 Fuzzy cold dark matter

Fuzzy Cold Dark Matter (FCDM) is a theoretical model in cosmology that seeks to address some challenges associated with cold dark matter (CDM) models, particularly at small scales. In the standard cosmological model, cold dark matter is envisioned as non-relativistic particles that interact only via gravity. Traditional CDM models have been successful in explaining large-scale structures of the universe, such as the distribution of galaxies and galaxy clusters.
