The lambda-CDM model predicts a nearly flat spatial curvature at scales larger than the the scale of homogeneity of the universe. The calculation of many of its parameters depend on the cosmic distance ladder which in turn depend on many observational techniques and statistical comparisons.(adsbygoogle = window.adsbygoogle || []).push({});

My questions are:

1. Have all of these myriad calculations been done in a manner which does not presuppose a nearly flat spatial universe?

2. Many of the observations leading to both the lambda-CDM model and the cosmic distance ladder are taken at distances far below the scale of homogeneity where no assumption of nearly flat curvature can be made (voids and filaments, for example). How has this been taken into consideration?

All of the predictions of these models are impressive but have they been shown to be independent of presuppositions of flatness?

Any references to this topic would be appreciated.
