Subspace was the medium used for long-range communications such as subspace radio and subspace transponders. It was a distinct dimension from realspace, like hyperspace and otherspace.[1]

Behind the scenesEdit

In Star Trek, subspace is both the primary form of radio communication used by Starfleet, and the analog to Warp, which creates subspace bubbles around ships, allowing faster-than-light travel. Messages sent through subspace can bypass the physical light-speed limitations of real space, allowing for near-instantaneous communication in the Star Trek universe.

Subspace also appears in the Stargate series as the analog to the hyperspace dimension. Subspace has been seen as an element of faster-than-light travel on a number of occasions.
