supergravity Scientific  

/ so̅o̅′pər-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

Example Sentences

Dr. Deser worked with Bruno Zumino, one of the originators of supersymmetry, to add gravity to the theory, creating the theory of supergravity.

From New York Times

Supergravity is also a key aspect of superstring theories, which attempt to provide a complete explanation of how the universe works, overcoming shortfalls of quantum gravity theories.

From New York Times

He and Dr. Zumino published a paper about supergravity in June 1976.

From New York Times

However, another group of physicists — Daniel Freedman, Sergio Ferrara and Peter van Nieuwenhuizen — beat them to the punch, describing supergravity in a paper that had been completed about a month before Dr. Deser and Dr. Zumino submitted theirs.

From New York Times

Supergravity includes gravitons — the gravitational equivalent of photons — and adds a supersymmetric partner, the gravitino.
