Scientific paper

We show that under some assumptions about the phase structure of the E8×E8 heterotic superstring, this theory will inevitably be afflicted with a cosmological domain-wall problem upon Calabi-Yau compactification (at or near the Planck scale). Several possible solutions are discussed, and we conclude that only inflation can resolve this problem. It thus becomes imperative, if we want to use this theory, to find an effective way to implement inflation in the superstring.
