I wasnt asking about the gate address in stargate i know how it works (you can gate from an other galxy with enough power and an 8th chevron) i wanted to know if the 6point address for earth in the show does point to earth in real llife

I was watching first episode of farscape today and i wanted to know: "If i was lost on the other side of the universe how could i show earths location" than stargate came on and i thought that the gate address (with out the point of origin)[Earths address is "Auriga, Cetus, Centaurus, Cancer, Scutum, Eridanus"] would work. So does the stargate address used in the show Point to earths location if not can earth be identified by the same way? Also if that fails how do i identify were earth is on a starmap??
