Description
I will introduce Double Field Theory as the gravitational framework of string theory, describing the massless sector of closed strings. It is built on a novel differential geometry that goes beyond conventional Riemannian geometry and provides a testable, robust alternative to General Relativity. I will then discuss its relevance to late-time cosmological observations, with particular emphasis on its prediction of dynamical dark energy.
