Could Shape replace Dark Energy

In imagining the universe as a spherical, closed shape, I am proposing an alternative way to explain cosmic expansion. Traditional models invoke dark energy to account for the observed acceleration, but the universe's shape itself might play a role.

If this curvature or "reverse depression" (the curvature is opposite to a gravity well) acts in a way that opposes the force of gravity, it could theoretically lead to expansion. This would imply that the geometric properties of spacetime could influence the universe's dynamics in a manner akin to an anti-gravity effect.

Intuitively it may be greater than mass gravity by a small margin if the universe is massive enough. maybe.
