Temporal distortion

A temporal distortion is a warp in the spacetime continuum, which can oftentimes be associated with the phenomenon of time travel. Temporal distortions can often be detected via tachyon particles, which are created as a side effect. 

Overview
In 2278, the USS Bozeman encountered a temporal distortion, causing it to travel forward in time to the year 2368, where it encountered the USS Enterprise (NCC-1701-D) in the area of space known as the Typhon Expanse. When the Bozeman collided with the Enterprise, the resultant explosion, being in close proximity to the distortion, ruptured the spacetime continuum, trapping both ships in a temporal causality loop wherein the Enterprise continually encountered the Bozeman and was subsequently destroyed. 

26th century time-pods produced detectable temporal distortions when traveling through time. Such a distortion was observed by the crew of the Enterprise in 2368, when a time-pod piloted by Berlinghoff Rasmussen arrived near their position. 

In 2368, while investigating an apparent temporal incursion into Earth's past by the Devidians, the Enterprise crew detected temporal distortions on the surface of Devidia II. Data's analysis indicated that the distortions were indicative of a synchronic distortion in which the Devidians were hiding. 

A temporal disruptor, a 29th century weapon, produced temporal distortions to fracture spacetime within a radius of 150 meters. Such a weapon was placed aboard the Starship Voyager in 2372, leading to Voyager's destruction in 2375. The crew of the 29th century Timeship Relativity recruited Seven of Nine from this time period to avert these events. This timeline was later negated when Seven, with assistance from Captain Kathryn Janeway from 2372, was able to stop the saboteur from planting the temporal disruptor on Voyager in the first place. 

In 2376, Kes traveled back in time to 2371 by drawing power directly from Voyager's warp core. Kes's arrival in the past produced temporal distortions resulting in the presence of tachyon particles throughout the ship. These particles caused Lieutenant Tuvok to experience a series of premonitions about the future, allowing the crew to prepare for Kes's arrival in five years time, and subsequently prevent her from traveling back in time in the first place.
