Hyperspaces are typically defined as higher dimensional spaces that cannot be directly visualized or imagined using our three-dimensional perception. Referring to these spaces may require a selection of alternative synonyms such as higher dimensions, multi-dimensional space, non-Euclidean spaces, and higher dimensional worlds. Other suggested terms may include alternative space, parallel universe, hyperspace, beyond space-time, extra dimensions, and branes. These synonyms cater to both scientific and lay audiences and help to better clarify and explain the concept for those who may be unfamiliar with the technical term 'hyperspace'.
