hyperspace /hi'per-spays/ n. A memory location that is *far* away from where the program counter should be pointing, often inaccessible because it is not even mapped in. "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.
