well the most obvious answer is that the net force of gravitational attraction within a uniform shell is zero. For a force to exist the shell must be non-uniform, yet the expansion we can measure is all pretty homogenous and isotropic
The vacuum energy was found by someone to be 120 times to large to explain dark energy, I think I actually heard that on the naked astronomy podcast but I have no links to the source.
