This shows a Penrose diagram, which is a conformal compactification of 2D Minkowski space. The blue line is a geodetic line starting from the initial point with the chosen velocity.

Details

The coordinate lines are the equally distant Cartesian coordinate lines from Minkowski space; the distance between them is 0.5 units. Note that the shape of the lightlike geodetics is not affected by the conformal map.
