Hyperspace

[Drimar]

Can you please tell me what it is ? I know linear space but don't know hyperspace. What will belong to hyperspace ?

Hyperspace is a space of more dimensions than the four of spacetime; in various theories of physics it is conjectured that we live in such a hyperspace, and that our "familiar four" are just some of a true number of 10 or 11 dimensions, say.
