At weak coupling, the stopping distance of high-energy partons in QCD and QCD-like plasmas scales with energy as E^(1/2). One may investigate a similar question at strong coupling in QCD-like theories with gravity duals, such as N=4 SUSY Yang-Mills. Various authors have found that the maximum stopping distances in such strongly-coupled theories scales instead as E^(1/3). I will report on work with Diana Vaman showing that there is an important distinction between typical and maximum stopping distances, and the typical stopping distance scales with yet a different power law. I will also try to give some context contrasting different theoretical approaches to using AdS/CFT to study jet stopping and give my take on what, if anything, we learn about the theory of jet stopping from such investigations.
