In spite of its phenomenological successes, inflationary universe cosmology suffers from some conceptual problems. These motivate the search for a new paradigm of early universe cosmology based on new fundamental physics. I will present a toy model of early universe cosmology constructed from some basic principles of superstring theory. This model can explain current observations, and makes specific predictions which will allow the test of certain aspects of string theory in cosmological observations.
