su·per·grav·ity (s  p r-gr v  -t )n. The part of supersymmetry theory that attempts to merge the theory of gravity with the other fundamental forces by postulating the graviton's supersymmetric partner, the gravitino. |
supergravity [ˌsuːpəˈgrævɪtɪ]
n
(Physics / General Physics) Physics any of various theories in which supersymmetry is applied to the theory of gravitation
| supergravity (spr-grv-t) A quantum field theory that combines general relativity with supersymmetry in order to unify gravity with the other fundamental forces of nature. Supergravity predicts the existence of the graviton as a carrier for the force of gravity, as well as a corresponding particle called the gravitino, neither of which have been observed experimentally. |
