1305.0822 (Justin Khoury et al.)

On the Origin of Gravitational Lorentz Covariance    [PDF]

Justin Khoury, Godfrey E. J. Miller, Andrew J. Tolley
We provide evidence that general relativity is the unique spatially covariant effective field theory of the transverse, traceless graviton degrees of freedom. The Lorentz covariance of general relativity, having not been assumed in our analysis, is thus plausibly interpreted as an accidental or emergent symmetry of the gravitational sector.
