Tetryon A tetryon is a subatomic particle that can only exist in subspace environments . Tetryon radiation is a bombardment of these particles . Since these particles are a property of subspace , they become highly energetic and unstable when they are extruded into normal space , which can occur by both natural and artificial means . Tetryons have a random momentum , and thus cannot be tracked by sensor s . In 2369 , solanogen - based lifeform s from a tertiary subspace manifold used a stream of spatially inverted tetryons to open a spatial rupture between their native realm and the . This allowed them to abduct several " Enterprise " crew members for experimentation . ( ) Later that year , Dr . Beverly Crusher investigated the death of Dr . Reyga , a Ferengi scientist . Jo ' Bril , a Takaran scientist who piloted the " Justman " into the star Veytan to test Reyga ' s metaphasic shield , was supposedly killed after the " Justman " s shields failed . Crusher wanted to know if Jo ' Bril was exposed to a tetryon field inside the shuttle , as it would have left residual traces in his system . Crusher did find traces of tetryons in his system , convincing her that someone sabotage d the shields on the shuttle . ( ) Intense tetryon fields , such as those surrounding the Hekaras Corridor , pose a hazard to spacecraft . ( ) Bombardment with tetryons can render directed - energy weapons inoperative . Jadzia Dax utilized tetryons to disable the weapons of The Albino ' s troops on Secarus IV in 2370 . ( ) In 2370 , Odo theorized that a weapon used by Trazko to shoot Quark was tetryon - based , to avoid activating the weapon detection scanner s on the Promenade of Deep Space 9 . Doctor Bashir noted that this was consistent with Quark ' s injuries . ( ) The used a coherent tetryon beam to scan starships before dragging them to the Delta Quadrant with a displacement wave . ( ) In 2371 , Jadzia Dax scanned the area around Deep Space 9 and did not find anything at first . However , after scanning on a lower subspace bandwidth , she discovered low - level tetryon emissions . This was discovered to be a quantum singularity . ( ) Later on , Commander Benjamin Sisko informed Chief Miles O ' Brien that sensors had discovered high concentrations of tetryon particles moving towards Deep Space 9 . Suddenly , a Cardassian ship decloaked and went into the Bajoran wormhole heading for the Gamma Quadrant . ( ) Later that year , Dax found a sabotage device located in a warp plasma conduit on the . In trying to find out who the saboteur was , Dax said that whoever committed the sabotage would have been exposed to trace elements of tetryon particles . ( ) " In an alternate timeline , Harry Kim and Tom Paris stole the runabout and had a vessel on their tail . Kim was able to elude them for a short time by venting tetryon plasma from the " Yellowstone " s nacelles . The tetryon plasma emitted multiflux gamma radiation , which disrupts subspace . The plan was successful in stalling the " Nebula " - class vessel ' s engines . " ( ) In 2372 , tetryon pulse echoes were used to navigate the highly unstable atmosphere of a gas giant . However , course modifications were required after each pulse in order to avoid detection . This meant that the random momentum to avoid being tracked by sensors was invalid when emitted as a pulse . ( ) In 2373 , the infant Changeling given to Odo by Quark was suffering from tetryon radiation . ( ) Later that year , Harry Kim detected a tetryon surge from a Nasari ship and interpreted it as a sign they were about to attack , due to a " hunch " caused by his exposure to a Taresian retrovirus . He was later found to be right , as Nasari particle beam weapons are tetryon - based . ( ) Later that year , traveled through a region of heavy tetryon radiation . Lieutenant Tuvok enhanced the ship ' s shields to compensate . ( ) The atmosphere inside a Borg cube contains tetryon particles . ( ) In 2375 , Captain Jean - Luc Picard took several weapons with him from the before leaving for the Ba ' ku planet to fight the forced relocation of the Ba ' ku , including seven metric tons of ultritium explosives , eight tetryon pulse launchers and ten isomagnetic disintegrator s . ( ) The weapon s of Qatai ' s ship are tetryon - based . In 2375 , Qatai used them to initiate an electrolytic reaction in a burst of antimatter ejected from " Voyager " s nacelle s . This caused the telepathic pitcher plant to regurgitate both ships . ( ) The Nacene generated power with the use of tetryons . ( ) In 2377 , " Voyager " struck a subspace mine . This lead to the ship being flooded with tetryon radiation , and most of the crew suffering radiation poisoning as a result . With The Doctor only able to stabilize the condition of the crew at best until the radiation could be purged , Captain Janeway was forced to order the ship abandoned . Before leaving , Janeway left The Doctor , as the Emergency Command Hologram , in command of " Voyager " . The Doctor was eventually able to vent the radiation . ( ) The energy barrier that isolates the territory of the Ventu on Ledos has a distinct tetryon signature . The Borg had previously encountered the technology in Species 312 . The barrier left a distinct tetryon flux on debris from a " Voyager " shuttlecraft that crashed into it in 2378 . Seven of Nine was able to construct a tetryon - based signaling device to open the energy barrier briefly from the remains of a Class 2 shuttle . ( ) Apocrypha . In the game " Star Trek Online " , tetryon - based energy weapons were available to characters of rank commander and higher . Their special ability was a 2 . 5 % chance to inflict additional shield damage . They were depicted in the game appearing as azure blue energy .
