Penrose diagram and photon ray. Penrose diagrams (named after Roger Penrose) are a way to represent events occurring in spacetime,with time on one axis (left) and space on the other (bottom). The passage of a ray of light (a photon) is shown as a yellow arrow,which is at a 45-degree angle to the time axis and the same angle to the space axis. The lines in the diagram trace hyperbolas and converge at the corners labelled 'timelike infinity' and 'spacelike infinity'. The ray of light is shown reaching 'lightlike infinity'. Penrose diagrams can be used to represent the path of light rays and the spacetime properties of different types of black holes and other singularities. For this diagram without labels or the photon ray,see image C030/2325 | |
