Wormhole

An energy conduit formed between two active Stargates. A Stargate transfers a person or object into energy as it passes through the Event Horizon, then transmits it through the wormhole to the receiving Stargate -- which then reconstructs the matter in its original form. Wormholes traverse vast distances across the galaxy, and even between galaxies. The conduit does not always exist, but is formed only between two active Stargates. An object can travel in only one direction in a wormhole, through the initiating gate.
