This video covers the General theory of Relativity, developed by Albert Einstein, from basic simple levels (it s gravity, curved space) through to the concepts of how curved spacetime is represented by psuedoRiemannian manifolds with Lorentzian signature (that is, special relativity and minkowski space are the local tangent space), how matter and energy are represented by an energymomentum tensor, and how these two together obey the Einstein Field Equations. The solutions to the Einstein Field Equations (including the schwarzschild metric, kerr metric, freedmanlemaitrerobertsonwalker metric, etc) represent gravity around massive objects like the sun, earth, and black holes, but also the history and expansion and future evolution of the cosmos. The universe on a large scale is described by general relativity on a
