Gravitational interaction is a fundamental force of nature felt by leptons? (except, perhaps, the neutrino and quarks. Its exchange particle is thought to be the graviton (symbol g) though this has not yet been confirmed. |
Gravitational interaction is a fundamental force of nature affecting all particles, even the massless ones. Its exchange particle is thought to be the graviton (symbol g) though this has not yet been confirmed. A satisfactory quantum field theory of the gravitational interaction has yet to be constructed. |
