Two-Times physics is a reformulation of ordinary one time physics in a formalism that represents 1T dynamical systems in (d-1)+1 dimensions as various holographic images that describe the same 2T system in d+2 dimensions. It provides a framework in higher spacetime with 2T signature that encodes and unifies many aspects of physics, from simple quantum mechanics to strings. In this seminar we will study this procedure, see how it is free from any problem with unitarity or causality, thanks to appropriate gauge symmetries, and some applications will be shown, as the utility for describing twistors in various dimensions.
