A continuum may refer to any of the following:
1. In mathematics, the term continuum refers to the set of real numbers. The cardinality of the continuum is the "size" of this set. Technically, this size is infinity, but this infinity may be larger or smaller than other infinite sets of numbers. This notion of "relative infinity" is defined by a theory called the continuum hypothesis.
2. The Continuum is an online, turn-based role-playing game written in Adobe Flash.
3. Continuum is the PC version of Alpha Waves, a game for the Amiga and Atari ST computers, first released in 1990. Often credited as the first 3D game for the PC, its graphics engine was the inspiration for another popular PC game, Alone in the Dark.
