This entry is about the concept in gravity/cosmology. For the concept in supergeometry see at superspace.

Idea

In describing gravity (general relativity) on globally hyperbolic spacetimes as evolution along a given foliation by spacelike slices, the Einstein equations describe a 1-parameter evolution in a configuration space/moduli space of fields on each time slice. For applications to cosmology this space may be drastically reduced to retain only some very large scale feature. The resulting configuration space had been called “superspaces” by John Wheeler.
