Overview
Core model: Quantum Fluctuations & Primordial Structure
In inflationary cosmology, microscopic quantum fluctuations are stretched to astronomical scales and become the initial perturbations from which galaxies and large-scale structure eventually grow. The observable outcome is a statistical field of tiny density and curvature variations rather than individual quantum events that can be reconstructed one by one.
