Definition
Meaning and Definition
A hypothetical subatomic particle, proposed in supersymmetry theories, which is the hypothetical superpartner of the graviton.
In theoretical physics, the gravitino is a fermionic particle that results from applying the principles of supersymmetry to the graviton, the hypothetical quantum of gravity. Its properties and potential detection are a major subject of study in cosmology and particle physics, particularly regarding dark matter candidates.

FAQ
Frequently Asked Questions
No, the gravitino is a hypothetical particle predicted by supersymmetry theories. It has not been experimentally observed.
A graviton is the hypothetical boson (integer spin) that mediates the force of gravity. A gravitino is its hypothetical fermionic superpartner (half-integer spin) in supersymmetry.
Certain models propose the gravitino as a candidate for cold dark matter. Its properties, like mass and stability, influence theories of the early universe and cosmic structure formation.
Practically never. Its use is confined to advanced discussions in theoretical physics and cosmology. It would be meaningless to most listeners in a general context.
A hypothetical subatomic particle, proposed in supersymmetry theories, which is the hypothetical superpartner of the graviton.
Gravitino is usually technical/scientific in register.
Gravitino: in British English it is pronounced /ˌɡravɪˈtiːnəʊ/, and in American English it is pronounced /ˌɡrævɪˈtinoʊ/. Tap the audio buttons above to hear it.

Mnemonic
Think: GRAVITon gets a twINO (a tiny twin) in supersymmetry – the GRAVITINO.
Conceptual Metaphor
Particle as a twin/counterpart (the fermionic 'shadow' or 'partner' of the bosonic graviton).
