Physically the mass of the graviton would be shrinking right after Planck time and presumably it would be going to its equilibrium value of about 10-62 grams, for its present day value. It, graviton mass, would increase up to the Plank time of about 10-44 seconds. Note that the result that graviton mass shrinks to 10-62 grams for its present day value works only for relic gravitons. %K Heavy Gravity %K Plank Time %K Stress Energy Tensor %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=62304
