Real space (or the Real)[1] is the three-dimensional[2] domain of a universe containing baryonic matter and the conditions to create life.


The skein is how real space appears in hyperspace.[3] The skein is a two-dimensional plane representing space-time.[4] It is also the surface of a hypersphere, with the hyperspace within being infraspace and ultraspace being that without.[5]


A warp is a disturbance on the skein. Gravity wells create warps.[6] They may be artificially induced, such as by warp units, for a variety of purposes.[7]
