This work studies the constraints that cosmic microwave background measurements set on such large distance modifications of the gravitational potential at large cosmological scales.
Abstract
It has been recently argued that higher dimensional gravity theories may manifest themselves not only at short microscopic distances but also at large cosmological scales. We study the constraints that cosmic microwave background measurements set on such large distance modifications of the gravitational potential.
