Query: Singular manifolds, topology change and the dynamics of compactification   We investigate the dynamics of the geometric transitions associated to
compactified spacetimes. By including the dynamics of gravity we are able to
follow the evolution of collapsing cycles as they attempt to undergo a topology
changing transition. Rather than achieving this singular geometry we find that
one of two scenarios occur, depending on the initial conditions. Either a
horizon forms, shielding a curvature singularity, or the cycle re-expands after
an initial contraction phase. For the case where a horizon forms we identify
the final state with a known analytic black-hole solution. We also show use our
results to demonstate a novel compactification mechanism, owing to the
asymptotic structure of this black-hole solution.
