Comment on "Kerr Black Holes as Particle Accelerators to Arbitrarily High Energy"
arXiv:0911.2243 · doi:10.1103/PhysRevLett.103.239001
Abstract
It has been suggested that rotating black holes could serve as particle colliders with arbitrarily high center-of-mass energy. Astrophysical limitations on the maximal spin, back-reaction effects and sensitivity to the initial conditions impose severe limits on the likelihood of such collisions.
