A naive understanding of the compact spaces of string theory tells me that an "energy audit" of the highly curved compact manifolds of string theory must have both large negative and positive energy contributions associated with the compact manifolds such that their sum approximately equals zero?

Naively then I would expect that if there were zero point energy from all the fields of the standard model this "extra" energy density would be small compared with the energy density contributions from the curved compact manifolds at each point of our nearly flat space?

My naive thought is that the extra energy from possible zero point energy of the standard model fields while very large is small in comparison with the positive and negative contributions of the compact hidden dimensions of string theory at each point of our large space dimensions. --->

So even without supersymmetry the zero point energy of fields is "small change"?

Thanks for any clarification!
