LOL, no they're not. But only because I haven't fully explored Kaluza-Colyer theory! :-)
What's Horava Gravity? Read here:
From Wikipedia, the free encyclopedia
Hořava-Lifshitz gravity (or Hořava gravity) is a theory of quantum gravity proposed by Petr Hořava in 2009. It solves the problem of different concepts of time in quantum field theory and general relativity by treating the quantum concept as the more fundamental so that space and time are not equivalent (anisotropic). The relativistic concept of time with its Lorentz invariance emerges at large distances. The theory relies on the theory of foliations to produce its causal structure. It is related to topologically massive gravity and the Cotton tensor. It is a possible UV completion of general relativity. The novelty of this approach, compared to previous approaches to quantum gravity such as Loop quantum gravity, is that it uses concepts from condensed matter physics such as quantum critical phenomena. Hořava's initial formulation was found to have side-effects such as predicting very different results for a spherical Sun compared to a slightly non-spherical Sun, so others have modified the theory. Inconsistencies remain.
Amazingly, Hořava-Lifshitz gravity seems tailor made for Bohmian Mechanics. Together, they give the first and only self-consistent philosophical framework to reconcile quantum mechanics' intrinsic non-locality with gravity's low-energy effective symmetry: Lorentz invariance.
