Could someone help me with this physics question? (Gravity and Exchange Interactions)

  1. Mar 13, 2006 #1
    Can gravity be explained by exchange interactions?

    I am supposed to give a presentation on it, so some explanation as to why or why not would also be very much appreciated.

    Thanks very much in advance.

    Of course it can. That's the whole idea behind an intracting quantum field theory. Introducing mediators (bosons) which allow interactions not only between matter particles, but also between themselves. The latter are called self-interacting theories. Gravity is such an example. Gravitons interact with each other.
