Query: Never Judge a Black Hole by Its Area   Christodoulou and Rovelli have shown that black holes have large interiors
that grow asymptotically linearly in advanced time, and speculated that this
may be relevant to the information loss paradox. We show that there is no
simple relation between the interior volume of an arbitrary black hole and its
horizon area. That is, the volume enclosed is not necessarily a monotonically
increasing function of the surface area.
