Fundamental Physics, the Swampland of Effective Field Theory and Early
  Universe Cosmology
  Cosmological inflation is not the only early universe scenario consistent
with current observational data. I will discuss the criteria for a successful
early universe cosmology, compare a couple of the proposed scenarios
(inflation, bouncing cosmologies, and the {\it emergent} scenario), focusing on
how future observational data will be able to distinguish between them. I will
argue that we need to go beyond effective field theory in order to understand
the early universe, and that principles of superstring theory will yield a
nonsingular cosmology.
