This series of talks is intended to give an appreciation of a construction applicable to a very wide range of physically interesting spacetimes.  Emphasis will be more on presentation of the issues involved (chiefly causal structure and topology), than on intricacy of detail, with the aim being to show how the causal boundary allows one to view a spacetime "from infinity", with a concrete picture of just what that infinity looks like.  We'll start with an introduction to what a spacetime is, from both mathematical and physical considerations.  A very basic notion of (pseudo-)Riemannian manifolds will be helpful, but the ideas should be clear even without that knowledge.
