Cosmological Dark Matter: a Review (the April Fool Edition)
  Evidence has continued to accumulate over the last few decades as to the
existence and nature of dark matter. Depending on the particle candidate, the
dark matter can exhibit one of several cosmologically defined models: hot dark
matter, cold dark matter, warm dark matter, self-interacting dark matter, and
fuzzy dark matter. In this paper I review the relevance and status of these
models, whether it is possible for more than one of these models to each
constitute some fraction of the dark matter, and discuss the prospects for
determining if any of these models can successfully describe the properties and
evolution of our own Universe.
