Challenges for Superstring Cosmology
arXiv:hep-th/9212049 · doi:10.1016/0370-2693(93)90384-T
Abstract
We consider whether current notions about superstring theory below the Planck scale are compatible with cosmology. We find that the anticipated form for the dilaton interaction creates a serious roadblock for inflation and makes it unlikely that the universe ever reaches a state with zero cosmological constant and time-independent gravitational constant.
