Luigi I believe that gravitons exist. I believe "virtual" particles
exist. The neutrino was theorized long before it was discovered. Now we
are trying to show they make up most of our universe's mass(go figure) I
need the graviton to make my "Spin is in" theory work for gravitation.
Luigi I have no problem unifying the 4 forces,because I have always
known the other three were created by gravity. Bert
