Talk title: Our accelerating universe.

Our Universe is a remarkable laboratory for physics both at very high and very low energies. Whilst most of the history of our Universe is understood with a remarkable precision, the current state of our Universe remains mystifying, with its 95% of unknown dark matter and dark energy. Could the late-time acceleration of the Universe and the apparent discrepancy with standard particle physics be the first sign of the breakdown of gravity at very large distances? This may depend on the very nature of the graviton.

This Research Frontiers talk will be given by Claudia de Rham from the Theoretical Physics group.
