Hello, I'm DVdm. Your recent edit to the page Relativity of simultaneity appears to have added incorrect information, so I have removed it for now. If you believe the information was correct, please cite a reliable source or discuss your change on the article's talk page. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thank you. - DVdm (talk) 05:41, 8 May 2014 (UTC)

Note - This animation is not related to the subject of Relativity of simultaneity. It shows that the top observers (blue and grey) don't see light signals, sent out at two events (red, green), simultaneously whereas the bottom (yellow) observer does. Relativity of simultaneity is about events happening simultaneously (or not) for various observers who are in relative motion. It is not about signals sent out at events being seen simultaneously (or not) by various observers who are at rest w.r.t. each other. - DVdm (talk) 05:54, 8 May 2014 (UTC)
