Online delivery mode, contact via newsgroups & email.

This Unit aims to provide an introduction to cosmology, including the physics of the early Universe, dark matter and dark energy, and the evolution of the observed large-scale structure.

After successfully completing this Unit, students should be able to:

  • have a conceptual knowledge of space-time and how it has evolved, its observational and theoretical basis and major unresolved questions;
  • understand basic cosmology concepts such as the big bang model and cosmic inflation, dark matter and dark energy, with the ability to discuss them in a non-technical way;
  • understand the tools with which we probe the large-scale structure of the universe, including large galaxy surveys and supercomputer simulations; and
  • research a cosmology topic in depth, using dependable sources of astronomical information on the internet and refereed journal articles.


  • Cosmology:
    special and general relativity; the hot “big bang” cosmology and alternative cosmologies; the different ‘flavours’ of dark matter and dark energy
  • The Early Universe:
    inflation; early universe particle physics; the cosmic microwave background radiation; nucleosynthesis
  • Large-scale Structure:
    structure formation and evolution; observational cosmology; using supercomputers to build synthetic Universes; the ultimate fate of the Universe
