supergravity Scientific  
/ so̅o̅pər-grăv′ĭ-tē /
  1. 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.


Etymology

Origin of supergravity

First recorded in 1975–80; super- + gravity
