In this video, three cosmologists from the University of Geneva explain how they test the laws of gravity, and in particular Einstein's theory of General Relativity, in our Universe. You will learn about one of the biggest mysteries in cosmology, the accelerated expansion of the Universe, about novel theories of gravity, and about how measuring the distortion of time will reveal whether Einstein was correct.
