Do Gravitons Attract Other Gravitons?

  1. Jun 5, 2009 #1
    As the title suggests, I'm wondering if gravitons feel the pull of other gravitons. And secondly, if a singularity emits gravitons, how do the gravitons get out of the event horizon to pull in other matter?

    Yes they do. The question is equivalent to asking whether gravity gravitates and the answer is yes.

    Sometimes we ignore this effect (b/c if its self interaction its going to be loop supressed and small in a flat background) but it has to be there in the full picture and this sort of physics does become important at some scale..

    It doesn't. A gravitating object does not emit gravitons, just as a charged object doesn't glow (emit photons).

    the fact that gravity IS self interacting made it's formulation difficult,,,via Einstein's tensor.


    Gravity is present before the event horizon forms. Once the star, for example, collapses beyond the critical circumference where the event horizon forms, only random radiation leaks out....via virtual particle formation just outside the horizon....

    Does this imply that the gravitational field once formed is frozen? What about the evidence that Jupiter's field changes with its motion and moves at the speed of light? What about the possibility that gravitons are virtual and exist for only an instant?
