Stargate Universe is set on the Ancient ship Destiny, which was launched unmanned hundreds of thousands of years ago. Several ships were sent ahead of it to seed the universe with Stargates. The Ancients had planned on using the Stargate to board Destiny when it was far out enough into the universe, but learned how to ascend before that time. In order to reach this ship, an address would have to be dialed consisting of nine chevrons, a possibility that had been unknown in the previous Stargate series.
The series begins when a team of soldiers and scientists from present-day Earth step through the Stargate to find the Destiny after their base is attacked. Many of its primary systems are damaged or failing, and they are unable to maneuver the ship or even return to Earth. However, the Destiny periodically stops to dial the Stargate to planets with necessary supplies to repair the ship. The writers have discussed the possibility that each season represents a voyage of the Destiny through a different galaxy.

The Stargates were created millions of years ago by an alien race known as the Ancients; their modern history begins when Egyptologist Daniel Jackson deciphers their workings in the Stargate film.
A Stargate is a portal device that allows practical, rapid travel between two distant locations. Within the Stargate fictional universe, Stargates are large rings composed of superconductors with nine "chevrons" spaced around their circumference. The inner ring, which rotates within the outer, contains thirty-eight unique symbols representing star constellations and one symbol representing the planet or point of origin. Pairs of Stargates function by generating an artificial stable wormhole between them, allowing one-way travel through. The symbols on the inner ring of the Stargate correspond to constellations and serve to map out coordinates for various destination planets. A typical Stargate measures 6.7 m (22 ft) in diameter, weighs 29,000 kg (64,000 lbs) and is made of the fictional heavy mineral "naqahdah".
