This thesis considers a trapped characteristic initial value problem for the spherically symmetric Einstein-Maxwell-Scalar Field equations. For an open set of initial data whose closure contains Reissner-Nordstrom data, the future boundary of the maximal domain of development is found to be a lightlike surface along which the curvature blows up, and yet the metric can be continuously extended beyond it. This result is related to the strong cosmic censorship conjecture of Roger Penrose. |
