hyperspace: /hi:´per·spays/, n.

A memory location that is far away from where the program counter should be pointing, especially a place that is inaccessible because it is not even mapped in by the virtual-memory system. “Another core dump — looks like the program jumped off to hyperspace somehow.” (Compare jump off into never-never land.) This usage is from the SF notion of a spaceship jumping into hyperspace, that is, taking a shortcut through higher-dimensional space — in other words, bypassing this universe. The variant east hyperspace is recorded among CMU and Bliss hackers.
