This entry is about the concept in supergeometry. For the concept in gravity/cosmology see at Wheeler superspace. superalgebra and (synthetic ) supergeometry Physicists often refer to spaces in supergeometry, such as supermanifolds or super schemes, as superspaces. Hence a superspace can be an affine superspace (the affine counterpart of the super vector space over real or complex numbers), superscheme, supermanifold, etc. Mostly however “superspace” is used for superspacetimes, and here mostly.
