Accelerating universes from compactification on a warped conifold

We find cosmological solution corresponding to compactification of 10d supergravity on a warped conifold that easily circumvents Gibbons's original "no-go" theorem, providing new perspectives for the study of supergravity or superstring theory in cosmological backgrounds. With stabilized volume moduli, the model can explain a physical universe undergoing an accelerated expansion in the 4d Einstein frame, for a sufficiently long time. The solution found in the limit that the warp factor dependent on the radial coordinate $y$ is extremized (giving a constant warping) is smooth and it supports a flat four-dimensional Friedmann-Robertson-Walker cosmology undergoing a period of accelerated expansion with slowly rolling or stabilized volume moduli.
