The AWT can be interpreted as a extrapolation of 1D particle theory in 10-24 dimensions (i.e. string theories) to theory of zero-dimensional particles in infinite-dimensional space-time, i.e. into Aether. The quantum gravity (QG) theory can be considered as dual quantum field theory to string theory (ST) in certain extent, while still being slightly more general then ST, being based on general relativity, instead of special relativity, like ST. Which theory should be dual to Aether theory, after then?
By my opinion the most promising candidate should be generalized geometrodynamics, introduced by J.A. Wheeler in the mid of 50th of the last century. Geometrodynamics is general relativity based concept, which describes Universe in terms of space-time deformations. If we realize, all particles in AWT are formed by Aether density fluctuations, we can say, material particles are formed by space-time curvature and whole universe can be described in terms of nested space-time curvature and acceleration instead of mass/energy density field.
From geometrodynamics theory the Universe existence follows from omni-directional Universe expansion, which in its consequence leads to the formation of local and global event horizons, i.e. particles and gravity phenomena. While the quantum mechanics neglects the expansion of probability function (wave packets of particles) due the gravity (the existence of gravity cannot be derived from quantum mechanics), a classical geometrodynamics neglects the gravitational collapse of geons into singularities due the expansion of Universe.
The omni-directional Universe expansion/collapse prohibits both the expansion of wave packets into infinity from internal perspective, both the collapse of geons into singularities from internal perspective, so we can see, the gravity is a direct manifestation of Universe expansion and the gravity force as an acceleration force at the presence of space-time curvature.
