Gravitons interact with each other in quantum gravity models.
the verdict
SUPPORTED
the evidence backs this
confidence 84/100
Quantum gravity models and effective field theories of gravity explicitly feature self-interaction terms among gravitons, such as cubic and quartic vertices that lead to graviton-graviton scattering.
