Rainbow Gravity  

In General > s.a. spacetime models [emergent spacetime].
* 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.

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