This enormously broad sf theme is dealt with under several encyclopedia headwords, of which the most important is Time Travel. Physical travel through time is traditionally accomplished either by imaginary Technology in the form of a Time Machine, through the more or less "natural" accident of a Timeslip, or via a fixed-position Time Gate which may be either natural or artificial. Heedless use of time machines may – depending on the nature and stability of the fictional universe – lead t...
