  We examine the interplay between gravitational collapse and moduli stability
in the context of black hole formation. We perform numerical simulations of the
collapse using the double null formalism and show that the very dense regions
one expects to find in the process of black hole formation are able to
destabilize the volume modulus. We establish that the effects of the
destabilization will be visible to an observer at infinity, opening up a window
to a region in spacetime where standard model's couplings and masses can differ
significantly from their background values.
