Query: The dynamical stability of the static real scalar field solutions to the
  Einstein-Klein-Gordon equations revisited   We re-examine the dynamical stability of the nakedly singular, static,
spherical ly symmetric solutions of the Einstein-Klein Gordon system. We
correct an earlier proof of the instability of these solutions, and demonstrate
that there are solutions to the massive Klein-Gordon system that are
perturbatively stable.
