In 24th century warp theory, a warp factor of 10 corresponds to an infinite velocity. Theoretically, a vessel traveling at Warp 10 would occupy all points in the universe simultaneously.
Although considered a theoretical impossibility at the time, Tom Paris of the USS Voyager reached the Warp 10 threshold in 2372, using shuttlecraft Cochrane which was equipped with an extraordinarily rare form of dilithium discovered earlier that year. After it was discovered that such travel induces hyper-evolution, the technology was discontinued after the initial test. (VOY: "Threshold")
- Many fans and even Paramount staff (including Rick Sternbach and Brannon Braga) discount the events of "Threshold", due to its severe scientific flaws.
