The Technology of the Ancients (Stargate Atlantis SGA)
37By the time they ascended, the Ancients had gathered more knowledge than any other known race. Even now, that knowledge is far superior to that of the Tau'ri, the Goa'uld, and the Wraith. Only Ori technology, created with ascended knowledge, and Asgard technology can compare and exceed in certain respects. Noted for its massive redundancies and the extensive use of Control crystals, Ancient technology is remarkably similar—in both appearance and function—to that of the Ori, as they both once lived together as one society: the Alterans. Ancient technology is also the most resilient ever seen, remaining intact for millions of years without even minor signs of deterioration or degradation of performance.
