Slipspace translocation
From Halopedia, the Halo wiki
Teleportation is a method of travel that allows the user to travel nearly instantaneously between locations. This is achieved through the use of slipspace as a travel medium, much like the principles behind the UNSC's Shaw-Fujikawa Translight Engines or the Covenant's Slipspace Drive. The Forerunners were the first known civilization to make extensive use of teleportation technology. Later on, this technology was reverse-engineered by the Covenant.
