* Idea: (A.k.a.
doubly-general relativity) A class of theories generalizing doubly-special
relativity to incorporate curvature, which leads to an energy-dependent
metric, connection and curvature, and a simple modification to Einstein's
equation; Its phenomenlogy includes modified dispersion relations, with
field excitations propagating with different energy-momenta perceiving
different background geometries.

* Cosmology: 2015,
There have been claims that the initial singularity might be avoided,
but recent more careful results are inconclusive.
