Stargate

"That is how we're supposed to travel light years across the galaxy to other planets."

- Cameron Mitchell

Stargates, also called Astria Porta in Ancient and Chappa'ai in Goa'uld, as well as various other names across the universe, are a series of devices built by the Ancients which create wormholes, allowing for near-instantaneous transportation between two distant points in space. The Stargates are often considered to be the Ancients' greatest creation and thus, the Ancients are often referred to as the Gate Builders. The Ancients, the Asurans, the Tollan with the help of the Nox, and the Ori are the only known races capable of constructing Stargates.

The original Stargate design was created by an Alteran named Amelius, from an idea he formulated the night before the Alterans left their home galaxy for the Milky Way. However, it is unknown if he actually established the first of the Stargate Network They are among the oldest examples of Ancient technology found in the Milky Way galaxy; the Stargate found in Antarctica on Earth has been estimated to be over 50 million years old, while the Stargates used in the "Destiny mission" are even older.
