Warp barrier
The warp barrier, also known as the light barrier, was the transition from sublight velocities to faster-than-light warp speeds. It was also used as a reference to the limits of warp drive technology to achieve certain rates of speed.

In 2063, the Phoenix reached the warp threshold and broke the warp barrier. ()

In 2143, the  prototypes broke the warp 2 barrier. ()

In 2254, when the crew of the  discovered what they thought were survivors from the , which had crashed on Talos IV in 2236, José Tyler noted that the survivors would not believe how fast they could get back to Earth, due to the breaking of the "time barrier" that had occurred since the Columbia had crashed. ()

In 2364, after a series of formula modifications by Kosinski, the  experienced a phenomenal surge of  during a warp speed experiment and jumped over millions and later over a billion light years through space in a matter of minutes. During the first jump, instrumentation indicated that the ship actually surpassed warp 10, apparently making the so-called warp 10 barrier meaningless. Kosinski declared that science would need new definitions and new parameters to define warp speed. One suggestion was the Kosinski scale. It was later determined that the enormous surge of speed was caused by The Traveler and that Kosinski's formulas were bogus. () The Traveler had the ability to alter warp fields using the energy of his thoughts to move through space and time. ()

In 2372, the warp 10 maximum warp barrier was also known as the transwarp threshold. ()
