摘要：

We show that a general solution of the Einstein equations that describes the approach to an inhomogeneous and anisotropic sudden spacetime singularity does not experience geodesic incompleteness. This generalizes the result established for isotropic and homogeneous universes. Further discussion of the weakness of the singularity is also included.
