Graviton beam

A graviton beam is a confined beam of gravitons.

A graviton beam could be emitted through a starship's deflector dish. This was implemented on board the USS Voyager in 2374 when Seven of Nine modified Voyager's navigational controls to allow the deflector to emit a resonant graviton beam that opened a portal to fluidic space. A heavy graviton beam was considered and rejected as a weapon against the Borg by the USS Enterprise (NCC-1701-D) in 2366.
