Excerpt: In astronomy and cosmology, dark matter is matter that is inferred to exist from gravitational effects on visible matter and gravitational lensing of background radiation, but that neither emits nor scatters light or other electromagnetic radiation (and so cannot be directly detected via optical or radio astronomy). Its existence was hypothesized to account for discrepancies between calculations of the mass of galaxies, clust...
