Some remarks on a nongeometrical interpretation of gravity and the flatness problem

Abstract

In a nongeometrical interpretation of gravity, the metric $g_{\mu \nu }(x)={\eta }_{\mu \nu }+{\Phi }_{\mu \nu }(x)$ is interpreted as an {\em effective} metric, whereas ${\Phi }_{\mu \nu }(x)$ is interpreted as a fundamental gravitational field, propagated in spacetime which is actually flat. Some advantages and disadvantages of such an interpretation are discussed. The main advantage is a natural resolution of the flatness problem.
