[gravit(ation) + –on.]

Examples

  • Accordingly one attempts to treat the gravitational field as consisting of quantum - mechanical particles to which the name graviton has been given.

    RELATIVITY

  • Some, mostly string theorists, posit the existence of a massless particle they've dubbed the graviton and claim that it is responsible for mediating the force of gravity, a force that has unlimited range.

  • For this reason the putative quantum particle of a gravity wave, called the graviton, is said to have an intrinsic spin of two.

    A Dark, Misleading Force

  • So imagine we have a certain kind of particle called a graviton -- that's the kind of debris we expect to be ejected out if the extra dimensions are real.

  • This in effect corresponds to a giant graviton, which is required to "punch" a temporal hole to allow us to travel from the here-and-now to the if-and-when.
