It order to understand the Universe and its evolution we need to understand the fundamental laws of nature. Radio astronomy is an ideal tool to provide insight into fundamental physics that is otherwise not obtainable. While the observed photons are of low energy, they are often the result of the most energetic processes in the cosmos. They carry information from the most extreme objects in the Universe (e.g. neutron stars), and their properties (namely polarisation and arrival times) reveal unique information about the only two fundamental long-range forces, electromagnetism and gravity. In this talk, I concentrate in particular on the study of gravitation and our current best description provided by the theory of general relativity and its alternatives.
