Questions Concerning Schwarzschild's Solution of Einstein's Equations
  Now that an English translation of Schwarzschild's original work exists, that work has become accessible to more people. Here his original solution to the Einstein field equations is examined and it is noted that it does not contain the mathematical singularity normally associated with the existence of a black hole. Einstein's own views on this subject are considered also and it is seen that, at the very least, grave questions exist over the possible existence of these somewhat esoteric stellar objects.
