| description |
Our current cosmological model, backed by a large body of evidence from a variety of different cosmological probes (for example, see [1, 2]), describes a Universe comprised of
around 5% normal baryonic matter, 22% cold dark matter and 73% dark energy. While many
cosmologists accept this so-called concordance cosmology – the ΛCDM cosmological model
– as accurate, very little is known about the nature and properties of these dark components
of the Universe.
Studies of the cosmic microwave background (CMB), combined with other observational
evidence of big bang nucleosynthesis indicate that dark matter is non-baryonic. This
supports measurements on galaxy and cluster scales, which found evidence of a large
proportion of dark matter. This dark matter appears to be cold and collisionless, apparent
only through its gravitational effects.
