Coarse-grained (CG) models provide a promising computational tool for investigating slow complex processes that cannot be adequately studied using more detailed models. However, unless the CG model is consistent with an accurate high-resolution model, the results of CG modeling may be misleading. The present talk describes a statistical mechanical framework that provides a rigorous “multiscale bridge” connecting models with different resolution.

The Cosmic Web is the fundamental spatial organization of matter on scales of a few up to a hundred
Megaparsec, scales at which the Universe still resides in a state of moderate dynamical evolution.
galaxies, intergalactic gas and dark matter exist in a wispy weblike spatial arrangement consisting of
dense compact clusters, elongated filaments, and sheetlike walls, amidst large near-empty void regions.

While the complex intricate structure of the cosmic web contains a wealth of cosmological
