Phenomenology of Higher-Dimensional Gravity  

In General > s.a. einstein-cartan theory; fifth force.
* Idea: These theories lead to departures from Newtonian r−2 behavior at some scales; Also, models with extra dimensions tipically produce a 4D effective theory whose vacuum is not exactly Lorentz invariant, but can be considered a physical medium whose refractive index is determined by the gravitational field.
* Bounds: 2007, Size less than 80 microns, from the age of the black hole XTE J1118+480; 2018, The strictest limits yet on the size of extra dimensions come from the fact that evaporating black holes haven't destroyed the universe.
