He smiled as he reached into a small pouch on the side of his belt pulling out another disk putting the wire in the computer. "As far as we can tell The symbols used to compose addresses are actually pictorial representations of star constellations. By identifying six constellations in space, a single point can be interpolated that corresponds to the destination desired. As only a small portion of the possible combinations of Stargate symbols represent valid addresses, dialing the Gate at random is largely futile. I started off giving them the address of world found by the kree but not claimed by empire."
He kept typing and a flow of data came through. "The Gates are made of a substance called Naqahdah, A rare, superheavy metal first depicted as a quartzite like mineral, naqahdah greatly amplifies energy, making it extremely potent if paired with explosives of any kind.
Due to its unique properties, naqahdah forms the basis for many advanced technologies. Most Kree warship weapons use the materiel. the Stargates themselves are composed almost entirely of naqahdah." The Kree empire uses them before we had starships. There is a Theory that humans and the Kree have a common ancestor of sorts. I hope I'm not boring you doctor."
