A stargate's destination is not fixed, but is singled out by a process known as "dialing". Once a three-dimensional destination is selected by the traveler, the Stargate generates a stable wormhole between itself and a complementary device at the destination, by being supplied with a threshold amount of raw energy. Objects in transit between gates are broken down into their individual elemental components, and then into energy as they pass through the event horizon, and then travel through a wormhole before being reconstructed on the other side.
