Abstract
It is shown that if spacetime undergoes a topology change then smooth matter fields described by maps into a target manfold N may not exist for all initial data. Examples are given for which N = Rp3. The result s are applied to Dyson's suggestion that particles lost during black h ole evaporation may reside in baby universes which have branched off f rom our universe.
