Cosmology (from the Greek kosmoV – kosmos – universe, logoV – logos – doctrine) is the science of space.
Cosmology is the science that studies the origin and evolution of the Universe as a whole. It is based on a set of empirical data and theoretical conclusions, which are based on fundamental physical theories – gravity, electromagnetic field (see Physical field), quantum mechanics, relativity and others. Objects located at a distance of more than 7-10 billion light years from Earth are objects located at cosmological distances.
