From the general assumption that gravity originates from the coupling and thermal equilibrium between matter and vacuum, we propose a self-consistent field equation including the quantum effect of gravity. As an application of this field equation, we give a natural and simple interpretation of the accelerating universe due to dark energy. Based on the idea that the dark energy originates from the quantum gravity effect of vacuum excitations due to the coupling between matter and vacuum, without any fitting parameter, the ratio between dark energy density and matter density (including dark matter) is calculated as 2.36, which agrees quantitatively with the result 7/3 obtained from various astronomical observations. Applying the field equation to a sphere full of superfluid helium, it is shown that with an atom interferometer placed in this sphere, the accuracy \Delta g/g below 10^(-8) could be used to test the quantum gravity effect, which satisfies the present experimental technique of atom interferometer.

I just found and thought it may be of interest to some.

Hmmm... at a glance it's interesting, but I need to do more than glance. Agreeing with observation is a good place to start however!
