We introduce a spatial averaging scheme and use it to study the evolution of spatial averages in large-scale simulations of cosmological structure formation performed with the Einstein Toolkit. The averages are performed on the spatial hypersurfaces of the simulation setup which. at least initially. represent the hypersurfaces of statistical homogeneity and isotropy. https://www.bekindtopets.com/special-pick-Grandpa-s-Best-Prairie-Hay-quick-pick/
