Temporal field A temporal field was an energy form which had been closely related to instances of time travel . Known to be created both naturally and artificially , temporal fields could be dispersed by exposure to tachyon particle s . ( ) Overview . Temporal fields were utilized by 29th century timeship s to create temporal rift s . Created by a temporal field generator , the stability of such a field was determined by the proper calibration of the vessel ' s temporal matrix . In an alternate timeline in 1996 , 20th century industrialist Henry Starling utilized the stolen timeship " Aeon " to travel into the future , but the instability of the temporal field he generated caused a massive temporal explosion in the 29th century , destroying all of Earth ' s solar system . This timeline was later negated by the crew of the , who were able to destroy the " Aeon " moments before it entered the rift . ( ) In 2373 , while trapped in an illusion by an unknown alien , Captain Janeway came to believe she had become trapped in a temporal loop . In an attempt to disrupt any temporal field which might be causing the loop , Janeway initiated a tachyon burst from a shuttlecraft . ( ) " In another alternate timeline in 2374 , " Voyager " generated a temporal field in the form of temporal shielding , which protected the ship from the alterations to the timeline initiated by Krenim scientist Annorax using his weapon ship . This anomalous temporal reading was enough to throw off Annorax ' s calculations when planning a temporal incursion , causing him to inadvertently revert the Krenim Imperium to a pre - warp state . The timeline in which these events occurred was negated 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 " . ( ) The time portal discovered on the Bajoran colony world of Golana later that year utilized a temporal field for allowing objects to travel through time . After eight - year - old Molly O ' Brien fell through the portal , arriving three hundred years in the past , her father , Miles O ' Brien , Deep Space 9 ' s chief of operations , was successfully able to modulate the portal ' s temporal field generators in order to re - establish the field , and retrieve Molly using a transporter beam . ( ) A unique planet discovered in the Delta Quadrant by the " Voyager " crew in 2376 produced a powerful temporal field , a result of the planet possessing a tachyon core . The field manifested itself in the form of a temporal differential between the planet and the surrounding space , the passage of one day on the planet corresponding to 1 . 03 seconds as experienced on " Voyager " . The crew developed a plan whereby The Doctor would beam to the surface on an information - gathering mission for three seconds , giving him almost two days to gather data . However , when they attempted to beam him back , the temporal field interfered with the transporter ' s confinement beam , preventing the crew from retrieving him . Eventually the crew was able to reinitialize the containment beam and transport The Doctor back , after he experienced nearly three years on the planet . ( )
