Description

General relativity is a relativistic theory of gravity. It is based on two independent hypotheses: the equivalence principle, which allows us to describe the motion of matter in a curved spacetime; and Einstein’s equations, which predict how such a curvature is generated by material sources. After having introduced the necessary tools of Riemannian geometry, we will study the observable effects in the solar system (Mercury perihelion shift, light deflection, ...) and in binary pulsars, notably their energy loss due to gravitational radiation. All these predictions are in remarkable agreement with experimental data. We will end these lectures by a brief introduction to relativistic cosmology.
