In 1998, two groups of astrophysics discovered that the expansion of our Universe is accelerating, in direct contradiction with our expectations from General Relativity. This strange behaviour of our Universe could either be due to a new form of energy, called dark energy, or to a modification of the laws of gravity at large, cosmological scales. In this talk I will discuss how cosmological observations can be used to test the validity of General Relativity and the nature of dark matter. I will present novel observables, that can be used to search for deviations from the standard cosmological model.
