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.
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
