Meaning and Definition
A hypothetical elementary particle that mediates the force of gravity.
In theoretical physics, the quantized carrier particle of gravitational interactions, predicted by models attempting to reconcile general relativity with quantum mechanics. The concept is sometimes used figuratively in science fiction or popular science to personify gravity.

FAQ
Frequently Asked Questions
No, the graviton is a hypothetical particle. It is predicted by theories but has not been observed experimentally.
Theoretical models predict the graviton would be a massless particle with a spin of 2.
Yes. The word is a blend of 'gravity' and the suffix '-on', which is commonly used for elementary particles (e.g., proton, electron).
Only in very specific contexts, like discussing popular science or theoretical physics. It is not a common word in general conversation.

Graviton is usually highly technical/scientific, academic, science fiction (figurative use). in register.
Graviton: in British English it is pronounced /ˈɡræv.ɪ.tɒn/, and in American English it is pronounced /ˈɡræv.əˌtɑːn/. Tap the audio buttons above to hear it.
Learning
Memory Aids
Mnemonic
Think: GRAVity + -ON (like protON, electrON). It's the particle 'on' which gravity rides.
Conceptual Metaphor
THE FORCE CARRIER METAPHOR: Gravity is conceived as an interaction transmitted by an exchange of particles (gravitons), like a game of catch transmitting a push.
