This document is due to a question asked in the Dark Side of the Universe conference, 2010, in Leon, Mexico, when a researcher from India asked the author about how to obtain a stability analysis of massive gravitons. The answer to this question involves an extension of the usual Pauli_Fiertz Langrangian , with non zero graviton mass contributing to a relationship between the trace of a re done GR stress-energy tensor ( assuming non zero graviton mass) , and the trace of a re done symmetric tensor , times a tiny mass for a 4 dimensional graviton. The resulting analysis makes use of Visser's treatment of a stress energy tensor, with experimental applications discussed in the resulting analysis. If the square of frequency of a massive graviton is real valued and greater than zero, stability can be possibly confirmed experimentally.
Comments: 6 pages, no figures. Part of accepted contribution to the Frontiers of Fundamental physics 11 conference, Paris, as a poster. Will be part of questions raised in documentation for the DICE 2010 conference in Italy run by Thomas Elze, September 13-17, 2010
