It implies that the graviton becomes massive at curvature radii less than the Hubble radius until at the Planck length it becomes a Planck mass Black Hole. If you Divide the Hubble radius by the Planck length you get 10^60 Eigen states that the graviton can assume. Thus the Planck radius is the UV cut off Stuart https://www.blogger.com/profile/12767480095489975264noreply@blogger.comtag:blogger.com,1999:blog-22973357.post-38654545854626760272014-10-07T09:53:03.799-04:002014-10-07T09:53:03.799-04:00I guess,

My opinion is, the future colliders will just increase the noise/signal ratio of experimental data, but it will not bring any substantial progress.
