Definition
Meaning and Definition
A theoretical framework in physics that combines principles of supersymmetry with Einstein's theory of general relativity.
A class of field theories in theoretical physics and string theory where supersymmetry is a local symmetry, meaning the transformations vary in spacetime. It aims to unify gravity with the other fundamental forces by positing a 'gravitino' as the superpartner of the graviton.

Common Mistakes When Using “supergravity”
- Using it as a synonym for 'strong gravity' (e.g., 'The black hole has supergravity').
- Confusing it with 'superconductivity'.
- Attempting to use it in everyday comparative forms (e.g., 'more supergravity').
FAQ
Frequently Asked Questions
No, but it is related. Supergravity is one specific approach to formulating a quantum theory of gravity by incorporating supersymmetry. Not all quantum gravity theories are supergravity.
Not directly at present. Its energy scales are far beyond current particle accelerators. However, it makes predictions (like certain dark matter candidates) that could have indirect observational consequences.
In supergravity, the gravitino is the hypothetical fermionic superpartner of the graviton (the boson that mediates gravity). Its discovery would be strong evidence for supergravity.
Almost exclusively in very advanced, specialized textbooks, research papers, or documentaries on theoretical physics, string theory, or cosmology. It is not a general vocabulary item.

Supergravity is usually highly technical / academic / scientific in register.
Supergravity: in British English it is pronounced /ˌsuːpəˈɡrævɪti/, and in American English it is pronounced /ˌsuːpərˈɡrævɪti/. Tap the audio buttons above to hear it.

Memory Aids
Mnemonic
Think: SUPERsymmetry + GRAVITY = SUPERGRAVITY. It's gravity made 'super' by adding supersymmetric partners to its particles.
Conceptual Metaphor
Unifying tapestry: The theory is often metaphorically described as a framework that 'weaves together' the fabric of spacetime (gravity) with the symmetry of matter/force particles (supersymmetry).
