Filaments, Voids & Superclusters: Foundations

On scales much larger than individual clusters, galaxies form a cosmic web of filaments, sheets, nodes, and vast underdense voids. Large-scale structure tests cosmological models, dark matter, dark energy, neutrino masses, and the statistical properties of primordial fluctuations.
