Spacetime
In physics and mathematics, spacetime, or more fully as the spacetime continuum, is the singular continuum in which three-dimensional space and the singular dimension of time co-exist. 

When a starship reaches the speed of warp 10, it goes into subspace and exists at every point in space at once, in superposition. () Exceeding warp 10 would allow a starship to travel backwards in time. ()

According to Spock, "In order to function, the galactic creation point must extend through space, time, into another dimension where the logic of things is totally different." ()

The Krenim weapon ship, used by Annorax, worked by pushing the target outside the spacetime continuum, thus deleting it from history. ()

Disruption to the spacetime continuum can have serious repercussions. In 2368, for example, the  unknowingly entered a rupture in the spacetime continuum, which threw the ship and its crew into a temporal causality loop, experiencing the same time frame over and over. ()
