The Q Continuum

The Q Continuum are a extradimensional plane of existence inhabited by a race of beings known as the Q. The term could also refer to the Q society itself. As a race, the Q are immortal, but not absolutely omniscient or omnipotent, just possessing the ability of instantaneous matter-energy transformation and teleportation, as well as the ability of time travel. Their apparent abilities included moving entire asteroid belts and stars, creating alternate timelines, and affecting universal states of nature such as the gravitational constant. In fact, the only time a Q was seen as unable to do something was during a period where their powers are reduced or revoked by the Continuum.
