title: Evidence for maximal acceleration and singularity resolution in covariant loop quantum gravity.
abstract: A simple argument indicates that covariant loop gravity (spin foam theory) predicts a maximal acceleration and hence forbids the development of curvature singularities. This supports the results obtained for cosmology and black holes using canonical methods.
