Temporal energy

Temporal energy was a force which could be closely related to instances of time travel. Temporal energy could take many forms, such as the Nexus energy ribbon, which was a confluence of temporal energy, or as a radiative energy produced by quantum singularities. 

Overview
''In 2370 in an alternate timeline, temporal energy was emitted in great quantities from an anti-time eruption in the Devron system. Exposure to this energy caused the crew of the USS Enterprise (NCC-1701-D) to experience symptoms of temporal reversion, such as the healing of old scars. The timeline in which these events took place was negated when Captain Picard was able to prevent the formation of the eruption from occurring.''

In 2371, an exploding microscopic singularity passing through the Sol system emitted a surge of temporal energy which shifted chroniton particles lodged in the USS Defiant (2370)'s ablative armor matrix into a high state of temporal polarization. This caused a transporter beam passing through the polarized particles carrying Captain Benjamin Sisko, Lieutenant Jadzia Dax, and Doctor Julian Bashir, to be redirected through time, causing them to materialize in San Francisco, the year 2024. 

Later that year, the temporal energy being emitted by the artificial quantum singularity of a cloaked Romulan Warbird interacted with the delta-series radioisotopes in Chief O'Brien's body, which he had absorbed as the result of an explosion of a plasma conduit. This had the effect of transporting O'Brien five hours into the future every time the singularity emitted temporal energy at a specific wavelength. Later, O'Brien and Doctor Bashir were able to control his time shifts by calibrating the isotopes' decay rates to match the temporal frequency of the singularity, thereby allowing O'Brien to travel three hours into the future and uncover a Romulan plot to destroy the station. 

''In another alternate timeline, a Krenim weapon ship produced powerful spacetime shock waves composed of temporal energy, which altered history as they propogated through space. These shock waves were the results of temporal incursions initiated by the weapon ship's master, Annorax, who used the weapon to erase objects from history in an attempt to manipulate the timeline. This timeline was negated in 2374 when, as a result of massive battle damage, a temporal incursion was initiated within the weapon ship itself, erasing it and all of the damage it did to the timeline from history.''
