Scalar collapses in flat and Reissner-Nordstrom
(RN) geometries are simulated. We examine the dynamics in the vicinities of
the central singularity of a Schwarzschild black hole and of the inner
horizon of a RN black hole. In simulating scalar collapse in RN geometry,
Kruskal-like coordinates are used with the presence of a scalar field being
taken into account. It is found that, besides near the inner horizons of RN
and Kerr black holes, mass inflation also takes place near the central
singularity in neutral scalar collapse. Approximate analytic expressions for
different types of mass inflation are partially obtained via a close
interplay between numerical and analytical approaches and an examination of
the connections between Schwarzschild black holes, RN black holes, neutral
collapse, and charge scattering. We argue that the mass inflations near the
central singularity and the inner horizon are related to the localness of the
dynamics in strong gravity regions. This is in accord with the Belinskii,
Khalatnikov, and Lifshitz conjecture.
