Overview
Recent developments in string theory indicates a fundamental problem in constructing de Sitter space and dark energy. I will review a new way to obtain de Sitter space compatible with string theory, where our universe is riding an expanding bubble of true vacuum in AdS5. I will also demonstrate how the model solves important problems in quantum cosmology.
