  A correspondence between the $SO(5)$ theory of High-T${}_C$ superconductivity
and antiferromagnetism, put forward by Zhang and collaborators, and a theory of
gravity arising from symmetry breaking of a $SO(5)$ gauge field is presented. A
physical correspondence between the order parameters of the unified SC/AF
theory and the generators of the gravitational gauge connection is conjectured.
A preliminary identification of regions of geometry, in solutions of Einstein's
equations describing charged-rotating black holes embedded in deSitter
spacetime, with SC and AF phases is carried out.
