    Beyond (real) geodesics and extremal hypersurfaces in gravity
    Abstract: 
    Geodesics and extremal hypersurfaces play a critical role in the contemporary understanding of gravity. They compute certain correlation functions, various notions of entropy and, at least sometimes, complexity. I will discuss a new look at this venerable idea motivated by a lack of real extremal surfaces due to de Sitter expansion in cosmologies or timelike separation of boundary points (subregions) in anti-de Sitter holography. Based on 2305.11280 and work in progress with Fabio Ori and Alex Serantes.
