Description
We consider the dynamics of a four-dimensional universe using the pointlike field-theory effective action of superstrings. We use the boundary conditions of Hartle and Hawking and Vilenkin to solve the Wheeler-DeWitt equation. We find that under certain conditions the Universe will tunnel from a Euclidean regime to a Lorentzian regime. We study this process. We find that the inclusion of fermions (as extra internal degrees of freedom) due to supersymmetry can change the conclusion of Enqvist et al. where only bosonic fields were considered
