* Idea: A non-relativistic
renormalisable theory of gravitation which reduces to Einstein's general
relativity at large distances but violates Lorentz
invariance at small distances and introduces anisotropic spacetime scaling; Proposed
as a candidate for a UV completion of Einstein's theory.

Phenomenology In General > s.a. gravitational
thermodynamics; graviton.
* In general: The post-Newtonian
coefficients coincide with those of general relativity, so the deviations
from general relativity can be tested only in strong-gravity regimes; In
its original version, the theory has a non-zero cosmological constant of
the wrong sign.
