Description
We discuss possible consequences of a manifestly non-commutative and T-duality covariant formulation of string theory on dark energy, when the correspondence between short distance (UV) and long distance (IR) physics is taken into account. We demonstrate that the dark energy is dynamical, time-dependent, and we compute the allowed values of w_{0} and w_{a} given by w(a)=w_{0}+(1-a)w_{a}, which compare favorably to the most recent observations by DESI. From this point of view, the latest results from DESI might point to a fundamentally new understanding of quantum spacetime in the context of quantum gravity.
