I've always admired the way Einstein approached gravity, -which had previously been treated as an a attraction, that is, a determined kinematics that had to be accounted for by a force-,from a completely different point of view, looking at it as the curvature that matter-energy produces in the trajectories of the rest of matter-energy. In a sense he switched kinematic notions by geometrical ones. Now purists are always stressing that since GR one shouldn't even talk about gravity as a force and that trajectories of bodies in gravitation fields are geodesics.(adsbygoogle = window.adsbygoogle || []).push({});

Now my question, has anybody tried that approach to the expansion of the universe,looking at it as the effect of a curvature of spacetime, that i guess would have to be opposite to the gravity field curvature? Of course the question would remain as to what would produce such a field?

If it is too wild a speculation, please let me know

Thanks
