Mass for the graviton
Can we give the graviton a mass? Does it even make sense to speak of a massive graviton? In this essay I shall answer these questions in the affirmative. I shall outline an alternative to Einstein Gravity that satisfies the Equivalence Principle and automatically passes all classical weak-field tests (GM/r ≈ 10). It also passes medium-field tests (GM/r ≈ 1/5), but exhibits radically different s...
متن کاملPhoton and Graviton Mass Limits
Efforts to place limits on deviations from canonical formulations of electromagnetism and gravity have probed length scales increasing dramatically over time. Historically, these formulations have passed through three stages: (1) Testing the power in the inverse-square laws of Newton and Coulomb, (2) Seeking a nonzero value for the rest mass of photon or graviton, (3) Considering more degrees o...
متن کاملGraviton Mass or Cosmological Constant?
To describe a massive graviton in 4D Minkowski space-time one introduces a quadratic term in the Lagrangian. This term, however, can lead to a readjustment or instability of the background instead of describing a massive graviton on flat space. We show that for all local Lorentz-invariant mass terms Minkowski space is unstable. We start with the Pauli-Fierz (PF) term that is the only local mass...
متن کاملGeneral Ether Theorie and Graviton Mass
We introduce additional restriction into ”general ether theory” a generalization of Lorentz ether theory to gravity which fixes the signs of the cosmological constants in this theory. This leads to an oscillating universe, thus, solves the cosmological horizon problem without inflation. We prove the equivalence of the Lagrangian of this theory with Logunov’s ”relativistic theory of gravity” wit...
متن کاملBounding the mass of the graviton using eccentric binaries
We describe a method by which gravitational wave observations of eccentric binary systems could be used to test General Relativity’s prediction that gravitational waves are dispersionless. We present our results in terms of the graviton having a non-zero rest mass, or equivalently a non-infinite Compton wavelength. We make a rough estimate of the bounds that might be obtained following gravitat...
