Quantum fluctuations play a critical role in the formation and evolution of cosmic structures on large scales. Research indicates that primordial quantum diffusion generates non-Gaussian, exponential tails in the distribution of inflationary perturbations, which significantly influence the likelihood of forming collapsed structures, including primordial black holes. These effects extend to very-large-scale structures, increasing the probability of heavy clusters like “El Gordo” and large voids associated with the cosmic microwave background cold spot.
