Abstract
The field equations of pregeometric theories of gravity are derived and analyzed, both without and with matter. After the spontaneous symmetry breaking that reduces the gauge symmetry of these theories à la Yang-Mills, a metric structure for spacetime emerges and the field equations recover both the Einstein and the Cartan field equations for gravity. A first exact solution of the pregeometric field equations is also presented. This solution can be considered as a pregeometric de Sitter universe and provides a possible resolution for the problem of the big bang singularity.
