Hyperspace

From Fancyclopedia 2, ca. 1959

Literally a space of more than three dimensions; conventionally, what you traverse when you go thru a space warp. Practically, it's the same thing as subspace: an imaginary miniature universe in which inconvenient natural laws like the light-speed limit on velocity need not apply. And John Magnus once organized a group of this name, the Hopeful Young People's Extra Radical Society for Promoting Amiable Conditions Everywhere.

The term’s use in sf goes back at least to 1928, when Kirk Meadowcroft used it in “The Invisible Bubble” in the September Amazing Stories.
