Abstract: General relativity marked the beginning of modern cosmology and it has been
at the centre of many of the key developments in this field. In the present
review, we discuss the general-relativistic dynamics and perturbations of the
standard cosmological model, the Friedmann-Lemaitre universe, and how these can
explain and predict the properties of the observable universe. Our aim is to
provide an overview of the progress made in several major research areas, such
as linear and non-linear cosmological perturbations, large-scale structure
formation and the physics of the cosmic microwave background radiation, in view
of current and upcoming observations. We do this by using a single formalism
throughout the review, the 1+3 covariant approach to cosmology, which allows
for a uniform and balanced presentation of technical information and physical
insight.
