Gravity well A gravity well is a distortion of the space - time continuum caused by an object with mass , which can be conceptualized on a two - dimensional surface as a depression : the " well " . The curvature of the well corresponds to gravity . In 2155 in the mirror universe , the Tholian s detonated a tricobalt warhead in the gravity well of a dead star , which created an interphasic rift into another universe in the future of 2268 . ( ; ) In 2258 of the alternate reality , the starship became caught in the gravity well of a black hole created by the explosion of a massive amount of red matter when the " " crashed into the " Narada " . Fortunately , the " Enterprise " managed to escape the gravity well after ejected the ship ' s multiple warp core s and detonated them , creating a large blast wave that pushed the ship out of danger . ( ) The Bajoran wormhole had its own gravity well . After a carrier wave emitted from the newly - established wormhole relay station created a subspace inversion in the wormhole in 2371 , its gravity well increased by a factor of three . ( ) In 2368 , Wesley Crusher and the Nova Squadron flew in a diamond slot formation around Saturn and came out of the gravity well of Saturn ' s moon Titan , shortly before the Squadron suffered a catastrophic accident after attempting the dangerous maneuver Kolvoord Starburst , which claimed the life of Joshua Albert . ( ) The Dyson sphere had an immense gravity well , not least due to the star at its center but the mass of the structure itself . As no radiant sunlight light or solar wind escaped from the sphere , starships were not able to detect the sphere until they were almost on top of it . As a result the sphere ' s gravity well came as quite a shock to both the in 2294 and in 2369 , so much so that the former was pulled in and crashed on the surface . ( ) Later on , in a holodeck simulation , a holographic took control of the " Enterprise " - D and the ship became trapped in the gravity well of a gas giant in the Detrian system . To fool Moriarty into releasing the voice commands and regain command , Jean - Luc Picard created a holographic program , Picard Delta One to make Moriarty think he had left the " Enterprise " on the shuttlecraft " Sakharov " . ( ) In 2369 , two quantum singularity lifeform s came into this space - time continuum to save their young who were trapped in an artificial gravity well , the engine core of the Romulan warbird . The aliens needed a natural gravity well to incubate their young and thought the engine core was a natural one . ( ) In 2370 , Commander Benjamin Sisko ordered Gideon Seyetik to turn his shuttlepod around and return to the . Seyetik told Sisko that it was told late , as he had entered the gravity well of the dead star Epsilon 119 . He later died after his shuttlepod crashed on Epsilon 119 , but the star was re - ignited with the use of protomatter . ( ) In 2374 , Tuvok and Seven of Nine were captured by the Hirogen . However , the ship they were on was slowly being sucked in by a black hole . On the , the crew tried beaming them off but Harry Kim warned Kathryn Janeway that the gravity well from the black hole could scatter their patterns . Janeway saw no other choice and was ulitmately successful in beaming them onto " Voyager " . ( ) It was also possible that while a planet may be found inside a rift that has the properties of a gravity well , the gravity on the planet ' s surface may be similar to Earth ' s . Tom Paris and Tuvok were stranded on such a planet while USS " Voyager " was nearly pulled inside a rift containing the planet in 2375 . Tuvok and Paris were later rescued . ( )
