N2 - Big bang/crunch curvature singularities in exact CFT string backgrounds can be removed by turning on gauge fields. This is described within a family of SL(2)×SU(2)×U(1)x/ U(1)×U(1) quotient CFTs. Uncharged incoming wavefunctions from the "whiskers" of the extended universe can be fully reflected if and only if a big bang/crunch curvature singularity, from which they are scattered, exists. Extended BTZ-like singularities remain as long as U(1)x is compact.
