  • n. A hypothetical particle postulated to be the quantum of gravitational interaction and presumed to have an indefinitely long lifetime, zero electric charge, and zero rest mass. See Table at subatomic particle.

  • n. A hypothetical gauge boson that regulates the gravitational force. It would have a spin of 2 and zero rest mass.

  • n. A theoretical gauge boson that mediates the (extremely weak) gravitational interactions between particles; the quantum of the gravitational field, having zero rest mass and a spin of 2.

gravit(ation) + -on1.


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


  • 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.

    Michael Zimmerman, Ph.D.: Gravity, Evolution and Religious Dogma

  • 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.

    Brian Greene on string theory

  • 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.

    Damn Interesting

  • In physics, the "graviton" is a hypothetical elementary particle that mediates the force of gravity in the framework of quantum field theory.

    American Chronicle

  • Additionally, you can enhance your ship with station modifications, which can all previously be seen in movies and TV shows, for example graviton generators.

  • The first step, then, is to let go of a literal vision of God, and to begin to know that the search for God is more akin to the search for love and connection than the search for a graviton or Big Foot.

    Rabbi Alan Lurie: Why Does God Hide?

  • A graviton wouldn't do the job even if I accepted RQFT, but a monopole of some variety would.


  • I don't buy the graviton thing, and it is for all intents and purposes an unfalsifiable extrapolation based on a priori commitment to a standard model I rejected decades ago because it's not just 'incomplete', it's flat-out wrong.
