Hyperspace is a term used in science fiction and theoretical physics to refer to a dimension beyond the familiar three-dimensional space and one-dimensional time of the known universe. In science fiction, hyperspace often serves as a means of faster-than-light travel, allowing characters to traverse vast interstellar distances in a short period. The concept is sometimes translated to Hebrew as מרחב על-ממדי (mirkhav al-mimdai). In theoretical physics, the term can refer to the higher-dimensional spaces predicted by certain theories, such as string theory, which posits that the universe has more than the four dimensions of spacetime. In this context, hyperspace may describe the additional dimensions that are compactified or hidden from our everyday experience. The term is also used in mathematics to describe spaces with more than three dimensions, which are studied in various branches of geometry and topology. The concept of hyperspace has captured the imagination of scientists and science fiction enthusiasts alike, bridging the gap between theoretical exploration and creative storytelling.
