Are gravitons virtual or real.

    Maybe this thread should not be here.
    Are gravitons virtual or real. I've read that they are bosons, but... Also, are they expected to have momentum, virtual or otherwise?

    They can be, just as photons, both virtual and real. Einstein (or Pauli-Fierz) gravitons are massless.
