Spherically Symmetric Inflation
  It is shown in this letter that in the framework of an inhomogeneous geometry
and a massive non self-interacting scalar field with spherical symmetry, one
needs a homogeneous patch bigger than a dizaine of horizons in order to start
inflation. The results are completly independent of initial conditions on the
spatial distribution of the scalar field. The initial condition on the metric
parameters are also justified. This is a generalization of the results obtained
in Ref.[1], showing that their conclusions are rather robust.
