Speed Limit on the brane
arXiv:hep-th/0603235 · doi:10.1209/0295-5075/77/20004
Abstract
Relationship between the speed limit on the brane and in the bulk is discussed. We assume that the speed of light, similar to the 4-dimensional gravitational constant, is not a primary fundamental constant but depends on the gravitational potential of the brane. This opens the way to explain the hierarchy between the Plank and Higgs scales even within the simplest 5-dimensional model.
