Recent years have seen great progress in probing gravitational physics on a vast range of scales, from the very largest cosmological scales to the microscopic ones associated with high energy particle physics. In this talk I will give a whistle stop tour of some of the different physical systems we can use to learn more about gravity in this way, with a focus on how we can use them synoptically to learn more about dark energy. Stops will include gravitational waves emitted by binary systems, the cosmic microwave background, large scale structure formation, and (theoretical) bounds on the behaviour of gravity on scales inaccessible to current experiments.
