摘要：

The three-dimensional volume inside a spherical black hole can be defined by extending an intrinsic flat-spacetime characterization of the volume inside a two-sphere. For a collapsed object, the volume grows with time since the collapse, reaching a simple asymptotic form, has a compelling geometrical interpretation. Perhaps surprisingly, it is large. The result may have relevance for the discussion on the information paradox.
