... We wish to compare the appearance of null geodesics in the cylindrical chart and the Born chart ... the line element by setting, we obtain from which we see that the minimal radius of a null geodesic is given by We can now solve to obtain the null geodesics as curves parameterized by an affine ... An outward bound radial null geodesic may be written in the form Transforming to the Born chart, we find that the trajectory can be written as Similarly for inward bound radial null geodesics ...
