...Aaron Sidney Wright The history of Penrose diagrams in the physics of General Relativity (GR) is presented. It is argued that the diagrams did conceptual work for physicists, providing a literal place for abstract, formal objects. Penrose diagrams were associated with the mathematics of conformal...
