, so I suppose its not going to make sense.

                      ok take a piece of paper and draw two intersecting lines on it. The lines come together at a single point. Now hold that paper up in front of your eyes. the piece of paper represents one single plane in space, a measurement based on front to back measurment and side to side. However in space things also have to be measure up and down, thats the z axis. With out that additional measurement the point in space that the planet is at could be anywhere along that vertical axis. Its hard to explain over a message board.

                      And the constelations thing was just in the movie and worked when it only went to one place. Its never been carried over or utilized in the show.

                        If two lines intersect in 3 dimensional space, that is still going to give you a single point, not an entire line. You can find the intersection of two lines in three dimensional space pretty easily. (if they have one, not likely however)

                        Two lines intersecting is just as good as three lines intersecting.


                        here, I have attached a picture of two intersecting line segments. Explain why thats not as good at three intersecting line segments.

                          no it does give you an entire line. if you have a 2 foot by 2 foot by 2 foot cube and make two lines cross in the middle a foot from each wall you still havent specified how far from the top or bottom of the box the point is so it could be any point along the line that exists 1 foot from each side

                            I am going with this one. It adds for distance.

                              look at the attachment I added in my previous post, and tell me why those two intersecting lines dont give you a point.
