If you have a question about this talk, please contact Shahar Hadar.

I will give an overview of the concept of symmetry in Einstein gravity ranging from very known to less known types of symmetry. I will show how these symmetries are the hint of a deeper structure which depends on the context but also has universal aspects. I will discuss in particular asymptotic BMS symmetry, conformal symmetry and the newer concept of symplectic symmetry. I will finally show how conformal symmetry controls physical phenomena in the vicinity of extremal Kerr black holes.
