Title: Non-Relativistic Gravity
Abstract: I will discuss the 1/c expansion of general relativity where c is the speed of light. At low orders this gives Newton-Cartan gravity and generalisations thereof. At higher orders (and weak fields) this can be matched with the post-Newtonian expansion used in gravitational wave physics. The 1/c expansion can also be used to systematically study quantum mechanical systems in fixed gravitational backgrounds. Finally, by adding a negative cosmological constant I will show that non-relativistic gravity can mimic the fluid/gravity correspondence for Galilean fluids on the boundary of a non-relativistic version of AdS spacetime.
