Over the last century it has passed a variety of tests – all with flying colours. Still, our understanding remains incomplete. As the precision of our observations improve, we need a more detailed understanding on the theory side. Many of today’s questions – ranging from the violent dynamics of merging neutron stars emitting gravitational waves to the dark energy that causes the expansion of the universe to accelerate - demand a realistic description of matter. This inevitably brings us to consider fluid dynamics in the context of relativity. In this talk I will discuss the modern approach to relativistic fluid flows – drawing on examples from astrophysics and numerical simulations, and highlighting challenges that still need to be resolved. --------- Speaker Information Nils Andersson is Professor of Applied Mathematics, and Head of the General Relativity Group, at the University of Southampton. His research interests include relativistic superfluidity and elasticity, heat and dissipation in general relativity, and neutron star asteroseismology. --------- CUPS - Cambridge University Physics Society We are a student-run university society organising scientific talks and other events for our members and public.
