Event horizon
From Memory Alpha, the free Star Trek reference
- This page is about the astronomical phenomena; for the film, see Event Horizon.
An event horizon is the boundary of a black hole, or any number of other quantum singularities, at which the escape velocity equals the speed of light and beyond which no measured velocity is sufficient to overcome the event's gravitational pull.
The immense gravity required to generate an event horizon is sufficient to significantly distort both space and time.
The outer event horizon of the Barzan wormhole was penetrated by the type 15 shuttlepod Ley in early 2366 by Data and Geordi La Forge. (TNG: "The Price")
A cosmic string emanates a characteristic set of subspace frequencies as atomic particles decay along its event horizon. (TNG: "The Loss")
In 2371, the USS Voyager was trapped on the event horizon of a type-4 quantum singularity. During this period it was possible for Voyager to observe a duplicate version of itself that was being projected through time due to parallax distortion of the space-time continuum. (VOY: "Parallax")
