  | This image was uploaded in the PNG image format. However, it contains visible lossy compression artifacts. These artifacts may have come from the JPEG format, from saving a single colorful image as GIF instead of PNG or from saving an animated GIF using the incorrect settings (See also Dither). If possible, please provide a superior version of this file, derived from a non-lossy source (or with artifacts removed). If applicable, please replace all instances of the artifact version throughout Wikimedia projects, tag the old version with one of these templates, and remove this tag.

Summary
| Description |
English: This figure depicts a null geodesic arc in the Born chart for Minkowski spacetime. In this chart, the world lines of Langevin observers, who ride on disks rotating with constant angular velocity, appear as vertical lines. The figure shows the world lines (blue vertical lines) of two Langevin observers who are riding on a rotating ring (the rim of a disk, if you like). The axis of cylindrical symmetry is shown as a green vertical line. The cylinder represents a surface of constant radius. The z coordinate is inessential and has been suppressed from this figure.
This particular null geodesic arc represents the world line of a radar blip sent from one ring-riding observer to the other. As the figure shows, this null geodesic (which appears as a straight line in the cylindrical chart) appears in the Born chart to be bent toward the center. This figure was created by User:Hillman using Maple to export a jpg image and eog to convert this to a png image. |

This graph image could be re-created using vector graphics as an SVG file. This has several advantages; see Commons:Media for cleanup for more information. If an SVG form of this image is available, please upload it and afterwards replace this template with {{vector version available|new image name}}.It is recommended to name the SVG file “Ring2Ring Born Chart.svg”—then the template Vector version available (or Vva) does not need the new image name parameter. |
