- Some theories that unify gravity with the other forces predict that fundamental constants like the proton-to-electron mass ratio could vary over cosmic time. If they do, then the laws of physics aren't permanent. Measurements of single ions now yield new upper limits on such variations. http://physics.aps.org/articles/v7/117 81 comments science
